Optional Modules
The Digital Video Machine always comes equipped with all of the standard outputs
and control interfaces shown at the beginning of the Controls and Indicators
section. However, the DVM also has a variety of options that can be installed at the
factory to increase its capabilities.
Amplifier Option (/A)
Be sure to pay
attention to the
speaker polarity while
making connections.
This version of the Digital Video Machine provides two discrete channels of amplified
audio for powering speakers. Each channel is rated at 20 Watts of power at 8Ω. This
built-in amplifier features protection that is designed to shutdown the amplifier in the
event that the output is overloaded.
IMPORTANT NOTE: Do not bridge the speaker outputs!
Professional Audio Option (/B)
The balanced output
level is +4dBu. The
S/PDIF output is a
standard IEC-958
signal containing
either Stereo (2-
channel) or Dolby
Digital AC3 (5.1
Channel) audio.
When this option is installed, the DVM will supply balanced line-level outputs and a
digital audio output. The balanced outputs are provided on combination ¼ inch XLR
jacks, and the digital audio output is on an RCA jack.
