Pro Intercom PS300 Power Supply

Power Supply, 24V Linear, 3 Outlets, No Switching The PS300 is identical to the PS301 except that it does not have program audio facilities and is less expensive. The PS300 is a 3-circuit Power Supply with a unique hybrid configuration. Microprocessors operate all the switching, routing, and supervision functions, while the audio paths and the core power supply remain analog. The result is a station with unrivaled flexibility, muscular reliability, and clean, smooth audio. The PS300, as in all the 300 series master stations and power supplies, has a large toroidal transformer which gives off virtually no stray-field radiation to interfere with the other devices with which it shares rack space. Those power supply components which create heat are mounted on a massive heat sink, and, when neces- sary (rarely) get extra cooling from a thermally regulated cooling fan. Each of the 3 PS300 circuits is independent of the others, except for sharing the toroidal transformer and its peripherals.
