Featuring 15-bit equivalent digital companding PCM, the Roland SDE-2500 digital delay allows dynamic range of wider than 96dB, and total harmonic distortion of better than 0.05%.
The Roland SDE-2500 has memory capacity that retains 64 different settings of delay effects which can be easily edited by using the controls and switches on the front panel. MIDI Program Change message (0 to 127) serves to call the delay effect variations in memory.
The maximum delay time if the SDE-2500 is 750ms and the External CV Input Jack allows remote control by the control voltage externally fed into the unit. There are other useful remote-control jacks on the Roland SDE-2500 such as Playmate that allows setting the delay time in real time, Delay On/Off, Hold and Preset Shift Jacks.
The SDE-2500 can retain the delay setting you have made in its memory for later retrieval. When the delay setting in memory is recalled however, the four main controls on the front panel will not necessarily reflect the actual settings stored as they are not motorised.
The delay setting when stored on the Roland SDE-2500 includes delay time, delay output level, feedback level, Modulation (Rate and Depth), and on/off of delay range, delay phase and delay filter switches.
