Hi, 

I'd like to plug the XLR balanced output (post eq) of my BQ500 into a mixing desk (Mackie ProFX16v3), but need to enable 48v phantom power of the desk. 

Does the amp have a built-in safety to allow that? If not, can I use an XRL to 1/4 cable or another workaround? Or do I absololutly need a DI box? 

Thanks for your help! 

Regards,
Alex

Hi community,

I want so get a monitor signal from my DI out, and therefore make a cable with XLR to Jack connector. 

Can I bridge Pin 1&3 safely or will it do any harm to my amp (TC BQ500 bass head)?

Thanks in advance!

Hi there, 

I recently purchased the Thrust BQ250 Bass Head. It's rated for 250 watts @ 4 Ω. But my cabinet, like most, is 8 Ω. Now, I know the wattage will decrease significantly since the resistance is doubling, but I also know it's not as simple as cutting the wattage in half. ?

When you have more resistance the amperage goes up, and watts is volts × amps. So it's not exactly half. As with higher resistance you create more source amps and more source amps by source volts means higher watt. ?

I've read the manufacturer's product page, specs, user manual, etc... I can't find the information anywhere. I've seen other manufacturer's websites and they'll often print the watts for both 4 Ω and 8 Ω so us bass players don't have to take wild guesses or learn electrical engineering (heck we can barely count to 4 right?) ?

to;dr: does anyone know how many watts the Thrust BQ250 will output to a cabinet with an impedance of 8 Ω ?

Thanks very much in advance. ?

I was watching a review for the BH800... I assume it is more or less similar to the BH550 with only the wattage differing.

The reviewer indicated the BH800 was a class D power amp and therefore has a slower attack than other amplifiers.

I've never heard amps described that way before, can anyone help me understand what it means?
