Alesis Microverb IV Manual

Microverb (C4) General Description
The Alesis
MicroVerb IV is the
latest in the line of
popular effects
processors of the micro
series. Similar in
performance to the
MicroVerb, the
NanoVerb is a scaled
down version.
Combining the well
known power of Alesis
custom processing with
small size and
affordability, the
MicroVerb IV (Product
Code C4) and NanoVerb
(Product Code NV) are
based largely on the
design of the MidiVerb
IV. The MidiVerb IV
Figure 1
custom chip set, along
with the latest ADC and DAC technology help make the C4 and NV two of the most
powerful signal processors in their price ranges. Particularly in the NV the use of surface
mount technology helps push the envelope of size and weight verses performance.
Reference designators for the C4 are taken from the Rev. C schematic. Reference
designators for the NV are taken from the Rev. B schematic and are denoted by brackets
{} when components are functionally similar to the C4. Note that for both of these units
there are several different main PCB revisions. There are no functional differences
between these revisions. However, it should be noted that older PCB revisions will have
some wire jumpers that later rev.s incorporated into the PCBs. Figure 1 shows the
simplified block diagram of the C4. As the NanoVerb is even simpler, there is no need to
simplify it beyond the schematic.
