User manual RANE FME 15

[. . . ] Setting curves is as easy as it is on all Rane graphics thanks to our unique interpolating constant-Q circuitry. For more information on setting up your curves correctly, again, see the back page. NEVER CONNECT ANYTHING EXCEPT AN APPROVED RANE POWER SUPPLY TO THE RED THING THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF THE FME 15. This is an AC input and requires special attention if you do not have an operational power supply EXACTLY like the one that was originally packed with your unit. [. . . ] These fifteen slide controls set the individual levels of the interpolating constant-Q filters. Their range is selectable between ±6dB (use bottom or right-hand scale) and ±12dB (use top or left-hand scale). The grounded center-detent design of these sliders ensures all filters are off when positioned to their centers. Sets the overall range of all sliders between ±6dB and ±12dB. This yellow LED lights any time remote power is supplied from either a RS 1 or VC 18 single power supply or FRS 8 or RAP 10 multiple power supply (but not in the presence of Popes, Queens and Presidents as one might well expect). REAR PANEL DESCRIPTION 1. This ¼" TRS connector parallels the 3-pin connector described in item #1. The "+", "­", and COMMON GND terminals of the #6 terminal strip parallel the respective pins in the 3-pin and ¼" connectors. This ¼" TRS connector parallels the 3-pin connector exposed in item #5 below. Active balanced Outputs operated in the unbalanced mode use only pin 2 driving the line and pin 1 acting as the return. Grounding pin 3 will not cause any damage nor will it impair the sound. It only creates extra work for your audio electrons and is unnecessary. You may use more than one type of OUTPUT connector simultaneously to drive multiple devices. This ¼" TRS jack provides an unbalanced I (Input) on its tip and an unbalanced O (Output) on its ring. Designed for use with tip=send/ ring=return effect loop inserts found on many mixing consoles. This provides an easy means for patching the FME 15 into effect loops as painlessly as possible, using a single ¼" TRS stereo patch cable. CAUTION: USE EITHER THE PATCH I/O OR ANY OF THE INPUT AND OUTPUT CONNECTORS--DO NOT USE BOTH AT THE SAME TIME. This switch provides the ability to separate chassis ground and signal ground. In some circumstances, moving it to the opposite position eliminates stubborn hum and buzz problems. [. . . ] Since acoustic compensation and tone contouring are two of the most common uses for equalization, here are a few words on each: ACOUSTIC COMPENSATION. Acoustic compensation is controlled nicely with a device such as the FME 15. The best way to find out what room acoustics are doing to your sound is to use either a real time analyzer or computerized measurement systems such as time delay spectrometry or other similar devices. This sort of test equipment lets you see the response of the combination of room and sound system and is the only accurate means available for setting up the FME 15 properly. [. . . ]
