AM/FM STEREO RECEIVER
D R A-775RD
An Innovative Receiver That Does Just About
Everything, Including Multi Room Entertainment
The DENON DRA-775RD receiver is a truly versatile component meeting today's
increasingly complex A/V and pure audio system requirements. Not only does it deliv-
er reliable high power and ensure high-quality sound, it also includes video input and
output capabilities as well as DENON'S innovative Multi Room Music Entertainment
System and easy-to-tune RDS broadcast reception capabilities. The Multi Room Music
Entertainment System lets you set up an amp and speakers in a separate room, connect them to the DRA-775RD, and enjoy program sources independently of the listener in the main room. The remarkable DRA-775RD deserves a close look and a listen as
the best possible solution for your audio/video system needs.

DRA-775RD
Powerful, Versatile Amplifier
High-Quality Power Amplifier
High-speed, high-power transistors employed in a rational circuit configuration reflect DENON'S advanced amplifier
technology and ensure a very hefty, clean power output.
Pure Current Power Supply
The DRA-775RD is endowed with the same type of power supply circuitry as DENON'S best integrated amplifiers.
Known as the Pure Current Power Supply, it incorporates DENON'S original circuit and high-capacity transformer to sup-
press dynamic IM distortion by 60 dB, yielding high dynamic power.
Low-Impedance Speaker Drive
The power supply and power amplifier stage are designed to respond even to sudden dips in speaker impedance, so
that the speaker drive remains stable under all load conditions.
Discrete Chassis Construction
The signal path in the DRA-775RD is kept as short as possible from input to output. The power amplifier section, which
handles high-level signals, employs separate heat sinks in a totally separate symmetrical layout for the left and right
channels. Power supply circuitry is located close to the respective destinations to further prevent signal losses and elimi-
nate interference.
Frequency Synthesis Tuning
RDS Tuning System
The DRA-775RD offers four RDS features: RDS (station) Search, Program Type (PTY), Traffic Program Identification (TP),
and Radio Text Message (RT).
RDS Search lets you search for stations currently broadcasting RDS signals. PTY lets you select from among 22 types of
music and programs you want to listen to-such as Classical. Jazz, Rock. Top 40. News, Sports-and a station broadcasting
the selected type is automatically tuned in. TP, when turned ON, automatically tunes to a station which is about to
broadcast a traffic report. And RT receives and displays a message of up to 64 characters that the station tuned in is cur-
rently transmitting.
AM/FM 40 Station Random Preset Memory Tuning
The DRA-775RD offers random preset and recall of up to 40 stations. Tuning is as simple as pressing a button.
Auto Preset Memory
A maximum of 40 FM stations can be searched by the tuner and automatically stored into the preset memory. This fea-
ture is useful when you do not know all the frequencies of local stations.
Sophisticated Tuning Circuit Design
Thanks to the use of large-capacity microprocessor ICs in the tuning section, reception drift is a thing of the past. The
DRA-775RD also has a 3-pole varactor diode in its front end to guarantee accurate input of station frequencies.
• Improved AM Reception

Your Audio/Video Control Center
Video and VCR Terminals
Audio systems can be easily upgraded to include versatile reproduction from video as well as audio sources, because the
DRA-775RD is also equipped with VDP, VCR and Video Aux input and output terminals.
Video Select Switch
The DRA-775RD's Video Select function lets you select the desired video sources independently on the audio sources.
Easy Simulcast Copy
This feature not only permits reception and recording of FM/TV simulcast programs onto videotape, but it can also be
used to combine, for example, the sound from a CD with the picture from a video disc.

Multi Room Music Entertainment System
Multi Source Function
The DRA-775RD's Multi Source function lets you select different audio or video sources for viewing or listening Different
sources can thus be enjoyed in the main room and the second room simultaneously. This novel feature gives you consid-
erable flexibility when setting up and enjoying your system with the DRA-775RD. The output level, adjustable by the
remote commander, is as much as 1V, enough to operate the optional power amplifier placed in a second room.
Equipped for Room-to-Room Remote Control
Since A-B switching of speakers is possible by remote control, the DRA-775RD can be used in configuring a room-to-
room remote control system by adding the optional RC-616/617S/617W/618. And because direct terminals for the RC-
616 (IF Re-transmitter) are provided on the DRA-775RD, audio systems in locations that do not easily receive infrared
based emissions can also be reliably operated.
By combining Room-to-Room control and the Multi Source function, you can select an audio or video source as well as
adjust the volume level and tune in a broadcast station, all independently from a second room, even while the listener in
the main room is enjoying a different program source.
Remote Control Functions
Integral System (IS) Remote Control Unit
The DRA-775RD includes Integral System (IS) Remote Control and it commands not only the receiver but can also oper-
ate the main functions of a DENON CD player and a cassette deck when they are included in the system.
Multi Source Remote Control Unit
In addition to the Integral System Remote Control, the DRA-775RD comes with the Multi Source Remote Control Unit,
which operates the Multi Source Output and commands the receiver to select the function, tune the radio, and adjust
the volume level from a second room.
