7. CONNECTIONS

1.Switch off the amplifier power.

2.Unscrew the output terminal cover.

3.Strip 10 mm of insulative jacket from the end of the speaker cable, as shown in the figure at right.

4.Connect speaker cables to the output terminals.

5.Fit the output terminal cover in place.

[Precautions] Be sure to fit the output terminal cover in place.

Take care that the naked wires of the speaker lines do not contact the unit's chassis.

Refer to the figures below for connections for each output mode.

Since the upper output terminals are connected in parallel with the lower terminals, both terminals can be used simultaneously.

STEREO mode

Output mode switch Output terminal

BTL mode

Output mode switch Output terminal

PARALLEL mode

Output mode switch Output terminal

[Precautions]

The total impedance of the connected speakers must be over 4 (STEREO and PARALLEL modes) or over 8 (BTL mode). If the impedance of the connected speakers is smaller than those stated above, equipment failures may result.

Refer to the table below when using an optional output transformer.

Power amplifier Output transformer(option)

IP-600DMT-600M

IP-450DMT-450M

IP-300DMT-300M

[Precautions]

Do not connect the output transformer under any circumstances when in BTL mode. Both the amplifier and transformer may fail.
