This family of chips was designed for a variety of audio applications, including 'moderate home audio products' such as soundbars. They have also found use in high-performance subwoofer applications, particularly in the low-frequency spectrum, where they excel. Audio-grade nuts will have issue...

Muddled waters. It features an ADAU1701 processor with four channels of DACs. This configuration allows for running two full-range speakers and a subwoofer setup. The product's name or marketing description doesn't impact its versatile application or configuration. In fact, I have multiple...

He asked "Secondly, is it flexible enough to be used as an EQ for subs?" So I answered.

@DeonC Here is an example of a structure for a subwoofer processor I made 3 years ago! that simulates a "typical modern subwoofer processor chain" like the SVS Subwoofer signal chain. **Subwoofer Processor Structure Example (Simulating SVS Signal Chain):** 1. Channel Summation - Combine...

Board Capabilities: The board in question is highly versatile and can effectively handle subwoofer applications for both DIY enthusiasts and commercial users. It has emerged as the preferred solution for modern subwoofer DSP (Digital Signal Processing) needs. Limitation of Sigma Tool: It's...

I'm commercially experienced in both fields with direct crossover of both subjects for the last 23 years and highly active on the ground: I would recommend Electronics Engineering with an aim to cross into Software Engineering the reason for this is today's "technically advance world the one...

If you measure out the dimensions of the SVS Ultra enclosure (which uses this woofer) and use the extract wall thickness used and bracing recommendations you won't be sorry. I actually did this using a the peerless driver (the one used in the PB Ultra) and the outcome was very impressive...

I would carefully read the warranty of each of the battery manufacturer of your choice. Here is a group discussion around sunsynk batteries. I would recommend you pair with their batteries for obvious reasons example: like the 10 year warranty...

Also the reason for active high is: the system uses logic signals which interfaces with a system using an open collector output with an active pull up resistor. There is no standard what dictates ON (0V) or OFF (+5V)

First generation UCD and REV v3 SMPS PCB, What a combo 10 years ago, These issues are eventual for the generation. But for R1500 you can get a brand new LLC power 1KW 75v from EBay. That PSU is overpriced and suboptimal for the worth today. (classic push pull with synchronous rectification)...

Calculation: The amplifier is capable of 2-ohms (maybe even 1.5) though I personally shall be using an 8-ohm load for applications that are used for movies and music with moderate playback levels that are "neighbour friendly". Amplifier output power rating is a function of the power supply...

Some will fail slow others will fail fast some will appear to work and fail much later (randomly), fake parts, lack of protection. there are some pitfalls on this amplifier known to class-d designers, these batches are sold on Ebay for years now. The International Rectifier reference circuit...

Apologies for the lack of updates, things has gotten busy... juggling life responsibilities.   After all the parts for the amplifier arrived (still sitting on my desk), I decided to address some issues that was bothering me during the initial design like protection short comings and...

There are two ways to look at this, fix it and figure out the short comings, the other way is fix it and wait again for it will blow again. The author of these module is a schematic copy cat thief on diyaudio he sells these kits on Ebay riddled with issues.

Thanks for showing interest, I was very close to closing down this thread due to lack of interest from local public. (my feeling is this forum is dominated by a vacuum tube /CLASS-AB crowd) but clearly there seems to be some hope. Q: Would this drive a 200 watt RMS speaker?  A: Yes, it would...

Nice! reminds me of the ESP 100W AB amplifiers back in the day. Great times!

For those interested in the fundamentals of the circuit please go here. Makes me proud, one of the first high class, class-d amplifier circuits was authored right here at Stellenbosch University by Kemp, Pieter Stephanus, Supervisor: Prof H. du T. Mouton, Co-supervisor: B. Putzeys (CTO at...

POST feedback with a balanced modulator.

Thanks for showing interest. - IRS2092, no. however I used IRS2092 in the past nothing wrong with it, but this time I'm a IRS20957 for level shifting, and programmable dead time control only..  I'm using my own scheme that uses a lower THD modulator scheme that's fully differential. - Max...
