• Three circuits rather than the usual two.
• Circuits are linkable (A + B) or (A + B + C) with auto termination impedance adjustment.
• Each circuit’s termination can be lifted via rear panel DIP switches.
• Mic switch on each circuit can be tapped for locking or held and released for momentary.
• Full duplex, hands-free operation, in moderately noisy environments. (with optional noise-canceling gooseneck mic.)
• Front panel 4-pin XLR may be used for gooseneck mic. or headset.
• Gooseneck or headset mic. may be dynamic or electret. Lighted front panel switch sets choice.
• Front panel green LED indicates presence of 24VDC across the three circuits.
• Three front panel flashing red LEDs report trouble status of each circuit. Other circuits are not affected.
• System auto-resets when the problem is eliminated.
• While switching is all electronic, the audio paths remain analog providing comfortable long-term listening.
