Modern features have been added to meet contemporary recording studio standards, such as increased gain that gives you a range of new tonal options, from pristine cleans to rich, classic saturation.

The workhorse line amp of the REDD.51

A critical component of the EMI REDD.51 console (REDD being an acronym for Abbey Road Studios’ in-house Record Engineering Development Department), the REDD.47 line amplifier was used in virtually every stage of the audio path, including the mic and line inputs, the echo sends, and the monitors. With its spunky, in-your-face sonics, the REDD.47 lent its unique character to all the music – including every Beatles track – recorded in Abbey Road Studio Two during its mid-’60s tour of duty.

Enjoy an expanded range of tonal options

Chandler Limited’s REDD.47 preamp gives you added benefits never offered by the original design, including an increased gain range that greatly expands your tonal options. Imagine being able to dial between immaculate cleans and classic tube saturation with up to 2 percent harmonic distortion before clipping! Think of the gnarly, distorted guitars in The Beatles’ “Revolution.” They were DI’d straight into the board; all that seething mad-dog bite is the REDD.47. And speaking of direct injection, Chandler Limited has thoughtfully included a DI input on the REDD.47 front panel.
