Hooking Up the Components
Notes on speaker system hookup
• Twist the stripped ends of the speaker cords about 10
mm.
• Connect the right front and rear speakers to the FRONT
and REAR SPEAKERS “R” terminals, connect the left
front and rear speakers to the FRONT and REAR
SPEAKERS “L” terminals.
Be sure to match the speaker cord to the appropriate
terminal on the components: + to + and – to –. If the
cords are reversed, the sound will be distorted and will
lack bass.
• If you use front speakers that have a low maximum
input rating, adjust the volume of the control amplifier
carefully to avoid producing excessive output from this
unit that may be harmful to the speakers.
• To obtain a higher power output when using speakers
with a nominal impedance greater than 8 ohms, connect
the speakers using BTL connections.
When making BTL connections, refer to “BTL
Connections Using Two Power Amplifiers” on page 10
for details.
• Set the SPEAKER IMPEDANCE selector on the rear
panel according to the type of speakers you are
connecting. See “Selecting the speaker impedance” on
this page for details.
• When making normal (non-BTL) connections to your
speakers, be sure the OPERATION selector on the rear
panel of the power amplifier is set to “NORMAL”.
When making BTL connections, set to “BTL”.
Selecting the speaker impedance
Be sure to set the SPEAKER IMPEDANCE selector on the
rear panel of the power amplifier to the top position when
making normal connections to speakers with nominal
impedance of 4 to 8 ohms, or when making BTL
connections to speakers with nominal impedance of 8 to
16 ohms.
Set the SPEAKER IMPEDANCE selector on the rear panel
of the power amplifier to the bottom position when
making normal connections to speakers with a nominal
impedance greater than 8 ohms, or making BTL
connections to speakers with a nominal impedance
greater than 16 ohms.
Setting the selector to the top position will decrease the
power amplifier’s maximum output.
Note
Be sure to the power amplifier is turned off before you change the
position of the SPEAKER IMPEDANCE selector.
speaker cord
This is a high output amplifier. Touching the stripped
end of the speaker cords may result in injury.
When connecting the speakers, be sure the stripped
end of the speakers cord does not protrude from the
speaker terminal.
