• Connect a wire from the ground terminal on the rear panel of this unit, to the ground terminal on the
applicable source unit (or any other point on the cabinet where noise can be brought down to a minimum).
However, absolutely ensure the wire does not touch any areas related to the power source such as auxiliary
AC outlets, and do not insert the wire inside the cabinet.
• Contact your dealer for further advice.
STEREO AND MONO OPERATION
The power amplifier can be used either as a normal stereo or as a bridged mono amplifier. The unit comes
factory-set as a stereo amplifier (the BRIDGED switch on the back of the unit is set at the STEREO position). Do
not tamper with the switch, unless you wish to use the unit as a mono amplifier, in which case reset the switch to
the MONO position. Do not connect the speakers before the switch position is set correctly according to your
choice. Two bridged mono amplifiers must be used for stereo operation.
MAKING THE CONNECTIONS_
See Illustration 1 - Rear Panel, to visualize where the connections to components are to be made.
1. CONNECTING THE SPEAKERS:
• The illustration shows what audio components you can connect to the rear panel of the unit and how they
should be properly hooked up via RCA type pin cords. Ensure that the Left and Right channels are correctly
matched between the RCA type sockets of the unit and those on the components.
• Use speakers of impedance ratings of 4 to 16 ohms. However if you wish to operate the unit in bridged mode
as a mono power amplifier with only one speaker, ensure the speaker is rated 8 ohms minimum. The speaker
impedance will be indicated on the back of the speakers or in the speaker's instruction manual.
• Use proper speaker cords - which your dealer will normally recommend - with as low capacitance content as
possible. The speaker connections (five-way binding posts) provided on the back of the amplifier are suitable
for banana plugs, as well as bare wire or spade lugs.
• If connecting the speaker cords directly with bare wire ends, we suggest you strip off about 1 cm of the
insulation shield cover from the ends of the speaker cords. Twist any exposed strands tightly, and insert the
ends fully and securely into the terminals on the rear panel.
• Check that the speaker cord ends (exposed tips) on the terminal posts, have no stray wires touching one
another, as this can cause short circuits and may damage both the amplifier and the speakers.
• When using the unit as a STEREO power amplifier make sure the BRIDGED switch is set correctly to the
STEREO position. Connect the Left and Right channels correctly between the speaker and the unit, and
ensure for each channel that the"+" and
terminals are also correctly matched.
• When using the unit as a MONO power amplifier (bridged mode): make sure the BRIDGED switch is set
correctly to the MONO position. Connect only one speaker to the power amplifier: connect the "+" speaker
lead wire to the LEFT "+" terminal post on the power amplifier and the
speaker lead wire to the RIGHT "+"
terminal post. Do not operate the amplifier with a common ground speaker switching device. This will damage
the amplifier (and void your warranty). Consult your dealer if in doubt.
2. CONNECTING THE PREAMPLIFIER
See Illustrations 2, 3 and 4 - when using the unit as a stereo power amplifier, a monaural amplifier or as a stereo
amplifier for bi-amplification, respectively.
• The stereo mode uses one preamplifier and one power amplifier.
• The "bridged" monaural mode uses one preamplifier and two mono power amplifiers
• The bi-amping mode uses one preamplifier or control amplifier, which has two sets of outputs connected in
parallel, and two stereo power amplifiers, one driving the tweeters and the other driving the woofers of the
speakers, which have separate connectors for the tweeters and the woofers.
• Ensure that regardless of the mode you choose, that the correct connections are done.
3. CONNECTING THE POWER CORD
• Always handle the power cord with care and never pull the plug out of the wall socket by tugging the cord.
Hold the plug to remove it from the wall.
• Ensure the VOLUME control is set to the minimum position before plugging in the power cord.
• Connect the power cord to the AC (mains) outlet.
• When plugging and unplugging make sure the power switch on the unit is turned off.
NOTES: Verify that all connections are properly and securely made and that the amplifier and components have
been plugged in. Using higher quality interconnect cables will improve sound quality
