Title: Hi Frequiency "Hiss" when it is at pre mode
Post by: ktziavos on October 08, 2025, 09:08:02 PM

Hello there! Perfect sounding Eq! Have a small problem with the eq that i want to solve cause i want to use the pre mode. Yen i am in xlr mode everything sounds good. When i turn it to the Pre mode, sound is the same like in xlr but it adds a hisss (hi frequency noise) and it is unusable. Any idea?

It seems to be a gain staging problem.
Try increasing the gain at the preamp, via the gain switch and decreasing the level with the trim pot.
What is the sensitivity of your converters? If adjustable try reducing it. If not possible you could also add a Pad after the preamp.
