[. . . ] These adjustments set the AFT660 to activate its 2:1 compression when the sound pressure level in the auditorium reaches 85 dB. As stated before, the end user may wish to set the threshold level to a higher or lower Installation Inputs and Outputs The output of the digital decorder should feed directly into the input of the AFT660 for the unit to operate properly. However, if desired, the AFT660 can be installed after the processor so that the AFT660 can monitor the levels of both optical and digital prints using the Afterburner Breakout board (Part #0660A390). See the Afterburner Breakout board section of the Setting the Threshold Levels instructions. See section 5 for configuration diagrams for various types of systems. If the AFT660 is installed into an existing digital sound system, it will not effect any calibration settings that were made previously. Only the threshold levels of the AFT660 need to be adjusted. The AFT660 has two inputs, both of which are connected together in parallel. One input is a female DB25 connector, and the other is a header pin connector. Both will accept the outputs of any six channel digital decoder. Only one input will be used and the choice will depend on the other equipment used (see hookup diagrams). Smart offers adapter cables to mate any digital decoder to the AFT660. See the illustrations at the end of the manual for specific hookup instructions. The AFT660 has two outputs, both of which are connected together in parallel. One output is a male DB25 connector, and the other is a header pin connector. The output from the AFT660 will mate with the rest of the sound system. On SMART processors, this will be the digital inputs on the processor. See the illustrations at the end of the manual for specific hookup instructions. Setting The Threshold Levels There are two threshold levels on the AFT660 that need to be set after hooking the unit into the sound system. One is the threshold level for the five main channels (Left, Center, Right, Left Surround & Right Surround). The other is the threshold level for the Subwoofer chan- 3 AFT660 Afterburner & AFT660PnP Digital Plug 'N Play setting depending on their requirements. Other Digital Decoders: If there is a pink noise source available for the system, play it through the Left channel. [. . . ] Connect from the ANALOG OUT and AUTOMATION ports on the back of the DTS-6D (or the SIGNAL and CONTROL ports on the Rover Panel) to the SIGNAL and CONTROL ports on the front of the Plug 'N Play, respectively. Connect from the back of the digital player (or the front of the Rover Panel) to the SIGNAL and CONTROL ports on the front of the Plug 'N Play. Connect from the back of the SDDS to the SDDS SIGNAL and CONTROL ports on the front of the Plug 'N Play. The EXTRA CONTROLS connector is a DB25 plug which carries the extra signals described in the Specific Digital Player Features section. [. . . ]
