Controls & Connections

(6) EQUALIZER CONTROLS

All channels are fitted with a three-band EQ - HIGH, MID, and LOW. All three bands have up to 15 dB of cut and boost, with a center detent for OFF. The frequency response is flat when all three EQ knobs are in the center detent position. The HIGH and LOW shelving controls have their frequencies fixed at 10KHz and 80Hz respectively. The MID control has a peaking response at 2KHz. The channel EQ is a valuable feature of the mixer as it allows the user to control the tonal characteristics of each channel separately. For example, boosting the LOW can fatten the sound, add warmth to vocals, or extra punch to bass, drums and synths; the MID control can be used to define the midrange or bring out the vocals; and adjusting the HIGH control can provide a crisp sounding high end. Another very important, yet often overlooked technique is to use the EQ to subtract from the mix. Cutting the HIGH control can reduce unwanted sibilance, hiss, cymbals,

or high frequency feedback, while attenuating the MID or LOW can also eliminate feedback or clear up a muddy sounding mix. Cutting the HIGH and LOW, then pushing up the Channel Level Control(6) is equivalent to mid range boost!

[Note: Always check the channel’s Peak LED Indicator(5) after altering the amount of equalization].

The key to successful equalization is to avoid excess. Too much equalization on the input channels will result in a mix that is smeared together with nothing specifically defined. During rehearsals, experiment with the equalizer controls on various instruments, vocals and combinations of these mixed together to become familiar with various equalizer settings.

(7) AUX SEND CONTROL

This control adjusts the level of signal sent to the Aux Send(23) output. The channel Aux Send control is mono, post-EQ, and post-Level control meaning the signal level sent to the Aux bus will also be affected by the Channel Level(9) setting.

(8) PAN

The channel Pan positions the output of the channel in the left/right stereo field of the Main mix. Its constant-power design ensures there are no level discrepancies whether a signal is hard- panned, center-stage, or somewhere in-between. For channels 3⁄4 and 5⁄6 this acts as a balance control.

(9) CHANNEL LEVEL

This controls the volume of the channel signal sent to the Main bus.

(10) PRE-FADER TO RECORD SWITCH

Enabling this switch will route the input signal of the channel to the Record Outputs(30). The signal will be post-EQ and pre channel level control.

(11) CHANNEL 3/4 & 5/6 STEREO INPUTS

These 1⁄4” and RCA unbalanced inputs are designed to accept line level signals such as those common to CD/tape players, keyboards, direct outputs and home stereo or DJ equipment.

The 1⁄4” inputs can also be used as standard mono line inputs by plugging into the L input only. This signal will be routed equally to the Pan control and the left and right outputs in the same way as the standard line input channels.

For each channel there are separate A and B stereo inputs. Using both sets of inputs simultaneously can cause some level issues, which may require the volume of the preceding equipment to be adjusted. The “A” 1/4” inputs are always enabled. To utilize the “B” RCA inputs, the B Enable Switch(12) must be depressed. This allows the user to switch on the B input source instantaneously.

(12) B ENABLE SWITCH

Depressing this switch will turn on the B Inputs of channels 3/4 and 5/6.
