The D-75A is a stereo power amplifier that is perfect for moderate power applications, such as recording or broadcast studio near-field monitoring, video suite audio monitoring, a recording or broadcast headphone amplifier, or a small paging system.
The D-75A is designed to ensure reliable operation with a wide variety of loads and is convection cooled. AB+B circuitry ensures efficient use of output transistors while incorporating protection against shorted, open, mismatched or low-impedance loads. This high reliability is particularly important in reducing maintenance costs.
Additionally, the amplifiers sonic excellence also makes it a very good choice for a personal listening environment. The D-75A is backed by a three year, fully transferable no-fault full warranty.
Stereo power amplifier with accurate, uncolored sound and very low distortion
AB+B class circuitry yields maximum efficiency with minimum crossover "notch" distortion
Ultra-low harmonic and inter-modulation distortion result in the best dynamic transfer function in the industry
IOC (input/output comparator) alerts of any distortion that exceeds 0.05% to provide proof of distortion-free performance
Bridged mono and stereo operation
Detented level controls for precise repeatability
Convection cooling system dissipates heat through the heat sinks and chassis for optimal cooling and maintenance-free operation

The amplifier is totally convection cooled. The entire aluminum chassis acts as a conductor to dissipate heat. The covers and front panel extrusion also act as heat sinks. Much of the unit's heat is conducted through the extruded front panel. This design is used so that front panel contact with the equipment rack will also dissipate heat
