The ALT 8x8 is a transformer unit for Audico Avec Public Address and Voice Evacuation system. It converts ADA 8x8 central units’ low impedance (8 Ohms) outputs to 70-100V lines. The ALT contains 8 separate transformers, each having 8 Ohms primary coil and secundary coil with tappings for 70 and 100V (factory setting). ALT also delivers the 24VDC priority voltage for attenuators’ bypass relays, use of priority voltage ensures the important message is heard everywhere inspite of the current position of the volume setting. Output lines can be connected parallel to increase the power delivered to a single line.
