5.Control Elements

This chapter describes the various control elements of your mixing console. Each control and switch is explained in full detail.

5.1 Mono channels

+48 V

This control LED lights up as long as the phantom power is switched on. The switch is found on the rear panel of the unit.

Trim

The TRIM control adjusts the input gain.

Be sure to set this control fully counter-clockwisebefore you connect or disconnect a signal source to or from one of the inputs.

The dial offers 2 different value ranges. The first value range between 0 and +60 refers to the microphone input, indicating the degree of amplification applied to the input's signal. The second value range between -20 and +40 dB refers to the amplification of the line input. When centered (at 12 o'clock), the line signals are neither boosted nor cut.

80 Hz

Press the 80 Hz switch to activate the high-pass filter which blends out low-frequency noise (-3 dB at 80 Hz, 18 dB/octave).

Equalization

The mono input channels provide 4-band equalization with 2 semi-parametric mids. You can boost or cut the bands up to 15 dB. When in center position (0 dB), the equalizer has a flat response.

HIGH

The high-frequency range is processed with a shelving filter above 12 kHz.

HIGH MID

A semi-parametric peak filter processes the upper mid range between 400 Hz and 8 kHz. The FRE control selects the frequency which is boosted or cut by using the HIGH MID control.

LOW MID

A second semi-parametric peak filter processes the upper mid range.

The FREQ control selects the frequency which is boosted or cut by using the HIGH MID control.

LOW

The low-frequency range is processed with a shelving filter below 80 Hz.

EQ

The EQ push-button switch activates the equalizer. Toggle the EQ to give you a quick comparison between unprocessed and processed signal.

5.1.1 FX, MON, AUX send paths

The send paths FX, MON and AUX allow you to tap the signals of one or more channels and route them to other outputs. This way you can create individual mixes for effects (FX) and musicians performing on stage (MON). Using the FX/MON/ AUX send outputs, the mix is fed to the stage loudspeakers and effects units.

FX 1 and FX 2

The FX buses are used as send paths to external effects units. The signal is usually tapped after the channel fader and therefore is affected by the position of the channel fader.

The FX control adjusts the volume level of the channel signal to the effects unit.

PRE

Press the PRE switch to change the routing of both effects paths from "post-fader" to "pre-fader." This way the volume level of

the effects signal is not affected by the channel fader.

Both the FX control on the channel and the corresponding Master FX SEND control need to be fully turned up as well.

Connect the FX Send output to the input of the effects unit. The effects signal is routed back through the FX Returns found in the master section.

Monitor 1 and 2:

The monitor buses are used as send paths to stage monitors. The monitor sends are hardwired pre-fader. This means the volume level of the monitor mix is not affected when using the channel fader.

The MON control adjusts the volume level of the channel signal in the monitor buses.

AUX

The aux buses are used as additional, flexible send paths for various applications. The AUX control adjusts the volume level of the channel signal in the aux buses.

The sum of all aux signals is determined by the corresponding AUX SEND control found in the main section. The signals can be routed from the corresponding AUX SEND outputs. Both the aux send paths can be amplified up to +15 dB and are pre-fader and post-fader switchable in the main section.

Pre-fader or post-fader:

For most applications using external effects signals, the aux send path should be switched to post-fader so that the effects volume level in a channel is affected by the position of the channel fader. If not, the effects signal would be audible even with a pulled down fader. For monitoring applications, the aux send paths are usually switched to pre-fader and therefore are not affected by the channel fader. To offer you the utmost flexibility, the FX buses can be switched to pre-fader in each channel. What's more, you may switch the AUX buses in the main section between pre-fader and post-fader. This gives you a maximum of 6 pre-fader buses or, alternatively, 4 post-fader plus 2 pre-fader buses.
