CONNECTION OF MASTER AND SLAVE MODE SPXL 1000
14 Phase control
This control enables the phase of the bass signal to be shifted by
180° in order to achieve optimum delay equalization with the
other channels.
15 Remote bass control connector
To control the bass level from the driver position.
16 Master and Slave Mode
The SPXL 1000 is a „real-mono“ amplifier. In order to double the
power it can be connected to a second SPXL 1000 via the Master
and Slave Mode. In order to operate two amplifiers in this mode,
they must be connected with a RCA cable (In/Out). Amplifier1
(Master) takes over the complete control (active crossover, gain
etc.) and provides the +signal at the bridge out speaker connec-
tor (see No. 6 and figure page 7). Amplifier 2 (Slave) provides the
-signal at its bridge out speaker connector for the subwoofer (see
No. 6 and figure page 7).
Attention: Make sure that amplifier1 is switched on
master and amplifier 2 is switched on slave. In this mode
the minimum impedance is 2 ohms.
17 Power LED
Shows the operation mode of the amplifier.
18 Protection LED
The red LED indicates malfunctions of the amplifier.
The SPXL amplifier has several electronic protection circuits that
shut off the amplifier at overheating, overloading, short-circuit on
loudspeaker, low-ohmic mode or defective power supply.
Please check for connecting failures such as short-circuits, wrong
connections and over-temperature.
If the amplifier does not turn on it is defect and has to be send to
your local authorized dealer for repair service. A detailed descrip-
tion of the malfunction and the purchase receipt has to be atta-
ched.
