The SC-1mk3 Mic Preamp is a clean, "fast", clear, low-noise, high-gain preamp. Its sound is very transparent, offering a flat response, smooth highs and well-defined mids.
This is a great project for a first-time beginner to kit building. The kit is very affordable, but don't let it's low price fool you. This preamp delivers top-notch performance.
All solid-state design, using chipsets from THAT Corp and Burr-Brown
Soft-start, slow ramp-on +48V phantom power
Option to use input transformer for added sound “flavor”
Gain range from +12 to +72dB, in 6dB increments from +12db to +42dB; 4dB increments from 46dB to 72dB.
Onboard Power Supply Regulation, adjustable +/- voltage rails
Robust 48Volt short circuit protection (from accidental phantom power shorts)
LED-lighted push buttons for phantom power, -20dB pad and polarity reverse
VU Meter, 5-LED bargraph
