Denon POA-5000 Six Channel Amplifier
In 1991, Denon introduced a great multi-channel (6CH) power amplifier Denon POA-5000 AV power amplifier which carries a new optical class A circuit original with DENON in all the channels.
In the new optical class A circuit, sound quality which was excellent in no one but [ Class-A ], and high efficiency are realized by [ with a general pure listening power level ] carrying out magnification operation as a Class-A. Moreover, by "optical combination" which transmits the control signal from a bias control circuit to a bias circuit, while eliminating completely interference between the main signal system and a bias controlling circuit, high speed-initialization of bias control is realized by using an optical element.
Each channel of a front, a center, and rear becomes independent, respectively, and a setup of a stereo and a mono-bridge is possible for it.
At the chassis construction, each of a control part, L channel power stage, R channel power stage, and a power-source part is completely separated using a copper-coating chassis, and the dirt of sound and muddiness are eliminated by suppressing a mutual intervention to the minimum.
Level volume is carried in each input and adjustment of a surround level is possible. Moreover, in order to pursue a more nearly quality sound, the direct switch which bypasses each volume is equipped.
By connecting with AVP-5000 of AV preamplifier by a remote cable, AVP-5000 is interlocked with and power-source ON-STANDBY is switched automatically. The high-speed protector circuit is carried.
