{{FAQItem
    | question = How much coverage can I get?
    | answer =
Several factors determine how large an area you can cover with your sound.
* The distance to the listener farthest away
* The noise level in the listening area
* Walls and boundaries that affect reflections that support low frequencies


Use the chart below to see the performance over distance of the different models. This will help you to predict how well you can be heard at a distance.

  |question = L1 Pro32, can I use only the lower section of the array?
<!-- Can I operate the L1 Pro32 with only the lower section of the line array? Sometimes there is not sufficient height to use the full array  -->
  |answer  =
Yes
:The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32<br>Source: Page 7 of the [[Media:L1 Pro32 Owners Guide.pdf|L1 Pro32 Owners Guide]]


* For best results, ensure the array is at ear level for listeners
* The L1 Pro32 automatically adjusts the level of the bass output to maintain the appropriate spectral balance.


:It’s a valid use case to use only the bottom array section. In fact, the EQ automatically adjusts to compensate.<br>[https://www.facebook.com/groups/BoseL1/posts/10159778256657446/?comment_id=10159778526867446&reply_comment_id=10159779126107446 Craig Small - Bose]
; Half Stack Not Recommended for Small Gigs
Running only the lower section of the Line Array is a workaround when there isn't enough ceiling clearance to use both sections. For small gigs, turn down the volume on the L1 Pro32, don't run without the top section of the array because
* You'll need to elevate the system so the array is at ear level for the audience. Otherwise, the sound will be muffled
* You will reduce your projection over distance. The sound will drop off more over distance. 
* You may need to turn up the volume louder than if you were using the full array. As a result, you increase the likelihood of feedback.

=== ToneMatch Mixers (T1/T4S/T8S) and the L1 Pro ===
{{FAQList
|content=
  {{FAQItem
  | question = How do I connect a T4S to the L1 Pro
  | answer =
In addition to the three inputs on the L1 Pro systems, you can add a T4S. When you do,
* The inputs and controls on the T4S operate independently from the inputs and controls on the L1 Pro
* The three inputs on the L1 Pro operate independently of the T4S. The operation of the controls of the L1 Pro is the same whether or not a T4S is connected via the ToneMatch port.
 
You can connect from the T4S to one or two L1 Pro systems using the ToneMatch ports.
 
For full details see: [[T4S to L1 Pro]]

In addition to the three inputs on the L1 Pro systems, you can add a T8S. When you do,
* The inputs and controls on the T8S operate independently from the inputs and controls on the L1 Pro
* The three inputs on the L1 Pro operate independently of the T8S. The operation of the controls of the L1 Pro is the same whether or not a T8S is connected via the ToneMatch port.
 
You can connect from the T8S to one L1 Pro system using the ToneMatch port. There are also XLR and {{14TRS}} outputs.

{{FAQItem
|question = How do I connect a monitor?
|answer  =
* You can connect the '''L1 Pro Line Out''' to a monitor. 
<html><blockquote></html>
{{L1 Pro Line Out}}
<html></blockquote></html>
* If you have an '''S1 Pro''', see [[L1 Pro to S1 Pro]] 
* If you have an '''S1 Pro+''', see [[L1 Pro to S1 Pro+]] 
* If you prefer to run your inputs to the '''S1 Pro+''' and send the output to the L1 Pro, see [[S1 Pro+ To L1 Pro]]
* If you have a mixer, you may prefer to send the monitor mix from the mixer to the monitors instead of the L1 Pro Line Out
 
The L1 Pro was designed to be placed behind the performers. 
If you can do that, you may not need a monitor — you should be able to hear yourself clearly.

{{FAQItem
|question = How do I connect a third-party mixer?
|answer =
Use the '''Mixer Mono Output''' and connect it to '''L1 Pro Channel 3'''.
 
If the mixer does not have a mono output, pan all inputs hard LEFT and use the LEFT output. We will now refer to that as the Mixer Mono Out.


The Channel ToneMatch Setting (MIC/INST/OFF) affects only the ToneMatch Preset applied to the input.  
If the mixer has XLR outputs:  
It does not affect input sensitivity or gain applied to the signal.
: Mixer Mono Out → {{XLRTRS}} → L1 Pro Channel 3


'''Channel ToneMatch Button:'''  
If the mixer has {{14TRS}} outputs:   
Select the ToneMatch preset for an individual channel.  
: Mixer Mono Out → {{14TRS}} → L1 Pro Channel 3
Use MIC for microphones and INST for acoustic guitar. 
The corresponding LED will illuminate white while selected.

   |question = 1. Some mixers can output mic‑level on XLR — most cannot
   |question = 1. Some mixers have a '''MIC/LINE''' or '''‑20 dB''' switch on the XLR output
   |answer  = If your mixer allows switching its XLR outputs from Line to Mic, then it may work.
   |answer  =  
But this is uncommon. 
If your mixer can switch its XLR output to '''MIC''' or '''‑20 dB''', then engage that switch and the XLR‑to‑XLR connection should work.
Using XLR → ¼″ (6.3 mm) Tip‑Ring‑Sleeve into Channel 3 is far more reliable.
 
If not, use Mixer Mono Out → {{XLRTRS}} → L1 Pro Channel 3.

{{FAQItem
  |question = Why are the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Inputs on channels 1 and 2 louder than the 1/4-inch (6.3 mm) Tip-Ring-Sleeve Input on Channel 3
|question = Why are the {{14TRS}} inputs on Channels 1 and 2 louder than the {{14TRS}} input on Channel 3?
  |answer  = By design, the input sensitivity on channel 3 1/4-inch (6.3 mm) Tip-Ring-Sleeve is lower than on channels 1 and 2, so that when using line-level inputs, channel 3 is less likely to clip. You can get the same output from channel 3, but you may have to turn up the volume control higher to do it. You are most likely to notice this difference when connecting a third-party mixer to the L1 Pro. For more information see [[Mixer to L1 Pro]]

By design, the input sensitivity of the Channel 3 {{14TRS}} input is lower than the {{14TRS}} inputs on Channels 1 and 2. 
  {{FAQItem
This allows Channel 3 to handle '''line‑level''' sources with less risk of clipping.
  |question = How do I connect one L1 Pro to another L1 Pro (Daisy chain)?
 
  |answer  = Use an XLR female to 1/4 inch (6.3 mm) Tip-Ring-Sleeve to connect the L1 Pro Line Out to a second L1 Pro (any model) channel three. For complete details see [[L1 Pro Daisy Chain]]
You can achieve the same overall output level from Channel 3, but you may need to turn the Channel 3 volume control higher to do it.
  }}
 
This difference is most noticeable when connecting a third‑party mixer to the L1 Pro.
 
People tend to hear louder as better, so you may prefer to use Channels 1 and 2 instead of 3, but you can get the same result by turning up the volume on Channel 3, leaving the other channels available.

=== Multiple L1 Pro Systems ===
{{FAQList
| content =
{{FAQItem
|question = What can I do with multiple L1 Pros?
|answer  =
Multiple L1 Pros can be used together, but each system still operates independently.
 
;What they can do
* Pass audio from one unit to another using the '''L1 Pro Line Out''' (Daisy Chain)
;: With a mixer
* Play the same signal if you feed each unit from a mixer 
* Work as a stereo pair when fed LEFT and RIGHT outputs from a mixer 
 
'''What they can’t do'''
* Share their internal inputs with each other 
* Combine all inputs from two units into one system 
* Link wirelessly over Bluetooth (Bluetooth is receive‑only)
 
For details on specific setups, see the related questions below.
}}
{{FAQItem
|question = How do I connect one L1 Pro to another L1 Pro (daisy chain)?
|answer  =  
Use {{XLRTRS}} to connect
:'''From''' the first '''L1 Pro Line Out'''
:'''To''' the second '''L1 Pro Channel 3''' {{14TRS}} input.
 
For complete details, see [[L1 Pro Daisy Chain]].
}}
 
{{FAQItem
|question = Can I use Bluetooth to connect two L1 Pros?
|answer  =
No
 
L1 Pro systems can receive Bluetooth audio from a Bluetooth source (for example, a phone, tablet, or computer). 
They cannot send Bluetooth to another L1 Pro, and even if they could, the latency (delay) would make this unusable in a live sound setting.
 
For more information see [[L1 Pro Daisy Chain]]
}}
{{FAQItem
|question = Can I run two L1 Pros as a single mono system?
|answer  =
You can send the output of one L1 Pro to another ([[L1 Pro Daisy Chain|Daisy Chain]]), but you can't send the output of the second one back to the first.
That is: You cannot take the three inputs on each L1 Pro and hear all six inputs through both units.
 
Each unit only plays the signals connected to its own inputs.
 
If you want both L1 Pros to play the same mono mix, use a '''mixer''' and send the same output to each unit:
:'''From''' the mixer '''Mono Output''' → '''L1 Pro (Left) Channel 3''' {{14TRS}} input 
:'''From''' the mixer '''Mono Output''' → '''L1 Pro (Right) Channel 3''' {{14TRS}} input 
 
This gives you two identical mono feeds, but the L1 Pros still operate as '''separate''' systems.
 
For more details, see [[Dual Mono]].
}}
{{FAQItem
|question = How do I connect two L1 Pros for stereo?
|answer  =
To run two L1 Pros in stereo, send the LEFT and RIGHT outputs from your mixer to each L1 Pro separately.
 
:'''From''' the mixer '''LEFT Output''' → '''L1 Pro (Left) Channel 3''' {{14TRS}} input 
:'''From''' the mixer '''RIGHT Output''' → '''L1 Pro (Right) Channel 3''' {{14TRS}} input 
 
Each L1 Pro then reproduces its own channel (Left or Right), creating a stereo pair.
 
For more details, see [[Mixer to L1 Pro]].
}}
{{FAQItem
|question = Can I connect my L1 Pros so they share inputs?
|answer  =
No
* You cannot take the three inputs on each L1 Pro and hear all six inputs through both units.
* While you can daisy chain the inputs of the first L1 Pro to a second L1 Pro, you cannot send the inputs of the second L1 Pro back to the first. Doing so will create a feedback loop.
