FURMAN SP-20AB Stereo Power Amp, 20 Continuous Watts/Channel
The SP-20A Stereo Power Amplifier is a unique and economical 20 watt per channel stereo amplifier. Its toroidal transformer delivers ultra-quiet performance, making it ideal for recording studio applications. The SP-20A 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 later mode allows a power output of 40 watts provided the load is 8 or more ohms.
The SP-20A is housed in a compact, half rack chassis, allowing it to be mounted either alone or side by side with other SP-20A's in a 19" rack. Mounting kits are available from Furman. The SP-20A's small size makes it ideal for modular use in large commercial installations with multiple small speakers. Its power capacity is also just right for driving the small "cube" reference speakers used in most recording studios as a comparison with the main control room monitors - it can power them without overpowering them.
