Attaching Euroblock Plugs

Example (Connection to the [REMOTE] connector)
1
Loosen
Slotted screwdriver
Terminal
screw
Euroblock plug
NOTE
• You must use the supplied Euroblock plugs. If the plugs have been lost, please contact your Yamaha dealer.
• Use the 6-pin Euroblock plugs when connecting to the [INPUT] connectors 1-6.
• To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration using stranded wire to make
connections. With a Euroblock connection, stranded wires may be prone to breakage because of metal fatigue due to the weight of
the cable or due to vibration. When rack mounting your device, use a lacing bar when possible to bundle and fasten the cables.
• Do not tin (solder) the exposed end.

Connecting Speaker Cables

The [SPEAKERS] output connectors on the rear panel are barrier strip type connectors. The connections are described below for two
methods: using a spade lug and using a bare conductor.
Caution
• Ensure that load is not applied to the speaker cable.
• This device uses a BTL (Balanced Transformer-Less) connection method for the amplifier output. As the amplifier output is sent to the
positive and negative connectors, any contact with other terminals or the device chassis may lead to malfunction.
NOTE
Connect the cables so that the amplifier's "+" and "-" symbols match those of the speaker. If they are reversed, the phase will be
reversed and the sound will not be output correctly.
When using a spade lug
Loosen the screw, insert the spade lug all the way from below,
and tighten the screw.
