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 eight-segment LED level meter located just to the
left of the MASTER VOLUME control displays the audio level on the main signal bus.
Mute L, Mute R, and Mono Switches
These switches set the stereo headphone outputs to one of three operating modes. (This affects only the
headphone outputs and occurs post (after) the balance/mix, and level control sections.)
1) All Switches Out = Stereo
2) Mute L In & Mute R Out & Mono In = Right Channel Only in Mono
3) Mute R In & Mute L Out & Mono In = Left Channel Only in Mono
Stereo Aux In Jack
These stereo TRS jacks provide a means of inserting a direct stereo signal into an individual headphone
channel. When a plug is inserted into an AUX INPUT jack the BALANCE control for that particular channel
changes function to become a mix control adjusting the mix between the signal coming into that channels
stereo AUX IN and the main signal bus.
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. Two identical output jacks are provided on the rear panel for
each channel as well.
