Description
Interface Valcom V-TCM talkback station cards with one-way amplifiers, self-amplified speakers, and horns using the V-LPT paging adapter, which matches the level and impedance of the talkback audio output to the input requirements of one-way paging equipment.
The Telecom Spot Expert Review
Impedance mismatches between talkback station card outputs and one-way amplifier inputs are a common source of distortion and low audio levels in hybrid Valcom installations. The V-LPT resolves this cleanly — it converts the V-TCM's 1000-ohm output to the sub-20-ohm level that one-way amplifiers and self-amplified speakers expect, without adding noise or requiring external power. A straightforward adapter that prevents signal chain problems before they become field complaints.
