Channel Auxlliary Sends
Each Scepter input channel features four auxiliary send controls. These
controls feed auxiliary masters A, B, C and D and allow the user to create four
additional mixes of the signal sources fed to the mixer. These mixes are generally
used as feeds to external FX devices, as
mixes to an onstage monitor
system, or as a cue mix for performers headphones in recording situations.
Aux A and B are normally PRE-EQ feeds to the Aux A and B mixes. These
mixes are unaffected by channel EQ settings and fader position and may be used
as feeds to an on-stage monitoring system. It should be noted that whilst these
mixes are not affected by changes in the EQ settings, they ARE affected by
changes made at the input gain control, and changes made there may require that
a proportional change be made at the aux send.
Aux C and D are normally POST-FADER feeds to the Aux C and D mixes.
Their operation is dependent on the level of the channel fader and will change
proportionally with fader movements and will be cut off when the mute switch is
activated. For this reason, these mixes are normally used to feed external FX
devices.
SCEPTER Series mixers have been wired in this configuration at manufacture.
However provision has been made within the mixer which allow the user to choose
the point in the channel circuit from which the aux level control derives its source.

Equalizer
The channel EQ allows you to alter the tone and harmonic balance of the
signal in the channel. You can filter out unwanted high frequency noise (hiss), or
low frequency noise (rumble), and compensate for deficiencies in older
microphones or problems with your acoustic environment.
High Frequency Equalizer
This control either boosts or cuts the high frequency content of the signal
source by up to 16dB at and above, having progressively less effect at
frequencies below This is known as a shelving type equalizer. At its centre
position the control has a flat response and no effect on the high frequency content.
Mid Frequency Select
This control tunes the mid centre frequency between and
