1.INTRODUCTION
Congratulations on your purchase of a DMA series digital matrix amplier. The DMA’s modular expansion cards will
provide you with up to eight channels of audio matrixing and processing. A single DMA amplier offers eight-in, eight-out
support (or eight-in, four-out), and the entire unit can be controlled remotely through standard potentiometers and remote
controls. Internal processing is accomplished through a high quality 40-bit oating point processor, with internal signal
processors and matrix routing all handled with ease�
DMA digital matrix ampliers offer easy, effective means for injecting signal processors directly into your input and
output path, with clear, easy-to-use software both onboard and on your Windows computer .The software offers full
performance monitoring for each processor, giving real-time information on the load placed upon DSPs�
2. FEATURES

AUDIO OUTPUT
SPEAKER OUTPUTS
Every two output channels (one odd channel and the
next even channel) can be bridged into one channel,
through which, please note; that a bridged channel, has
twice more power as an unbridged channel, because the
bridged channel has two channels combined.)
To bridge channels, just wire the “+” pin of an odd
channel to the “+” pin of the next even channel. When
bridged, the “+” pin of the even channel; becomes the “-”
pin of the bridged new output.
OUTPUTS
Offering unamplied signal, OUTPUTS connectors can
be also connected as Balanced or Unbalanced AUX
output if wired to do so�
