INTRODUCTION

The UZ-25II is designed for remote volume control of multiple amplifiers or powered speakers in a distributed audio
system. Two stereo sources are available to each of five output zones. Each source input pair handles separate left and
right balanced line level signals. Each output zone features independent level control from inputs 1 and 2, stereo/mono
selector with mono indicator, LED level metering, and left and right balanced line level zone outputs. All audio connections
are balanced XLR. The built in power supply and single high 19" rack mount format allows for easy installation and reliable
Operation.
What Is A Zone Distribution Mixer?
The use of multiple power amplifiers, each driving one or more speakers, or multiple powered speakers is now
commonplace in most distributed audio systems. Whether the installation is a club, a hall, a restaurant, a church, an arena,
an office, a recreational facility, or even a portable PA with distributed speakers, systems like this offer the potential to
balance the audio level throughout the coverage area. You can adjust the volume of every amplifier or powered speaker,
either in groups or individually, from a centralized location with a zone distribution mixer like the Model UZ-25II. Basically
the input of the Model UZ-25II is connected to the PA mixer's line-level output (the Model UZ-25II will accept the output of
two mixers or stereo signal sources) and the power amps or powered speakers are connected to the Model UZ-25IIs zone
outputs. As you adjust volume for each zone within the system the independent LED level metering gives a quick visual
reference to the level variations throughout the system.
