The Four-Band Equalizer:
The four-band equalizer, like the rest of the Aurora Sidecar,
is all discrete transistor Class A circuitry.
The equalizer is selected by pressing the red “EQ” button
at the bottom of the channel. With the pots in the center
detent position the gain should not change significantly
when the equalizer is selected or deselected.
Starting from the high frequency control at the top, there is
a three position switch that varies the boost and cut to
allow very fine tuning of the EQ. With the switch to the left
the variance is +/- 6dB and with it to the right the variance
is +/-16dB.
The high and low mid frequency controls underneath have
a three position switch that provides three alternatives of
“Q” (bandwidth). The mid controls in the widest “Q” can
have almost 20dB boost/cut.
The low frequency control is similar to the high frequency
in that two choices of boost/cut can be selected, +/-6dB and
+/-16dB. Note that there is considerable overlap in
frequency choices between the HF and LF and the two mid
frequency controls.
To select either high pass or low pass filter, the red “EQ”
button must be selected, then press either yellow or green
button to select the 18dB per octave filter required.
