Can I use XLR cables from my mixer into Channels 1 or 2?

You can, and it might work, but it often leads to problems.

1. Some mixers can output mic‑level on XLR — most cannot If your mixer allows switching its XLR outputs from Line to Mic, then it may work. But this is uncommon. Using XLR → ¼″ (6.3 mm) Tip‑Ring‑Sleeve into Channel 3 is far more reliable.

2. Most mixer XLR outputs are line‑level, which is a poor match for the L1 Pro’s mic‑level XLR inputs This mismatch can cause:

• Input clipping
• Harsh distortion
• Unpredictable behavior

3. You can sometimes “make it work,” but it’s not ideal You might avoid clipping by:

• Turning down the mixer output
• Turning down the L1 Pro channel volume

However:

• Lowering the mixer output reduces signal‑to‑noise ratio (more hiss)
• Turning the L1 Pro channel knob very low gives almost no usable range
• Volume may jump from too quiet → too loud with tiny adjustments

4. Channel 3 avoids all of these issues Channel 3 is designed for line‑level sources and provides:

• Proper level matching
• No ToneMatch presets
• No Reverb
• No DSP gain steps
• Lower input sensitivity (less likely to clip/distort)
• Full +24 dBu headroom
• Predictable behavior

This is why the recommended method is: Mixer mono out → XLR‑to‑Tip‑Ring‑Sleeve → L1 Pro Channel 3

Is the Channel ToneMatch Setting (MIC/INST/OFF) like a MIC/LINE switch on other active loudspeakers
Does it change the input gain?

No. This is NOT like a MIC/LINE selector found on many other powered loudspeakers.

The Channel ToneMatch Setting (MIC/INST/OFF) affects only the ToneMatch Preset applied to the input. It does not affect input sensitivity or gain applied to the signal.

Channel ToneMatch Button: Select the ToneMatch preset for an individual channel. Use MIC for microphones and INST for acoustic guitar. The corresponding LED will illuminate white while selected.
