Key Info
Gig & Recording, Amp & Monitor, Modulation Attenuator acoustic device used to float amps or loudspeakers.

 The Auralex Gramma (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.


Your loudspeakers are the most critical components you use to verify the quality of your work or to enjoy the audio you are listening to, and your guitar amp is of the same regard. No matter how good your mixer, mics, pre-amps, cables, amplifier, surround sound system or visual display, you're not truly hearing what your recordings sound like until you isolate your monitor or amp from their environment. Bass frequencies and other harmonics can be emphasised by resonance and conduction through untreated materials, which can be very problematic when trying to evaluate a recording or performance.


This is where the auralex gramma comes in. The gramma isolation pad provides sonic isolation between your speaker or amplifer and whatever surface they are resting on, instantly improving the accuracy of your entire monitoring system. The gramma pad is affordable, easy to implement and really effective at decoupling your monitors from your room and all its contents. The gramma isolation pad is suitable for speakers and amps of all sizes, and will sit firmly on any flat. For production and professional recording, this is essential. With your monitor speakers and amplifiers likely to take up a chunk of your studio or production budget, it's well worth ensuring they perform to their optimum levels.
