User manual RANE MQ 30

[. . . ] Anyone familiar with other graphic equalizers finds the MQ 15/MQ 30 just as familiar. One word of caution: the boost/cut RANGE switch drastically changes the impact of a given filter. Setting the IN and OUT GAIN controls to the same physical positions gives unity gain through the equalizer. That is, moving both slider handles together (keeping them aligned) always maintains overall unity gain from input to output. [. . . ] 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 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. The MQ 15/MQ 30 is designed for all line-level signals. Signal levels from -10dBV to +4dBu are considered normal and within range (at least 16dB of headroom exists above these levels). Do not directly connect microphones into the MQ 15/MQ 30. Use a mic preamp (e. g. , Rane model MS 1) first. REAR PANEL DESCRIPTION 1. Pin 2 is positive, pin 3 is negative and pin 1 is signal ground. For unbalanced operation, use pin 2 as hot and pin 1 as return. This 1/4" TRS connector parallels the 3-pin connector described above. Tip is positive, ring is negative and sleeve is signal ground. The +, ­, and COMMON GND terminals of the barrier strip parallel the respective pins in the 3-pin and 1/4" connectors. Used for primary inputs and outputs or additional patch connections. This 1/4" TRS connector parallels the 3-pin connector described above. As before, tip is hot, ring is not and sleeve is signal ground. Pin 2 is positive, pin 3 is negative and pin 1 is signal ground. This 1/4" TRS jack provides an unbalanced I (input) on its tip and an unbalanced O (output) on its ring. [. . . ] It should stay there unless you absolutely cannot achieve your goal any other way. Then and only then should you go for the ±12dB position. Use the BYPASS switch to compare equalized with unequalized sound. Compare the two and set the equalizer as best you can using controlled noise sources, sweep signals, or source material that you are VERY familiar with. [. . . ]
