NOTE:
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

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. You can connect
banana plugs, too. The terminals can be used for bi-wiring
connection, also, using both types of plugs mentioned above.
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.)

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.
