Product Overview
The SF-PA100A is an audio power amplifier that receives three audio channels on an RJ45 Format-A connector. A selector feeds Pair A, Pair B or Pair C audio to the amplifier that provides a 70 V or 100 V constant voltage amplified output. At the normal gain setting, the output provides 100 watts for an audio level of +22 dBu. The three Format-A pairs feed through to the LOOP OUT jack to feed additional amplifiers or other Format-A receivers. Input gain is set by the installer using a rear-panel single-turn potentiometer with an associated dual-LED VU meter calibrated to 10 dB below maximum power output. The SF-PA100A is equipped with an internal VCA for setting the amplifier output level. The REMOTE CONTROL RJ45 jack provides for the connection of an RDL D-RLC10KM type remote level control. It is also possible to use the RJ45 jack to connect an external 10 kΩ potentiometer or a 0 to 10 Vdc control voltage. VCA control insures long term noise-free level adjustment. A selectable audio compressor is provided to add up to 15 dB additional headroom to the power amplifier input. The compressor is designed to remain aurally transparent using automatically adjusting attack and release times. The amplifier is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for all levels of expected voice or music modulation. The SF-PA100A is equipped to operate from an included external 48 Vdc power supply. The SF-PA100A is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX product is engineered and manufactured in the U.S.A. for continuous duty in demanding installations. The versatility of SYSFLEX products adds enormous flexibility in the design and installation of professional A/V systems.
