QUICK GUIDE
1. Be sure that your mixer is turned off and that all level controls* are turned all the way down.
* STEREO OUT Master fader, Channel faders, GROUP 1-2 faders, GAIN controls, etc.
Note: Set the equalizer and the PAN controls to their ▼ positions.
2. Turn off any other external devices, and then connect microphones, instruments and speakers.
Note: Connect electric guitars and basses through an intermediary device such as a direct box, preamp, or
amp simulator. Connecting these instruments directly to the professional audio mixer may result in
degraded sound and noise.
3. To avoid damage to your speakers, power up the devices in the following order: Peripheral devices→
professional audio mixer→power amps or powered speakers). Reverse this order when turning power
off.
NOTE: If you are using condenser microphones that require phantom power, turn the professional audio
mixer's phantom power switch on before turning on the power to the power amp or powered speakers.
4. Adjust the channel GAIN controls so that the corresponding PEAK indicators flash briefly on the
highest peak levels.
Note: Turn the channel PFL switch on if you want to get an accurate reading of the incoming signal level
using the level meter. Adjust the GAIN controls so that the level meter indication occasionally rises above
the "▼" (0) level.
Note that PHONES jacks output pre-fader signals from all channels with their PFL switches set to the ON
position so that these signals can be monitored via the headphones.
5. Set the STEREO OUT Master fader to the "0" position.
6. Set the Channel faders to create the desired initial balance, then adjust the overall volume using the
STEREO OUT Master fader.
NOTE: * To use the level meter to view the level being applied to the STEREO L/R buses, set the PFL
switch off (
)
* If the PEAK indicator lights frequently, lower the Channel faders a little to avoid distortion
