Bosch Plena PLE-1P240

High performance slave / power amp. 240 watts with 100v, 70v and 8 ohm outputs.

The Bosch PLE-1P240 is a cost effective 240 watt power amplifier for use on 100 volt line distributed sound systems as well as low impedance music systems using 8 ohm loudspeakers.

The PLE1P240 has one line input with a loop through output. Overload, overheat and short circuit protection inconjunction with a temperature controlled fan ensure long term reliability.

A headphone socket is available for monitoring, all other connections and input volume control can be found on the rear to prevent tampering.

The 100 volt line input can be used to take a signal from a 100 volt line speaker line in order to extend an existing sytem.

An integral 24 VDC battery charger trickle charges a 24 VDV backup battery (available separately) which will power the amplifier in the event of a mains failure.

The Bosch PLE 1P240 can be used freestanding or mounted in a 19″ rack using the rack mounting brackets supplied.
