The balanced XLR jacks for INPUT 1–8 provide +48V phantom power for use by condenser
mics; you can switch this on/off independently for each channel.
Your equipment may be damaged if you connect or disconnect a condenser mic with phantom
power turned on. You must turn phantom power off before connecting condenser mics.
2 MONITOR LEVEL knob
This knob sets the volume level of the signal being sent from the MONITOR
OUT L/R jacks.
3PAD buttons
The pad will reduce the input level by 26 dB. The pad is on when the switch is
pressed in. You can extend the adjustable range of the TRIM knob by turning
the pad on when using a line input.
Leave the pad switched off for a low-output device such as a mic or guitar.
4 TRIM knobs
These knobs adjust the input level. The LED located at the upper right of each
knob will light to indicate the following conditions.
Lit green: an input signal is present
Lit orange: nominal input level
Lit red: input overload
Use the TRIM knob to make adjustments so that this indicator does not light
red when the input level from the connected device reaches its loudest point.
The TRIM knob has a range of +14 to –34 dBu when PAD is on, or –12 to –60
dBu when PAD is off.
The markings around the knob indicate the input level.
The input level will depend on the instrument or performance, but the
approximate ranges are as follows.
–60 – –40 dBu: mic input
–30 dBu: guitar, bass guitar
–10 dBu: consumer audio devices such as a CD player
+4 dBu: keyboards or studio equipment
If the TRIM knob is raised when nothing is connected to the input, hum or noise may re-
sult. Keep the trim knob at its lowest setting when the channel is not in use.
