~ FOH Engineer Relies on GRAMMA Isolation Risers Decouple Guitar and Bass Amps on Stage ~
INDIANAPOLIS, IN â€” When Robert Randolph & The Family Band take to the stage to deliver an electrifying performance, front of house engineer Sean Quackenbush relies on Auralex GRAMMA (Gig and Recording, Amp and Monitor, Modulation Attenuator) isolation risers to decouple the groupâ€™s guitar and bass amplifiers from the stage. GRAMMA lets Quackenbush deliver a clean front of house mix without the additional boom and swell associated with non-isolated instrument amplifiers.
â€œRobert Randolph is on Rolling Stoneâ€™s list of the greatest guitarists of all time,â€? says Quackenbush. â€œIt is imperative that the mix for the front of house and the monitor system accurately reflect every nuance of each performance. One of the biggest headaches an engineer faces is from the acoustic coupling of instrument
amplifiers with the stage that creates wild swings in bass response. The Auralex GRAMMA isolation risers completely eliminate this type of problem, allowing me to concentrate on delivering the bandâ€™s great performance and not on solving acoustic problems with the EQ.â€?
The GRAMMA, patented by Auralex, is an effective isolation device that is used to float an amp or loudspeaker, yielding nearly total acoustic isolation between an instrument amp or monitor speaker and the stage. The effective result of employing a GRAMMA is clarity of sound that honestly represents the artistic intent of the performers. The standard GRAMMA is 23″ long x 15″ wide x 2.75″ high, with a maximum weight limit of 300 lbs. The Great GRAMMA offers a 30 percent larger surface area to accommodate popular speaker configurations that feature 4â€? x 12″, 15″ or 18″ speakers. The Great GRAMMA is 30″ long x 19″ wide x 2.75″ high and has a maximum load weight of 300 lbs.
â€œRobertâ€™s concerts are very inclusive of the audience and all the band members get to strut their stuff, so to speak, on different instruments,â€? explains Quackenbush. â€œThe GRAMMA isolation risers allow the band to hear what they are playing uncolored by stage coupling, so the performers are always very comfortable no matter which instrument or amp they are using. The GRAMMA is a real lifesaver.â€?
