The Denon DRA-25 is a home stereo receiver manufactured in the late 1980s. In November of 1988, the DRA-25 had a retail price of $300.
Denon is a Japanese consumer electronics company known for manufacturing high-fidelity home and professional audio equipment. In 1972 the company played a pioneering role in the development of digital audio, engineering the world's first Pulse Code Modulation (PCM) studio recorder. PCM later became the standard format for compact disc recordings.
The Denon DRA-25 receiver has input connections for three different home audio components. There are inputs for a CD player, a cassette tape deck and an auxiliary input that can be used to connect a turntable or other audio component.
On the back of the device are two AC outlets, one switched and one unswitched, which can be used to power audio components or other devices. The switched outlet is rated for 100 watts and allows for any connected device to be turned on and off with the receiver. The unswitched 250 watt outlet provides constant power to any connected devices.
The Denon DRA-25 receiver has a total speaker power output of 120 watts, or 30 watts per channel. Two pairs of stereo speakers can be connected to the receiver via color-coded binding posts on the rear of the device. Audio can be routed to either pair of speakers or to both pairs simultaneously.
The Denon DRA-25 receiver features a black metal case and an LCD multi-function display. The display is used to indicate a variety of information such as AM or FM frequency, CD track number and input device type.
The front panel has a set of eight buttons that allow the user to program up to 16 presets for AM and FM radio stations. Tuning is accomplished via a pair of buttons. There are toggle switches for both pairs of speakers, tape monitor and CD direct. Control knobs are used to adjust bass, treble, balance, volume and variable loudness.
There is a 1/4-inch input for a pair of stereo headphones.
