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:
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).
Set the Stereo/Mono Bridge switch to the OUT (Stereo) position and connect the system as follows:
1: Connect a shielded cable from the B4R’s Biamp Low Out jack to its Power Amp A Power Amp In jack.
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 full range cabinet(s).
