Power Vector Mixer is an 8-channel mixer/pre-amplifier, offering a wide variety of operational features and functions for superior audio performance. Eight module bays accept plug-in input modules, allowing up to four levels of priority between modules. Two module bays are capable of accepting signal processing plug-in output modules. Each module is controlled by an independent volume control with an associated signal/clip LED for signal status, and an 11-segment LED output level meter that monitors output signal level. In addition, the VMIX has a motorized master volume control (that can be controlled using a remote control panel, RVCP, sold separately), bass and treble control, peak hold switch, unbalanced output jack, and balanced output terminal. Optional security covers prevent tampering of settings. The VMIX can be used for various applications including foreground music, background music, and paging. For large applications, several VMIX units can be bridged together.
