Notes:

While you adjust the input signal levels for channels 1, 2, and 3, ei- ther use the headphones or turn up the receiver/amplifier’s volume to a comfortable listening level (not necessarily the final usable level).

Do not play a quiet portion of mu- sic while you adjust the volume levels, otherwise the volume lev- els for channels 1, 2, and 3 will be overdriven during the loud por- tions of the music.

Important: Write down or remem- ber the CH 1 volume level slide control’s setting for the selected audio source, so each time you want to mix that source you can slide the CH 1 volume level slide control to the correct setting.

Note: If it was necessary to set the CH 1 volume level slide control all the way to 10 in order to get a reading of up to 0 on the VU meter, then slide CH 1 down to about 8 and rotate MASTER clock- wise until you get the reading of 0 on the VU meters.
