RoXdon Analog BBD ECHO Studio Analogue Delay Unit

RoXdon BBD-ECHO Studio Analogue Delay Unit

HANDBUILT IN ENGLAND

The RoXdon BBD-ECHO Analogue Delay is a 1970's sounding echo unit utilizing BBD (Bucket-Brigade Device) discrete-time analogue delay line technology, providing up to 600ms of delay. Less hard work than tape delays and with a sound all its own, this vintage effect quickly became a classic. The 19" rack unit has controls for Mix, Level, Delay, Repeat and output Gain. The front panel also features a Modulation section for Tape Echo emulation with Speed and Depth controls. The RoXdon BBD-ECHO has been designed to be used in the recording studio to interface with preamps, mixers and other units operating at line level.

Tape based delay units were often unstable and unreliable, so by the start of the 1970's, the BBD circuit was a viable alternative. Developed by Philips Research Laboratories, the BBD shuttles a stored analogue signal through a consecutive series of capacitors - like old fashioned Fire Brigade buckets, hence the name.
Signals passed through the BBD circuit were subject to misidentification of the signal frequency, introducing distortion or error (aliasing) which gave the effect its distinct sound character sought by many musicians.

The RoXdon BBD-ECHO features a steel 2U 19" rack mounted enclosure manufactured with vintage style knobs, dials, on/off switch and power-on lamp . The rear panel has a 9 volt DC socket for connection of the external power adapter (supplied) and 1/4" line input and output jack sockets for connection to a sound mixer or line level source.
