Manual revision: 1.0 (may 2014)

Thank you for buying this IGS Audio product.

Please read the information provided below very carefully before using your IGS unit.

Unpacking

Your S-TYPE 00 has been carefully and meticulously tested and inspected before dispatch.

Please check for any signs of transit damage. If any signs of mishandling are found please

notify the carrier and your dealer immediately.

Your S-TYPE 00 packing should contain an S-TYPE 00 with IGS Audio tag (packed in ESD

bag) and this manual with the Warranty and RoHS/CE/WEEE Declaration attached.

Compatibility and Power

The S-TYPE 00 module is designed to be installed into an API™ 00 Series compatible rack

and cannot function stand alone, requiring the power source supplied by the rack system.

The current consumption of the S-TYPE 00 is rated at 1 0 miliamperes per slot. It is a stereo

module, so it takes up two rack spaces. Please check with the rack manufacturer that the

design can meet the S-TYPE 00 requirements.

Mounting

WARNING! Never plug or unplug any 00 series module with the power supply switched on.

You may destroy your unit permanently!

The dimensions of all IGS Audio 00 series modules are compatible with API standard. When

plugging your new unit to the 00-series rack, no unnecessary force is needed. However,

please be careful and do not rush while pushing the unit into the rack sockets, to avoid

damaging of the connectors and/or the PCBs of either the unit or the rack.

After the unit is placed in the rack, use the screws provided with your 00-series rack unit to

make sure that the unit is safely placed.

When removing the unit from the rack, unscrew the front panel from the rack, and use your

fingers to pull it out gently. Do not use any sharp objects (i.e. knives or screwdrivers) to prize it.

IGS AUDIO S-TYPE 500 – stereo VCA compressor

The S-Type is a typical VCA compressor well known as the core of the legendary British sound.

The heart of the compressor is the THAT chip instead of the now unavailable DBX. The

analogue path is balanced with ultra-fast op-amps. This is the source of completely transparent

sound. A minimal level of noise allows the device to be used in recording classical music,

including long range recording. The main new feature of the S-Type is the Sidechain HPF

regulation. This allows the user to select the lowest frequencies which will not be compressed

and more precisely control the bass and dynamics of the mix. Overall the S-Type is a very

creative device.

Typical usage:

- Great summing and mastering compressor

- Beat compressor for external drum machines

- Drum compressor for live drums

- Can be used to compress single stereo instruments (pads, leads)

- Mono compression, using external side-chain

The S-Type is a precision dynamic range controller intended for use in the most demanding

professional audio applications. RMS detection, high headroom input circuits and output drivers,

give the S-Type its own sonic excellence.

Block diagram

VU METER Big VU meter showing the amount of gain reduction.

THRESHOLD Above this level of the input signal the compression will occur.

Use it to control the amount of compression.

SIDECHAIN

HPF

This switch applies the high pass filtering to the sidechain

circuit. It allows to avoid the „pumping” sound of ie. the kick

drum – low frequencies will not trigger the compressor.

RATIO Allows to adjust the compressor ratio. From 2:1 (soft

compression) up to 10:1.

ATTACK Time delay between the appearance of the signal and the

compressor reaction.

RELEASE Time delay between the disappearance of the signal and the

compressor reaction.

MODE You can either bypass the whole unit or use London or NewYork

style of compression.

MIX Wet/dry mix knob. Allows the parallel compression to be used.

Work Modes (London vs New York)

The S-TYPE 00 compressor is equipped with two sidechain circuit settings. The first one called

'London' (selectable with the LONDON – BY – NEW YORK switch) is a stereo mode. Two

channels of the unit are being summed up and used to control both VCA stages.

In 'New York' mode only the left channel is being used to control both VCA stages. That allows

you to use the S-TYPE 00 as a mono side-chain compressor where the signal at the left input

controls the amount of the compression applied to the right channel.

Troubleshooting

My unit doesn't power up (POWER LED is dark):

–Check if the power supply is turned on

My unit doesn't light up (LED bar is dark):

–Make sure that the signal source is properly connected to the module

–Adjust the threshold level (using the THRESHOLD knob); insufficient input level might

cause that the signal level is below the compressor threshold level

–Make sure that the mode switch is in LONDON or NEW YORK position

The signal plays thru but there is no change in signal when i turn the knobs:

–Make sure that the mode switch is in LONDON or NEW YORK position

–Turn the MIX knob clockwise (WET) – it will allow the compressed signal to be more

audible

No signal plays thru the unit, regardless the settings at the front panel:

–Make sure that the signal source is properly connected to the module
