KENWOOD KA-V1000R

Commentary

This AV surround amplifier pursues sound quality and operability for full-scale AV surround sound.

When connected to a TV, it is equipped with a superimpose function that can display functions such as audio and video source selection, recording and recording status, surround sound, and video enhancer on the TV screen.
This character is imposed for about 5 seconds and displays the source selection, recording, recording status, etc. for interactive operation.

Equipped with 4 types of surround functions.
You can enjoy Dolby Surround which plays back movie and concert software created by Dolby Surround system, Theater Surround which creates the reverberation effect of the theater with stereo movie software which is not Dolby Surround system, Stadium Surround which can enjoy sports and events in a large space with realistic sound, and Synthetic Surround which creates surround sound by creating pseudo rear component even in monaural source.

It uses a 16-bit digital delay that can switch between 4 different delay times of 10, 15, 20 and 30 ms, so you can enjoy surround sound more effectively according to the source and listening room condition.

It is equipped with a total of 12 input terminals of audio Route 6 and visual Route 6.
You can also adjust sharpness and detail with a built-in video enhancer that corrects the image and creates a clear image.

It is equipped with audio injection that can output video signal and audio signal separately, and you can enjoy playing CD sound while playing video and other images.

It comes with a large-capacity storage type remote controller. It is possible to program the remote controller of AV equipment such as TV and video and control all by one device. To set the memory, place the remote controller to be stored and the remote controller to be stored face to face, and press both keys to finish the memory.
In addition, the motor drive volume is adopted, and the volume can be adjusted by remote control.

It is equipped with the function of ITRS which can record and record the independent source.
For example, you can record on a VHS VTR, aircheck a BS tuner on a beta VTR, and record an FM tuner on an audio deck at the same time.

It is equipped with CD direct and line straight switch which connects the signal directly to the power amplifier in the shortest distance.

Kenwood's unique Σ drive is used for the power amplifier section.
By applying the NF loop to the speaker terminal of the amplifier, the impedance of the pattern and wiring material, the phase compensation coil, the contact point of the relay and the selector switch of the speaker, and other parts that used to be outside of the NF loop are put into the loop to improve the performance at the output terminal.
