Through (RCA2)
(RCA2>***)
You can select whether to use the RCA 2 connectors as normal input
connectors or as signal through connectors.
The default setting is "NML".
NML (normal)
Select this to use the RCA 2 connectors as normal input connectors.
THRU (through)
The volume level adjusted using the VOLUME knob is ignored
when this setting is selected. Sound signals passing through the
RCA 2 connectors are output as they are. (No gain adjustment is
made by the preamplifier.)
After selecting "THRU", press the STANDBY/ON (setting) button to
activate the setting.
"THRU" appears on the display instead of the volume level set by
using the VOLUME knob.
For example, if you connect the pre-out connectors (FRONT L/R)
of an AV amplifier to this unit's RCA 2 connectors, and set RCA2 to
"THRU", you can also use the speakers connected through this unit
as the front speakers of the AV amplifier. (The AV amplifier controls
volume adjustment when the input source is set to "RCA2".)
o If through output (RCA2) is set to THRU and the input source is
RCA 2, the VOLUME knob will not function.
V Since this unit's VOLUME knob will not function when set
to "THRU", be careful if you connect a device that does
not have a volume control to the RCA 2 input connectors.
When you change the input source to RCA2, very loud
sounds could be output suddenly, resulting in harm to
your hearing and damage to the speakers.
When connecting a device that does not have a volume
control to the RCA 2 input connectors and setting RCA2
to "THRU", always connect a device that has a volume
control to this unit's analog output connectors (LINE
OUT). Use that device to minimize the volume before
switching the input source to RCA2, and then gradually
raise the volume level.
Illumination
(Light>***)
You can set whether or not the rings of the knobs light.
The default setting is "AUTO".
AUTO
When the knobs are operated, their rings light.
ON
The rings around the knobs will stay lit.
OFF
The rings around the knobs do not light.
