In this example, the SVT-4 PRO’s two internal power amplifiers will power both a high
frequency cabinet and a low frequency cabinet. The crossover point for the cabinets is
determined by the Crossover Frequency control [21]. Disengage the Stereo/Mono Bridge
switch [Stereo position]. Connect a shielded cable from the SVT-4 PRO’s Bi-amp High Output
jack to its Power Amp B Power Amp In jack. Connect a shielded cable from the SVT-4 PRO’s
Bi-amp Low Output jack to its Power Amp A Power Amp In jack. Next, connect a speaker
cable from the SVT-4 PRO’s Power Amp A Speaker Output jack to the input jack of the low
frequency cabinet(s). Finally, connect a speaker cable from the SVT-4 PRO’s Power Amp B
Speaker Output jack to the input jack of the high frequency cabinet(s).
In this example, the SVT-4 PRO’s two internal power amplifiers are bridged together and
will power the low frequency cabinet(s). A second amplifier will be used to power the high
frequency cabinet(s). The crossover point for the cabinets is determined by the Crossover
Frequency control [21]. Engage the Stereo/Mono Bridge switch [Mono Bridge position].
Connect a shielded cable from the SVT-4 PRO’s Bi-amp High Output jack to the input jack of
the High Frequency power amplifier. Connect a shielded cable from the SVT-4 PRO’s Bi-amp
Low Output jack to its Power Amp A Mono Bridge Input jack. Next, connect the high
frequency power amp’s Speaker Output jack to the input jack(s) of the high frequency
cabinet(s). [Observe the amplifier’s minimum load rating]. Finally, connect a heavy duty
speaker cable terminated with a Speakon connector [pin 1+ = “+”, pin 1– = “–”] from the
SVT-4 PRO’s Mono Bridge Output jack to the input jack of the low frequency speaker cabinet.
