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. 5. DJ Mic Talkover Switch. When engaged this mutes your music sources from channels 1-4. Releasing it brings you immediately back to full source level. It is very useful for announcements. 6. Treble, Middle and Bass Controls fine tune the tone of your music through the sound system.
