Connecting the Unit
Connecting the Speaker Wires
Connect the speaker leads and set MODE SELECT switch and POWER MODE switch to suit the configuration according to the figures shown below and the next page. � When synchronously connecting two or more amplifiers in combination, only use these amplifiers. Do not mix these amplifiers with other amplifiers. � When synchronously connecting two or more amplifiers in combination, set the gain control, subsonic select switch, cut off frequency control for LPF and bass boost control on the amplifier that has been set to MASTER with the MODE SELECT switch. These settings are inactive when set on an amplifier set to SYNC or SYNC INV. 2 � to 16 �

2� Speaker � Only use speakers having an impedance of 2 � to 16 �. In addition, in the case of connecting multiple speakers with a bridge, check that the synthetic impedance is at least 2 �. � The setting of the POWER MODE switch varies according to the speaker impedance. Slide the POWER MODE switch to the HI-CURRENT position if the impedance is from 2 � to less than 4 �, or slide it to the NORMAL position if the impedance is from 4 � to 16 �. The same setting is used for both amplifiers. � When switching to the SYNC INV mode, the seal over the MODE SELECT switch must be peeled off and

Do NOT install or use this amplifier by wiring speakers rated at 2 � (or lower) in parallel to achieve a 1 � (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result. To properly install or use a bridged mode and achieve a 2 � load, wire two 4 � speakers in parallel with Left + and Right � (Diagram A) or use a single 2 � speaker. If the synthetic impedance is from 2 � to less than 4 �, always make sure to set the POWER MODE switch to the HI-CURRENT position. In addition, refer to the speaker instruction manual for information on the correct connection procedure.
