3 PHONO/LINE switch. Channels 1 to 4 are the

stereo ‘MUSIC’ channels. In the up position the

switch selects the PHONO input, indicated by the

green led. This input provides standard RIAA

equalisation for high quality magnetic cartridge

turntables. When pressed, LINE is selected,

indicated by the led changing colour to red. Use

this to select non-RIAA or alternative stereo music

sources.

4 LEVEL control. Adjusts the input sensitivity

of the channel to match the connected source to

the console 0dB operating level. This provides a

20dB range with continuous adjustment for line

level signals from –10dBu to +10dBu. Use the Cue

system to correctly set the level.

Reduce LEVEL if the red +10 led flashes.

5 MUSIC EQ. Stereo Channels 1 to 4 feature a

unique four band equaliser providing infinite

attenuation of high and low frequencies and -30dB

attenuation of mid frequencies. This provides the

DJ with effective equalisation to creatively alter and

shape the sound during live performance rather

than simply correct source problems. This type of

equaliser is known as ‘asymmetric’ because the

amount of boost and cut is not the same. Boost is

restricted to a safe +6dB to highlight selected

sounds while preventing system overload through

heavy use. Cut on the other hand, is used to

completely suck out affected frequencies allowing

two or more tracks to be mixed together without

vocals or bass lines clashing.

HI Turn this control clockwise to boost and

anticlockwise to cut the high (treble) frequencies.

This has a shelving response when turned

clockwise with all frequencies above the 2.5kHz

turning point affected. When turned fully

anticlockwise the response changes to a low pass

filter (12dB/Oct) with all frequencies above the cut-

off point being progressively attenuated. Use HI

boost to brighten up the sound by adding sparkle,

and cut to eliminate all HF content.

MID 1 Turn clockwise to boost and anticlockwise to

cut the higher mid frequencies. This has a bell

shaped peak/dip response that has maximum effect

at 2kHz. Frequencies in this range can be boosted

by 6dB or attenuated by 30dB. The “Q” or

frequency bandwidth also alters from a high Q

(narrow bandwidth) on boost to a low Q wide

bandwidth when cutting. This prevents

accumulated gain when all EQ controls are fully

clockwise.

MID 2 This is similar to MID 1 but affects the lower

mid frequencies centred at 350Hz. Boosting can

enhance the warmth of the sound while cutting can

reduce the unpleasant resonant or boomy effects.

LO This is similar to the HI control but affects the

low (bass) frequencies below the 250Hz turning

point. . When turned fully anticlockwise the

response changes to a high pass filter (12dB/Oct)

with all frequencies below the cut-off point being

progressively attenuated. Use LO boost to

accentuate the bass lines/beats, and cut to

eliminate all LF content.

6 FILTER assign switch. Toggle this switch to

route the channel signal through either of the two

VCF FILTER sections. Selecting the switch in the

central ‘OFF’ position bypasses both the VCF

FILTER sections. Note: Routing the channels to the

filters with the filter ON can produce audible clicks;

route the channels to either filter with the filter

turned off to prevent this.

7 XFADE assign switch. Toggle this switch to

route the channel signal to either side of the

crossfader. Selecting the switch in the central ‘OFF’

position routes the signal direct to the mix outputs.

8 CUE switch. Press this switch to listen to the

pre-fader channel signal in the headphones and to

display its signal on the main meters. This does not

affect the house mix or booth speakers and lets you

audition the signal to cue a track before adding it to

the mix. Cue is typically pre-EQ for music channels

so that you do not lose your reference when beat

mixing, regardless of the EQ effect, but can be

selected to be post EQ by selecting the POST EQ

switch in the master section. The CUE light-pipe

illuminates so that you can see at a glance which

channel is cued.

Selecting one cue will automatically cancel the

previous cue. Multiple cues can be selected by

pressing two or more together, but make sure all

cues are OFF first.

9 Channel meter. A 9 led meter bar always

shows the presence of the pre-fader channel signal.

Adjust the LEVEL control for normal music

averaging 0dB with loudest moments reaching +6.

Reduce the level if the red +10 led flashes.

10 Channel fader. A 60mm linear or rotary

stereo VCA fader adjusts the signal level from off to

the normal top position. This allows smooth fade

ins and a visual indication of its contribution to the

mix. The fader does not affect the pre-fade Aux

sends.
