Has this not been done before?
Probably… The real innovation with the TriPad is in the design – the way it is cut makes it easy to deploy and since it stays on the stand, it is convenient. There is nothing more frustrating than having to carefully adjust a foam isolator each time you move the stand around.
Is the TriPad foam special?
Yes and no. It is produced from high-density open cell urethane foam. The difference here is that it is thick enough to eliminate the resonance, while being stiff enough to securely hold the microphone stand. Anyone who has worked in a studio or a live stage knows how frustrating it can be to use a cheap mic stand that droops. When designing the TriPad, the idea was to make these devices so that they would provide a stable base, yet be soft enough to stop energy from transmitting.
Will using the TriPad help when recording voice?
Yes most definitely. Most singers and musicians for that matter tend to tap the tempo with their feet. TriPads stop this vibration from entering the microphone.
Can I use TriPads on a live stage?
Absolutely. They are very helpful when recording and particularly effective at eliminating low frequency resonance from traveling through the stage, the mic stand and then into the microphone.
Can you explain resonance?
When you knock on a door, the door has a sound. The fundamental frequencies of the door will be the vibrations going up and down and side to side. These are known as resonant frequencies. A drum can also be tuned to have a desired resonant frequency. They are in fact a tone or sound that is loudest within a given sound. Stages are generally made from large sections of wood mounted on some sort of frame. Because they are suspended, they are free to vibrate. This vibration becomes resonant when it is set into motion. This can be caused by the PA system, kick drum, or bass guitar when played at a frequency that is sympathetic or harmonically matched to the stage. When the wanted sound combines with the unwanted resonance from the stage, the two sounds can cancel each other out or amplify each other. This is known as modal distortion and can be very disruptive to the musicians on stage and the sound engineer who is trying to get a proper mix.
How can using TriPads help with bass guitar?
Bass guitars produce powerful low frequency waves. They cause everything to vibrate. Isolating the mic stand in front of the cabinet can eliminate the resonance from the stage from competing or canceling out bass frequencies.
How can using TriPads help with a violin?
Whether the violin, viola, cello or contrabass is being used in a quartet or as part of an orchestra, vibrations caused by feet tapping the tempo will invariably enter the microphone. By isolating the stand, you can reduce the unwanted sounds from finding their way into the most sensitive microphones.
How can using TriPads help with a drum kit?
Drum risers are probably the worst offenders of all when it comes to resonance. They are hollow boxes that will resonate from the sound of the kick drum, the bass guitar and the low end produced by the PA system. Isolating the mic stands around the kit will help to clean up the sound of the drums.
If I use a shock mount, do I need TriPads?
This depends on the microphone and source. For instance, if you are recording a fairly loud source such as a vocal, the microphone shock mount should be sufficient to eliminate any vibrations that may transmit from the floor, through the stand. This will also depend greatly on the quality of the microphone shock mount. The typical elastic suspension type work well while some of the more rigid designs may not be as effective. In either case, adding TriPads to the mic stand will improve the isolation.
