The Smart Research C2 The C2 compressor houses two independant mono compressors, or in STEREO mode, the left-hand controls operate both audio channels, with the right-hand controls not used, giving true Stereo operation. The C2M version has one set of controls and two audio channels for Stereo use, whilst the C2R is a dual channel remote expander for building up to 8 channel systems controlled from one C2M or C2.

The characteristic sound of this unit arises mostly from the fast response at the onset of compression, which when delayed to occur around the mid range attack settings (after 0.3 to 3 milliseconds) results in a window through which transients can still pass. When used accross a mix, or with any dynamic programme, this has the effect of adding 'punch', as the sidechain 'breathes' around these transients, while still controlling overall levels. CRUSH mode has been developed as an extension of this 'musicality', adding to and accentuating the factors involved in producing the character of the unit. CRUSH may sound surprising to those interested in more gentle applications, being capable of exaggerated compression effects, but in conjunction with the fast limit settings also introduced with this unit, it allows the C2 to be used for a much wider range of applications than the C1.

Also available with a parallel compression stage (Blend) check the Smart Research C2B

Buzz Audio SOC-M - Mastering optical compressor
A precision stereo optical compressor optimized for analogue mastering featuring a mid side matrix and a balanced side chain insert point.

The SOC-M is available with a grey (silver) or black face plate.

Smart Research C1t is the modified version of the venerable C1 you can find in most modern UK and West Coast recording studios. The C1t is upgraded with the following new features:

C1 Sidechain Modifications
These mods add a three position sidechain high pass filter switch to each channel, and a stereo, unbalanced external sidechain input connector on the rear panel. Using the switches to roll off low frequency signals feeding the sidechain can reduce compression slightly at low frequencies, but without effecting frequency response of the audio signal path. The external inputs can be used for various effects such as 'ducking' from a vocal or the overlap of 'a bass and a kick ... etc.

High Pass Filter switches
The upper toggle switch is for the left channel, and the lower switch for the right. The center position is off (no filter): up is 75Hz, or down is 150Hz high pass. The filters either work on the normal (internal) sidechain signal, or on an external signal if fed into the external jack input.

External Input
Added to rear panel. The stereo input connector is normalled to break the internal sidechain source when a jack is inserted.

The Buzz Audio DBC-20 is a new take on a vintage technique utilizing a gain reduction element of silicon diodes in a balanced bridge arrangement. The diode bridge is coupled via a "radio steel" laminated transformer of our own design. This element produces a desirable compression character that can best be described as tight, colourful and rich with harmonics. In the style of compressors from the 60's, the DBC-20 incorporates a self-adjusting ratio whereby the compression ratio is progressively increased with deepening gain reduction. This feature allows for the control of very dynamic signals (such as vocals) in a seamless fashion. The DBC does sound very vintage but does not carry the vintage price tag!

The DBC-20 is available with a grey (silver) or black face plate.

Relative channel linking! Channels can be linked/unlinked anytime! It is allowed to have different settings on both channels and still manage those in a relative way!
We can work on Mid-Side mix separately for each channel, but if we would like to change balance of whole track, it is enough to engage “parameter link” and both channels Make Up gain will be adjusted relatively keeping same amount of volume difference!

MID-SIDE operation mode ngBusComp supports mid-side opeartion, you can give your side channel diffferent compression settings then middle channel!

Chandler Limited TG1 Limiter - Dual EMI Abbey Road Compressor/Limiter
The Chandler Limited TG1 is a recreation of the classic EMI TG12413 Limiter used in custom EMI and Abbey Road recording and mastering consoles from the late 60's. The TG Limiter was originally designed to be like the Fairchild 660/670 which was loved by many EMI engineers, including Geoff Emerick, but ended up with a very special sound all its own. These rare pieces were never commercially available and only EMI owned studios had access to them. Our version has been remade from the original design information and circuit board drawings as provided by Abbey Road and EMI to ensure extreme authenticity!

TG1 Updates & Modifications: Harmonic Distortion Function
Now standard on all Abbey Road Special Edition TG-1's, this option allows bypassing of the compressor/limiter threshold but leaves all circuits in the signal path, turning the unit into a powerful Harmonic Distortion generator capable of kicking out up to 2% Total Harmonic Distortion. That's more than 2 times the amount of analog tape! And all with 100% discrete transformer balanced circuits. Adjust the input for amount of THD and the output to match level. Try running Distortion on one channel and hard limiting on the other. The ultimate in retro! This option is placed on the front panel of the unit with a toggle switch for each channel.
