ALM-100 10 Channel Loss of Audio Alarm
A System 1000 Module
The ALM-110 Loss of Audio Alarm Module monitors ten audio
sources simultaneously, providing LED indicators on the front edge of
the module, and alarm logic outputs at the rear connector of the card
frame. For sophisticated computer driven monitoring, it furnishes a
logic output for each audio input as well as an OR'ed output for simple
alarm systems. Alternate output pull down transistors allow relays to be
driven. Average signal level threshold is also adjustable from
-10 dBu to +8 dBu per channel.
Features
- 10 red LED alarm indicators
- 10 discrete logic outputs (per channel)
- 1 daisy chain OR'ed output
- OV (GND) = safe state, +12 V = alarm state
- 2-30 second adjustable off warning delay
- Variable level threshold
Price: $390.00 Product has been discontinued.
ALM-110 Application
System signal flow diagnostics may be greatly simplified using the
ALM-110. Perhaps one of the best uses of the module is to monitor the
input and output of every piece of equipment in a critical signal path,
such as an On-Air chain. Then, by monitoring the digital outputs of the
module with a computer program written in, say, Visual Basic, you may be
able to quickly see where a loss of audio occurred, such as with an
incorrect patch insertion. Adding graphical features to the program,
showing a map of the signal path with a flashing break point, can
greatly enhance diagnostics and reduce lost air time.
