When using high output playback devices it may be necessary to select the -10dB pad or the -20dB pad (or both) to stop the input channel from overloading.

The locations of these pads are shown on page 15.

TRIM

The trim controls allow a +/-15dB trim range to be applied to each channel’s signal.

The optimum setting is at zero on the input LED level meter.

HI EQ

These controls adjust the high tone characteristics of the CH1 / CH2 inputs. At the 12 o’clock, centre position the high EQ will be flat (no cut or boost). As the control is moved anti-clockwise the high frequencies will be progressively cut until, at the fully anti-clockwise position the maximum high frequency cut will be applied (-85dB). As the control is moved clockwise from the centre position the high frequencies will be progressively boosted until, at the fully clockwise position, the maximum high frequency boost will be applied (+6dB@10kHz).

MID EQ

These controls adjust the mid tone characteristics of the CH1 / CH2 inputs. At the 12 o’clock, centre position the mid EQ will be flat (no cut or boost). As the control is moved anti-clockwise the mid frequencies will be progressively cut until, at the fully anti-clockwise position the maximum mid frequency cut will be applied (-85dB). As the control is moved clockwise from the centre position the mid frequencies will be progressively boosted until, at the fully clockwise position, the maximum mid frequency boost will be applied (+6dB@1kHz).

LOW EQ

These controls adjust the low tone characteristics of the CH1 / CH2 inputs. At the 12 o’clock, centre position the low EQ will be flat (no cut or boost). As the control is moved anti-clockwise the low frequencies will be progressively cut until, at the fully anti-clockwise position the maximum low frequency cut will be applied (-85dB). As the control is moved clockwise from the centre position the low frequencies will be progressively boosted until, at the fully clockwise position, the maximum low frequency boost will be applied (+6dB@100Hz).

CHANNEL VOLUME FADERS

These 60mm travel faders are digitally controlled by the DSP and are used to adjust the volume of CH1 and CH2.

PEAK LEVEL METER

These indicators show the signal level pre-channel faders and cover a range of -15 to +5. The indicators from -15 to -3 are coloured blue. Indicators -1 to +3 are white, whilst the +5 indicator is coloured red.

CHANNEL FADER CURVE CONTROL

The channel fader curve control is located on the front panel. The 3 switched fader characteristics are created and controlled by the DSP. The fader action may also be reversed via the [REV] switch.
