What you should know to protect
yourself
e Never touch the power cord's plug with wet hands.
e Always pullthe power cord out by its plug, never by its cord.
e Onlyletaqualified professional repair or reassemble the am-
plifier. An inexperienced person might touch the internal
parts and receive a serious shock.
e Never put anything, especially metal into the amplifier.
Protect the amplifier too
e Use a household AC power source only. Never use a DC
power source.
e If water is spilled on the amplifier, disconnect it and call your
dealer.
e Make sure that the amplifier is weil ventilated and away from
direct sunlight.
To avoid damage to the internal circuits and the external sur-
face, keep the amplifier away from heat (stoves, etc.).
e Avoid using aerosol sprays near the amplifier as this could
damage the finish or cause sudden ignition of the spray.
e Toavoiddamagingthe finish, never use paint thinner or other
similar chemicals to clean the amplifier.
e Place the amplifier on a flat and solid surface.
e Ifyou do notplan to use the amplifier for along period of time, -
disconnect the power cord.
Basic connections
Before connecting
e Turn off the power of all components before making conn-
nections. |
e Connect the power cord last.
e Make sure that you connect the white pin-plugs to the left (L-
white) terminals and the red pin-plugs to the right (R-red) ter-
minals. -
e Connect everything securely. Loose connections can lead to
distortion. |
e To prevent damage to the cords, connect and disconnect by
holding the plug, not the cord.
e [f your turntable is equipped with an earth wire, connect it se-
curely to the amplifiers 7747 terminal.
Speaker connection
Before connecting
e Check the impedance of your speakers.
When using one pair of speakers:
Connect speakers with an impedance of 4 to 16 ohms.
When using two pairs of speakers at the same time:
Connect speakers with an impedance of 8 to 16 ohms.
The amplifiers red speaker terminals are the ® (positive)
terminals and the black terminals are the © (negative) termi-
nals.
* The ® side of the speaker cable is marked to make it distin-
guishable from the © side of the cable. Connect this marked
side tothe red $ terminal and the unmarked side to the black
terminal.
e Prepare the speaker cords for connection by stripping off ap-
proximately 1cm or less (no more as this could cause a short
circuit) of the outer insulation.
How to connect
O Twist the wires together tightly.
O Turn the terminal cap counter-clockwise to loosen it.
The speaker terminal caps can not be fully removed from the
base. |
O Insert the wire into the terminal fully and turn the termi-
nal cap clock-wise to securely connect it.

Connecting hole Loosen
Speaker placement
‘The playback characteristics of the speakers are greatly in-
fluenced by the placement and the room in which the speakers
are used. To find the best location for the speakers play back
some music without using the tone controls and move the spea-
kers around. However please keep the following in mind:
e Place the speakers on a flat, solid surface which is free of vi-
bration.
e Place the speakers in an area that is well ventilated. Do not
place the speakers in a humid piace.
e Keepthe speakers away from direct suniight and heat sour-
ces (stoves, etc.).
e Keep the speakers away from the turntable.
To prevent damage to the speakers:
e Do not raise the volume excessively.
¢ Turn off the amplifier when connecting or disconnecting.
e Do not touch the speaker’s diaphragms.
Note:
e If the speakers are placed too close to the TV the magnetic
flux from the speakers will cause the TV screen to turn
slightly red or pink. To avoid this the speakers should be
placed a little distance from the TV.

Digital component connections (for AM-67 model
only)
Before proceeding
e Turn off the power of all components before making connec-
tions.
When connecting components to the DIGITAL 2 and 3 IN ter-
minals, use digital connection cords available from your
audio dealer.
If your DAT deckis equipped with optical input and output ter-
minals, connect it to the DIGITAL 1 (OPTICAL) IN and OUT
terminals of the amplifier using optical fibre cables.
Always replace the terminal caps of the DIGITAL 1 (OPTI-
CAL) IN and OUT terminals when a component is not con-
nected to them.
If your CD player is equipped with both an optical terminal
and analog outputterminals, we recommend that connection
oniy be made to the optical terminal for best sound reproduc-
tion.
The digital audio signal is a composite signal made up of the
left and right channel signais. For this reason, separate left
and right INPUT and OUTPUT terminals are not necessary.
DIGITAL 1 (OPTICAL) IN/OUT termi-
‘nals (AM-67 model only)
These terminals are for connection of CD players or or DAT decks
equipped with optical terminals.
Note:
e When you are not using the DIGITAL 1 OPTICAL) IN/OUT
terminals do not remove the terminal caps.

The protection circuit also functions during playback to pro-
tect the speakers from overloading and to protect the cir-
cuits from damage. |
When the protection circuit is engaged, the output signal
will be cut automatically.
Should the sound be cut during playback:
1 Turn the amplifier off.
2 Check for and correct the cause.
3 Turn the amplifier back on.
