System information

Description
The AV dsp amp is a class D amp for use in powered speaker systems. As an active
“ ”
speaker controller, a AV dsp amp can form the basis of a powerful active two-way
monitor. In stereo mode one AV dsp amp will power an active master / passive
slave pair. Finally, the module may also be used as a one-way 140W amplifier.
All signal processing, including volume control, is done using the on-board
DSP (digital signal processor).
Figure 1 shows the block diagram of the amplifier. When two modules are used,
the second unit slaves to the first unit (master) through a link cable. The link
cable (a stereo mini jack cable) carries both the right audio channel and
control data. This way, both units respond to the master’s control panel.
A PC controls the AV dsp amp through the USB port. This connection is used to
upload the configuration and filter settings. An optional board permits use of
the USB link for audio as well as an SPDIF link. In digital mode, master/slave
linking is done through the SPDIF in/out connections instead of the mini jack
cable.
