Would be a great add for any audiophile collection. Had one owner only and very well taken cared for. Item sold as is in working condition. SHIPS ALL LOWER 48 STATES AND NO PO BOXES ONLY*************************************************** *********Item Description and Specifications********** Powerful amplifier with practically distortio-free performance. PMA-500V features: Denon's Non-NFB amplifier for extremely pure, high-speed amplification thanks to complete separation of the power amplifier stage into voltage amp and power amp Pure Current Supply circuit with Denon's original bridged block capacitors suppress dynamic IM dustrotion by 60 dB 7 sets of audio input terminals Electronic switches and ideal chassis construction eliminate external noise Super Equalizer with range response Independent subsonic filter switch provided for record playback with ann MC or MM cartridge Non-NFB Power Amplification - Striking Power with Digital Sources The PMA-500V includes Denon's original Non-NFB amplifier for extremely pure, high speed amplification. By completely separating the power amplification stage into voltage amplification and power amplification stages,, the influence of counter-electromotive force from the speakers is eliminated. As a result , iy has been possible to reduce all types of distortion to nearly zero, including dynamic distortion such as tim, to obtain high quality amplification.. In addition, the PMA-500V uses large capacity (Pc 100W) high speed transistors for high current drive, providing at the same time both the sharp, clear sound characteristics of Non-NFB amplification, and a high slew rate of ±150 V/µsec Pure Current Supply Decreases Dynamic IM Distrtion by 60 dB The PMA-500V also incorporates a large size heat sink, a multiple shielded large transformer, and capacitors for large scale capacity (27,000 µF total). The result is a stable power supply with high dynamic power and strength even for the ultra-low frequencies. Additionally, the Pure Current Supply circuit with Denon's own bridged block capacitor system suppresses dynamic IM distortion greatly for improved sound quality 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 selectors, reducing wiring and resulting in an ideal layout to make signal paths simple Newly Developed Subsonic Filter and Super Equalizer An ezcellent subsonic curve is achieved (16 Hz; -12 dB/oct) for both Mc and MM playback. An independent switch is provided for tuning each subsonic filter and phono equalizer on and off. Working together with the wide-range 920 Hz - 50 kHz ±0,3 dB, MC). Super Equalizer, optimum conditions are ensured for refined analog disc reproduction Additional Features: Two sets of Video Inputs A rotary speaker selection switch Real-time tone control with no reduction in sound quality Specifications: Power Amplifier Section Rated Output Power (both channel driven): 80 W per channel min.
