FAQs

Please read our FAQs page to find out more.

Stereo Mode

Replacing the op amps for both left and right channels in stereo mode, regardless of RCA or XLR inputs, will notably enhance sound quality.
Mono Mode: Only replacing the op amps for the right channel.

XLR Input

Using XLR input mode allows for further sound quality enhancement by replacing the op amps for the XLR channel.

Subwoofer Channel

If a subwoofer is connected, there's the option to replace the op amps responsible for the subwoofer channel.
Note: Carefully align the notch/the number '1' on the chip's cover with the 'O1' mark on the PCB.

Why does the BT30D Pro get hot when using a 48V power supply?

If you plan to use a 48V power supply, active cooling (such as a fan) is required to ensure stable operation. You can also attach an aluminum heat sink: learn more.

Just plain works

Don’t really write reviews, so simply put, it does what it states with zero fuss. Only improvements…In my scenario I still need an AirPlay adaptor. Bottom line for me; it’s a great solution and relatively inexpensive compared to competitors.

Clean Sound - small Footprint

Variable Tone Controls let you Contour the Sound for Mains and Sub very well
(Tested with a pair of EV Mains 15” plus Horn 8 ohm cabs and B52 18” sub cab 8 ohm also. Sounded great & clear tones. It was hot outside and amp got warm but that would be understandable at higher volumes with so large of a system being tested )

Wrong Power Supply

I just received the unit after paying customs duties and sadly it was shipped to Indonesia 🇮🇩 with a United Kingdom 🇬🇧 Power Supply. This should be an obvious quality control issue. I will have to use a travel adaptor 🥲

Shipping taking forever.

It’s been nearly 2 weeks, I have not received my shipment of the product. I’ve been checking the status and it’s been in transit for days.
