AM/FM Stereo Receiver

DRA-685
Superb Stereo Sound and Multi-room Entertainment Convenience
Featuring a multi-room audio function, along with video selection and high power, the DRA-685 serves as the heart of a stereo music system while providing stereo sound for stereo video sources. With a prodigious 100 watts of power per channel, the DRA-685 can easily drive virtually any modern loudspeaker system with authority and clarity. A full suite of convenience and switching functions makes the DRA-685 an indispensable choice for a well equipped music system.
Signal Level Divided Construction (SLDC) The circuit 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-685 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.
Second Zone Remote Controller (RC-873) In addition to the main remote, the DRA-685 is also supplied with another remote that is customized for the second zone mutli-room functions. It is equipped with second zone source selection, recalling preset radio stations, adjusting the volume, and other functions that can be controlled from the second zone room.
High-Quality Power Amplifier Section 100 W + 100 W (8 ohms, 20 Hz - 20 kHz, 0.05 %) Providing 100 watts per channel, into 8 ohms, from 20 Hz to 20 kHz, with no more than.05% total harmonic distortion, the DRA-685 provides separates class audio performance. Together, these components provide superb low impedance drive capability with tremendous dynamic reserve capacity. High speed, wideband discrete power transistors provide delicacy and impact, ideally suited to the needs of the highest quality analog and digital sources.

Multi Source Function The DRA-685s Multi Source function lets you enjoy two different programs in two different rooms. For example, listen to the CD player in the main room, while another family member listens to the tuner in another room in the home. Dedicated multi-room output jacks, with variable volume level adjustment via remote control, are for connection to powered second zone speakers or a second zone amplifier.

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. Record Out Selector Lets you listen to one source (example: Tuner), while recording another source (example: CD). Ideal for making unattended tape copies.
Sophisticated Tuning Circuit Design Thanks to the PLL circuit design, reception drift is a thing of the past. The DRA-685 also has a 4-pole varactor diode in its front end to guarantee accurate input of station frequencies. Auto scanning of radio frequency bands Fast up/down manual tuning Manual step tuning Last-channel-tuned memory

Video Terminals Stereo video sources, such as hi-fi VCR, stereo TV, and DVD can all be easily connected to the DRA-685s VDP, VCR and Video Aux terminals. Video Select Function Allows you to select a video source, and then select an alternate audio input source, ideal for simulcasting, as well as watching TV sports programs while listening to radio commmentary. 40-Station AM/FM Random Preset Memory Tuning
