5.MIC (LOW Z) INPUT

XLR balanced low impedance channel input optimized for a microphone or other low impedance source. Pin 2 is the positive input. This connector has +15V phantom power supply on Pins 2 and 3 at all times (Pin 1 is the ground reference).

WARNING: BECAUSE THE LOW-Z INPUTS HAVE PHANTOM POWER, ONLY CONNECT MICROPHONES OR PRODUCTS WITH A BALANCED OUTPUT TO PREVENT DAMAGE. IF YOU ARE UNSURE, PLEASE CHECK THE PRODUCT’S OPERATING INSTRUCTIONS.

6.LINE (HIGH Z) INPUT

1/4" unbalanced input that accepts line level sources equipped with a 1/4" plug (TS). The two inputs (XLR and 1/4") cannot be used simultaneously.

7.LEVEL

Sets the level of the individual channel in the mix.

8.REVERB

Sets the level of the internal reverb for the channel and must be used in conjunction with the master reverb level. It is post gain and will be affected by the LEVEL (7) adjustment. The Reverb/Aux control also determines the level of signal sent to the Effects Output (14).

9.CONTOUR

A shelving type of active tone control that varies the treble frequency level ±15 dB at 10 kHz. It is designed to remove noise or to add brilliance to the signal, depending on the quality of the source.
