Rolls RD320 User manual

RD320 Digital Room Delay
The RD320 is a single input, single output digital room delay for speaker
distance delay, or time alignement. The unit has two modes of operation
selected by a shorting jumper behind the security cover on the front panel.
It allows the delay range to be either 5 - 320 milliseconds, or 40 - 1280
microseconds. The delay time is easily set, as are the input and output level
settings, all controlled behind the security cover on the front panel.
The RD320 is a clean, virtually transparent delay designed and manufac-
tured for years of reliable use.
FEATURES:
 Two delay increment modes - 5 to 320 ms, or 40 to 1280 µs
