SPEAKER TERMINALS
Follow the
(A/B/C/D+) (A/B/C/D-)
, channel and polarity markings,
making sure they match the channel and polarity of the connections at
the speakers.
MULTIPLE SPEAKER CONNECTION
PARALLEL- Each additional speaker decreases the load impedance
for the amplifier. The amplifier delivers more current and works
harder.

1.4 Installation- Self-Bridging, 2+1 Mode
BRIDGED MONO-
Connect a 4
Ω
ohm speaker to the
terminals marked
“(+), BRIDGE, (-)”
,
making sure they match the polarity
of the connections at the speakers.
Caution!
⇒
Speaker or multiple speaker loads
totaling less than 4 ohms are not
recommended for
“Bridged”
or
“2+1 Mode”,
and may damage the amplifier.
TA4600, TA4320
TA4600, TA4320--
Set the
“MODE”
switch to
“2CH, 3CH”,
or
“4CH”
and connect the
speakers accordingly. For
“3CH”
operation, bridge the
“C”
and
“D”
channels.
2+1 MODE- (TRI-MODE)
Simultaneous stereo and mono operation,
“2+1 Mode”
, requires a passive
crossover to send low frequencies to the mono speaker and higher
frequencies to the stereo speakers. The following table lists the
component values for a 6 dB/Octave crossover at common frequencies
using 4 ohm speakers for stereo and an 8
Ω
speaker for mono(subwoofer):
