■ Using a Euroblock connector

● Cable preparation

•To prepare the cable for attachment to a Euroblock 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.

approx.

7 mm

• If cables will be frequently connected and disconnected, as in the case of a portable installation, 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).

Be sure to use speakers that support the

XH200’s line-out voltage of 70V or 100V.

You cannot connect a low-impedance speaker directly to the XH200. In this case, be sure to use a speaker transformer (such as the Yamaha ST15). Follow the instruction guide that came with the speaker transformer to avoid excessive loads.

If you use stranded wire, do not tin (plate

with solder) the exposed end.

1 If the wire insertion ports are closed, turn the screws on

top of the connector counterclockwise to open the ports.

2 Insert the wires into the appropriate ports, following the

indication of the pole on the input terminal, turn the screws on top of the connector clockwise to ﬁx the wires.

3 Attach the Euroblock connector to the input terminal on

the unit.
