Alesis Nanoverb

18 bit digital effects processor (1996)



OVERVIEW On the front panel, in all and for all, five rotary potentiometers. The first three are for controlling the input, output and mix level used to adjust the balance between the incoming direct signal and the effects of the NanoVerb)-  while the last two ones allow you to choose and adjust the desired effect program. Finally, two LEDs display the power-up of the device and the signal input level. 
PSU is a AC-AC 9V (not DC!)

CONNECTION  the connection is made via two unbalanced 6.35 mono jack inputs and outputs. It is therefore possible to use it as well in mono as in stereo. A last jack on the rear panel allows you to connect a foot switch (optional) to activate or deactivate the output effects (bypass). No midi sockets, so no remote edit nor save banks.


Effects and edit

PRESET  sixteen programs which can be selected by turning the rotary selector. These effects are distributed as follows: ten reverbs (three Concert Hall, three Real Room, three Plate Reverb and one Non Linear), a delay, a flange, a chorus, a Leslie-type rotation effect and two combined chorus / reverb effects.

EDIT  Quite basic: each program has its own configuration which can be modified using the "Adjust" button e.g you can adjust the delay up to 1270 ms in 10 millisecond steps, control the depth of the chorus or the fall of a reverb.
