Product Overview The Biamp Commercial PREZONE2 is a multi-functional stereo preamplifier that independently controls music source selection and volume in two stereo zones. It also mixes two microphone levels with one of four music sources. This makes it a strong fit as a commercial zone preamplifier, a background music mixer, and a multi-zone source selector. Its intuitive front and rear panel design makes it suitable for a wide range of professional audio applications. Product Description The PREZONE2 provides two mic/line balanced inputs with 48V phantom power and four stereo line inputs, routed to two stereo output zones. Each zone offers independent source selection, volume control, and a mono/stereo switch, with balanced Euroblock and unbalanced RCA connectors. Four priority levels manage audio routing, and a 24V priority output overrides local volume controls per zone for emergency and paging scenarios. The unit includes tone control, a chime, VOX mute, wall panel control support, and a built-in web server for external device control. RS-232 control is available at 115200/8-N-1. Front-panel indicators show signal present, clipping, emergency mode active, paging active, and VOX active. The PREZONE2 has an internal universal power supply, auto standby mode, and a 2RU rack-mountable chassis. It is CE marked, UL listed, and RoHS compliant.
