Speaker A/B connection

This unit is equipped with two sets of speaker terminals (SPEAKER A and SPEAKER B). One set of speakers can be connected to each set of terminals,

and a total of two sets of speakers can be connected.

The same signal is output from the SPEAKERS A and SPEAKERS B terminals.

When only one set of speakers is to be connected, use either the SPEAKERS A or SPEAKERS B terminals.

Bi-wiring connection

This connection limits the effects of signal interference between the high range speakers (tweeters) and low range speakers (woofers), allowing you to

enjoy high quality playback.

When bi-wiring with bi-wireable speakers, connect the mid and high range terminals to SPEAKERS B (or SPEAKERS A), the low range terminals to

SPEAKERS A (or SPEAKERS B).

Connecting a playback device

You can connect turntables, tuners, Blu-ray disc players, network audio players and CD players to this unit.

This unit is compatible with turntables equipped with a moving magnet (MM) phono cartridge. When you connect to a turntable with a low output moving

coil (MC) cartridge, use a commercially available MC head amp or a step-up transformer.

If you set this unit’s input source to “PHONO” and you accidentally increase the volume without having a turntable connected, you may hear a hum noise

from the speakers.

NOTE

0The earth terminal (SIGNAL GND) of this unit is not

for safety grounding purposes. If this terminal is

connected when there is a lot of noise, the noise can

be reduced. Note that depending on the turntable,

connecting the ground line may have the reverse

effect of increasing noise. In this case, it is not

necessary to connect the ground line.

0The PHONO input terminals are equipped with a

short pin-plug. Remove this plug to connect a record

player. Store the removed short pin-plug in a safe
