HUM Audio Devices RP-2 is transformer balanced, fully discrete Class-A design equipped with remote controller. The connection between preamp box and controller requires only one standard XLR cable so it’s very convenient in use. Gain circuit uses photo cells to control the levels so there is full separation between audio path and remote signal.
RP-2 preamp offers massive, dynamic sound with lots of sonic details.
It’s great for all types of mics, especially ribbons because of very low self-noise.
