ENGLISH

(2) Connecting the speaker terminals

* Read the amplifier’s operating instructions carefully before connecting, and be sure to use properly.

* When connecting the equipment or changing the connections, be sure to turn the equipment’s power

switches off and unplug the power plugs from the AC power outlets.

2 Connecting the speaker terminals

1. Peel off the sheath from the tip of the connection cord, then firmly twist the wires by hand so that they

do not stick out and cause short-circuits.

2. Loosen the terminal by turning it counterclockwise, then insert the connection cord into the hole in the

speaker terminal.

3. Turn the terminal clockwise to tighten it.

Check that none of the core wires are sticking out of the hole.

The red side is the “+” side, the black side the “–” side.

To “+” side on amplifier (copper colored core wire)

NOTE: Make sure the core wires do not touch each other.

To “–” side on amplifier (silver colored core wire)

Sheath

CAUTION:

• Be careful to interconnect the positive (“+”, red) and negative (“–”, black) sides and the left and right

speakers properly.

• Connect the side of the included connection cord with the copper colored core wires to the red speaker

terminal.

• To prevent circuit problems, never short-circuit copper and silver colored core wires or the left and right

cords.

Once the connections are completely, gently pull on the speaker cords to make sure they are securely

connected.

When installing, carefully examine the place and method of installation for safety.

When using a stand, brackets, etc., follow the instructions included with the stand or brackets and check for

safety before installing and using. Denon will accept no responsibility for damages or accidents caused by

the unit falling.

USING THE ACTIVE SUBWOOFER (DSW-3L)

1. Set the power switch to the “ON” position.

• When the unit’s AC power cord is plugged into a switched AC outlet on the amplifier, if the power switch

is left at the “ON” position, the unit’s power turns on and off automatically when the amplifier’s power is

turned on and off.

• If the AC power cord is not plugged into a switched AC outlet on the amplifier, set the unit’s power switch

to the “ON” position after turning on the amplifier’s power. When turning the power off, set the unit’s

power switch to the “OFF” position before turning off the amplifier’s power.

2. Adjust the volume using the volume adjustment control.

For details, see “PART NAMES AND FUNCTIONS”.

REMOVING THE SPEAKER NET (SC-A3L, SC-C3L)

* The net on the front of the speaker systems (SC-A3L, SC-C3L) can be removed.

• To remove, grasp both sides of the net and pull forward.

• To mount, line up the holes in the four corners of the speaker net with the projecting pieces in the four corners

of the cabinet and press in.
