Bi-amplification (VR2 and VR3 only)
Bi-amplification requires using separate amplifiers dedicated to high and low frequencies. Using more than one
amplifier can enhance the dynamic performance of your system. “Splitting the load” between two amplifiers lets
each amplifier work less hard, increasing the available current to the drive units. When making all connections, be
sure to connect + to + (red) and – to – (black).
1. Unscrew the terminal collars of both sets of terminals and remove the jumper straps.
2. Connect the wires from the bottom set of terminals to the amplifier driving the woofers.
3. Connect the wires from the top set of terminals to the amplifier driving the midrange/tweeter.
CAUTION: Do not use an external active crossover with your VR speakers. The external crossover and the VR’s
internal crossover can interact and distort the phase and frequency response of the system.
