c) 10-band Equalizer
There's a separate 10-band equalizer available for the left and right channels. The equalizer is activated by
pressing the button at the right, under the power switch. 10 frequencies can be adjusted by +/-12dB to adapt the
final mix to the environment or your own taste.
Between the 2 equalizers sits a Dual LED meter that indicates the levels of the left and right master channels.
In the upper right corner there's a BNC lamp adapter that allows you to connect a 12V/3W lamp to light the panel.
Under it you find the power switch. Set it to 'I' to turn the mixing panel on. The LED next to the power switch lights
up. To turn off the unit, set the power switch to '0'.
d) Master & Effects
1. Master section: allows you to regulate
the balance and the level (slide switch)
of the final mix, and whether it's in
mono or stereo. Stereo means the left &
right signal can differ, depending on the
source signal. In mono mode, the left &
right signal is the same (sum of original
left & right).
2. Zone section: is a secondary output
section, to feed a second amplifier for
remote speakers or DJ booth monitors.
It features the same controls as the
master section.
3. Echo section: features an on/off switch
(the echo is on when the LED is lit), a
volume control, a repeat control that
lets you control the time period during
which the echo is repeated, and a delay
control to regulate the time between the
original signal and the echo.
4. Effect switch: allows for exterior sound effects to be used; see back panel below.
5. Headphones section: consists of a ¼" (6.35mm) jack, a volume control, and a slide switch to enable you to
switch between the cue and main channel, or to listen to both together.
6. Effects section: features six programmed special sound effects to create a unique mix, with a speed control to
adjust the pitch of the effect, and a volume control to determine the volume of the effect in the mix. Press the
button of the effect you want, hold it to generate sound, and release it to stop.
