Communications Systems | PLN‑1P1000 Plena Power Amplifier PLN‑1P1000 Plena Power Amplifier ▶ 1000 W power amplifier in a 3U high housing ▶ 70 V / 100 V and 8 ohm outputs ▶ Dual inputs with priority switching ▶ 100 V input for slave operation on 100 V speaker line ▶ Temperature-controlled forced front-to-back ventilation, directly stackable ▶ Mains, battery back-up and pilot tone supervision The PLN-1P1000 is a powerful 1000 W power amplifier in energized) relays are provided for each supervised a 3U high 19” case for rack mounting or tabletop use. function. These relays are always active regardless of the LEDs on the front panel show the status of the amplifier: switches on the rear panel. power, audio output level, and supervised functions. This Input high-performance unit fulfills a wide range of public The system has two balanced inputs with priority control, address requirements at a surprisingly low cost. each with a loop-through facility. This makes it easy to connect remote systems that require priority control. An additional 100 V line input can connect the amplifier to a Functions 100 V loudspeaker line, to provide more power to remote Dependability locations. The amplifier is protected against overload and short Output circuits. A temperature-controlled fan ensures high The amplifier has 70 V and 100 V outputs for constant reliability at high output levels, and low acoustic noise at voltage loudspeaker systems, and a low impedance output lower output levels. An overheat protection circuit for 8 ohm loudspeaker loads. A meter with LED-bar shows switches off the power stage and activates an LED on the the output level. front panel, if the internal temperature reaches a critical The PLN-1P1000 has two separate priority controlled 100 limit due to poor ventilation or overload.
