Description

Design features
Audio path quality
The entire audio path of the SOC-20 optical compressor is made using Buzz Audio's proprietary Class A discrete transistor BE41 amplifiers with a Lundahl LL1517 transformer at the output. A special low impedance power supply design is used to enhance the sound quality of the amplifiers by providing very stiff power rails. This overall combination produces a unique sound character with full bass and a vibrant top end void of any midrange harshness. Whilst the SOC-20 is not a clone of any vintage units, it's design is inspired by the use of the LA2 and LA3 by it's designer Tim Farrant.

Mid-side processing power
Not only can the SOC-20 be used in dual mono or stereo mode, Buzz Audio has also incorporated a Mid-Side (or sum and difference) encoder and decoder. When set to MS mode, the stereo input is divided into signals that are common to left and right (called the mid) and signals that are not (called the side). The divided signals are sent to each channel of the SOC-20 then recombined at the output thereby allowing you to adjust the dynamics and width of the stereo image. This process has application on a wide range of stereo sounds including the mix buss and electronic music sub mixes. Check out the audio samples to see how powerful this process can be.

Side chain flexibility
At the flick of a switch, a high pass filter reduces the compressor sensitivity to low frequencies for more bass punch when used on program material. We have also included a fully balanced side chain insert point so you can add additional equalisation to the compressor characteristic or "key" the compressor with another source to create those pumping effects found in modern music styles. The side chain monitor function allows you to hear what is returning into the insert point and also monitors the mid or side signal when the compressor is used in MS mode.

Control genius
The unique differential side chain circuit of the Buzz Audio SOC-20 splits the audio into positive and negative waveform and processes it separately to obtain a differential drive into our custom BE45 electro-optical attenuator. There are 5 compressor attack settings and 6 release settings that cover a wide range of response possibilities. In addition, our intelligent auto modes allow for true "set and forget" operation. The 5 "soft knee" ratio settings allow for gentle to strong levelling, with the selected ratio only actually acheived at 10dB of gain reduction. The SOC-20 opto compressor is extremely muscical - ideal for vocal and instrument recording plus it is equally at home on the stereo buss to glue your mixes together - a truly multi-purpose studio compressor now available in a mastering version.

Controls and functions
DRIVE - variable pot that sets the amount of compression.
OUTPUT dB - variable pot that adds gain at the output to correct for lost level.
ATTACK - rotary switch with 1mS, 10mS, 25mS, 50mS selections and the excellent AUTO mode.
RATIO - rotary switch with 2:1, 4:1, 6:1, 10:1 and 20:1 selections - all soft knee characteristic.
RELEASE - rotary switch with 100mS, 200mS, 400mS, 800mS 1600mS selections and our superb AUTO mode.
BYPASS - hard wire unit bypass to compare compressed and uncompressed signals.
METER - switches the VU meter between input/output levels or amount of compression.
S.C. HPF - inserts a 170Hz high pass filter into the side chain for added bass punch.
S.C. INSERT - engage the external side chain insert point and monitor the side chain signal.
LINK A/B - joins the side chain of each channel for stereo operation with "soft" tracking.
There is also a locking toggle to select STEREO or MID-SIDE mode and a handy POWER on/off switch.

Buzz Audio SOC 1.1 The use of Light Dependent Resistors (LDR) as the control element of an audio compressor was pioneered in the 1960's and we are all aware of the value placed on those famous vintage "LA" units. The Buzz Audio SOC-1.1 was designed not to copy, but to take that signature and improve on it by offering the user more control. With 4 ratio settings, 3 attack options and 6 release times, the SOC-1.1 puts you in command of the dynamics rather than dealing with set parameters.

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.

The Smart Research 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.

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.

Chandler Limited Zener Limiter - TG 12413 Zener Limiter
The EMI TG12413 Zener Limiter is the ultimate TG Limiter issued in celebration of the 75th birthday of Abbey Road Studios. The Zener Limiter was conceived by Chandler Limited designer Wade Goeke and is based on the vintage EMI circuits used to record The Beatles and Pink Floyd. This newest EMI Limiter continues the tradition of EMI Limiters started in 1956 with the RS114 tube limiter, and continued with the RS168 Zener Limiter in 1966, part of the TG12345 console channel in 1968 and TG12413 in 1974. The newest version borrows from the RS168 Zener Limiter and TG12345 console strip to make a new fully featured and flexible unit for modern use. It is interesting to note that the TG Limiter was originally designed to replace both the Fairchild 660 (Limit Mode) and the Altec 436 / RS124 (Comp 1 Mode)

The main reason for Zener Limiter reissue was to add features and flexibility to the powerful and vintage sounding TG limiter circuits. To that end Wade has added many new controls including switchable input impedance for hard of soft driving of the unit, 11 position attack, 21 position release, side chain filtering, and Comp1, Comp2, and Limit settings.

A simple Limiter from the rich past of EMI and Abbey Road has now come full circle into a modern powerhouse suitable for recording, mixing, and mastering. The rest is NEW Chandler Limited/EMI/Abbey Road history....

Buzz Audio ZODIAK - Dual channel tilt and filter equalizer
Equalize a different way with the Zodiak's four complimentary tone control sections creating a powerful new sound shaping tool.

The "Tilt-n-Filter" EQ idea was delivered to us by Zak Cohen, owner of the Woodshop Recording Studio, and it is based on a series of plug-ins Zak would routinely set up to equalize music tracks recorded direct into his DAW. The Zodiak reproduces this concept with the same series of eq elements - but in the analogue domain so it can used ahead of the DAW input. The main element of the design is the Baxandall style Tilt eq circuit (originally found on the Quad 44 hifi preamplifer from the 1970's). The concept of a tilt EQ is not new, but with the addition of a fully parametric midrange band and high and low cut filters, the Zodiak caters for a wide range of applications that would otherwise require multiple processors. What's more - the Zodiak is available with three signal path options to suit your taste and budget.

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.

Buzz Audio SOC 1.1 The use of Light Dependent Resistors (LDR) as the control element of an audio compressor was pioneered in the 1960's and we are all aware of the value placed on those famous vintage "LA" units. The Buzz Audio SOC-1.1 was designed not to copy, but to take that signature and improve on it by offering the user more control. With 4 ratio settings, 3 attack options and 6 release times, the SOC-1.1 puts you in command of the dynamics rather than dealing with set parameters.

Buzz Audio REQ-2.2 resonance mastering equalizer is a high-end stereo, four band inductor based, parametric mastering and recording equalizer, that operates and sounds like no other.

The resonance factor
The REQ-2.2 equalizer utilises parallel resonant circuits in a clever configuration whereby the bandwidth (Q) of the circuit can be adjusted like an active filter, but without any complex relay switching. The inductor/capacitor resonant "tank" eq circuit runs at a low internal signal level which avoids any inductor saturation effects. The overall result is the sound of real choke based filters with a big open sound, but without the limitation of only a few - or no bandwidth selections as found on traditional choke eq's.
