Re: Radial J48 more noise than Hi-Z Input?

Should I contact Radial about this and ask? I imagine they'll be as bamboozled as the rest of us... but before you do that, you didn't answer one of my previous questions which was whether you had the ground lift switch activated on the J48? That could make a lot of difference to the noise you're g...

Re: Radial J48 more noise than Hi-Z Input?

The Radial D48 is an active device and needs phantom power to function which might explain why there is no noise when phantom power is off. The problem is likely due to a lack of a low resistance earth path which running the MBP on batteries does nothing to remedy, try connecting the chassis of the...

Re: Radial J48 more noise than Hi-Z Input?

The Apollo is connected to my 16" Macbook Pro 2019. Hmmm. As Wonks suggested, the problem is likely to be an absent ground since, AFAIK, most macbook mains power supplies are double insulated types. Is anything else plugged into the Apollo, like powered monitor speakers? No, nothing, except my...

Re: Radial J48 more noise than Hi-Z Input?

Also, have you tried using a different guitar, guitar lead and XLR-XLR cable, just to rule out any of those as causing the issue? I presume the recordings were done prior to adding the Fortin Cali plugin? Add a hi- gain plugin that may be adding 60dB of gain to any input signal and the background n...

Re: Radial J48 more noise than Hi-Z Input?

What is the Apollo connected to? A lot of noise issues are caused by using laptops with no or high resistance ground/earth paths due to double insulated PSUs. This stops the normal screening properties of cables from working correctly, with a resulting increase in noise pickup. The Apollo is connec...

Re: Radial J48 more noise than Hi-Z Input?

BTW, what are you trying to accomplish by using the Radial? I got the Radial to use it like any other DI box, and I use it when I only record DIs because I dont like the thought of having 2 different signal chains for DI sounds. This is the first time I ever noticed that the Hi-Z input has much low...

Re: Radial J48 more noise than Hi-Z Input?

The Twin manual states that the preamp has a 20db pad. Try not padding the Radial and use the Twin pad instead. This reduces the noise floor and changed the tone a tiny bit, but I'm not sure yet if I find it better or worse. I know from the Periphery 3 and 4 documentaries that they recorded guitar ...

Re: Radial J48 more noise than Hi-Z Input?

I'm struggling to believe the J48 clips but the Apollo DI doesn't. Are you sure its not the apollo mic input that's clipping? Well yeah, when the 15dB PAD on the J48 is NOT engaged, then the Apollo Mic input clips very easy. How can I see if the J48 clips or not? Sorry if this is a stupid question.

Re: Radial J48 more noise than Hi-Z Input?

Thank you guys for your responses! The Bareknuckle Brute Force Pickup is a High Output pickup. It will clip easily if the 15 PAD is not engaged. I also measured the noise floor: -34.6 for the J48 and -54.9 for the Hi-Z input (put through the Amp Sim plugin at high gain, of course!). Gain difference ...

Radial J48 more noise than Hi-Z Input?

Hi people, I need some help figuring out why my Radial J48 has such a loud noise floor compared to the Hi-Z input of my Apollo. I don't know much about electricity stuff, so explain stuff to me like I'm the moron that I am lol. I made a small test, where I recorded the noise I get, first half of the...
