CHANDLER LIMITED TG12411 Channel - TG Channel MKII Channel Strip
The Chandler Limited TG12411 channel, formerly known as the TG Channel MKII, is a recreation of several classic circuits - combining Wade Goeke's design of the TG2 pre amp section with an equalizer that was redesigned from a circuit used in the TG12410 Transfer Console, the mastering counterpart to the original "Beatles desks."

The active portions of the unit use the same discrete amplifiers and transformers as in the TG1 Limiter and TG2 pre amp. The TG12411's passive equalizer EQ is an all inductor design offering sweet high frequencies, large inductor based lows, and a very high "Q" mid cut section. Its sound is very comparable to Pultec and Lang program EQs. A simple description would be a TG Pultec with a TG pre amp thrown in.

All TG units require and function on the PSU-1, Chandler Limited power supply. The PSU-1 has an internal switch for setting voltage to 120V or 220V (115V/230V). For more information please call us at (319) 885-4200.

NOTE: As of late 2016, the TG Channel MKII was renamed the TG12411; there has been no modification to the MKII circuit.

GC Audio – Gyraf Audio GY 4.5 Inherit Cartridge
GC Audio is proud to introduce a new preamp that extends the GC Audio cartridges family - based on a, now classic, design by Jakob Erland, founder of Gyraf Audio and designer of many high-end studio gears like the G9 preamplifier or the G22 compressor.

Jakob Erland is universally recognized as one of the leading experts in tube hardware design. He is also very popular in the DIY community where he provides free help. The GY 4.5 Inherit cartridge is, as its name implies, a single channel of the famous Gyraf Audio Gyratec 9 preamp. Faithful to the original in every detail.

GC Audio GY 4.5 is a genuine tube preamplifier: Coming with two ECC82 running on high voltage, no solidstate component in the signal path, input/output balanced by high-end Lundahl transformers. The goal with this design is to achieve everything from a completely clean to a possibly very colorful sound imprint. All under the total control of the user. The most important aspect of this circuit is its very slow transition to overload - it has a sweet spot that seems to last for ages.

We recommend it e.g. for vocals, where by raising gain and lowering output volume, you can get a nice dense analog saturation without overloading your converters. This cartridge is a real creative tool.

The proprietary Inherit format keeps the sensitive part of the electronic design in a one-piece machined cartridge that acts as a Faraday cage to offer optimal electromagnetic shielding performance.

Chandler Limited REDD 47 - Tube PreAmp
Chandler Limited’s REDD.47 microphone pre-amplifier is a recreation of the original valve line amplifiers used in Abbey Road Studios’ heralded and rare EMI REDD.51 recording consoles circa 1959-1968.

Designed as a central component to the EMI REDD.51 recording console, the original REDD.47 line amplifier was used to amplify virtually every stage of the audio path (mic inputs, line inputs, echo sends and monitors).
The REDD.47 lent its unmistakably punchy, aggressive character to music recorded at Abbey Road Studios between 1964 and 1968, including many tracks by The Beatles.

The Chandler Limited REDD.47 pre-amp offers many additional benefits to the original design including increased gain, allowing a range of tonal options from pristine clean sound to classic rich, saturated tone with up to 2% harmonic distortion before clipping. The Chandler Limited REDD.47 pre-amp easily reproduces the distortions heard on The Beatles’ ‘Revolution.’

Chandler Limited’s REDD.47 tube microphone pre-amplifier delivers the legendary sound of Abbey Road Studios’ ‘Holy Grail’ pre-amp, with extra features to meet today’s recording studio standards.
