WARNING
The unit is not disconnected from the mains as long as it is connected to
the AC outlet, even if the unit itself has been turned off.
To reduce the risk of fire, do not cover the ventilation opening of the
appliance with newspapers, tablecloths, curtains, etc.
Do not expose the appliance to naked flame sources (for example, lighted
candles).
To reduce the risk of fire or electric shock, do not expose this appliance to
dripping or splashing, and do not place objects filled with liquids, such as
vases, on the appliance.
As the main plug is used to disconnect the unit from the mains, connect
the unit to an easily accessible AC outlet. Should you notice an abnormality
in the unit, disconnect the main plug from the AC outlet immediately.
Do not install the appliance in a confined space, such as a bookcase or
built-in cabinet.
Do not expose batteries or appliances with battery-installed to excessive
heat, such as sunshine and fire.
Excessive sound pressure from earphones and headphones can cause
hearing loss.
Indoor use only.
This symbol is intended to alert the user to the presence
of the Hot Surface that may be hot if it is touched during
the normal operation.

Main features of the amplifier
Discrete amplifier for exclusive use with
headphones
Power amplifier utilizing single push-pull output
This power amplifier achieves dynamic output by using a single pushpull amplifier.
The power amplifying stage, which determines sound quality, consists
of a single pair of transistors, successfully eliminating the emitter
resistance used by conventional amplifiers to suppress overheating.
The transistor output drives the speaker directly, reproducing sound
with less undesired character.
Frame beam base chassis (FBB chassis)
A frame beam base chassis has been developed for the stereo
amplifier.
By combining a conventional frame beam chassis with a transformer
base, providing high accuracy and stiffness, the frame is more
stabilized, reproducing better sound with less overall distortion.
A preamplifier constructed of completely discrete
stages
This amplifier employs a relay for signal switching to eliminate sound
loss, and discrete circuits for entire stages to optimize and upgrade
the circuits.
Newly-designed large speaker terminals
The terminals of this amplifier minimize sound quality deterioration.
Y-lugs and speaker wires can be tied securely.
This amplifier has a discrete amplifier used exclusively to drive
headphones. The impedance can be switched among LOW, MID, or HI
to match that of the headphones.

Getting started
SPEAKER IMPEDANCE switch
Connecting speakers
Connect your speakers to the amplifier.
Before connecting speakers, make sure that you disconnect the AC
power cord (mains lead).
Use a speaker cord (not supplied) to connect the speaker terminals.
Speaker cord (not supplied)
Notes on speaker connections
Connect the left speaker to the SPEAKER (LEFT) terminals and the
right speaker to the SPEAKER (RIGHT) terminals.
Be sure to connect the speaker cords between the speakers and the
amplifier with the same polarities (plus (+) to plus (+), minus (–) to
minus (–)). By paying attention to the color or mark of the speaker
cord to be connected to the plus (+) or minus (–) connector, you can
always be sure of connecting the cord correctly without mistaking
plus or minus.
Be careful not to touch the amplifier body or other jacks with the
ends of the speaker cable. Doing so may cause short circuits, etc.,
resulting in a malfunction of the amplifier.
Setting the speaker impedance
Be sure to turn the power off before setting the SPEAKER
IMPEDANCE switch. When it is on, the switch does not work.
When you connect speakers with a nominal impedance of 8 ohms or
higher, set the SPEAKER IMPEDANCE switch to “8 Ω.” When
connecting other types of speakers, set it to “4 Ω.”
If you are not sure of the impedances of the speakers, refer to the
operating instructions supplied with your speakers. (This information
is often on the back of the speaker.)

Align.
Press here to disconnect.
You can connect equipment with analog audio jacks, such as a Super
Audio CD player or CD player, to the amplifier.
The amplifier does not support phono inputs.
Before connecting audio equipment, make sure that you disconnect
the AC power cord (mains lead).
Use an audio cable (not supplied) or an XLR (balanced) cable (not
supplied) to connect equipment to the analog audio output jacks.
Audio cable (not supplied)
Connect the white plug to the L jack and the red plug to the R jack.
XLR (balanced) cable (not supplied)
Notes
Since the XLR (balanced) cable is locked, you cannot disconnect the cable
by pulling it.
If you carry the amplifier or audio equipment with the cable connected, it
might be damaged. Make sure that you disconnect the cables before
carrying it.
Connect the cables firmly and securely. Otherwise, noise may be result.

Analog audio output jacks of Super Audio CD player, CD player, Network player, etc.
• This amplifier does not support phono inputs.
• It is not necessary to connect all the cables.
• Connect cables according to the jacks of your equipment.
Tip
If you connect the amplifier to a Sony product with an IR repeater output

Some space is left between the plug
and the rear panel even when the AC
power cord (mains lead) is inserted
firmly. The cord is supposed to be
connected this way. This is not a
malfunction.
control
Connecting the AC power cord (mains lead)
Connect the supplied AC power cord (mains lead) to the AC IN terminal
on the amplifier firmly, then connect the AC power cord (mains lead)
to a wall outlet.
Notes
Before connecting speakers and audio equipment, make sure that you
disconnect the AC power cord (mains lead).
Do not connect the AC power cord (mains lead) until all connections are
completed.
Plug in the AC power cord (mains lead) securely. A poor connection may
cause unstable operations.
Turning on the amplifier
Press to turn on the amplifier.
You can also turn on the amplifier using on the remote control.
When you turn off the amplifier, press again.
When the amplifier is on, the indicator is lit in green.
When there is something wrong with the amplifier, it lights up in red.
Check for a short circuit of the speaker output, or a short circuit of the
headphone output. Remove the causes and turn on the amplifier
again.
