External pre playback
How to connect between the external pre-
input terminals and an input device such
as an AV amplifier
When using this unit with the external pre-input, only the
unbalanced output terminal is enabled. Therefore, no sound
will be generated if connecting an input device to the balanced
input terminal.
In a state where the main power is off or in a standby state,
external pre-input signals will always be output from the
unbalanced output terminals regardless of whether the exter-
nal pre button is on or off.
Connect between the pre-output terminals of an input device
such as an AV amplifier or pre-amplifier and the external pre-
input terminals of this unit with pin-plug cables.
Take extra care not to incorrectly connect between right and left
channels. If the right and left channels are connected reversely,
the localization of sound images will deteriorate, thus failing in
normal stereo playback.
Also, inadequate connection of the grounding of the pin-plug
cables may generate noise including a hum, resulting in an
adverse S/N ratio. Carefully insert the connection plug correctly.
When the external pre button is on, sound volume adjustment
cannot be made with the volume control of this unit. Adjust
the sound volume on the input device side such as the AV
amplifier or pre-amplifier connected to the external pre-input
terminal.
When a device such as a CD player that the sound volume
adjustment does not function is connected to the external
pre-input terminal, the sound volume adjustment of the
device cannot be controlled by the volume control of this unit.
Therefore, switching the selection to the external pre-input will
produce a sudden loud sound and it may result in a hearing
impairment or damage of the speakers.
For such input devices, be sure to use a pre-amplifier
equipped with volume adjustment, begin feeding audio to the
speakers with the volume low and adjust the volume to your
preferred level.
