KENWOOD KA-V7700

Commentary

An AV amplifier equipped with AV surround functions such as Dolby Pro Logic and DSP in addition to a genuine high-quality amplifier.

Equipped with a DSP logic circuit that adds steering logic (directional enhancement circuit) to DSP mode.
By adding initial reflection sound and reverberation sound with DSP to the signal output from the directional enhancement circuit, a powerful sense of presence is obtained.

Equipped with a digital Dolby Prologic Surround Decoder using newly developed DSP LSI.
In addition to the steering logic (directional enhancement circuit), which is important for Pro-Logic, the Dolby B circuit and auto input balance are processed by digital signals. This eliminates problems such as the linearity of the VCA (voltage control amplifier), accuracy of analog parts, and circuit complexity, which were problems when the Pro-Logic stage was composed of analog, and improves sound quality.

Equipped with a DSP presence circuit, it controls initial reflected sound and reverberation sound by digital signal processing, and creates sound field space by combining with main signal.
The structure consists of a 64 fs 4th-order noise-shaping 1-bit A/D converter that converts analog signals into digital signals and a dedicated DSP (digital signal processor) for arithmetic processing. Six sound field patterns can be selected.

Equipped with DSP parameters to create original sound field patterns.
You can adjust the effect level to adjust the feeling of live, the seat position to move the listening position forward or backward, the wall to simulate the sound reflected from the wall, and the room size to simulate the size of the room by adjusting the interval between early reflections.
The adjusted data can also be stored using the remote control.

It is equipped with a channel mode that distributes the presence signal according to the number of speakers and the setting.
By changing the channel mode, you can enjoy DSP logic in front 2 ch + center 3 ch or front 2 ch + rear 2 ch 4 ch.
There is also a position where you can enjoy DSP presence only with front 2 ch.

Equipped with a center mode that can be selected depending on the shape of the center speaker and whether or not it is present.
You can choose from 3 patterns in total, normal for small center speaker, wide for medium or larger center speaker, and phantom for use when there is no center speaker.

The delay time can be adjusted according to the room environment and speaker settings.

Because L/C/R channels are located on the back of the screen, there is software that emphasizes the high tone.
In order to play such software, it is equipped with a cinema screen which can adjust recording characteristics in three stages.

The power amplifier section uses a 5-channel discrete configuration.

The internal structure has been thoroughly reviewed and the PCB separation structure, power transformer winding separation, and microcomputer earth separation have been implemented to reduce signal interference between each stage.

Equipped with a VIDEO independent REC selector that can record separately.

It has a source direct function.

Built-in pre-out terminal for front / center / rear, and built-in mono-out terminal for sub-woofer.

Memory remote controller with multi-controller function is included.
