THE BUS+
Quickstart Guide
www.solidstatelogic.com

THE BUS+ takes the classic SSL Bus Compressor and enriches it with an abundance of new sonic options, control and exibility
to match the needs of today's mixing and mastering engineers. If that wasn't enough, THE BUS+ also features a completely new
and powerful 2-band Dynamic EQ (D-EQ), making it an incredibly versatile analogue processor. To download the in-depth user
guide, head to the SSL website.
Thank you for purchasing
BALANCED XLR I/O
Connect THE BUS+ as a
hardware insert across your
audio interface or analogue
desk.
MODE
Choose the mode of operation
for the compressor - Classic
Stereo, S/C Stereo, Dual
Mono or Mid Side.
VARIABLE SIDECHAIN HIGH
PASS FILTER
Control the amount of low-end
triggering the sidechain with the
variable S/C HPF.
LOW THD, F/B, 4K MODE
3 different sonic options for shaping the overall sound of the
compressor. LOW THD provides a cleaner bottom-end, F/B offers a
more 'relaxed' style of compression and 4K MODE adds character and
variable harmonic content.
MORE RATIO OPTIONS
Expanding on the classic RATIO settings, are
new options perfect for Mastering (1.3:1, 1.5:1)
and creative effects (-2.5, -1.5 and -0.5), as well
as all the classic mix bus ratios. HONE THE TIME CONSTANTS
More ATTACK and RELEASE options than
ever before. Try .05s RELEASE on drums or
AUTO 2 on a mix.
MIX
Easily dial in parallel
compression.
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.
EXTERNAL SIDECHAIN
INPUTS
Connect external sources
you would like to trigger the
sidechain from.

MODE
Choose the mode of operation
for the compressor - Classic
Stereo, S/C Stereo, Dual
Mono or Mid Side.
MOVING-COIL METER
Displays Gain Reduction
for the Bus Compressor or
Frequency/Range settings
when configuring the
D-EQ.
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.
