UHC-MOS is an ideal amplifier whose power supply performance is superior to that of bipolar transistors and incorporates the sound quality advantages of MOS-FETs. The PMA-700V's UHC-MOS is provided in a single push-pull configuration that eliminates deviations in the amplification stage and balances high power with delicate musical details. [. . . ] This circuit masterfully reproduces the full sonic range, from the delicate musical nuances to the powerful climaxes of rich musical expression. High-current, dynamic power supply, to support high speed and large current flow A low-noise Schottky barrier diode, well known for its superior switching characteristics, has been used in the rectifier circuit. The Schottky barrier diode used in the PMA-700V has 1. 5 times more capacity than previous models, which provides ample current capacity to accommodate ongoing successions of large bursts in sound while preserving its power and stability. Lower impedance has been achieved by doubling the normal thickness of copper foil used in the power supply circuitry, a design that adds stability to the current supply. The use of custom parts for the block capacitor, thoroughly tested for their contribution to high sound quality, further underscores Denon's uncompromising approach to audio technology and impeccable sound. Direct Mechanical Ground Construction to minimise unwanted vibration The PMA-700V features a redesigned construction that thoroughly suppresses the adverse influences of vibration and electrical noise. Compared to previous models, the PMA-700V has a lower centre of gravity where the power amplifier board has been mounted closer to the bottom of the chassis, a construction that protects the circuitry from vibration. A twin monaural configuration with L/R symmetry has been adopted for the power amplifier block. Wide-range playback, supporting Super Audio CD The PMA-1500AE achieves an effective frequency response of up to 100 kHz. The use of a lowimpedance volume control also suppresses noise generated inside the amp during actual use to ensure optimum resolution. This wide-range playback capability is ideal for high-grade audio format such as Super Audio CD. Microprocessor Stop Mode, for pure enjoyment of music In this mode, when no operation has occurred, the PMA-700V stops microprocessor operation. This stops clock oscillation in the digital circuitry and allows you to enjoy a purer musical sound. Useful function System remote control unit to control not only the amplifier but also a CD player (*1) The supplied remote control unit not only operates the PMA-700V but also the Denon DCD1510AE Super Audio CD player. The buttons used most frequently have been arranged for easy operation when the unit is held in one hand. (*1) PMA-700V's remote control unit is the same as DCD-1510AE's one. RC-1143) Power Amp Direct Input Others · High-performance phono equaliser · Parts strictly selected for high sound quality · Gold-plated speaker terminals The PMA-700V provides high-grade, goldplated speaker terminals that allow bi-wired connections.
