BANDWIDTH – is used to adjust the width of the bell filter, sometimes called a “Q”
control. A narrow width (CCW) is useful when you want to target a small range of
frequencies whereas a wider shape (CW) is used for more broader equalization.
TILT EQ SECTION
This control is used to adjust the overall spectrum of the sound you are processing.
Turning the control clockwise results in a boost in high frequencies and attenuation of
the low frequencies. Turning the control counter clockwise results in the opposite
effect where the lows are boosted and the highs attenuated. All this action occurs
around a centre frequency of 700Hz with a gentle slope of around 4dB per octave
(Baxandall style). The Tilt control is always in circuit, as long as the Channel is switched
IN.
OUTPUT
Finally, the output level of the Channel can be trimmed using the knob and it has a +/-
8dB range. The Channel IN push button switch below the OUTPUT knob is used to
switch the entire Zodiak channel in or out. When switched out, the input XLR is
connected directly to the output XLR via a relay (bypass). On power up the, the unit is
always bypassed for a few seconds.
PEAK
This red led will light when the internal operating level has r22dB peak level
indicating a possible clipping situation. It monitors the Zodiak signal path at several
points, and may light up if the Bell section has a lot of boost dialed in, even when not
switched in.
POWER ON
This switches the mains power to the Zodiak on and off. A red bezel indicator tells you
when you have it switched on correctly. The bypass relays are engaged for a few
seconds at power up.
