== Connections from a Mixer ==
== Connecting Other Equipment (inputs) ==
This section is an overview of connections you can make from a mixer (mixing desk) to the {{PS1}}. For specific examples see: [[Mixer]]s.
===Connector Types===
This section is an overview of connections you can make from a other equipment (mixer, music storage device, etc.) to the {{PS1}}.


=== XLR (balanced) to XLR (balanced) ===
Audio equipment inputs and outputs are either balanced (three conductors) or unbalanced (two conductors). Balanced signals have the potential to be more resistant to hum and noise.

(balanced to balanced) should be fine. This is the same kind of cable you would use to connect a microphone.
In addition different kinds of connectors are used for the input and outputs.
 
Here are the main types:
* XLR, male (prongs) and female (receptacles for prongs), usually balanced
* ¼ inch, male (shaft) and female (receptacle for shaft), balanced (tip-ring-sleeve on shaft) or unbalanced (tip-sleeve)
* RCA, male and female, always unbalanced
* 1/8 inch mini (male and female), balanced (tip-ring-sleeve on shaft) or unbalanced (tip-sleeve)
 
 
===Cable Types and Connection to the PS1===
 
Note: The {{PS1}} Channels 1 and 2 &frac14; inch inputs are unbalanced. There are many kinds of cables that will '''work''' but no connection that uses the &frac14; input will be balanced because the internal connection is unbalanced.
 
 
'''XLR (balanced) to XLR (balanced)'''
 
[[Image:XLRXLRMF.png|300 px]]
 
This is the same as a microphone cable but is also used to connect a balanced line output to a balanced line input.


Things you can do if the signal is too hot (you are having trouble with the input clipping on the Bose System)...
* check to see if there is a 'pad' built-in on the mixer (most Mackie mixers have this on the panel beside the XLR outs)
* turn down the main outs on the mixer
* use a 20 dB [[Pad]] (attenuator) between the mixer and the Bose System.

(unbalanced to unbalanced) is fine:

You could have difficulty if you are running long lines (and losing signal or picking up noise). If you are, consider using shorter cable runs, or running an balanced line. To do this you can use a short unbalanced cable to a DI (to convert from unbalanced to balanced) and run from there: XLR to XLR (balanced to balanced) to the Bose System.
These cables are prone to noise if you are running long lines (greater than 20 feet). Consider using shorter cable runs, or running a balanced line. You can use a short unbalanced cable to a [[DI|DI or Direct Box]] (to convert from unbalanced to balanced) and run an XLR to XLR cable from the Direct Box to the Bose System.


=== Balanced to Unbalanced ===
The {{PS1}} Channels 1 and 2 &frac14; inch inputs are unbalanced. There are many kinds of cables that will '''work''' but no connection that uses the &frac14; input will be balanced because the internal connection is unbalanced.

This should work, but likely no better than a simple ¼ Inch Tip-Sleeve to Tip-Sleeve  cable. This is because the ¼ Inch input on the Bose System is Tip-Sleeve (unbalanced) anyway.

This should work well if the mixer output is +4 dBU as this is a reasonable match for signal level, with any of the  ¼ Inch inputs for Power Stand Channels 1, 2, 3, 4. Those inputs are all unbalanced, so there is no particular advantage to using this balanced cable compared to an unbalanced cable. There is no particular benefit to using this kind of cable as compared to the one below.
No issues but because all four ¼ Inch inputs on the PS1 inputs are unbalanced, this cable provides no advantage over an unbalanced cable.

This is probably a specialty cable that was supplied with the instrument. It is intended for a microphone input on a mixer. This should work fine with the Bose System.

This is often used as a Microphone adaptor cable.
This is often used as a Microphone adaptor cable. Can be problematic. Sometimes you see these being used for home karaoke machines and are not suitable for professional use.
The ¼ Inch  input was designed for high impedance line-level inputs and may not provide enough gain for a microphone which is probably low impedance.

This is probably an Instrument adaptor.
This is probably an Instrument adaptor. May be problematic. You are probably running an impedance mismatch (high impedance from the instrument to low impedance balanced XLR).
 


This may not work particularly well. You are probably running an impedance mismatch (high impedance from the instrument to low impedance balanced XLR).
=== Things you can do if the signal is too high for PS1 ===
* check to see if there is a 'pad' built-in on the mixer (most Mackie mixers have this on the panel beside the XLR outs)
* turn down the main outs on the mixer
* use a 20 dB [[Pad]] (attenuator) between the mixer and the Bose System.
