RECALLABILITY & MASTERING-GRADE PRECISION
THE BUS+ is an all-analogue processor with a twist. The stepped pots on THE BUS+ are read by an on-board micro-
controller, that in turn controls the analogue circuitry. You may be familiar with the term 'digitally-controlled analogue'...
this is what THE BUS+ is. Not only are the stepped pots on THE BUS+ easy to recall but in general, the digitally-
controlled analogue approach gives THE BUS+ immunity from pot tolerances, helping to eliminate stereo mis-match and
ensuring precise control. This approach is extended to the front panel buttons: electronic switches are driven from the
micro-controller, providing clean and reliable switching that you can rely upon for many years to come.
EXTERNAL
SIDECHAIN
Trigger the
sidechain for the Bus
Compressor and/or
D-EQ externally.
MAKE-UP
Push and hold to switch the
MAKE-UP control between coarse
(1dB) and ne (0.5 dB) steps.
POST D-EQ
The Bus Compressor can be
positioned before or after the D-EQ
for processing order exibility.
LF/HF GAIN
A make-up gain for the LF band of
the D-EQ. Push the knob to add the
classic G-Series overshoot/undershoot
resonance around the frequency point
(green indicator on). If the unit is in a
STEREO mode, this knob becomes HF
GAIN. G/HF indicator will now be red.
D-EQ
2-band Dynamic EQ with LF and HF bands. Push the
knob to engage and then turn left to start compressing
or right to start expanding. Tri-colour LEDs provide
feedback on the amount of processing being applied.
Push and hold the knob and then use the +/- buttons
in the centre of the unit to adjust the Frequency and
Range settings for that band.
D-EQ
HF > FAST and LF > FAST
buttons provide different
sidechain attack/release settings,
or press and hold for AUTO
modes. HF Bell allows the High
Frequency band to switch from a
Shelf to a Bell lter.
SIDECHAIN SEND
Allows for creative duplication of the input signal - could be used
to feed an external processing unit such as an EQ, returning the
processed signal into EXT S/C IN. Or, it could be used to access the
encoded Mid and Side signals, when using the unit in Mid Side mode.
AUTO-RANGING POWER
SUPPLY
Simply connect the IEC to a
mains power socket and use
the rocker switch to power on/
off.
