•Monitor output signal on the level meter
Single Press
Mute/unmute a channel. Mute is indicated by the mute LED.Press and Hold (3 seconds)
④ Selected Channel LED
Illuminates when a channel is selected.
⑤ Signal Strength LED (sig/clip)
Indicates audio signal strength for each channel:
• Green = Normal
• Amber = Strong
• Red = Clipping (to eliminate clipping, attenuate the signal level at the audio source)
⑥ Mute LED
Illuminates red when the channel output is muted (hold its channel select button for 3 seconds). A muted channel is still routed to the HEADPHONE jack for
monitoring or troubleshooting.
⑦ Input Level Selector
Set the selected channel to line- or aux-level to match the input signal.
⑧ Output Level Selector
Set the selected channel to an output level that matches the connecting device:
• line: +4 dBu
• aux: -10 dBV
• mic: -30 dBV
⑨ Output Attenuation Control
Use the up/down buttons to attenuate the channel output from 0 dB (no attenuation) to -24 dB in 1 dB increments, and from -24 to -78 in 3 dB increments.
⑩ Level Meter
Displays a selected channel's audio level in dBFS. It is good practice to use -18 dBFS on the output meter as an approximation of 0 VU on an analog meter.
⑪ Hardware Status LEDs
Indicate the status of the hardware:
