Channel Controls

Front Panel

1HIGH EQ

This High EQ shelving type of active tone control varies the treble frequency (±15 dB

at 12 kHz) and is designed to remove noise or add brilliance to the signal, depend- 1 ing on the quality of the source.

	2 MID EQ	2
	Mid EQ is a band pass (peak/notch) type of active tone control that varies the mid-	2

	range frequencies (±15 dB at 450 Hz).

3LOW EQ

A shelving type of active tone control that varies the bass frequency levels (±15 dB at 70 Hz). Low EQ adds depth to thin-sounding signals or cleans up muddy ones. As with any EQ‚ use sparingly. Too much of this EQ can give you a booming bottom end.

4MON (monitor)

This control varies the level of each channel signal (pre-EQ) that is added to the monitor mix.

5EFX

The EFX control varies the level into the digital effects processor bus‚ adjusting signal level from the individual channel to the digital processor. It is post gain and will be affected by the gain control.

6SIGNAL/CLIPPING INDICATOR

These LEDs illuminate green when a signal is present and red when clipping occurs. If clipping occurs‚ turn the gain (7) down. If the channel clips when turning the Level control up only slightly‚ try engaging the Pad switch (8).

7GAIN

This control sets the signal level sent to the main mix.

8PAD

Pad attenuates the input signal by -25 dB. If you notice distortion from a particular channel or if the channel becomes loud very quickly‚ try engaging this switch. In ad- dition to increasing the dynamic range‚ the channel input can now accommodate a higher input level before clipping occurs, which may be helpful when close-mic’ing a loud guitar amp or drum kit, for example.

9LINE INPUT

These line inputs are 1/4” balanced TRS inputs. The tip is the positive input which may also be used for unbalanced inputs. A pad switch is provided to attenuate strong signals present at this input. Note: The Mic input and the Line input cannot be used simultaneously within the same channel.

10MIC INPUT

These mic inputs are XLR balanced‚ low-impedance channel inputs optimized for a microphone or other low-impedance source. Pin 2 is the positive input. Due to the wide range of gain adjustment‚ signal levels as high as +10 dBV (2.45 V RMS) can be accommodated with the pad switch engaged. When the phantom power is enabled‚ this connector has +48 V on pins 2 and 3 with pin 1 as the ground reference.
