Furman Stereo SP-20AB Amplifier in excellent condition from my non-smoking recording studio. Includes rack ears HRKIT-1B for mounting this half-rack unit in your standard 19" rack. (1RU).

The is a compact, half-rack stereo power amplifier designed for recording studios. It delivers 20 watts per channel into 4 or 8 ohms, and can drive small reference monitors or headphone distribution systems. This unit was primarily used for headphone distribution in my facility, using Furman HR-2 remote headphone stations.

No rack rash.

Before listing, I have personally tested this unit for both headphone output & speaker outputs, and it is 100% functional. I buy/sell honorably & expect the same from you. Thanks in advance.
