Inputs and Outputs Notes
Signal Level Divided Construction
Chassis Design: The circuit
handling low-level signals has been divided into separate blocks to ensure that
influences from these signals on each other are held to an absolute minimum.
This chassis design, known as the Signal Level Divided Construction (SLDC),
preserves the purity of the signal, allowing it to be reproduced with much
greater fidelity and clarity.
High-Quality Power Amplifier:
With 100 watts of power per channel (at 8 ohms, 20 Hz - 20 kHz, 0.05% THD), the
DRA-685 delivers solid, reliable audio performance even when driving both A and
B speaker systems at the same time.
Multi Source Function:
The DRA-685's Multi Source function lets you enjoy two different programs,
simultaneously in two or more areas of your home. You can listen to a CD or the
tuner in one room, for instance, while another family member watches a DVD video
or video tape in the other room. Dedicated multi-room outputs, with volume level
adjustment via remote control, are provided for connection to powered second
zone speakers or a second zone amplifier. The Multi Source output has left and
right RCA audio jacks and an RCA composite video jack.
Easy Simulcast Recording:
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.
Room-to-Room Remote Control with
Remote In/Out Terminals: External remote control equipment, including IR
re-transmitters and IR remote receivers, such as Denon's separately available
RC-616, RC-617S, RC-617W, and RC-618 IR devices, can be connected to the
DRA-685's IR remote input and output terminals. By connecting such equipment and
using the supplied sub room remote control, you can switch the sub room output
on and off, select the sub room source, adjust the volume, and recall preset
radio stations from the sub room.
Video Select Function:
This function allows you to select a
video source, and then select an alternate audio input source.
Record Out Selector: This
feature lets you listen to one source, while recording another source.
Last Function Memory:
This unit is equipped with a last function memory, which stores the input and
output setting conditions as they were immediately before the power was switched
The unit is also equipped with a back-up memory. This function provides
approximately one week of memory storage when the main unit's power switch is
off and the power cord is disconnected.
RC-872 Remote Control:
The main remote control can operate the
receiver as well as other remote control capable Denon components. In addition,
the remote is pre-programmed with control signals for other brands of products,
including DVD players, laserdisc players, VCRs, and TVs.
RC-873 Remote Control:
The sub room remote control allows you to switch the sub room output on and off,
select the sub room source, adjust the volume, and recall preset radio stations
from the sub room.
Inputs and Outputs Notes
All of the receiver's speaker terminals are binding posts. They are not 5-way
binding posts because a plastic collar prevents their use with spade lugs and
they are positioned too far apart to be used with dual banana plugs.
Room-to-Room Remote Jack:
The receiver has a minijack input for
use with an optional Denon RC-616 IR re-transmitter.
The receiver has a standard 1/4" headphone jack on the front panel for private
listening. When headphones are plugged in, the receiver's speaker and preamp
outputs are automatically turned off.
The left and right preamp outputs are connected to
left and right preamp inputs, respectively, with "U" shaped metal jumpers. The
jumpers may be removed to facilitate the connection of an equalizer or external
