SP1200 Quick Start
This isn’t a substitute for reading the entire instruction manual, which is the only way to fully understand how the SP1200 works. However, the Quick Start provides a quick overview so you can get the SP1200 set up and working right away.
Make sure the power switch is off while setting up and making connections to the SP1200.
External Switch Settings
•The Paging Mic and the Local Mic have +24 VDC PHANTOM power switches. Move the switches down to activate the phantom power if you are using condenser microphones.
•The Paging Mic and Local Mic also have GAIN +40 dB switches. Leave the switches in the down position when microphones are connected to these inputs.
•If you plan on connecting two or more SP1200s together in a system with the EXPANSION IN/OUT bus, use the LOCAL/REMOTE switches. They select either the local Program Input source (switches up) or a remote program source from the EXPANSION IN/OUT bus (switches down). The
•To operate two SP1200s with one remote control, assign the same AMP ADDRESS setting to both amplifiers (DIP switches
•For independent zone operation, assign different AMP ADDRESS settings to each amplifier. The front panel and remote control panels will operate independently for each amplifier and zone.
Internal Switch and Jumper Settings
Refer to “Internal Settings” on page 13 for more information.
•Bus Assign switches are used to assign a program input source to the balanced expansion bus. There are four switches for each program input source: Left (+), Left
CAUTION: When using multiple SP1200s that use the expansion bus, these switch
settings must be unique to each unit or you can damage your SP1200(s). Never assign more than one program source to the same channel on the Expansion Bus.
