Connecting the Unit

ENGLISH

Connecting the Speaker Wires

The speaker output mode can be two-channel (stereo) or one-channel (mono). Connect the

speaker leads to suit the mode according to the figures shown below.

• Do not connect both the RCA input and the speaker input at the same time.

• To ensure proper heat dissipation of the amplifier,

be sure of the following during installation.

—Allow adequate space above the amplifier for

proper ventilation.

—Do not cover the amplifier with a floor mat or

carpet.
