Resurrecting a long sought-after and famed compression unit used on many Beatles records and heard on countless recordings, the RS124 Compressor with Stepped I/O from Chandler Limited is a smooth, powerful, mono compressor, powered by real analog tubes and sporting reimagined functions for the modern studio environment. Modeling three distinct versions of the legendary Abbey Road compressor, the potent RS124 rack unit harnesses the sound and character of the original, but also provides loads of new functions, including the ability to stereo link for twice the compression, selectable output impedance (classic 200 ohms or modern 600 ohms), and a new, unique SuperFuse mode that greatly enhances your output signal with a livelier sound that will seem to jump right out of your monitors.

The RS124 sports attack control (with settings for each modeled revision), recovery/release control in 11 positions, a hold setting for keeping the source signal compressed to the most recently processed peak, and full input and output attenuation. With transformer-balanced XLR input and output jacks, a circuit rebalancing utility for those rare instances when the tubes get out of alignment, and a low-noise, internal PSU, this rack unit is ready to handle any potential scenario and start producing award-winning recordings right out of the box.

First designed in 1960 by Abbey Road Head of Technical Bill Livy, Deputy Head Len Page, and seasoned EMI Audio Designer Mike Bachelor, the Abbey Road RS124 compressor is one of the most desired and mysterious pieces of recording gear ever developed. Born out of the insufficient Altec 436Bs acquired by EMI in the late 1950s for Abbey Road, the RS124 compressor is most closely associated with recordings made by The Beatles at Abbey Road Studios. Present on virtually every Beatles session, the RS124 left its remarkable signature across most of the catalog.

The RS124's undeniably smooth character and ability to tame transients without muffling the sound at steep compression levels quickly became popular with Abbey Road Studios engineers and widely used throughout the now historic studio, for tracking, buss compression, mixing, and mastering.

The new RS124 Compressor has been used on countless recordings. While the original has long been a mainstay in the Abbey Road Studios, Chandler's recreation has been used by:
