Bi-Amplified System

In a bi-amplified system, array shading is accomplished by connecting separate amplifier channels to the HF section of each VRX932LA. In larger arrays, a single amplifier channel may be used for two adjacent loudspeak- ers. Array shading is then accomplished by adjusting the gain of the HF amplifier channels. For extremely pre- cise control over system performance, it may also be desirable to dedicate an individual system controller output to each HF amplifier channel.
