AMPLIFIER MODES
ТА604
L
and
TA604DL
amplifiers operate only in four-channel mode, i.e. each
channel is connected to its load. In
TA604
and
TA604D
amplifier each channel can be
used individually, as well BRIDGE mode can be used for each channels pair. Input signal
and load connection for
TA
series amplifier is shown in the picture below.
TA604
Four-channel Mode
TA604
Two-channel (BRIDGE) Mode
The loudspeakers are connected to the respective channels. The polarity of
connection is shown on the rear panel near corresponding sockets. Nominal impedance
should be not less than 4 Ohm. Balanced input signal of each channel is applied to the
corresponding input.
Gain control is performed via controls of the corresponding channels.
Loudspeakers are connected between channel 1

output
for channels 3-4 pair. Nominal impedance should be not less than 8 Ohm. Balanced input
signal is applied to channels 1 and 2 (3 and 4) simultaneously at bridge connection of
these channels. Gain control is performed via controls of both channels, connected in
bridge mode. The controls should be installed in the same position.
