DENON DRR-780

Commentary

Reverse deck with horizontal loading system.

It uses a tray type horizontal loading mechanism that does not impose strain on the rotating system and reduces modulation noise by suppressing vibration in the thrust direction of the flywheel. In addition, it uses 3 motors for reel, capstan, head lifting and loading, and realizes smooth operation.

It uses a quick reverse mechanism. When recording, when the end of the tape is near, the infrared sensor catches the lead tape portion, and it flips at high speed and automatically makes one round trip. It also operates during playback, and it can be played for a long period of 5 consecutive times.

Equipped with a cassette stabilizer made of ceramic composite material and a ceramic composite cassette tray (C. C. C. T) to enhance the vibration absorption effect of the cassette half.

Equipped with Dolby HX Pro, the over-bias phenomenon is prevented by always keeping the effective bias value at an appropriate value.

Equipped with a Dolby B/C type noise reduction system.

Equipped with linear time digital counter with memory stop mechanism using FL tube.
It usually shows the elapsed time in minutes and seconds, but if you want to know how much time is left on the tape, press the tape size button and then the Remain button.

Uses a non-slip reel drive system that maintains the proper tension of the tape.

The recording / playback amplifier section uses a DC amplifier configuration and ± 2 power supply system.

Equipped with a Rec return key.

Equipped with a bias fine adjuster.

Equipped with FL peak level meter.

Built-in functions such as music search, auto recording space, auto tape selector, and MPX filter (remote control only).

Equipped with output level control which can also adjust the volume of headphones.

Wireless remote control is included.
