Denon AVC-3030 Precision Audio Component/AV Surround Amplifier - Missing Volume Dial Cover - Tested Working This AV amplifier uses New Super Optical Class A circuit to achieve purer sound reproduction. DENONs unique New Super Optical Class A circuit is mounted on the power amplifier for front and center.This circuit allows pure class A amplification up to the level of listening power, and non-switching class A amplification which is effective in improving crossover distortion and switching distortion at high output.The high-speed bias control circuit controls the amplification method depending on the input level. An optical element is used to transmit the control signal from the bias control circuit to the power transistor bias circuit. This eliminates the interference between the main signal system and the bias control circuit, and achieves high-speed bias control.F is the output stage.T20 MHz, Pc150W power transistor is used. Dolby The DENON specially selected IC is used in the Pro-Logic Decoder to achieve low distortion, high S/N, and improved dynamic range. In addition to the Dolby Pro Logic, it is equipped with Theater and Live by adaptive matrix and DSP sound field simulation, and Mono Movie, Classic Concert, Rock Concert, Church and Stadium by which you can enjoy DSP presence with 4 parameters.

The power supply section is equipped with a toroidal transformer that enables highly efficient regulation and reduction of leakage flux. It is equipped with a AVSE circuit that amplifies the low range and realizes more powerful surround playback.In addition, it is equipped with a cinema equalizer that improves movie software that emphasizes and records the dialogue of a person for a theater. The CD/VDP audio circuit has a direct function with a mechanical relay.The transmission system from the input to the output of the preamplifier section is kept as short as possible to achieve high sound quality in 2-channel stereo reproduction. The built-in wide-aspect interface video selector automatically detects and adjusts the angle of view of standard and high-definition images.It also has a built-in broadband video amplifier and a 4-channel discrete audio input. Equipped with voice input Line 5 and voice + image input Line 5.In addition, it has a Rec out select function. It is equipped with simulcast playback function, on-screen display function and auto input balance function.

Tested working. The front bottom right corner has a crack. I will beat their price!If you find the same product in similar condition for a lower price, message me and I will beat it by 5%. No other offers please.

This was Denons Top of the Line when New. Works great as a Receiver or Pre Amp. When using surround sound there is static in rear channels. Sounds just fine when just using 2 channel stereo. Remote works great . Very high build quality means its also very heavy at over 35 pounds .
