Channel Input Gain/Trim/Attenuation Controls. These control the sensitivity of the inputs for Channels 1-4. Use these whenever a particular source causes overload of the preamp inputs. Use these with the PFL (pre-fader listen) monitor when cueing. Treble, Middle and Bass Controls fine tune the tone of your music through the sound system. Note that these are also available on the DJ Mic. Use the Pan Control to maximize the Left or Right side of your Source. S e n d button will send the individual channel signal to the send jack on the rear panel. This is used to route to an external effects unit. The signal comes back in from the effects unit through any line input channel you select and is then sent out to your amplifier through the Master Output jacks on the rear panel. The Input Faders are low-noise, low-impedance, highquality, smooth faders. These control individual source levels in the mix. Channel Cue Assign/PFL pushbuttons are used to route channel audio to the Monitor Section. The channel input faders do not control the C u e volume. When the Cue button is pushed you get Pre Fader Listen(PFL). In addition, when these buttons are depressed the third row of the LED meter (20) will display the signal level of that channel on a PFL basis. The level can be adjusted by using the G a i n contr ol(1). Channels 1 - 4 Input Toggle Switches select which source will be live to that channel based on what you have connected to the rear panel input section. When engaged this mutes your music sources from channels 1-4. [. . . ] Speaker cable must be 14-gauge minimum; 12- or 10-gauge is better. Connect your music sources on the rear of the unit. Up to 3 phono and 8 line sources (CD players, cassette decks, tuners, etc. ) can be connected. When connecting to an input with a phono/line option switch remember to set the switch accordingly.
