DS18 DSP4.8BTM 4-Channel in and 8-Channel Out Digital Sound Processor with Bluetooth Connectivity - Water Resistant

Well worth the money. This gives me full control of my music on my Goldwing. Small light weight and the App on my phone is priceless.

Necesito ayuda con ese producto

No fault of product, it does what it's supposed to do. Used for 2 weeks, no complaints on performance, but purchased another dsp from a competitor because of more functionality and it was actually cheaper. My only complaint is it that tuning is done thru app only. I would prefer the app AND a PC based program. There's alot going on and a PC program would have made it a keeper.

Good quality and good sound make this a great item. It does everything it says it will. Being waterproof is a great making it excellent for motorcycles, ATV, boats etc. Just a great product. :)

Sadly, no matter what I did this DSP introduced clipping to the signal. It showed this clipping on the unit itself and I verified with an SMD amm1 and a o scope. My input signal was verified clean going into this unit I tried to lower the master gain input gain output gains nothing helped spent hours and could not get it to not clip the only way to get no clipping is the lower it so much that the preamp output voltage was like .2 Volts. It’s too bad because it’s a nice looking unit and the app is excellent, but unusable with all this clipping.

This sound processor makes a big difference in my polaris slingshot sound system. The best thing is that installation is easy, and I can control it with bluetooth unlike other brands. Also, since it's water resistant, I still can wash all interior of my slingshot with water and nothing happens.

No matter what I did the audio using this was horrible compared to not using a dsp at all. Even with no eqs adjusted or any adjustments whatsoever the audio output sounded realy bad. Went back to no dsp and sounds great again.
