User manual BIAMP PM602

[. . . ] It accepts standard unbalanced line-level input from a program source, as well as unbalanced line-level input (up to 25V) from a paging source, and provides a standard unbalanced line-level output. The PM602 uses FET gates for noiseless switching. It is designed for use with Advantage IWA and RPM Series powered mixers, but may be inserted into any system. [. . . ] It is designed for use with Advantage IWA and RPM Series powered mixers, but may be inserted into any system. The PM602 consists of a metal box (3. 35" H x 4. 1" W x 1. 7" D), with an internal circuit board and an external power transformer. Screw terminals on the circuit board provide connections for the page input, program input, and output signals, as well as an external contactclosure (switch) for manual activation of the page-override function. Screwdriver-adjustable trim controls are also provided on the circuit board for adjustment of the automatic page-override sensitivity, the program return time, and the page input gain. The PM602 may be inserted anywhere between the source (mixer) and the output (amplifier) of a sound system. When used with the Advantage IWA or RPM Series powered mixers, the PM602 is connected at the mixer Main (or Zone) patch point. The mixer Main/Zone Out terminal is connected to the PM602 program input and the PM602 output is connected to the mixer EQ In terminal. An external page source is then connected to the PM602 page input. Also use this approach when connecting the PM602 at the main patch point of other mixers, where send goes to PM602 Program Input (+) and return goes to PM602 Output (+), with a single common ground connection. Finally, connect an external page source to the PM602 Page Input (line-level up to 25V). For manual activation of page override, wire an external contact-closure across the Manual Trigger terminals of the PM602. This can be a push-to-talk switch, a relay, or even an `open collector' logic output. Whenever manual triggering is used, Page Override Threshold should be set fully clockwise (maximum). Once all connections have been made, replace the PM602 front cover (access holes are provided for adjusting controls). Turn the sound system on and set it for appropriate program and output levels. Then adjust Page Level for the desired `page-to-program' level. [. . . ] Turn the sound system on and set it for appropriate program and output levels. Then adjust Page Level for the desired `page-to-program' level. Page Level is factory set fully counter-clockwise (off). [. . . ]
