User manual RANE FSC 22

[. . . ] Set the LEVEL controls to "7" for unity gain--a good place to start. When used with true stereo program, press the SYSTEM MODE switch in to the SLAVE position. This causes both Channels to operate equally if either exceeds its THRESHOLD setting. NEVER CONNECT ANYTHING EXCEPT AN RS 1 OR OTHER APPROVED RANE AC POWER SUPPLY TO THE RED CONNECTOR THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF THE UNIT. [. . . ] In the in (SLAVE) position, this switch causes both Channels' Compressors to act together, i. e. , they are "slaved". All controls for both Channels remain active, so independent settings are still possible; however, whenever a signal in either Channel exceeds its setting, then both Channels change by the same amount. In the out (DUAL) position, both Channels operate independently. This concentric control increases or decreases the output Level for each Channel. Unity gain is about "7" for balanced outputs, and "8" for unbalanced outputs. Illuminates any time either output signal gets to within about 4dB of clipping. Occasional flickering is okay, continuous is not. Hey, if it's lit, you're fit; if not, call a doc. And while we're on the subject of power, let me take this opportunity to tell you just what I think about runaway government . . . REAR PANEL DESCRIPTION 1. An active balanced input ultilizing a combo connector compatible with either a 3-pin (XLR-type) or a ¼" TRS plug. Polarity follows the AES/ANSI/IEC standard of pin 2 (tip) positive, pin 3 (ring) negative and pin 1 (sleeve) signal ground. In its +4dBu position, the input gain is unity. In the ­ 10dBV position, the input gain is increased by 12dB (although mathematically suspicious, it really is 12dB, not 14dB). This compensates for so-called "semi-pro" (which I guess means you sorta get paid) recording equipment. THE FRONT PANEL CALIBRATION MARKS ASSUME THIS SWITCH IS IN THE +4dBu POSITION. The only exception to this is the Output Meter Mode marks which remain accurate in either position. These connectors follow the polarity convention outlined above. Wired in parallel, both connectors may be used simultaneously, if needed. In its LIFT position, signal ground and chassis ground are not connected. This unit is supplied from the factory with a Model RS 1 Remote Power Supply suitable for connection to this input jack. This unit's power requirements call for an 18 volt AC center-tapped transformer only. NEVER USE A POWER SUPPLY OTHER THAN THE ONE SUPPLIED OR AN EXACT REPLACEMENT OBTAINED FROM RANE CORPORATION. [. . . ] The unit is shipped with this switch in the "grounded" position, tying circuit ground to chassis ground. If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units somewhere. Your mission, should you accept it, is to discover how your particular system wants to be grounded. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
