Q: Can I use a {{A1}} with the Compact?

A: Basically, no.

Applicable quote from Neil-at-Bose

:We designed the L1 Compact to feature integrated bass and as a result the bass is not expandable as it is with L1 Model I or Model II.

:The L1 Compact's output passes a full-range signal therefore it would send alot of "undesired" mid range frequency to a Packlite system which would significantly alter the tonal balance of the system.

:If you are a customer that needs more bass a {{Model I}} or {{Model II}} system would be be a better fit.

=== Controls ===

We’ve designed the {{Compact}} with the goal of providing a simple user interface for both musicians and general purpose users. You will notice there is volume control for each channel but no overall master volume. This means that the power amp section is always at full gain. In this configuration the Channel 1 and Channel 2 volume controls are effectively acting as trim controls. The benefit of a trim control is that you don’t need to significant gain in order to drive the {{Compact}} to full output.

The {{Compact}} microphone Channel 1 is designed to work with a wide range of handheld microphones from popular microphones like a Shure Beta 58A all the way to lower sensitivity microphones like the Sennheiser e8155. As you may know sensitivity can vary between microphones so we’ve elected to include a higher amount of gain on the microphone channel.

In order to maximize signal to noise (when using the {{Compact}} Channel 1 Microphone Channel) we recommend that you determine the loudest level that is required for your room/application and follow the steps below.

# Plug in your microphone to Channel 1

# Turn the {{Compact}} Channel 1 Volume/Trim to 9 o’clock

# Speak into the microphone at your loudest volume and softest volume

# Adjust the Channel 1 Volume/Trim control to a setting that will work for your loud and soft vocal passages.

# Remember since this is effectively a trim control (and the master is at full) you don’t need to build additional headroom into the system.

# Additional tip: In most cases, the Channel 1 Volume/Trim Preamp has more gain than you will ever need, so if you don’t need the extra gain, don’t use it as it will only introduce noise.

=== Setting the Volume and the LEDs ===

Question: What do the Signal/Clip indicators (green/red lights) on the {{Compact}} mean.

Answer:

: For both Channel 1 and Channel 2 the Red LED indicates that the Limiter is being activated.

:Blinking red signifies that you are achieving maximum usable audio output

:Solid red indicates that the system is clipping and volume should be reduced

Question: What happens when the Compact is running at full-out. That is, is it going to audibly clip, compress or something else.

Answer:

:The {{Compact}} limiters are set to allow some audible clipping to enable a performer to hear when the unit is topped out and have a better feel for its maximum output range.

==== Differences in Volume Settings ====

[[Image:Compact Volumes New Original.jpg|right]]

There have been reports that the volume controls behave differently when comparing early production units and later ones.

:I can see how it could be possible that there could be subtle differences in the position of the level controls between early and newer production units, but this variance should be very small. We did receive some initial comments that suggested that the system got loud very quickly, therefore the pot taper on the newer units is slightly different. The amount of usable volume remains unchanged and there were no adjustments to the tonal balance of the system. — Neil-at-Bose, January 2010<ref>Neil-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/3976055944/m/315102434?r=545107944#545107944 Why do two Compacts Sound Different] January 2010 </ref>

=== Positioning ===

From the {{Compact Owners Guide}}

[[Image:DistanceCompact.jpg]]

The {{Compact nl}} does not play as loud, nor as deep in bass, nor does it project as far into a room as either the {{Model I}} or {{Model II}}. If you are used to performing with a {{Model I nl}} or {{Model II nl}} you may find that you have to run the {{Compact nl}} louder on stage than the others to project into the room.

The {{Compact nl}} has extremely wide horizontal dispersion (like the {{Model II}}. If you are using a vocal microphone you will probably have better gain-before-feedback with the {{Compact nl}} off to the side a bit so the microphone is aimed away from the speaker array on top of the {{Compact nl}}.

First of all, the L1® Compact is very different in basic nature from the two original ones. It has a head-high vertically-divergent array that is ultra-wide horizontally. the vertical angle is narrow enough so its sound pressure fall-off with distance is not as severe as, say, a guitar amp, but it's somewhat greater than an L1 I or II. We have data galore taken on the ~~L1C~~ array, but to a musician, ~~its~~ not only useless, it's confusing. Thinking about this stuff intellectually leads nowhere.

So, forgetting all this, The ~~L1®~~ Compact sounds the same and, from personal experience playing and singing solo, it feels the same. When I played (this seems to be a typical configuration), the system was off to the side 5' and back of me 4'. It is louder when you get on top of it (unlike the L1) so you need to get a little further from it. But not much.

It is louder when you get on top of it (unlike the L1) so you need to get a little further from it. But not much.

It's very well behaved and it's easy to arrive at an organically-correct distance from it. But; bottom line; it really behaves like the other L1's. I know it has less overall output than the big ones, but I never felt that limit playing demos for a variety of audiences prior to yesterday's launch. I know the system will allow me to entertain at a level I'm happy with in our live music theater. I really don't want more level from it. Our theater holds over 100 and is acoustically treated to be pretty dry. Charlie Farrin did the same on a number of occasions. He's an experienced pro, playing guitar and singing to demonstrate for other audiences. As an audience member listening to Charlie, I was delighted with the sound quality and level. It was exceptionally articulate musically and I understood all his words, on songs I wasn't familiar with.

I'm guessing if you're playing guitar or keys and singing (a solo gig), you can play for 100 with great quality. I never thought once about the capacity of the LF. My keys are never exaggerated on the low end and I want them to sound like, for instance, a real piano or a Rhodes Suitcase. I'm guessing an organ player playing a heavy bass line and singing, like a solo gig, might put the thing to the test. I haven't experienced this and don't do it myself.

== AC Power ==

=== Battery Power ===

This is especially for those who want to run the L1 Compact with an inverter connected to a car battery or from a Power Pack.

Note: The L1 Compact accepts all AC Power In voltages from 100V to 240V, the different part numbers change the power cord in the box.

Here is the AC Power in levels we have measured on the L1 Compact, please realize that these are approximate and vary greatly with audio content.

<pre>

Power 230V 120V 100V

Idle: 12W 0.06A 0.1A 0.12A

(no audio)

Filling a room: 30W 0.14A 0.25A 0.3A

Full Out: 60W 0.3A 0.5A 0.6A

(Red LED blinking)

</pre>

Note: The AC line power in can peak around 100W during a loud burst.

We have also tested the L1 Compact with several DC to AC Inverters. Avoid modified sine wave inverters. Pure sine wave inverters are preferable.

I recommend that an inverter of at least 300W be used. Less then that has not been tested.

Here are measurements we took, realize this also includes the inverter efficiency:

<pre>

Current from 12V Battery to Inverter

Idle: 12W 1.5 Amps from battery

Filling a room: 30W 3 Amps from battery

Full Out: 60W 6 Amps from battery

</pre>

There are also "Power Packs" available which have the battery built-in with the inverter.

To find out how long one of the "Portable Power Packs" will run divide the amp hour rating of the battery by the amps from the list above (usually divide by 3), this is assuming it uses a 12V battery.

There was a follow-up question about the impact of using a {{T1}} with the {{Compact}}. Expect that adding a {{T1}} may draw as much power as the {{Compact}} meaning that your power requirements may be double what is show above.

<html>

</html>

What an interesting inquiry! First I'll note the official maximum wattage spec for L1 Compact is 200 watts max. Keep in mind, maximum power draw would only occur with the L1 playing at maximum, blaring volume. Normal power draw at "normal" volumes will be something much less than 200 watts.

<br>The T1 power supply rating of 81-100 VA is the same as 81-100 watts (volts times amps is watts). So I consider T1 maximum power draw 100 watts.

<br>So based on these official specs this setup presents a maximum draw of 300 watts. A good rule of thumb for an inverter would be to oversize by at least a factor of two so at least 600 watts for the inverter.

<br>Keep in mind official specs can be conservative (as Tom's lower wattage numbers show). Feel free to measure your power draw at home using regular utility and/or inverter power. If you have access to a kill-a-watt or similar, it will tell you how much power in watts your Compact and T1 are drawing with your sources at your levels. Sometimes real-world testing is best.

<br>

Thanks and good luck!

[[Image:CompactLineOut.gif|right]]

=== Rear panel outputs ===

¼-inch output – Mono analog output that accepts either ¼ inch Tip-Ring-Sleeve balanced or

Tip-Sleeve unbalanced cables.

Can be used to link multiple {{Compact}} systems together

by connecting the ¼-inch output from one {{Compact}} system to the ¼-inch input

(Channel 2) on a second {{Compact}} system. This will provide additional coverage

in larger spaces. You can also use the ¼-inch output to connect to a house PA

system and use the {{Compact}} system as your personal monitor.

==== Output Level ====

¼ inch (6.3 mm) jack: Nominal +2.2 dBu, Max +20 dBu

Note: Using a TS unbalanced cable will result in a drop in the audio level of -6dBu.

Source: Page 6 of the {{Compact Owners Guide}}

=== ¼ inch jack output EQ ===

The Compact has a balanced line-out that is a mix of all the inputs, post level and EQ settings on the input panel. The signal at the line out will be full range down to 30 Hz. There is an exception. The Channel 2 input will be band-pass above 60 Hz (nothing below that) when the ToneMatch® switch is ON (up position). The other inputs are unaffected.

:If the Tonematch switch is engaged on Channel 2 then sources connected to the 1/4" input will not pass anything below 60Hz out of the line outputs.

:This does not apply to the 1/8" and RCA inputs which will pass information down to 30Hz through the line outputs regardless of where the ToneMatch switch is positioned.

:If the ToneMatch switch is set to line level sources connected to the 1/4" input will also pass information down to 30Hz through the line outputs.

=== Tip for Separating the Extensions ===

== Static Electricity ==

Some Compact owners report static electricity sparks when removing the cover from the Power Stand.

Here is a note from Neil-at-Bose

:It sounds like the sparks are from the cover to the plastic case. They will dissipate without a problem. Engineering thoroughly tested the L1 Compact with ESD (electro static discharge) hits to all surfaces and the most common result is that absolutely nothing happened. On some discharges an audio crackle can be heard.

:We would like to assure you that this will not damage the system.

+[[Image:Compact Volumes New Original.jpg|right]]
+There have been reports that the volume controls behave differently when comparing early production units and later ones.
+:I can see how it could be possible that there could be subtle differences in the position of the level controls between early and newer production units, but this variance should be very small. We did receive some initial comments that suggested that the system got loud very quickly, therefore the pot taper on the newer units is slightly different. The amount of usable volume remains unchanged and there were no adjustments to the tonal balance of the system. &mdash; Neil-at-Bose, January 2010<ref>Neil-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/3976055944/m/315102434?r=545107944#545107944 Why do two Compacts Sound Different] January 2010 </ref>
+=== Positioning ===
+From the {{Compact Owners Guide}}
+[[Image:DistanceCompact.jpg]]
+The {{Compact nl}} does not play as loud, nor as deep in bass, nor does it project as far into a room as either the {{Model I}} or {{Model II}}.  If you are used to performing with a {{Model I nl}} or {{Model II nl}} you may find that you have to run the {{Compact nl}} louder on stage than the others  to project into the room.
+The {{Compact nl}} has extremely wide horizontal dispersion (like the {{Model II}}. If you are using a vocal microphone you will probably have better gain-before-feedback with the {{Compact nl}} off to the side a bit so the microphone is aimed away from the speaker array on top of the {{Compact nl}}.

-First of all, the L1® Compact is very different in basic nature from the two original ones. It has a head-high vertically-divergent array that is ultra-wide horizontally. the vertical angle is narrow enough so its sound pressure fall-off with distance is not as severe as, say, a guitar amp, but it's somewhat greater than an L1 I or II. We have data galore taken on the L1C array, but to a musician, its not only useless, it's confusing. Thinking about this stuff intellectually leads nowhere.

-So, forgetting all this, The L1® Compact sounds the same and, from personal experience playing and singing solo, it feels the same. When I played (this seems to be a typical configuration), the system was off to the side 5' and back of me 4'. It is louder when you get on top of it (unlike the L1) so you need to get a little further from it. But not much.

 It's very well behaved and it's easy to arrive at an organically-correct distance from it. But; bottom line; it really behaves like the other L1's. I know it has less overall output than the big ones, but I never felt that limit playing demos for a variety of audiences prior to yesterday's launch. I know the system will allow me to entertain at a level I'm happy with in our live music theater. I really don't want more level from it. Our theater holds over 100 and is acoustically treated to be pretty dry. Charlie Farrin did the same on a number of occasions. He's an experienced pro, playing guitar and singing to demonstrate for other audiences. As an audience member listening to Charlie, I was delighted with the sound quality and level. It was exceptionally articulate musically and I understood all his words, on songs I wasn't familiar with.
-I'm guessing if you're playing guitar or keys and singing (a solo gig), you can play for 100 with great quality. I never thought once about the capacity of the LF. My keys are never exaggerated on the low end and I want them to sound like, for instance, a real piano or a Rhodes Suitcase. I'm guessing an organ player playing a heavy bass line and singing, like a solo gig, might put the thing to the test. I haven't experienced this and don't do it myself.

+== AC Power ==
+=== Battery Power ===
+This is especially for those who want to run the L1 Compact with an inverter connected to a car battery or from a Power Pack.
+Note: The L1 Compact accepts all AC Power In voltages from 100V to 240V, the different part numbers change the power cord in the box.
+Here is the AC Power in levels we have measured on the L1 Compact, please realize that these are approximate and vary greatly with audio content.
+<pre>
+                Power   230V   120V   100V
+          Idle:  12W   0.06A   0.1A   0.12A
+       (no audio)
+Filling a room:  30W   0.14A   0.25A  0.3A
+      Full Out:  60W   0.3A    0.5A   0.6A
+(Red LED blinking)
+</pre>
+Note: The AC line power in can peak around 100W during a loud burst.
+We have also tested the L1 Compact with several DC to AC Inverters. Avoid modified sine wave inverters. Pure sine wave inverters are preferable.
+I recommend that an inverter of at least 300W be used. Less then that has not been tested.
+Here are measurements we took, realize this also includes the inverter efficiency:
+<pre>
+Current from 12V Battery to Inverter
+          Idle: 12W   1.5 Amps from battery
+Filling a room: 30W   3 Amps from battery
+      Full Out: 60W   6 Amps from battery
+</pre>
+There are also "Power Packs" available which have the battery built-in with the inverter.
+To find out how long one of the "Portable Power Packs" will run divide the amp hour rating of the battery by the amps from the list above (usually divide by 3), this is assuming it uses a 12V battery.
+[http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/745104421?r=782102261#782102261 Source: Tom-at-Bose]
+There was a follow-up question about the impact of using a {{T1}} with the {{Compact}}. Expect that adding a {{T1}} may draw as much power as the {{Compact}} meaning that your power requirements may be double what is show above.
+<html>
+<blockquote>
+</html>
+What an interesting inquiry! First I'll note the official maximum wattage spec for L1 Compact is 200 watts max. Keep in mind, maximum power draw would only occur with the L1 playing at maximum, blaring volume. Normal power draw at "normal" volumes will be something much less than 200 watts.
+<br>The T1 power supply rating of 81-100 VA is the same as 81-100 watts (volts times amps is watts). So I consider T1 maximum power draw 100 watts.
+<br>So based on these official specs this setup presents a maximum draw of 300 watts. A good rule of thumb for an inverter would be to oversize by at least a factor of two so at least 600 watts for the inverter.
+<br>Keep in mind official specs can be conservative (as Tom's lower wattage numbers show). Feel free to measure your power draw at home using regular utility and/or inverter power. If you have access to a kill-a-watt or similar, it will tell you how much power in watts your Compact and T1 are drawing with your sources at your levels. Sometimes real-world testing is best.
+<br>
+Thanks and good luck!

+=== &frac14; inch jack output EQ ===
+The Compact has a balanced line-out that is a mix of all the inputs, post level and EQ settings on the input panel. The signal at the line out will be full range down to 30 Hz. There is an exception. The Channel 2 input will be band-pass above 60 Hz (nothing below that) when the ToneMatch® switch is ON (up position). The other inputs are unaffected.
+:If the Tonematch switch is engaged on Channel 2 then sources connected to the 1/4" input will not pass anything below 60Hz out of the line outputs.
+:This does not apply to the 1/8" and RCA inputs which will pass information down to 30Hz through the line outputs regardless of where the ToneMatch switch is positioned.

+:It sounds like the sparks are from the cover to the plastic case. They will dissipate without a problem. Engineering thoroughly tested the L1 Compact with ESD (electro static discharge) hits to all surfaces and the most common result is that absolutely nothing happened. On some discharges an audio crackle can be heard.
