User manual DENON DRA-685

[. . . ] The Multi Room Music Entertainment System lets you set up an amp and speakers in a separate room, connect them to the DRA-685, and enjoy program sources independently of the listener in the main room. The remarkable DRA-685 deserves a close look and a listen as the best possible solution for your audio/video system needs. Multi Room Music Entertainment System / High-Quality Power Amplifier / Pure Current Power Supply / Radio Data System (RDS) 1 The First Name In Digital Audio DRA-685 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-685 is endowed with the same type of power supply circuitry as DENON'S best integrated amplifiers.

Pure Current Power Supply The DRA-685 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 suppress 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-685 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 eliminate interference. Frequency Synthesis Tuning RDS Tuning System The DRA-685 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. · Pre-Out, Main-In Jacks · Rec Out Selector · 3-Way Speaker Terminals · Loudness Switch · Bass & Treble control · Tone defeat Switch · Muting Switch (Remote only) Multi Room Music Entertainment System Multi Source Function The DRA-685'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 considerable flexibility when setting up and enjoying your system with the DRA-685. 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-685 can be used in configuring a room-toroom remote control system by adding the optional RC-616/617S/617W/618. And because direct terminals for the RC616 (IF Re-transmitter) are provided on the DRA-685, 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-685 includes Integral System (IS) Remote Control and it commands not only the receiver but can also operate 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-685 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.
