Connecting an external power amplifier

When connecting an external power amplifier (pre-main amplifier) to enhance speaker output, connect the input jacks of the power amplifier to the PRE OUT jacks of the unit.

The same channel signals are output from the PRE OUT jacks as from their corresponding SPEAKERS terminals.

NOTICE

To prevent the generation of loud noises or abnormal sounds, make sure the followings before making connections.

  • Unplug the power cable of the unit and turn off the external power amplifier before connecting them.
  • When using the PRE OUT jacks, do not connect speakers to the corresponding SPEAKERS terminals.
  • When using a pre-main amplifier that does not have the volume control bypass, turn up the volume of the pre-main amplifier enough and fix it. In this case, do not connect other devices (except the unit) to the pre-main amplifier.

a

FRONT jacks

Outputs front left and right channel sounds.

b

SURROUND jacks

Outputs surround left and right channel sounds.

c

SUR. BACK jacks

Outputs surround back left and right channel sounds.

Under some speaker settings in “Power Amp Assign” in the “Setup” menu, the unit outputs no sounds from these PRE OUT jacks.

d

CENTER jack

Outputs center channel sounds.

e

F.PRESENCE jacks

Outputs front presence left and right channel sounds.

f

R.PRESENCE jacks

Outputs rear presence left and right channel sounds.

Under some speaker settings in “Power Amp Assign” in the “Setup” menu, the unit outputs no sounds from these PRE OUT jacks.

g

FRONT (XLR) jacks

Outputs front left and right channel sounds through XLR balanced cables.

NOTE
  • Use XLR balanced cables to connect a power amplifier to the FRONT (XLR) jacks on the unit.
  • Before connecting an XLR balanced cable, refer to the instruction manual of your device and verify that its XLR jacks are compatible with the pin assignments.
  • For XLR output jacks, match the pins and insert the “female” plug of the XLR balanced cable until you hear a click. When disconnecting the cable from the unit, hold down the lever of the plug and then pull it out.
  • We recommend using power amplifiers with volume control bypass (or without volume control circuit).
  • When you set the following speaker settings in “Power Amp Assign” in the “Setup” menu, some outputs from the PRE OUT jacks are limited.
