| question = How much coverage can I get?

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

===Inputs and Connections===
{{FAQList
| content =
{{FAQItem
|question = Is MIC/INST/OFF the same as a MIC/LINE switch?
|answer =
'''No. The MIC/INST/OFF switch is NOT a MIC/LINE selector like those found on many powered loudspeakers.'''

The switch does '''not''' change input sensitivity or gain. <br>It affects only the ToneMatch Preset applied to the input.
{{ToneMatch Switch}}
}}
{{FAQItem
|question = Does the MIC/INST/OFF switch change the input gain?
|answer =
'''No. The MIC/INST/OFF switch does not change input sensitivity or gain.'''

It only selects the ToneMatch Preset applied to the input. <br>It does '''not''' adjust the channel’s gain staging or level.
{{ToneMatch Switch}}
}}
{{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.
For more about that, see [[The L1® Approach and the History Of Amplification]].
}}
{{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.

If the mixer has XLR outputs:
: Mixer Mono Out → {{XLRTRS}} → L1 Pro Channel 3

If the mixer has {{14TRS}} outputs:
: Mixer Mono Out → {{14TRS}} → L1 Pro Channel 3

For more details, see [[Mixer to L1 Pro]].
}}
{{FAQItem
|question = Can I use XLR cables from my mixer into Channels 1 or 2?
|answer =
{{FAQItem
|question = You can, and it ''might'' work. Click for details
|answer =
And yes, there are even pictures of this in the L1 Pro manuals.

However, using XLR‑to‑XLR connections from a mixer into Channels 1 or 2 can lead to problems.

{{FAQItem
|question = 1. Some mixers have a '''MIC/LINE''' or '''‑20 dB''' switch on the XLR output
|answer =
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.

If not, use Mixer Mono Out → {{XLRTRS}} → L1 Pro Channel 3.
}}

{{FAQItem
|question = 2. Most mixer XLR outputs are line‑level, which is a poor match for the L1 Pro’s mic‑level XLR inputs
|answer =
This mismatch can cause:
* Input clipping
* Harsh distortion
* Unpredictable behavior
}}

{{FAQItem
|question = 3. You can sometimes “make it work,” but it’s not ideal
|answer =
You might avoid clipping by:
* Turning down the mixer output
* Turning down the L1 Pro channel volume

However:
* Lower mixer output reduces signal‑to‑noise ratio (more hiss)
* Very low L1 Pro channel settings give almost no usable range
* Volume may jump from too quiet → too loud with tiny adjustments
}}

{{FAQItem
|question = 4. Channel 3 avoids all of these issues
|answer =
Channel 3 is designed for line‑level sources and provides:
* Proper level matching
** Lower input sensitivity (less likely to clip/distort)
** Full +24 dBu headroom
* Predictable behavior
** No ToneMatch presets
** No Reverb
** No DSP gain steps

This is why the recommended method is:
;<big>'''Mixer Mono Out → {{XLRTRS}} → L1 Pro Channel 3'''</big>
}}
}}
}}
{{FAQItem
|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 of the Channel 3 {{14TRS}} input is lower than the {{14TRS}} inputs on Channels 1 and 2.
This allows Channel 3 to handle '''line‑level''' sources with less risk of clipping.

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.

For more information, see [[Mixer to L1 Pro]].

=== 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.

For more details, see [[L1 Pro Daisy Chain]].

{{FAQItem
|question = Excessive Hiss
|answer=
{{TroubleShootingItem
|problem = Hiss with nothing connected to the L1 Pro inputs when I turn up the volume
|symptoms = Hiss with nothing connected, volume turned up
|causes = with no input, turning up the volume amplifies noise
|solutions= turn down the volume or mute any unused channels
