Powerful and convenient

This DSP has all the features you would expect from a DSP but its so convenient with the ability to control and monitor everything from your phone. My favorite features are the voltmeter, limiter and gain controls at your fingertips. It's also cool to be able to see the actual cutoffs of the crossover on the screen.

Great Tool

This is super easy to use, but it will not work from very far away ! you still need to be 25ft close to the car

Dsp Bluetooth

This thing is awesome. Control all your eq settings right at your fingertips. Thanks Timpano audio. I look forward to using more products in the future.

Top Tier for sure

This little product pack a real punch, it really cleans up your audio, separates mid bass from vocals and vocals from highs I would recommend this item to anyone looking max output and performance from thier sound system. Only downside I would ask that the timpano company do a small video on how to install and operate this unit. Then it would be a 6 star ⭐ product.
