Marts Digital 8-Channel Output 32 Bit 96kHz Bluetooth DSP BTX8-DSP

This is AMAZING, small but mighty. I was able to tune all my amps including the base. Love it.

After several months of research/review watching, the MARTS BTX8-DSP came out as my top choice amongst entry level DSP for car audio. The 4 INPUTS and 8 OUTPUTS was a key feature for retaining fade capabilities.Connection via Bluetooth is effortless. The app controls for setting channel routing, gains and crossover points are very responsive while the EQ section could be a bit more refined as making settings isn't as finely tuned. My DSP is managed via a Galaxy phone, so the controls may be better on a device with more screen real estate.There are other DSPs that run similar software at about $80 but most of those DSPs are limited to 2 INPUTS. For $160 this DSP gives you a lot of functionality that you find in higher end units (Audison, Audio Dynamics etc) cost several hundred dollars more.IMO this is a great unit to add if you're just getting into DSP. This is a budget DSP that doesn't perform like typical budget gear.If I hadn't already committed to an Audio Control DSP Amplifier for my other vehicle, I would seriously consider going with the MARTS BTX8 again.

Do not but this if you live in the USA. The software for the Bluetooth will not connect to your phone. This product is produced in China and its not compatible for US phones software. I spent days trying everything to get my Iphone and my android phone to connect to the Bluetooth. I also contacted Big Jeff the seller of this pos! His team had no clue on how to correct or upgrade the firmware to work on American based phones. I should get paid because im the one that did the research and finally found an answer from the manufacturer. I was also told no you have to use a different app thaen the one it says to use in the qp still did not work. I cleared my cash on both phones when I swapped the software think that would help! No luck and very disappointing because it seemed to be a good dsp if it would have worked. It sad that Big Jeff and Amazon would know this was an issue. You get what you pay for. Stay away from all Brazilian designed dsp because you will have issues getting it to work. Plus the only way to setup the dsp,is through the BT app. The should give you an option to plug into the app with your laptop but they dont! STAY AWAY FROM THIS DSP!

This device is outstanding

Why did you pick this product vs others?:For $170 this is a ton of functionality in a very small package. If you’re in the market for a DSP but don’t want to shell out $550 for a helix mini this will get you a ton of features for a fraction of the price. Make sure you use the marts digital app to connect with the device, it allows you to actually use it. Time alignment, 31band eq on each speaker and the main channel, etc etc etc it’s so so powerful. AND CHEAP. And small!
