I'm not sure why it does this...it could be the input transformer or perhaps the tube circuit. maybe Manley built a limiter into the circuit to not kill the tube stage.... I wish someone could explain it actually. anywayz if you boost after doing this it will distort at the output stage....it seems that the input wall is right before the output clips.
Here's a partial spec from Manley's site.
• Ins & Outs Balanced XLR & 1/4" (accepts unbalanced)
• Level +4 dBu nominal, internal switches for -10 operation
• Bypass Switch bypasses EQ & tube circuits (not hardwire)
• 44 Frequencies (roughly 1/4 octave spacing)
• Frequency Range: 22 Hz to 27 Khz
• EQ Boost/Cut Range : 20 dB boost, 20 dB cut
• Nominal Q range: 1.5 to 3 (uniquely active in shelf modes)
• Frequency Response: +/- 2 dB: 8 Hz to 60 KHz
• Maximum Output @ 1.5% THD +37 dBv; +26dBv @ 20 Hz
My interface is currently calibrated to +18=Odbfs, and I have no limiting or headroom issues with my MP. It strikes me as odd that you're getting some sort of limiting out of the unit, especially that far under spec.
I've used the MP in a variety of things, on the mix bus, but I quit putting any eq on the mixbus, bass, gtrs, whatever. I really dig it on string orchestra, and synth orchestra, for different reasons respectively.
