■ [MONO INPUT] and [OUTPUT] Con-
nectors (3-pin Euroblock)
Connect external microphones, amplifiers and other devices to
the rear-panel [MONO INPUT] and [OUTPUT] connectors via
cables fitted with the supplied 3-pin Euroblock plugs.
Follow the procedure outlined in this section to attach the Eurob-
lock plugs to the appropriate cables.
Use balanced lines to connect microphones and similar sources
to the [MONO INPUT] connectors. Wire balanced cables as
shown in the diagram below.
When an amplifier to be connected to the OUTPUT connector
has balanced XLR type inputs, wire the connection cable as
shown in the diagram below.
Euroblock Plug Connection
Use the included Euroblock plug (3P) to make connections to the
[MONO INPUT] and [OUTPUT] connectors.
1 Loosen the terminal screws.
NOTE
•A “minus” type screwdriver with a blade width of approxi-
mately 3 millimeters is recommended for Euroblock connec-
tor attachment.
2 Insert the cables.

● Cable preparation
•To prepare the cable for
attachment to a Eurob-
lock connector, strip the
wire as shown in the
illustration, and use
stranded wire to make
connections. With a Euroblock connection, the stranded
wire may be prone to breakage because of metal fatigue
due to the weight of the cable or due to vibration. When
rack-mounting your equipment, use a lacing bar when
possible to bundle and fasten the cables.
• If cables will be fre-
quently connected and
disconnected, as in the
case of a portable instal-
lation, we recommend
that you use ferrules with
insulation sleeves. Use a
ferrule whose conductor
portion has an external diameter of 1.6 mm or less, and a
length of approximately 7 mm (such as the AI0,5-6WH
made by the Phoenix Contact corporation).
CAUTION
• If you use stranded wire, do not tin (plate with solder) the
exposed end.
