Introduction
About this document
This manual is intended to give relevant information on the system
features, available equipment, typical configurations, simplified wiring
and programming and technical data for the concept.
This document is aimed at:
- Consultans
- Installers
- End users
Equipment covered by this document
Public adress amplifiers:
- VPA-120 (120 W)
- VPA-240 (240 W)
