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
loudspeakers. Array shading is then accomplished by adjusting the gain of the HF amplifier channels. For
extremely precise control over system performance, it may also be desirable to dedicate an individual system
controller output to each HF amplifier channel.
