9.6. Speaker Connections
Be sure to reattach the terminal cover after connections are completed.
Failure to do so could result in electrical shocks, as a high voltage is
applied to the speaker terminals. Also, take care to NEVER touch the
speaker terminals.
WARNING
Notes
• Connect only high-impedance 100 V line speakers to the unit. Connection of low-impedance speakers could
cause amplier failure.
• Carry out connections so that the total impedance at each speaker terminal is greater than the value shown
in the gure below (42 Ω). If the impedance is smaller than the indicated value, the amplier could fail.
Tips
• The unit is designed for a total impedance to be greater than the indicated value (42 Ω) when high-impedance
100 V line speakers are connected to each speaker terminal and the total wattage is less than 240 W.
• The unit can produce optimum sound quality conditions when the following TOA speakers are connected and
the speaker equalizer function is used. (see p. 21.)
For ROOM zone: BS-1030B, BS-1030W
For OUTSIDE zone: TC-631M, TC-651M

9.7. Extension Power Amplifier Connections
The unit is designed for connection to high-impedance 100 V line speakers, adding up to a total wattage of
240 W each for OUTSIDE and ROOM use. However, if more speakers are required, the power amplier can
be extended.

The sound volume of speakers connected
to the extension power amplier is not
interlocked with the front panel-mounted
outside and room volume controls.
Adjust the volume using the extension
power amplier's volume control.
Tips
• Output from the preamplier output jacks is
not interlocked with the front panel-mounted
outside and room volume controls.
• Output from the preamplier output jacks is
interlocked with the outside and room zone
output switches.
• Since the speaker equalizer affects output
from the preamplier output jacks, connect the
designated speakers (see p. 21.) to the power
amplier when the speaker equalizer switch is
ON for the zone(s).
• For more information on connecting speakers to
the extension amplier and use of the extension
amplier, see the instruction manual enclosed
with the amplier.
