Mic Preamps
Chandler Limited’s REDD.47 Mic Amplifier recreates the valve line amplifiers of Abbey Road’s rare EMI REDD.51 consoles, from around 1959 to 1968. The original REDD.47 was a central component of the console and amplified almost every stage of the audio path: mic and line inputs, echo sends and monitors.Its punchy, aggressive character marked everything recorded in Studio Two between 1964 and 1968, including many Beatles tracks. Chandler’s version adds more gain and ranges from pristine clean sound to rich, saturated tone with up to 2% harmonic distortion before clipping, enough to reproduce the distortion heard on “Revolution”.
The Germanium Pre Amp/DI is an entirely new design by Wade Goeke for Chandler Limited, using classic germanium transistors in an all class A, transformer-balanced circuit. Germanium transistors were the basis of the earliest transistor designs by Neve (1053, 1055, 1057), EMI (TG12345 MKI), Telefunken and Fairchild, and anyone who has worked with those units knows their special sound.The circuit runs on +40 V with high current and has huge headroom, up to +34 before clipping. The sound is warm and smooth, and it settles into the mix without fighting the other tracks. Chandler’s custom-wound transformers combine the best parts of favourite St Ives and Gardners transformers.
The TG Channel MKII, now named TG12411 by Chandler Limited, combines two classic circuits: Wade Goeke’s TG2 preamp and an equalizer redesigned from the TG12410 Transfer Console, the mastering counterpart of the original “Beatles desks”. The renaming came with no change to the circuit.The active sections use the same discrete amplifiers and transformers as the TG1 Limiter and TG2. The passive EQ is an all-inductor design with sweet highs, large lows and a very narrow mid cut. Its sound compares closely with Pultec and Lang program EQs. Put simply, a “TG Pultec” with a TG preamp thrown in.
The REDD.47 began life as the microphone amplifier of EMI's REDD.51 console at Abbey Road, and its character — dense, forward, with a controlled aggression through the midrange — became one of the recognisable signatures of the recordings made on it. The Special Edition is not a cosmetic variation on the current REDD.47: Wade Goeke builds each unit around 53 vintage components collected over years, including Piher, ISKRA, Beyschlag and ERO/Roederstein resistors and Siemens, Wima and Mullard «tropical fish» capacitors — the same parts found inside original EMI equipment.What it adds over the standard REDD.47The front panel layout follows the logic of the original REDD console cassettes and carries the new lighted EMI sign. Beyond the aesthetics, this edition incorporates three sections taken directly from the REDD.51 console: Input Sensitivity, Line Input and Bass Lift with 10 dB of low-frequency boost. The signal path remains the core REDD.47 path — EF86 and E88CC valves, transformer-balanced input and output on custom wound transformers, +57 dB total gain with stepped Pre Amp Gain from 16 to 52 dB and Fine Gain of ±5 dB.
The Warm Audio WA-2MPX is a two-channel tube microphone preamp and an authentic reproduction of the vintage tape-machine tube preamp that helped give birth to rock ‘n’ roll. With 300 V of operating voltage, up to 90 dB of gain per channel and selectable tape saturation, it brings tape-era warmth and colour to vocals, instruments and mixes.During the golden era of tape recording, the original 351-style tube preamp became a studio staple, in the signal chain of hits by Elvis Presley, Bing Crosby, Les Paul, Nat King Cole and Roy Orbison, and of producers like Steve Albini. With premium components and a true-to-original circuit, the WA-2MPX reproduces all the analog tone of the original across two channels.
The Warm Audio WA-412 is a four-channel microphone preamp with instrument DI in a 1U rack, based on classic American console preamps. It is ideal when you need several channels of quality tone, for example to record drums or a full band, at an affordable price.This style of preamp is often called "the sound of Rock n' Roll" for its big, punchy low end and smooth, open top end. With fully discrete socketed 6-pin op-amps and custom-wound Altran USA input and output transformers, the WA-412 offers a price/performance ratio that impresses even seasoned engineers.Inspiration behind the WA-412Warm Audio founder Bryce Young always wanted more channels of high-end preamps in his studio, but his budget only allowed one or two, never enough to record a full band or drummer. The WA-412 was designed "for the people": multiple channels of world-class tone for professional and home studios, so signals are recorded well on the way in.More featuresThe WA-412 has all the features one would expect from this style of preamp, and more. Output Trim is available on every channel for precise control and creative gain structuring, and a Tone switch (transformer input impedance) on each channel lets you choose between a warm, punchy classic console tone or a more open and neutral sound.Better componentsEach channel uses a fully discrete socketed 6-pin op-amp that can be swapped with others. Discrete op-amps are known for high headroom and low distortion, and are a big part of the coveted sound of classic console preamps. All input and output transformers are made in the USA by Altran, developed with Warm Audio to extend the low-frequency response, using a vintage winding technique for a distinct, smooth, big character.
