Hiss in Hypex PSC2.400

[momomo67890]

i have a 103 db tweeter hooked up to a mini dsp 8x8 and if i turn the volume down -24 in the software i can barely hear the hiss @ 5ft.

Again...the easiest solution is to reduce the gain in the HF channel. The so-called-noise-problem is due to the used DSP nothing else. Probably we can help by modding the HF channel.

Hi Jan-Peter,

The manual of the current PSC2-400 states that there are special jumpers that can be removed to remove 10dB to the HF channel.

Looking at the PSC2-400, those 4 jumpers appear to be small solder leads that need to be removed.

What is the preferred method for an inexperienced user to remove them without damaging anything?

Can anybody tell me if those jumpers can be safely removed?
