DIATONE DA-U10AV

Commentary

An AV amplifier designed for surround sound but with a focus on CD playback.

Equipped with a super-dynamic delay line circuit, the dynamic range is improved by 30 to 40 dB compared with conventional analog delay circuits, and a dynamic range of 90 dB or more, comparable to that of digital delay systems, is secured.

Multi-feedback servo system is used for the feedback circuit of the amplifier section.
In this system, the servo circuit consists of two systems, a main loop for controlling the music signal and a servo loop for increasing stability in the ultra-low frequency range. This improves the resolution of the amplifier and the low-frequency drive capability.

Using a differential charge method, the surround signal output from the rear amplifier is supplied with opposite phases between the left and right channels. This averages the supply state and increases the power capacity of the rear amplifier to a maximum of 2 times. In addition, the instantaneous current supply capability is greatly improved to improve the drive capability of the speakers.

The power amplifier section is equipped with a 4-channel power amplifier in which the front and rear power amplifiers are completely independent circuits.

Audio condensers, large-capacity power cords, and pattern design studies have been conducted to improve sound quality.

The surround section is equipped with a surround processor that supports Dolby surround sound.
There are four modes available : Dolby Surround, High Presence Position for HiFi Audio, Theater Position and Simulated Stereo for モニラルソース.

It supports a total of seven sources, four audio channels and video Route 3 channels.

Equipped with LED surround indicators, you can display the level of the L channel, R channel, surround L channel and surround R channel.

It uses an interactive remote control system that allows you to switch functions, TV and video channels, etc. in an interactive mode of remote control operation and superimpose.
Equipped with an AV remote control function, you can switch functions and volume up / down, switch TV and video channels in combination, and switch Play/Stop / power on/off.
