It must be noted that the phase of the output signal from the slave amplifier operated through the AMP INPUT
is inverted by 180° in relation to the master amplifier. Thats why the slave amplifiers subwoofer must be
connected with inverted polarity in normal master/slave mode (see also Fig. 4, "SPEAKER" connectors for
Amplifier B), i.e. loudspeaker plus pole to minus terminal and loudspeaker minus pole to plus terminal on the
amplifier.
This is independent of the setting of the phase selection switch, which is exclusively for optimizing phase
response between subwoofer and satellites.
5.7 MASTER/SLAVE MODE WITH TWO BRIDGED AMPLIFIERS
Two Pantera Digital 1000 may be bridged together to increase performance, the loudspeakers’ minus terminals
must be interconnected with the loudspeaker cables and the loudspeakers connected as shown in Fig. 5.
FIG. 1 POWER SUPPLY / REMOTE SWITCH-ON CONNECTION
(1) GND terminal for the ground, to the battery’s minus pole
(2) REM terminal for remote switch-on
(3) Terminal for +12 V battery voltage
(4) Battery
(5) Cable fuse
(6) To your car radio’s automatic aerial connection
If your car is not equipped with an automatic aerial connection, connect this cable’s plus pole (+) to the
ignition lock. An on/off switch should be inserted in this case. Make sure that this switch is switched off if
the amplifier is not used.
FIG. 2 OPERATION WITH STEREO CAR RADIO
Connect and set the amplifier as shown in Fig. 2 if it is to be controlled by a car radio with two output channels.
(1) To the car radio, left output
(2) To the car radio, right output
(3) Subwoofer
FIG. 3 OPERATION WITH ONE CAR RADIO WITH SUBWOOFER OUTPUT
(1) To the car radio, subwoofer output
(2) Subwoofer
FIG. 4 USE IN MASTER/SLAVE MODE, UNBRIDGED
(1) To the car radio, subwoofer output
Note: instead of a car radio with subwoofer output, a normal STEREO radio may be connected to the
"PREAMP INPUT" jacks (L and R).
(2) Subwoofer
