It can be used as a general-purpose power amplifier for electroacoustic applications. Uses Driver for loudspeakers, artificial mouths, etc. General-purpose audio power amplifier Power amplifier for audio analyzers Features Output-level meter Selectable gain Two balanced inputs Easy to install in a 19″ rack Power Amplifier Type 2716 has two channels which may be used independently or jointly (using the Link A+B and Phase Reverse B switches). Input level requirements are matched by those **s generated by Investigator? Type 2260D. Total output power is in the order of 300 W and is relatively independent of load; this matches the requirements for driving the OmniPower Sound Source Type 4296 with a wide margin of safety against damaging the speaker units. The Type 2716 will deliver full output power for a duty cycle of 1/3, matching typical operating modes in building acoustic measurements. Power Amplifier Type 2716 is of compact size and low weight for its output power. It has the same features and protection circuits normally found only in higher powered amplifiers. This makes it one of the few really professional power amplifiers in its class. Eight 150 W bipolar power transistors make up the complementary out put stages. These are mounted directly metal-to-metal on an aluminium cooling fin. Because of this, passive cooling is possible; no (noisy) cooling fan is needed.
