The new Stereo Toolbox is designed to "offers a ‘first’ in the 500 series API Lunchbox format," according to SSA, with a stereo buss compressor capable of processing audio in either LEFT/RIGHT or MID/SIDE.

A stereo width control, sweepable from mono through stereo to extra wide, is available in all modes of operation independent of whether you’re processing in L/R or M/S.

The unit accepts balanced Left/Right stereo audio and is designed to deliver transformer balanced Left/Right stereo audio outputs at levels up to +28dBu.

The dual channel/stereo compressor is based on Safe Sound’s ‘dynamic tracking’ circuitry which is designed to allow the attack and release times to be dynamically modified by analogue processing which tracks the dynamic content of the audio material being processed (hence ‘dynamic tracking’).

Mid/Side processing is designed to allow you to work on the width, depth and dynamics of the stereo sound field during the latter stages of the mix.

The compressor has two separate sets of controls for drive (threshold), ratio and attack, which can be linked for stereo compression, used unlinked for dual mono, or in mid/side.


The unit features a sweepable high pass filter which can be selected to operate during L/R or M/S compression in the mono sidechain to control low frequency pumping, or it can be switched to operate in the SIDE audio chain to remove low end boom.


Cinemag steel-core output transformers are fitted as standard and may be ‘on-board’ selected to either transparent or high colour tones. This is achieved by altering the drive impedance to the transformer primary coils. Output levels of up to +28dBu are available
with ±15dB of adjustable gain make-up within the final drive amps.


The rotary controls feature 41 position dented potentiometers fitted with solid metal control knobs. LED Metering, covering L/R, M/S and gain reduction is provided.

Pricing & Availability
Compatible with the API 500 series modular format, the new ‘Stereo Toolbox’ is available now, priced at $1,299 from ZenPro Audio in the US. Also available in a number of other countries from Safe Sound Audio’s dealers and distributors.
