The Eventide DDL-500 is a 500 Series digital delay with, low-pass filter, saturation/clipping circuit, front panel insert loop, and +20dB boost. An LFO can also be connected to the front panel Remote input to alter delay time. At 192kHz sample rate, the max delay time is 10 seconds, and at the lo-fi 16kHz sample rate, the max delay time is 160 seconds which allows the DDL-500 to function as a looper.
