DENON DRA-75VR
¥ 89,800 (around 1987)
Commentary
An AV receiver with a synthesizer tuner and wireless remote control.
We emphasize the quality of the amplifier section and incorporate DENON's amplifier technology.
The power stage adopts a non-switching class A power amplifier stage with a complete DC amplifier configuration.
The main signal and power supply are completely separated via a heat sink to prevent quality degradation.
Equipped with a 16-station random preset FM/AM synthesizer tuner.
16 random preset memories are available by combining FM and AM stations.
It uses a 4-way tuning system. For example, one touch random preset tuning that directly calls the desired station out of 16 stored stations, automatic tuning that automatically finds and tunes radio waves by auto-scanning, manual tuning that detects weak radio waves, and last-channel memory tuning that selects the station that was last received.
A terminal type low-impedance loop antenna is used in the AM section.
Two video devices can be connected.
In addition, by using the simulcast copy function, you can freely combine video and audio.
Equipped with an MC/MM phono equalizer amplifier.
It is equipped with a processor loop can be used to connect surround processors and graphic equalizers.
Equipped with a tone control circuit and a variable loudness control circuit.
Equipped with a reset-type high-speed protection circuit.
