User manual RANE MQ 15

[. . . ] FOR BEST NOISE PERFORMANCE ALWAYS POSITION BOTH CONTROLS AS FAR TOWARD THE TOP OF. See the Operating Instructions on the back page for more information, Most applications require only a few dB of boost or cut. Start with the RANGE switch in the 6dB position and increase to 12dB only if necessary. Setting curves is as easy as it is on all Rane graphics thanks to our unique interpolating constantQ circuitry. [. . . ] This yellow LED lights any time remote power is supplied from either a RS 1 single power supply or a RAP 10 multiple power supply. Note that this indicator is electrical, not political. SYSTEM CONNECTION (continued) EXPANDING. Expanding and/or daisychaining the inputs and outputs normally uses the 1/4" jacks. Three parallel input connectors allows driving a second signal processor or amplifier without special cabling. The PATCH I/O (Input/Output) jack makes connection to mixer Effects Loop insert points very simple. Just connect a shielded stereo tip-ring-sleeve (TRS) cable between the PATCH I/O jack and the TRS Effects Loop insert on your console. (Your mixer must use the tip=send, ring=return Effects Loop wiring convention. ) SIGNAL LEVELS. Signal levels from -10dBV to +4dBu are considered normal and within range (at least 16dB of headroom exists above these levels). Use a mic preamp (e. g. , Rane model MS 1) first. REAR PANEL DESCRIPTION 1. This 1/4" TRS connector parallels the 3-pin connector described above. The +, ­, and COMMON GND terminals of the barrier strip parallel the respective pins in the 3-pin and 1/4" connectors. This 1/4" TRS connector parallels the 3-pin connector described above. This 1/4" 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 MQ 15/MQ 30 into Effect Loops as painlessly as possible, using a single 1/4" 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. [. . . ] This sort of test equipment lets you analyze the response of the combination of room and sound system and is the only accurate means available for setting up the MQ 15/MQ 30 properly. If you are unable to utilize science in this way, your ears will have to be the judge. It is a very good idea to always start the equalization process with the filter RANGE switch in the ±6dB position. It should stay there unless you absolutely cannot achieve your goal any other way.
