Crown D-75A 1U Power Amp: 40w per Channel @ 8 Ohms

An unquestioned long-term standard, D Series amplifiers are found everywhere in the lab, on the road, in public facilities, in the studio and at home. The D Series is an example of Crown's commitment to developing long-term, reliable amplifier technology. The D-75A is perfect for moderate power applications such as recording or broadcast studio near-field monitoring, video suite audio monitoring, a recording/broadcast headphone amp or a small paging system. Designed, built and carefully checked to ensure reliable operation with a wide variety of loads, Crown D Series amplifiers are convection cooled. Their high reliability is particularly important in reducing maintenance costs.

    * Balanced three-pin Neutrik combination XLR and 1/4" phone jack for each channel
    * Four-terminal barrier block (two per channel) and stereo headphone jack
    * AC line has a standard three-wire grounded connector
    * Powerful AB+B class circuitry yields maximum efficiency with minimum crossover "notch" distortion
    * IOC® (Input/Output Comparator) alerts of any distortion that exceeds 0.05%
    * Signal presence indicators verify the presence of amplifier output
    * Detented level controls for precise repeatability
    * Very low noise and wide dynamic range exceed the audio specifications for CDs
    * High damping factor provides exceptional loudspeaker motion control
    * Convection cooling system dissipates heat through the heat sinks and chassis for optimal cooling
    * Mounts in a standard 19" (48.3 cm) rack
