The PMA-700V are high power amplifier equipped with a Dual Super Non-NFB power amplifier for crystal clear reproduction of digital sources. Added to his extremely pure non-feedback amplification system, the use of DC circuitry without a single coupling capacitor in the signal path from the MC input to the speaker output terminals and a new current mirror circuit in the voltage amplification stage, using high speed transistors with excellent high frequency response, all work to obtain a high slew rate of ±350 V/µsec.
Furthermore, a Pc 80W , Frequency Response 20 kHz multi-emmiter structured large chip power transistor is used for the output transistor. This outstanding output transistor and the mighty power source which greatly increases current supply capacity provide truly high power.
Pure Current Supply - decreases ynamic Intermodulation DIstortion Distrotion by 60 dB
The large size heat sink and toroidal transformer, as well as audio capacitors for large scale capacity (33,000 µF) increase momentary current supply capacity to the same level as high-output top-of-the-line separate power amps. The use of this Pure Current Supply circuit with Denon's original bridged block capacitor system suppresses dynamic Intermodulation DIstortion , and together with the high capacity power transformer provides high dynamic power.
Electronic Switches and Ideal Chassis Construction Eliminate External Noise
In order to eliminate the influence of magnetic and electrical noise, the chassis construction divides the power supply section and main signal circuitry at the heat sink, thus markedly reducing mutual interferences. In addition, electronic switches are used for the input se;ectors, reducing wiring and resulting in an ideal layout to make signal paths simple.
Two sets of Video Inputs
VCR or Laser Disc Video input selection is performed with a newly developed complimentary push-pull circuit which provides low distortion and wide range response (DC - 10 MHz ±1 dB) for excellent image transmission performance. One set of inputs is located on the back panel, and the other one is on the front panel for convenient use.
