DRA-375RD
DRA-275R
Affordable Receivers with uncompromised
DENON Quality.
The DRA-375RD and DRA-275R are DENON's latest receivers in the affordable class.
The DRA-375RD features the Radio Data System (RDS) reception capability, and the
DRA-275R now comes equipped with several features that had previously been available
only in the higher-end version, such as Character Input, Auto Preset Memory, AM/FM
40-Station Random Preset, and Video and VCR terminals including two video inputs.

Signal Level Divided Construction (SLDC)
The circuits handling low-level and high-level signals have been divided into separate blocks to ensure that influences from these signals on each
other are held to an absolute minimum. This new chassis design in the DRA-375RD/275R is called the Signal Level Divided Construction (SLDC).
Signals for output are cleaner than before, allowing them to be reproduced with even greater fidelity and clarity.
High-Quality Power Amplifier Stage
Powerful high-speed transistors are used in a rational circuit configuration, reflecting DENON's advanced amplifier technology, to deliver a hefty,
stable power output.
Two Sets of Video Inputs and Outputs
A new feature on a DENON receiver is the provision of video input and output terminals for you to connect a video device, such as a VCR or TV
monitor. The DRA-375RD and DRA-275R include two sets of video input and output terminals (VCR, Video inputs and VCR, Monitor outputs).
Adjustable Loudness
Both of these receivers include a Variable Loudness equalization control which lets you select the most appropriate loudness setting at any volume.
Electronic Source Selection
Advanced electronic switches located close to the input terminals have replaced source selector-to-jack cables to further
reduce sound quality deterioration.
Last Function Memory
When you turn off the power to either the DRA- 375RD or DRA-275R, the receiver automatically memorizes the settings, preserving the same
condition for when you turn the receiver back on again.
3-Way Speaker Terminal
The speaker terminals on these receivers can accommodate banana plugs, spade plugs, or bare wire wrapping.

Switchable AC outlets
Precision Tuning
Radio Data System (RDS)
The DRA-375RD tuner features RDS, the new FM broadcasting system that is becoming increasingly popular in Europe and the United States.
Tuners with RDS reception capability are able perform a wide range of services for the listener.
• Program Service Name (PS)
The name of the station being received is shown on an 8-character display.
• Program Type (PTY)
PTY lets you select from among 22 types of music and programs you want to listen to : Country, Jazz, Rock, Classical, Top 40, News, Sports, Talk,
National Public Radio, and so on. A station broadcasting the type of program specified is then automatically tuned in.
• Radio Text (RT)
RT displays onto screen a message of up to 64 characters that the station is currently transmitting.
• Traffic Program Identification (TP)
When TP is active, it automatically tunes to a station which is about to broadcast traffic information.
• Traffic Announcement Identification (TA)
A "TA" indication is displayed if the station being received also provides traffic information.
• Clock Time (CT)
CT lets you display the current time or make easy clock adjustments between daylight savings and standard time.

40-Station Random Preset Memory
Up to 40 FM or AM stations can be stored in random order in a memory that is partitioned into five groups - A, B, C, D and E.
Auto Preset Memory (FM only)
A maximum of 40 FM stations can be received by the tuner and automatically stored into the preset memory when you do not know the
frequencies of local stations.
Character Input
The Character Input feature lets you enter up to 8 characters for each preset station for easier station identification during tuning.
Large FL Display
The large fluorescent display clearly shows the reception frequency and the preset channel number as well as other information.
FL Tuning Indicator
When a station is currently tuned in, the "TUNED" indicator lights up. The DRA-375RD/275R can also be precisely tuned manually.
Last Function Memory
When you turn off the power to either the DRA- 375RD or DRA-275R, the receiver automatically memorizes the settings, preserving the same
condition for when you turn the receiver back on again.
Other Special Features
Integrated Remote Control
The DRA-375RD and DRA-275R receivers are endowed with the Integral System (IS) remote control capability. This means that with the same
remote control unit you can also operate any DENON CD player or DENON cassette deck that you have connected to your DENON receiver.
