Total Harmonic Distortion

Master modules (-M) have the circuitry and connectors for fiber-optic transmission.  Slave modules (-SL) must be linked to a master module with the optional linking cable; LKI-6 for input modules, LKO-6 for output modules.  This allows one master and up to five slave modules to connect to the fiber-optic cable, for up to 12 channels of full bandwidth audio.  The input master is the FBAI-M (analog input) module.  Output masters are the FBAO-M (analog) or the FBDO-M (AES/EBU digital).  Input slave modules are the FBAI-SL and the DATI-SL (data).  Output slaves are the FBAO-SL and the DATO-SL (data).  Any master module can also be used as a slave module, giving you the most flexibility possible.

Units are not shipped with a 12-volt plug-in wall-type transformer power supply.  They may be installed as a stand-alone box or up to 3 units may be mounted in a 19-inch rack panel using the optional RMK rack mount kit.

The master modules are for multimode fiber cable standard or for singlemode (option -SM) fiber.  The standard fiber connector is the ST connector, assuring ease of use and fast set-up in the field or on the sound stage.  FC connectors are also available.
