KENWOOD KA-V7000

Commentary

AV amplifier equipped with Dolby Pro Logic Decoder.

In Dolby stereo, the front L/R and surround components are encoded and recorded as 2-channel stereo. By decoding this signal, you can obtain realistic surround effects.
The Dolby Pro-Logic Surround Decoder adopts a directional enhancement circuit (steering logic), and the basic design is 4 ch compared with the conventional passive type decoder, which assumes 3 ch reproduction, and realizes more accurate localization.

The power amplifier section is equipped with a 150W/ch power amplifier at the front left and right, and a 50W + 50W amplifier for the rear.
The center channel is designed for use with the current amplifier, and has outputs for the center channel and sub-woofer.

The center channel can be switched between 3 modes of normal / wide / phantom.
In the wide mode, the output separated by the directional enhancement circuit is output as it is. In the normal mode, the signal below 100 Hz is cut off and only the signal above 100 Hz is sent to the center, which is effective for small speakers.
Phantom is a mode in which the center speaker is not used. It splits the center channel signal and distributes it to the left and right speakers.

Equipped with a digital delay circuit, it can be adjusted in 1.5 ms steps in the range of 15 ms to 30 ms for Dolby Pro Logic Surround and 0 ms to 30 ms for other surround modes.

Equipped with a test tone circuit, balance adjustment of each channel is possible.
In addition, it can be operated manually or automatically, and the level can be set accurately using the remote control.

During surround bypass, it functions as a front-only amplifier, and the source direct switch reduces internal signal degradation and interference between signals.

It uses logical flow construction to minimize signal paths and eliminate listening to music and video signals.
In addition, we have adopted an internal layout that eliminates the influence on signals, such as a PCB separation structure that is resistant to external vibration and separation of power transformer windings.

It is equipped with a large φ 60 insulator that uses special foam rubber.
In addition, a new structure has been adopted for the contact surface between the insulator and the set bottom to reduce harmful vibrations from the outside.

The TV ON SCREEN function allows you to view and control the current audio and visual and visual source, recording status, surround mode, level, delay time, current video enhancer status, and sources that can be recorded.

It is equipped with ITRS function which can record and record sound of independent source of Route 3.

Equipped with an audio injection function that can output video and audio signals separately.

The output for the subwoofer is an L + R monaural line output. It cuts out the high frequency components that are not necessary for the woofer and outputs 110 Hz or less.

It comes with a learning remote control that can program and control most devices such as TV and VIDEO. The memory is completed by simply placing the memory remote control and the memorized remote control facing each other and pressing both keys.
The RC-V7000 is a 3-way switching type with 72 basic keys. In the audio and video positions, the upper half is a memory key and the lower half is an amplifier operation. In the AUX position, all keys are memory keys, and a total of 160 keys can be stored in all three ways.

It features a 16-character, 2-column LCD dot matrix to display information.
