The IRD-6185-RS is a professional quality, high performance, commercial satellite receiver with an integrated VideoCipher®** II RS descrambler module. This receiver is C and Ku band compatible, accepting signals in from 950 to 1450 ( a ) . Frequency selection is accomplished via front panel push button switches, supporting both C band transponder and direct frequency settings.

The receiver offers two modes of synthesized frequency control. A high-stability quartz crystal reference mode, with a 1 MHz tuning increment, allows for optimizing the receiver's TI immunity. An AFC mode is also included, which provides tracking of the LNB frequency drift of the input signal. An ultra-stable phase locked loop demodulator features superior threshold extension. This design delivers excellent picture quality, even under weak signal conditions. The IRD-6185-RS can be set to one of two aural subcarrier modes: fixed (6.8 MHz) and variable (5.4 to 8.2 MHz). An external 70 MHz IF loop allows TI filters to be insert-ed as needed. The IF loop comes with a standard 32 MHz IF bandwidth filter installed (optional filters are external).

     The IRD-6185-RS is housed in a single height, 1.75" high, rack mountable, steel chassis. The front panel design allows front of rack access to the descrambler module, battery replacement, authorization number, and renewable security (RS) card, without removing the IRD-6185-RS from its rack mounting. LNB power is multiplexed on the RF input connector, eliminating the need for external power inserters. User friendly controls (video polarity, on-screen display, fine tuning, audio and video level) and indicators (signal strength, sync, authorization, and bypass) simplify installation. Features required for General Instrument compliancy are also provided, including a ganged audio (stereo L/R and mono) level control, audio mode switch for calibrated factory or variable audio level, and an automatic resetting thermal breaker for the LNB power.
