Rear panel facilities and connections

Fuse

The RDA-7 uses a 250V AC slow-blow (time lag) main
fuse. To replace the fuse, insert a coin or similar object
into the groove, turn it to the left, and remove the fuse.
Replace only with the same type and same rating. The
correct fuse rating will differ depending on the voltage
of your set as given here.

120V:T15A/250V

220V/230V/240V:T10A/250V

AC INLET

Plug the supplied Power cord into this AC INLET and then
into the Power outlet on the wall,

Caution

• Do not connect any devices other than speakers to

these terminals. Also, never short-circuit the output
from these terminals.

• Be sure not to mistake the positive and negative

outputs or the left and right speakers. Doing so will
result in an unnatural sound space.

• Only connect speakers with an impedance of 4

ohms or greater. If a speaker with an impedance of
less than 4 ohms is connected, it may damage the
RDA-7.

• Do not connect more than one speaker cable to

one output terminal. Doing may damage the RDA-7.

Be sure to read “Phasing your speaker system” and
“Speaker ratings” on the following page.

Do not use a Power cord other than the one supplied
with the RDA-7. The Power cord supplied is designed
for use with the RDA-7 and should not be used with
any other device.

Never have the Power cord disconnected from the
RDA-7 while the other end is plugged into the wall
outlet. Doing so may cause an electric shock. Always
connect by plugging into the wall outlet last and
disconnect by unplugging from the wall outlet first.

Ground

If connecting the unit to another equipment causes
noise such as a hum, you may improve the reproduced
sound quality by connecting this terminal to the
grounding terminal of the connected equipment with a
lead wire.

Warning

Before replacing the fuse or making any electrical
connections, always turn off the Power and disconnect
the Power cord.

12V TRIGGER IN/OUT

Connect the 12V TRIGGER IN jack to control amplifiers
that have a 12V TRIGGER output jack, such as the RDC-
7. This jacks works on between 5 to 12 volts DC. With the
Power switch of the RDA-7 set to On, you can switch the
RDA-7 between the on and Standby states with
operations at the control amplifier.

If you want another component to be activated by
turning on and off the control amplifier connected to
the 12V TRIGGER IN jack of the RDA-7, then connect the
12V TRIGGER input jack of that component to the 12V
TRIGGER OUT jack of the RDA-7. In this state, even if the
RDA-7 is turned off, the signal from the control amplifier
passes through the RDA-7 and goes out the 12V
TRIGGER OUT jack. Daisy chaining is also possible using
these jacks.

Use 

φ

3.5-mm (1/8-inch) monaural-type mini-jack

connectors. The tip polarity of the connectors are as
shown below.

1. Strip away 15 mm (5/8 inch) of wire insulation.

2. Twist wire ends very tight.

3. Unscrew

4. Insert wire

5. Screw

+ OUTPUT –

(Speaker output and binding post)

The RDA-7 is equipped with high-current binding posts
for use at output terminals to the speaker system. To
obtain the best in sound quality from the RDA-7, we
recommend the use of high-quality speaker cables.

For each channel, connect the negative (or black)
output post to the negative (or black) input terminal of
the speaker and the positive (or red) output post to the
positive (or red) input terminal of the speaker.

Make the connections following the procedure given
below.

• Make sure that connections have been made only

to the inputs selected with the INPUT SELECT switches
and nothing is connected to the other ones.
