4 Zones Installation Mixer

The ZPR-4620 4-Zone mixer is the most versatile choice for medium-sized multi-zone sound systems build around a stereo main zone. The unique CascadeZone© concept allows the three additional mono zones to either carry the same signal as the stereo zone or any of the 6 individual input signals. All essential controls are located on the front panel, while some specific settings can only be made on the rear panel. This includes zone adjustments like maximum level settings, equalization and 100Hz Highpass filters. The combination of front-panel and rear-panel controls make this unit ultimately flexible while still being user-friendly even for less experienced operators.
