CONTROLS and JACKS
Front Panel
FIGURE 1 - Master Input and Channel One
Direct In Jack
The 1/4-inch TRS (Tip, Ring, Sleeve) jack on the front panel provides a stereo unbalanced input which when
used will override the rear panel balanced inputs. This input is useful for when you want to temporarily insert a
different main input signal from what is connected to the rear inputs, or simply make an unbalanced TRS style
connection to another headphone output source.
Master Volume Control
This control adjusts the level of the main signal bus. The audio level on the main signal bus is displayed by
the eight-segment LED level meter located just to the left of the MASTER VOLUME control.
Mono L and Mono R Switches
These switches set the stereo headphone outputs to one of four operating modes. (This affects only the
headphone outputs and occurs post (after) the mixing, level, and tone control sections.)
1) Both Switches Out = Stereo
2) Mono L In & Mono R Out = Mono Left Channel Only
3) Mono R In & Mono L Out = Mono Right Channel Only
4) Mono L In & Mono R In = Mono Left & Right Channels Together
Out Jack
This stereo TRS 1/4-inch jack provides a connection for each of six output channels to stereo headphones or
to additional headphone distribution amplifiers. A second identical output jack is provided on the rear panel for
each channel as well.
