MONITOR FADER:
Controls the overall level of the Monitor mix originating from the channel MONITOR controls. The
monitor signal is available on the rear panel of the console to feed an external power amplifier. In Split mode, both the
main PA mix & the monitor mix are mono. This mode of operation is perfect for small club or pub gigs where you need a
simple system.
PEAK LED: Indicates that the channel signal is too highand is in danger of clipping. If the peak LED flashes more then
very briefly on the loudest signal peaks, reduce the channel GAIN control setting until it flashes only on the loudest signal.
LISTEN SWITCH:
When a LISTEN button is down the signal overrides the source selected by the METER/PHONES
SELECT switch, allowing signals to the meters and heard via the PHONES output. When this button is down the PEAK LED
lights, and remains on, to show listen is selected.
L/R OR GROUP SWTICH:
Routing button to direct the channel signal either directly to the Left/Right Mix or via the
Group fader. This enables Group sounds (such as drum Mics) to be controlled in level by the Group fader rather than living
to adjust several channel faders simultaneously. If the Group facility is not required, this button might be used as a channel
mute. For Mute operation, the Group fader must be fully down.
CHANNEL FADER:
Controls the level of the channel signal fed either to the Group or Left/Right bus, depending on the
setting on the L-R/ GROUP button. These faders feature a special taper which gives far better control than a conventional
log taper around the most important center or “0dB” position.
MON: STEREO (MONO: STEREO) CHANNELS: The MON:STER (Mono Mic/stereo line) channel is similar to the
Mic/Line channel except that its accommodates stereo signal when working at line level. Additionally, it is equipped with
single Mic input which has it’s own gain control; the Mic signal is mixed with the stereo Line Inputs allowing both sets of
Inputs to be used. The overall level being controlled by the channel fader is in the usual way. Both the Mic & stereo line
inputs share the same channel EQ & AUX send settings. The Equalizer features three-fixed band (MF @ 2.5kHz) & the Pan
Control is replaced by a balance control. If a line level signal is fed into the Left input only, the channel will function as
mono channel with the balance control.
GRAPHIC EQUALIZERS : (Only for Platinum Basic MKI & MKIII) - The graphic equalizers provide seven bands of
precision tone control across the whole audio Spectrum. In normal operation, the upper Graphic Equalizer affects the left
output channel and the lower graphic the right, Though graphic may be used to produce Eq effects, in the context of PA,
They normally help to compensate for poor venue acoustics or to cut troublesome frequencies where feedback is a
problem. If the Graphic Equalizer is not required to correct venue problems, it may be assigned to the group bus allowing
equalization to be applied only to those signals that need it, For example, you might want to feed all your drum mics to the
Group, assign the Graphic Equalizer to group and use the equalizer to improve the sound of the drum kit. In SPLIT mode,
where the PA runs in mono (and with the Graphic Equalizer assigned to amp L-R, the upper equalizer looks after the main
PA mix and the lower one is assigned to the Foldback output. This is exceptionally useful as the close proximity of the stage
monitors to the performers can often aggravate feedback problems. Again, the Graphic Equalizers can be used to pull
back troublesome frequencies. As a role, Graphic Equalizers are used to cut rather than boost. Applying a significant
amount of boost to any part of the audio spectrum increases the risk of feedback at that frequency.
Graphic Fader: (50Hz, 150Hz, 330Hz, 1kHz, 2.5kHz, 5kHz & 10kHz) Each fader has a centre detent or click stop
to indicate the neutral (flat) setting. Each fader prints the frequency at which it operates. This is the centre point of a narrow
band of frequencies covered by the fader. Each band overlaps slightly with the next to provide total cover of the whole
audio spectrum. Up to 12dB of cut or boost can be applied although, under normal circumstances, only a fraction of this
range will be used. (See Graphics Assign)
GROUP FADER: Controls the overall level of any channels routed to the stereo Group. This is a valuable feature for
controlling sets of instruments or sounds such as drum mics or backing vocals.
Graphic Assign 1 Switch: When switch is released the Equaliaser gets assign to L-R (Master) output. When switch is
pressed the equaliser gets assign to Group Signal.
Graphic Assign 2 Switch:
When switch is released the Equaliaser gets assign to L-R (Master) output. When switch is
pressed the equaliser gets assign to Mono Output.
