INTRODUCTION Thank you for your purchase of the ISP Technologies High Definition Distributed System HDDS SM800 Surface Mount Speaker. This product provides a new level of performance in distributed audio systems allowing greater system flexibility and easy installation of distributed sound. All connections are made via CAT6 RJ45 connections making installation of systems faster and easier using the HDDS SM800.
OPERATION The HDDS Master Control Module is the Master control center for distributed sound systems using the HDDS technology. The Master Control Module includes six zones that can be used independently or can be linked to work together allowing the system designer the flexibility to set up any system with the desired configuration. The block diagram below shows the basic configuration of the HDDS SM800 Surface Mount Speaker.
Rear Panel The rear panel of the HDDS SM800 includes two RJ45 connectors, connect the INPUT to the output of the HDDS Master Control Module and the output can be used to connect to not more than one additional SM800 speaker. The maximum CAT6 cable length should not exceed 300 feed. The level control allows individual speakers to be balanced in a given system. The HDDS SM800 will typically pull less than 2 amps of current from the output of the Master Control Module at average listening levels.
CAT6 Connections The figure below shows the connections for each output A, B and C of each zone output on the Master Control Module and also connections between each HDDS SM800 speaker. Connections are done via standard CAT6 cables where pins 1 through 8 are connected common to the same pins 1 through 8 at each end. As shown below two wires in the Cable are used for balanced audio and 6 wires are used for power with two providing ground and two for each of two 22VAC power signals fed down the cable.
