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.

Chandler Limited TG12345 MKIV EQ - 500 series modular EQ
The Chandler Limited TG12345 MKIV equalizer is a handmade, fully discrete, mono, single space module, designed for the 500 Series format.

The TG12345 MKIV EQ for 500 Series, inherits from Chandler Limited’s TG Microphone Cassette and flagship TG12345 Curve Bender, and draws its heritage from the input and group channel equalizers found on historic EMI TG12345 recording consoles of the late ‘60s and early ‘70s.

The TG12345 MKIV control-set includes: presence and bass bands, with continuous boost/cut, and true bypass.

The presence band is switchable, featuring eight frequencies and an out position. The first seven frequencies are bell type, and the eighth is a shelf at 10 kHz.

The bass band is a shelving type, featuring two frequency options, 90 or 150 Hz.

MOTHER WAI 2950 (wire and iron) is a 3-Band, completely discrete class A inductor based ,500 series eq. In a way, we recreated the legendary W295, an EQ famous for its magically beautiful “high shelf” and real vintage vibe, the secret weapon of many producers over the past decades. Input and output are balanced by Mother's custom high class transformers. A special challenge was the output transformer, which with the integrated LPF at 20khz is a really critical element to not lose the well-known sonic character and the choice ultimately fell on the 50% Nickel core. Also, the impedance of the input transformer, (which in the geniune unit was relatively low) was incrased to today's standards and all this resulted in an extended low freq response and a slightly “excited” sound, if we compare it with the Siemens module. The PCB board is full of NOS BSX46 Phillips transistors, and as much as possible Siemens NOS film capacitors. All controls are stepped.

How it sounds?
Completely magical, huge, but still focused low end and incredibly sweet highs, creamy
mid range, very characteristic for an inductor based circuit.

Where can it be used?
Anywhere where you actually want character and sweetness.

ACME Audio Motown EQ - 7-band graphic equalizer
In the continuing effort to faithfully recreate classic Motown audio products for today’s recording studios, Acme Audio is proud to announce the highly anticipated release of the Motown EQ. An absolute legend among audio engineers and producers, only 48 of the original Motown EQs were ever produced and it’s considered one of Chief Engineer Mike McLean's pinnacle achievements at Motown Studios. With its transformer balance audio path and gain makeup amplifier section, this 7-band graphic equalizer was a vast improvement to the products that were commercially available in the Motown era.   Acme Audio had the honor of spending several weeks with the late Mike McLean reverse engineering an original Motown EQ and had his ongoing guidance to faithfully recreate and reintroduce this classic piece of equipment to the recording world.   

No components were compromised in this reproduction… every inductor, capacitor, and transformer was either sourced from original manufacturers or painstakingly recreated to match the performance and sonic quality of the original Motown EQ.  In essence, this is the closest you will ever come to owning this essential piece of recording history.

Purple Audio TAV is a ten-band inductor-based graphic EQ. Designed to work in standard “500″ racks designed by Ed Anderson for Purple Audio.

An illuminated pushbutton for relay true bypass (green) allows for easy comparison with unprocessed source material. A Tricolor LED meters the signal. The frequency response is +/- 0.25dB from 15Hz to 25kHz, and -3dB at 60kHz.A new take on the console graphic, with ten easy to use bands. Each band uses a high quality inductor and carefully selected caps to set the center frequency. At full boost and full cut the bands are narrow enough to still be useful individually, but at lower settings the bands widen out for more gentle shaping. Even at full boost and cut, the filters are shaped to be musical and useful.

With specialized input and output transformers, the TAV has plenty of headroom, even at full boost. The entire circuit is discrete, with no electrolytic capacitors in the signal path, and no servo amps. With only two active stages, the current draw is low enough to work in any rack, and leave plenty of juice for other modules. The Tav uses one KDJ3 op-amp and one KDJ4 op-amp.
