Boostaroo Post Amp

SKU: 3075

Availability: In stock


Product Description


Many personal players do not provide quite enough volume to blast over wind noise or past earplugs. The Boostaroo can help. Plug it into the audio jack of your radio/scanner/whatever, then connect your helmet or earplug speakers. Voila, the sound level is increased by about a third. Input device volume adjustments remain functional, but everything tops at a greater volume. Clearly and cleanly, too. About a 12dB gain in a typical ear speaker. Two AA batteries (not included) last about 20 hours. There are two jacks so a passenger can listen along. 40mw per channel.

I recently purchased this to use in conjuction with my XM "Roady XT". Clear sound with no distortion in the background. Fits compactly in my tank bag. (Posted on 4/28/09)

I've placed this onto a Honda Big Ruckus equipped
with dual battery charging system and an aux. battery Odyssey PC-680 (fits the BMW K-75s that needs the tranny put back in, etc) to power up three amps (30 w. for small front speakers [Poly-Planar 840 b], 150w for mid range rear speakers [Poly-Planar 5" , 200w for marine grade sub woofer [ms55 from Poly-Planar]) and will be installing a capacitor for the power amp of the sub-woofer soon.

Without the pre-amp in the Circuit it's just not quite
audible in a tunnel next to a truck. With the pre-amp in
it's louder than the trucks and most Harleys!!!

The scooter's sound system and the music I play on it made the local rag. You can see the article at:

The scooter earned two trophys at rallies, so far.

Using one of these pre-amps on it; just wanted a working spare. I'm anal about spare parts!! (Posted on 4/28/09)

...not quite as good as the super booster, but worth the price. Great for listening to movies on a plane with a partner. Great battery life, but the lack of volume control is where this unit falls short. I'd give it a 3 out of 5 :) (Posted on 4/28/09)
