THE BUS+ Quickstart Guide

Thank you for purchasing
THE BUS+THE BUS+ takes the classic SSL Bus Compressor and enriches it with an abundance of new sonic options, control and flexibility
to match the needs of today's mixing and mastering engineers. If that wasn't enough, THE BUS+ also features a completely newand 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.
LOW THD, F/B, 4K MODE
3 different sonic options for shaping the overall sound of thecompressor. LOW THD provides a cleaner bottom-end, F/B offers amore 'relaxed' style of compression and 4K MODE adds character andvariable 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.

VARIABLE SIDECHAIN HIGHPASS FILTER
Control the amount of low-end
triggering the sidechain with thevariable S/C HPF.

MIX
Easily dial in parallelcompression.
HONE THE TIME CONSTANTS
More ATTACK and RELEASE options thanever before. Try .05s RELEASE on drums or
AUTO 2 on a mix.

THE BUS+ is an all-analogue processor with a twist. The stepped pots on THE BUS+ are read by an on-board microcontroller, 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 digitallycontrolled analogue approach gives THE BUS+ immunity from pot tolerances, helping to eliminate stereo mis-match andensuring precise control. This approach is extended to the front panel buttons: electronic switches are driven from themicro-controller, providing clean and reliable switching that you can rely upon for many years to come.

MAKE-UP
Push and hold to switch theMAKE-UP control between coarse(1dB) and fine (0.5 dB) steps.

LF/HF GAIN
A make-up gain for the LF band ofthe D-EQ. Push the knob to add theclassic G-Series overshoot/undershootresonance around the frequency point(green indicator on). If the unit is in a
STEREO mode, this knob becomes HF

SUPPLY
Simply connect the IEC to amains power socket and use
the rocker switch to power on/off.

SIDECHAIN SEND
Allows for creative duplication of the input signal - could be used
to feed an external processing unit such as an EQ, returning theprocessed signal into EXT S/C IN. Or, it could be used to access theencoded Mid and Side signals, when using the unit in Mid Side mode.
