Soundcraft EPM12 [18/36] Stereo input channels

STEREO INPUT CHANNELS

1 INPUTS STEREO 1/2

These inputs accept 3-pole ‘A’ gauge (TRS) jacks. Use these inputs for sources such as

keyboards, drum machines, synths, tape machines or processing units. The inputs are

BALANCED for low noise and top quality from professional equipment, but you can use

UNBALANCED sources by wiring up the jacks as shown in the “Wiring it Up” section

earlier in this manual, although you should then keep cable lengths as short as possible.

Mono sources may be used by plugging into the left jack only.

2 GAIN

The GAIN control sets the level of the channel signal.

3 EQUALISER

HF EQ

Turn to the right to boost high (treble) frequencies, adding crispness to percussion from

drum machines, synths and electronic instruments. Turn to the left to cut these

frequencies, reducing hiss or excessive brilliance. Set the knob in the centre-detented

position when not required. The control has a shelving response giving 15dB of boost or

cut at 12kHz.

LF EQ

Turn to the right to boost low (bass) frequencies, adding extra punch to synths, guitars

and drums. Turn to the left to reduce hum, boominess or improve a mushy sound. Set

the knob to the centre-detented position when not required. The control has a shelving

response giving 15dB of boost or cut at 60Hz.

4 AUX SENDS

These are used to set up a separate mixes for FOLDBACK, EFFECTS or recording, and

the combination of each Aux Send is mixed to the respective Aux Output at the rear of

the mixer. For Effects it is useful for the signal to fade up and down with the fader (this

is called POST-FADE), but for Foldback or Monitor feeds it is important for the send to

be independent of the fader (this is called PRE-FADE).

AUX SENDS 1 and 2 are both globally switchable between pre and post-fade (see master

section on page 20/21). The send pots are fed with a mono sum of the L & R signals.

5 BALANCE

This control sets the amount of the channel signal feeding the Left and Right MIX buses,

allowing you to balance the source in the stereo image. When the control is turned fully

right or left you feed only that side of the signal to the mix. Unity gain is provided by the

control in the centre-detented position.

6 MUTE

All outputs from the channel are enabled when the MUTE switch is released and muted

when the switch is down.
