Connecting to the Amplifier

1

Connect the MD-101A to the MD (or TAPE)

jacks of your amplifier.

2

Connecting to the Digital Input
Terminals (DIGITAL INPUT 1, 2)

You can perform digital recording on the MD­101A if a CD (Compact Disc) player or DAT
(Digital Audio Tape) deck equipped with a digital
(OPTICAL) output terminal is available. For digital
recording, you need to connect the equipment
to either DIGITAL INPUT 1 or 2 terminal using
the supplied optical cable.
These terminals can also
be used for connecting an
amplifier that is equipped
with a digital output
terminal.

Note

If you use DIGITAL INPUT 2 to connect an
amplifier, you will be unable to utilize the full
capabilities of the MD-101A.
If you attempt to perform digital recording using
a digital input terminal that is not connected,
"D.In Unlock " will appear.

Terminal protection caps are attached to the
DIGITAL INPUT terminals. Remove the cap for the
terminal you wish to use when connecting the
MD-101A to digital equipment. Replace the caps
if you are not using the DIGITAL INPUT terminals.

Connection to AC outlet
(UNSWITCHED)

The power cord of another unit can be connected
to this outlet.

Note

The shape, number, and total capacity of the AC
outlets may differ depending on the area in which
the unit is purchased.
230-240 V, 50/60 Hz model: Capacity is 100 W in
total.

[Note]
Do the work to (5)-(7) within 15 seconds.
Since continuation luminescence of the 7mW laser power is carried out, if it is left for a long time,
the pickup will deteriorate.
