B4R Bass Amplifier
Connections:
In the example shown below, the B4R’s two internal power amplifiers are bridged together to produce maximum output power. Set the Stereo/Mono Bridge switch to the IN (Mono Bridged) position and connect the system as follows:

NOTE: BE ABSOLUTLEY CERTAIN THAT THE CABINET(S) ARE ABLE TO HANDLE THE EXTREMELY HIGH OUTPUT POWER OF THE AMP IN THIS MODE!
1: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 a speaker cabinet capable of handling the extremely high output power. (Speakon® : pin 1 +, 2 +; Banana: Mono +, Mono
In the example shown below, the B4R’s two internal power amplifiers will each power a set of full range cabinets.
Set the Stereo/Mono Bridge switch to the OUT (Stereo) position and connect the system as follows:

1:Connect a speaker cable from the B4R’s Power Amp A Speaker Output jack to the input jack(s) of a set of full range speakers.
2:Connect a speaker cable from the B4R’s Power Amp B Speaker Output jack to the input jack(s) of another set of full range speakers.
In the example shown below, the B4R’s two internal power amplifiers will power both a full range cabinet and a low frequency cabinet. The crossover point is determined by the Biamp Frequency control (#16).
