Hey everyone,
I had purchased an amp+dsp called the "FXtreme DB450" from a user on this site named Prinkiestonkie. I had originally found him on Instagram. I've had the amp for a while and have only recent gotten a chance to make something and utilise it. However, I am a noob when it comes to trying to program the DSP. I've done some basic tuning on my Helix DSP in my car but I can't even get this amp+dsp connected to my PC. The amp was shown off in this forum here but the user has been banned, his website is down, he is not replying to his instagram comments or DMs and all youtube videos have been made private which leaves me in a pickle. Just wondering if anyone can help me get this set up. Here are some of the features:
-8-24v input voltage (4s/16.8v Li-Ion battery or 19v 4a PSU Recommended)
-CSRA64215 Bluetooth 4.2 AptXll <40ms TWS + 8DBi antenna (30m/100ft+ Range)
-ADAU1701 fully configurable DSP (SigmaStudio on PC/Mac required for programming)
-TPA6132 Opamp (Balanced)
-AD8608 Precision Opamp
-LTC1871 Step-Up Booster (Adjustable from 8-24.5v)
-2x TPA3116D2 Amplifier chips (4-8Ohm // 2-4Ohm Mono-Mode)
I can't even find the correct programmer to get this connected to my PC and I don't have a base file to go off for SigmaStudio so any help is appreciated. It would have been great if I could message anyone from the forum post linked above but I can't unfortunately.

You are in a tough spot. For information on USBi programmers see this THREAD. Getting the programmer to work can be the hardest part. There are a couple of reasons why:
1. The driver isn't signed so by default Windows won't load it and you have to take special steps to coerce Windows. Carefully read and follow the FreeDSP information (LINK) - it has the steps you follow to force windows to load the driver.
2. Once the driver loads it has to download a file named ADI_USBi.spt to the CY7C68013A mini board in the programmer. This file reconfigures the mini board so SigmaStudio recognizes it. If the driver can't find the file the programmer won't work.
There are also some programmer's that I call "all-ini-1". The firmware in the mini board is updated so downloading the ADI_USBi.spt isn't required. I always recommended the SigmaLink all-in-1 programmer, but it's currently out of stock.
Here's a few links for SigmaStudio information:
SigmaStudio WIKI, Part 1 of a 7 part SigmaStudio tutorial by EMUMANNEN, Engineer ZONE forum (you need to join and select the "SigmaDSP Processors & SigmaStudio Dev. Tools" forum.
- You can save (in binary form) the existing program from SigmaStudio. In the Hardware Configuration tab, right click on the EPROM and select "Read/Write Window". You can download the program to a file and later upload it to the 1701. Note that this file is binary only and it won't show up as a schematic.
- IIRC that amp is Bluetooth only. If the Bluetooth module is outputting an analog signal then you would select the 1701 input channels 0 (left) and 1 (right). On the other hand if the Bluetooth module is outputting a digital (i.e. I2S) signal you'd use 1701 input channels 1 and 2. I don't know which way the amp is wired up.

Once you get SigmaStudio running:- You can save (in binary form) the existing program from SigmaStudio. In the Hardware Configuration tab, right click on the EPROM and select "Read/Write Window". You can download the program to a file and later upload it to the 1701. Note that this file is binary only and it won't show up as a schematic.

The website is gone,...but not forgotten. The google share is still open so you can still get the only 2 files that were provided. I don't use Sigma Studio so I can't help there.
