Commentary
An AV amplifier compatible with Dolby digital.
By adopting 24 bitDSP chip, it is compatible with 5.1 ch Dolby digital surround.
In addition, it is equipped with Dolby Pro Logic and Dolby 3 stereo so you can enjoy various surround sound depending on the source.
It is also equipped with the Midnight Theater Mode, which can be used to control the dynamic range of Dolby digital playback when it is not possible to play at a sufficient volume in the middle of the night.
(Midnight Theater Mode only works with software that supports dynamic range control)
20-bit A / D and D/A converters are used for analog-to-digital conversion.
Equipped with an FM/AM stereo tuner, you can preset up to 40 FM/AM stations at random.
It is also equipped with a preset call function that allows you to listen to the stored stations in order.
The front 3 ch uses a banana plug-compatible screw-type speaker terminal.
The pre-out terminals for the center, surround and sub-woofer are used for perspective viewing.
Uses FL display with dimmer function.
It uses AI volume.
In addition to the basic operation with the attached remote control, it is equipped with a macro play function that allows you to register continuous operation such as turning on the power of the amplifier and MD for remote control, or playing MD.
The included remote controller is equipped with two infrared transmitters, one of which transmits signals in a linear direction over a long distance, and the other of which distributes and transmits signals over a wide range over a short distance.
