The Auralex Audio Engineers Pack contains nine ISO Series products specially designed for acoustical engineers and audiophiles to boost the quality of sound in any recording or listening space. It includes a GRAMMA AE, 1 set of MoPADs, a pair of 6" Trap¢Xpanders, a pair of 8" Tri¢Xpanders, and 3 Platfeet.

Gramma AE
The GRAMMA AE (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker. GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed.

The specially designed Auralex MoPad Monitor Isolation Pads will instantly decouple your monitors from the room and greatly increase monitoring accuracy. No matter how good the rest of your studio gear, you won't get accurate monitoring if the direct transfer of vibrations from your monitors to your furniture is coloring your sound. Includes 4 pads 12" long by 4" wide.

Trap¢Xpanders and Tri&bullXpanders
In the art of audio sound capture, the recording engineer must contend with and balance many sonic issues (external noise bleed, structure-borne resonance, off-axis colorations) in order to arrive at sounds that are truly sonically robust.

Auralex's Trap¢Xpanders and Tri¢Xpanders give the recording engineer a high-degree of control by providing the capability to filter the undesirable external overtones that tend to push the engineer to over-process on the back-end during the mixing stage.

They offer the recording engineer a means of tonal control and passive filtering before the sound ever hits the signal path and before ever reaching for a knob or booting-up a plug-in. Trap¢Xpanders are trapezoidal in shape while the Tri¢Xpanders are triangle shaped.

Use the Trap¢Xpanders behind the drum mic to virtually eliminate off-axis colorations between your snare and high-hat. Use the Tri¢Xpanders to isolate your microphones during the recording process to eliminate external noise bleed and filter those undesirable external overtones.

Used as sound isolation platforms for mic stands, floor toms, or cymbals, Platfeet absorb structural borne resonance before it ever reaches your microphone.

ISO Series products from Auralex are designed to help isolate monitors, amps, microphones, and stands in your recording studio from hard surfaces. This improves the performance of your equipment and prevents vibrations that create unwanted sounds in your space. Pick up an Auralex Audio Engineers Pack today and take the first step to tuning your room.

Comments about Auralex Audio Engineers Pack:

Just to talk about price, the gramma included in this kit alone costs $55(sweetwater/amazon) and the mopads are $45. Thats already $100 without counting the other 7 items. I am not a professional engineer(Studying to be one) and the mix that you can get even with a very low budget recording equipment is phenomenal. the amp sound is completely rebalanced with the help of the Gramma and the tri-xpanders and trap-xpanders help cut of unwanted sound from drumming mix either to stop cymbal bleed and trap snare mix. also you can isolate your vocals. the mopads when i placed on my KRK's i noticed deep richer bass and higher crisper mids. i would have easily paid $100 for this.
