Introduction

Congratulations on your purchase of a Furman Model SP-20AB you have chosen an extremely versatile general purpose power amplifi er. The SP-20AB is a compact 20 watt per channel stereo amplifi er capable of normal

stereo, two channel mono, or single channel (bridged) mono operation. It is intended to pow- er speakers or headphones with equal ease. The SP-20AB is fully protected against thermal overload and can withstand a short circuit on either or both outputs for an indefi nite time without damage. Additionally, the SP-20AB’s advanced toroidal transformer assures reduced electrical hum and mechanical noise from the unit itself. This minimizes leakage into other nearby sensitive equipment, such as mic preamps, video monitors, etc.

The SP-20AB is expected to fi nd application in recording studios (for driving small near

field monitors and/or headphone systems), in distributed commercial sound installations, for powering high-frequency drivers in bi-amped or tri-amped PA systems, and wherever a requirement exists for compact, high quality, moderate power audio amplifi cation.

Description

The SP-20AB Stereo Power Amplifi er is a unique and economical 20 watt per channel stereo amplifi er. It may be operated in any of three modes as selected by a rear-panel switch: normal stereo, two channel mono, or single channel (bridged) mono. The latter mode allows a power output of 40 watts provided the load is 8 or more ohms.

The SP-20AB is housed in a half single-space rackmount chassis. The SP-20AB can be mounted in a 19” rack by using the Furman HRKIT-1 rack mounting kit or side by side with another SP-20AB using the HRKIT-2 rack mounting kit.
