[. . . ] S-4000 S-4000S 40 CH I/O MODULAR RACK S-4000H FOH UNIT S-4000R REMOTE CONTROLLER Owner's Manual Before using this unit, carefully read the sections entitled: "IMPORTANT SAFETY INSTRUCTIONS" (S-4000S Owner's Manual Pg. 2), "USING THE UNIT SAFELY" (S-4000S Owner's Manual Pg. 3), and "IMPORTANT NOTES" (S-4000S Owner's Manual Pg. These sections provide important information concerning the proper operation of the unit. [. . . ] (More on the S-4000R in a little bit. ) · · S-4000H 32x8 FOH Unit The S-4000H is the front-of-house (FOH) connection interface for the S-4000 System. As such, its I/O configuration is the opposite of the S-4000S--8 audio inputs and 32 audio outputs. As it name suggests, the S-4000H FOH Unit's main application is near the FOH mixing console. However, the S-4000H can be used anywhere you need to receive stage audio from the S-4000S--at a monitor console, a multi-channel recording device, a broadcast feed, etc. Additionally, multiple S-4000H units can be used for split destinations when connected to the system via an Ethernet switching hub. See Chapter 7 for details. About the S-4000H's Audio I/O The S-4000H's audio I/O is provided on standard DB-25 connectors. Each connector supports eight channels of audio. · · One input connector--provides eight channels of balanced line level audio. Each input channel is equipped with a 24-bit/96 kHz A/D converter. Four output connectors--provide eight channels of balanced line level audio per connector. Each output channel is equipped with a 24-bit/96 kHz D/A converter. By providing audio on DB-25 connectors, breakout cables can be easily connected for a quick and clean setup. RSS offers the following optional breakout cables: · · SC-A0805DM--4. 5 meter male breakout cable to connect S-4000H outputs to audio destinations (DB-25 connector to eight male XLR connectors). SC-A0805DF--4. 5 meter female breakout cable to connect audio sources to S-4000H inputs (eight female XLR connectors to DB-25 connector). If desired, you can purchase third-party breakout cables or fabricate your own to suit your requirements. See Appendix B: Connector Information for information about the S-4000H's DB-25 connectors. S-4000 Digital Snake Owner's Manual 39 5--S-4000 System Overview Why Doesn't the S-4000H Have Remote Controlled Preamps? Since the S-4000H is designed to be used near the mixing location, its audio inputs will most often receive line level audio from the mixing console (e. g. , to feed amplifiers at the stage position). In this application, variable gain preamps are unnecessary, since the audio level can be easily adjusted at the source. As such, the S-4000H's inputs are fixed at line level (+4 dBu). The signal level at the S-4000H inputs can be monitored from the S-4000R or the S-4000 RCS. S-4000R Remote Controller The S-4000R functions as a remote controller for the S-4000 System. It can be connected to either the S-4000S or S-4000H unit, whichever is most convenient for you. · S-4000S input channel control--The S-4000R provides control over the S-4000S's input channels. This includes preamp gain adjustment, phantom power and pad on/off status, and channel linking. Input level monitoring--An eight-segment LED meter allows for precise preamp gain adjustment of the S-4000S's input channels. Additionally, the meter can be used to view signal levels from the S-4000H's audio inputs. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ­ Reorient or relocate the receiving antenna. ­ Increase the separation between the equipment and receiver. ­ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
