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

Does the Channel ToneMatch Setting (MIC/INST/OFF) change the input gain?

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

This 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.
