ALT 8x8 G3 Transfer Unit EN 54‐16

The ALT 8x8 is a line transfer unit for Audico Avec public address and voice evacuation system. It converts ADA 8x8 central units’ low impedance (8 Ohms) outputs to 70-100V constant voltage lines. The ALT contains 8 separate transformers.

ALT also delivers the 24VDC priority voltage for attenuators’ bypass relays, use of priority voltage ensures the important message is heard everywhere in spite of the current position of the volume setting. Output lines can be connected parallel to increase the power delivered to a single line.
