This makes it possible for the PTM-1645 to power as many as four pairs of 8 ohm speakers per channel for a total of up to 64 speakers! The PTM-1645's enormous high current power supply and robust output circuitry provide stable 2 ohm operation. The PTM-1645 features ADA's cutting-edge PAC (Programmable Amp Controller) circuit, which enables RS-232 and/or DC triggering of independent zones.
This feature also makes it possible to have multiple amplifier channels track a specific room/zone when employing multiple speaker pairs in that area. The PAC circuit facilitates simple one touch operation to turn on a room in the multiroom system. The PTM-1645's rack mount design and detachable rear panel connectors make it easy to install into a standard 19-inch equipment rack. The PTM-1645's built in temperature control circuit helps maintain long-term reliability.
