H2 Audio Helios Channel
With the rise of home recording and hybrid recording methods we have created The Helios Channel, featuring the classic 0011 mic pre/EQ and the F760 compressor limiter, all in a rugged steel 2U 19” rack to give you the ultimate classic recording chain. The Helios channel also features the Acme Audio Motown DI’s custom input transformer for its DI input. This transformer is electronically switched directly to the 0011’s mic-in connector when activated by a selector switch on the front panel. Also featured is 48V phantom power, output fader control and Link/Ind switch which allows The Helios Channel to be operated as a channel strip or as independent units complete with separate input and output connectors on the rear of the unit. The Helios Channel is powered by the same external PSU as the 0011, and 8-channel rack and up to 4 units can be used off of one supply.

Chandler Limited TG Microphone Cassette - EMI / Abbey Road Channel Strip
The Chandler Limited TG Microphone Cassette is a full-featured mixing console channel strip, incorporating elements of the historic EMI/Abbey Road Studios TG12345 recording and mastering desks of the late ‘60s and ‘70s.

Chandler Limited’s critically acclaimed TG1 Limiter, TG2 Pre-Amp, and Curve Bender EQ, each known for their remarkable reproduction of the EMI TG sound, have been combined to form the ultimate TG Microphone Cassette reimagined to work in a modern recording studio context.

The Overstayer Modular Channel 8755DS is a stereo channel with filters, EQ, compression, and ​harmonics stages throughout, with sophisticated routing and a series parallel mixer matrix. High quality  components and circuitry are used throughout. Though the unit can get extreme, the design aesthetic is that of a console in that it is capable of handling and maintaining the fidelity of a full mix through the unit.

The Modular Channel is available in 2 versions, the 8755DM-LI which has instrument and line inputs, and the 8755DM which adds transformer coupled microphone inputs, pad, polarity, and phantom power.

Lindell Audio 18Xs MKII is a one channel transformer coupled Microphone Preamplifier, DI, Line Amplifier and Passive Pultec Equalizer. It’s an Class A design based upon our Hybrid amplifiers. (It can be upgraded with our Vintage OPA)

The Equalizer is our take on the magical classic Pultec design. It’s got 15db boost of the creamiest high end you’ve ever heard and the most punchy low end heard the 21th Century.

We have also incorporated our famous ”Mix Knob” from the 17X compressor. This means that you can parallel equalize your line input. This gives you more flexibility and a way of creating new tones….

Overstayer Imperial Channel Model 8776A module is self powered, self-contained channel strip that can be used on its own (no chassis required) or as part of a larger framework for recording and mixing.

The 8776A features mic, line and instrument inputs, as well as filters, 4 band EQ, FET limiting and controls to shape and exploit the harmonic character of the circuitry throughout. Modules can be mounted vertically in dual, quad or 10 space rack-mountable chassis* (5RU high). Audio connections via XLR and TRS connectors with access to several points in the signal path.  

*Modules and chassis are sold seperately - Also available in Pair with a Free frame and metallic front cover transport protection.

Buzz Audio ARC-1.1 advanced recording channel strip
An extremely flexible preamplifier, equalizer and compressor system for all sound recording applications.

Quite simply, there is no other recording channel strip on the planet that has the versatility of the ARC-1.1. What you have here is a mic/line preamp, parametric equalizer and compressor/limiter that can be used in conjuction as a recording channel or, accessed as completely separate elements. The ARC is not just one piece of kit but multiple pieces bundled into one chassis with a clever relay routing system so you can assign each element to the main signal path or to externally accessed I/O.

UnderTone Audio MPEQ-1 the amalgamation of the UTA EQ and the custom mic pre of the MPDI-4. It features the same flexible and musical Class A discrete circuitry, the uniquely powerful HP/LP filters, and an exciting new approach to a Class A mic pre.

You can use the equalizer and the mic pre separately or as a complete channel strip. The mic pre has a custom input transformer and a carefully chosen output transformer. Both are optimized to accentuate the most flattering sonic qualities inherent in audio transformers.

The unique mic pre design makes both of these transformers bypass-able. This offers users a choice between the detailed clarity of a Class-A transformer-less design or the vintage musicality of a dual transformer mic preamp.
