2716 Power Amplifier

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 signals 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.
