DDL-500 - Eventide Audio

A Digital Delay Line with an Analog Soul

The DDL-500 features up to 10 seconds of pristine delay at a 192 kHz sample rate and a unique design that strictly limits the amount of digital circuitry to the bare minimum. Soft saturation clipping, low pass filter, feedback, insert loop, relay bypass, and +20 dB boost are all analog.
Delay time can be varied smoothly either manually or by connecting an LFO to the remote input allowing short delays to be used for comb filter and flanging effects. The DDL-500 is also capable of extremely long delays (up to 160 seconds at a 12 kHz sample rate) allowing long passages to be captured for looping.
From short delays for double tracking, to ridiculously long delays for experimentation, to creating swept delay and tape echo class effects, the DDL-500 brings it all in a single 500 series slot.
