B4R Bass Amplifier
In the example shown below, the B4R’s two internal power amplifiers will power both a high frequency cabinet and a low frequency cabinet. The crossover point is determined by the Frequency control (#16).
Set the Stereo/Mono Bridge switch to the OUT (Stereo) position and connect the system as follows:

1: Set the Full Range/Biamp switch to the IN (Biamp) position.
2:Connect a speaker cable from the B4R’s Power Amp A Speaker Output jack to the input jack of the low frequency cabinet(s).
3:Connect a speaker cable from the B4R’s Power Amp B Speaker Output jack to the input jack of the high frequency cabinet(s).
In the example shown below, the B4R’s two internal power amplifiers are bridged together and will power the low frequency cabinet(s). Asecond amplifier will be used to power the high frequency cabinet(s). The crossover point is determined by the Frequency control (#16).
Set the Stereo/Mono Bridge switch to the IN (Mono Bridge) position and connect the system as follows:

1:Connect a shielded cable from the B4R’s Biamp High Output jack to the Input jack of the High Frequency power amplifier.
2:Connect a shielded cable from the B4R’s Biamp Low Output jack to its Power Amp A Input jack.
3:Connect the high frequency power amp’s Speaker Output jack to the input jack(s) of the high frequency cabinet(s). (Observe amplifier’s minimum load rating!)
4:Connect a heavy duty speaker cable terminated with a Speakon® connector or dual banana plugs from the B4R’s Mono Bridge / Biamp Output jack to the input jack of the low frequency speaker cabinet. (Speakon® : pin 1 +, 2
