Precautions for use

o These units are very heavy, so take care to avoid injury during

installation.

o Do not install these units in locations that could become hot.

This includes places that are exposed to direct sunlight or near a

radiator, heater, stove or other heating equipment. Moreover, do

not place them on top of another amplifier or equipment that

generates heat.

o Avoid locations that are subject to vibrations or exposed to

excessive dust, cold or moisture.

o In order to enable good heat dissipation, leave at least 20 cm

(8”) between these units and walls and other equipment when

installing them.

If you put them in a rack, take precautions to prevent overheating

by leaving at least 5 cm (2”) open above the tops of the units and

at least 10 cm (4”) open behind them.

o Do not install them face up or on their sides.

o Place each unit in a stable location near the audio system that

you will use with it.

o Do not place anything, not even CDs, CD-Rs, LP records or cas-

sette tapes, on top of the units.

o Do not put cloth on top of the units or place them on top of bed-

ding or thick carpet.

o Supply voltage to the power unit that matches the voltage indi-

cated on the rear panel. If you are in any doubt regarding this

matter, consult an electrician.

o Do not move the units during use.

o Do not open the bodies of the units as doing so might result in

damage to the circuitry or cause electric shock. If a foreign object

should get into one of the units, contact your dealer.

o When removing each power plug from an outlet, always pull

directly on the plug. Never pull on the cord itself.

o If a TV is turned on while the unit is on, static might appear on

the TV screen depending on the characteristics of the TV broad-

cast signal. This is not a malfunction of the unit nor of the TV. If

this occurs, turn the unit off.

Note about pinpoint feet

High-precision metal pinpoint feet are attached firmly to the bottom

plates of these units.

The stands for these feet are loose, but when a unit is placed in posi-

tion, it is supported by these pinpoint feet, which will effectively

disperse vibrations.

Through (Thru) output setting (RCA 2)

RCA2>***

You can select whether to use the RCA 2 jacks as normal input con-

nectors or as signal through connectors.

The default setting is “NML”.

NML (normal)

Select this to use the RCA 2 jacks 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

jacks 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 jacks (FRONT L/R) of an

AV amplifier to this unit’s RCA 2 jacks, and set RCA2 to “THRU”, you

can also use the speakers connected through this unit as the front

speakers of the AV amplifier. (When set to “RCA2”, the AV amplifier

controls volume adjustment.)

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 inputs. 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 inputs 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.
