CONNECTIONS

Never plug the AC supply lead of this unit into the AC outlet until all connections are completed.

Connecting speakers

(See figure 6 on page 6.)

Connect the front speakers to the FRONT SPEAKERS terminals, the center speaker to the CENTER SPEAKERS terminals and the rear speakers to the REAR SPEAKERS terminals.

Note

Use speakers with the specified impedance shown on the rear of this unit.

■How to Connect:

Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is the + and – markings are observed. If these wires are reversed, the sound will be unnatural and lack bass.

Caution

Do not let the bare speaker wires touch each other as this could damage the amplifier and/or speakers.

Red: positive (+)

Black: negative (–)

Note on connecting a subwoofer (separate purchase)

You may wish to add a subwoofer to reinforce the bass frequencies.

Connect the SUBWOOFER OUT terminal of this unit to the INPUT terminal of the subwoofer amplifier, and connect the speaker terminals of the subwoofer amplifier to the subwoofer.

With some subwoofer systems, including the Yamaha Active Servo Processing Subwoofer System, an amplifier is incorporated into the system.

*The SUBWOOFER OUT terminal outputs low frequencies from the front and center channels.

(The cut-off frequency of signals output from this terminal is 200 Hz.)

■How to connect the YAMAHA NS-P30 speaker system (separate purchase) to this unit

(See figure 7 on page 7.)

If you connect the YAMAHA NS-P30 speaker system to this unit, read the following descriptions.

NX-E70 (Rear speakers)

cConnect the push-type input terminals on the rear of the speakers to the REAR SPEAKERS terminals of this unit with the provided speaker cables.

cOne side of the speaker cable has a white line and the other side has no line. Connect the (+) terminals on both this unit and the speakers using the side with a white line. Connect the (–) terminals on both components using the side with no line.

cConnect one speaker to the left (marked L) terminals of this unit, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, –). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass.

Procedures:

➀Press the tab on the terminal down, as shown in the

figure.

➁Insert the bare speaker wire end properly into the terminal hole. [Remove approx. 5 mm (1/4”) insulation from the speaker cable.]

➂Remove your finger from the tab to allow it to lock snugly on the cable’s wire end.

➃Test the security of the connection by tugging lightly on the cable at the terminal.

NX-C70 (Center speaker)

To connect the speaker cable from NX-C70 to the CENTER SPEAKERS terminals of this unit, make sure to connect the side with a white line to the (+) terminal and the side with no line to the (–) terminal.
