The Technical Stuff

__________________________________________________________

Other double-mic applications often requiring phase inversion include piano soundboards, drum heads

(one mic on top of the drum and the other below it), and acoustic guitar miking, where one mic is

placed close to the soundhole and another further away or behind the guitar.

Low Cut Filtering

A common method for optimizing mixes is to apply low-cut filtering whenever possible. Excessive low

frequencies from microphones and instruments tend to build up in the mix, creating sonic “mud” that

masks musical detail, overloads or fatigues the listener’s ears, and sucks energy from power amps

and speakers. It isn’t uncommon to notice meters showing noticeably lower levels after low-cut

filtering is applied—a sure sign that such filtering was necessary. In addition, after low-frequency

mud is filtered, there is often more room in the mix to bring up important musical elements such as

vocals and lead instruments, resulting in a win-win situation (less mud = more music).

Typically, a low cut filter can be used to remove: vocal "B","P" and other popping sounds; moving-air

noise from close-miked vocals, drums, guitars and outdoor weather; instrument body noise from

handling guitars, basses, pianos, saxophones, etc; mic-stand vibrations; studio or stage floor

vibrations; air-conditioning; electrical hum; and unwanted proximity-effect bass boost.

Rack Mounting

The 710 ships with all the necessary brackets and hardware required for mounting one or two units in

a standard 19" rack; the only tool necessary is a medium Phillips-head screwdriver. When mounted,

the 710 takes two rack spaces. Bracket and hardware locations are shown below:
