User manual RANE FSC 22

[. . . ] 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. This is an AC input and requires special attention if you do not have an operational power supply EXACTLY like the one originally supplied with your unit. A Rane Model FRS 8 or RAP 10 power supply is acceptable as well. SYSTEM CONNECTION Locating the FSC 22 in your system depends on the application. When assembling a sound reinforcement system, place the FSC 22 between the equalizer (if used) and the active crossover, or the power amplifier if using passive crossovers. [. . . ] Useful for A-B comparisons and to restore signal path should power fail. 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. 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. 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 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. 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. Using any other type of supply may damage the unit and void the warranty. See CHASSIS GROUNDING note on last page for details. OPERATING INSTRUCTIONS After properly wiring the FSC 22 into your system, normal operation begins. [. . . ] 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.
