Custom Bench Test Jig For Trident 80B Console Input Modules, Works Well.
This is a bench test harness that we built for troubleshooting and testing Trident 80B I-O modules. It's very simple to use. The 3 banana plugs are used to patch the unit into a +/- 20 VDC bipolar supply and the two edge connectors plug into the module under test. The line in connector is an XLR female that can be patched to an oscillator, music source, pink noise source, analyzer signal, etc. There are 2 XLR male connectors for the module group insert send and direct send, for monitoring and testing. The line input is connected to the mic preamp input via a balanced pad (approximately 30 dB, I believe). The lower edge connector includes a regulator that provides +5 volts to the logic circuits in the module under test. All connectors are clearly labeled.
Includes a copy of the Trident edge connector pinout sheet and module schematic. Guaranteed to work properly.
