Rear panel facilities and connections
Unbalanced Input (single end RCA input)
Connect controllers or pre-amplifiers with single-ended
outputs for high-quality sound.
Note:
• When using this single-ended connection for a
specific channel between the pre-amplifier and
RDA-7, set the INPUT SELECT switch to the RCA input
side to select single-ended input. Next, use high-
quality cables and connect the single-ended output
from the pre-amplifier to the corresponding single-
ended input on the RDA-7.
• Do not connect anything to the balanced input jack.
Note:
• When using this balanced connection for a specific
channel between the pre-amplifier and RDA-7, set
the INPUT SELECT switch to the XLR input side to select
balanced input. Next, use high-quality cables and
connect the balanced output from the pre-amplifier
to the corresponding balanced input on the RDA-7.
• Do not connect anything to the RCA-type audio
input jack.
The pin assignments for this terminal are given above.
This pin assignment conforms to the standard adopted
by the Audio Engineering Society. Refer to the
instruction manual supplied with the pre-amplifier and
verify that its output terminal is compatible with the pin
assignments for this terminal. If it does not, wire it so that
the output pins connect with the proper input pins.
Connector ground terminal: Chassis grounded
2. Disconnecting the input terminal
Pull out the connection cord while holding down the lever.
Balanced Input (XLR terminal)
Connect controllers or pre-amplifiers with balanced
outputs for high-quality sound.
Precaution for connection
This unit comprises 7 independent power amplifiers,
each being capable of reproducing the same quality
sound through its channel. Note that you should
connect an input source and a speaker to each
channel in use. For channels that are not in use, we
recommend that you do not connect any input source
or speaker.
