Super powerful
This DSP performs very well. It has a 32-band graphic equalizer for the main inputs (4) and a 16-band parametric equalizer for each output (8) for each speaker. Think about the amount of control you can have. 1- I matched my voltage for the outputs and inputs correctly. 2- I did the crossover cuts. 3- I flat-eq the system with a little bump in the low frequencies. The results were truly remarkable, with the system delivering an incredible sound. 4- I could tweak every speaker to my liking, and the result was phenomenal. One more thing: It produced almost 5 volts out with no distortion whatsoever, and my amps are running super cool. My sub gain is set at about 11 o'clock, and my front/rear at 9. Even if you are off a budget, I recommend this unit. The Bluetooth connects super fast, the app is very user-friendly, and it has a limiter, master gain, channel gain, time corrections, you name it. This is a super unit. It is 100% recommended.

Incredible value.
I'm using this with the AEDIKO "AC to DC Isolated Power Supply Module 110-245V to 12V Power Supply Module 12V 6A 70W Isolation Power Module with Overvoltage Overload Short-Circuit Protection" to DSP my theater subs. I'm feeding the sub outs (2 for now) from my Anthem MRX1140 to this device and then sending it to a Crown XLS2002 amplifier. It's wild that you get 4 ins ( labeled a,b,c,d for some reason) and 8 outputs ( Labeled 1,2,3,4,5,6,7,8) I'll amend my review if this product doesn't last a year but for now I'm stoked. **Note, Had to download the app from the website (qr code in the box) which required turning off auto blocker. Turned it back on once the download was completed.

First dsp it’s great so far!!!
My first dsp and I love it so far!!! Once you get used to the app the tuning is amazing!!! Sound good no noise it’s easy to install and for the Bluetooth part that every one it asking yes it does Bluetooth for tuning and streaming music you just have to put the Bluetooth input in the channel routing on only thing I don’t like is to my knowledge it doesn’t state why Bluetooth it has but the Bluetooth does work and the turning is great!! But the lack on information for the product is what I don’t like I put mine on a cooler build I’ll put some pictures (not done yet)

DOES NOT WORK WITH IPONE AND ANDROID US BASED PHONES!
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!

Amazing product when you figure out the software.
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!

Really tuned my system
Oh yes. This is really deal. Sound quality is just awesome. I had used stetsom Bluetooth dsp before this and it sounds terrible. Just alone using this fixes audio quite a bit but remember you have to play with it and your EQ to get it just right. I was having distortion on my sub channel before and this fixes that by letting me cut off certain frequency. And yes you get 4 in 8 out channels 31 bands EQ AND 31 bands parametric EQ per channel. You don’t get 31 parametric EQ in most DSPs at this price range for all 8 channels. Really allow you to dial in. Build quality is also nice . You get shinier front side with clip for left and right channels. Also 8 limiter LEDs that also serve as clip when limiter not used. I’m using this for 4 channel amp and 2 skar evls 12 alongwith pioneer headunit. You also get a sticker with it. Packaging also feels premium. Overall fully satisfied.

A great deal at under 200 for a DSP
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.

Wont connect (update below)
Not able to get it to connect to my android so far. If I figure that out I might change my rating Update: bought an iPhone 6 on ebay for $50. Download provided the app, but it didnt work. I typed Marts in the app store and Marts digital popped up. I downloaded it and picked a model with 4 inputs and 8 outputs, and it worked. This dsp model is not an option when setting up the app. Just pick a 4 in 8 out and if it has an x, even better.
