FBA-800

The FBA-800 is our most advanced power amplifier. The floating bridge design combines four 20 Watt amplifiers in a single stereo chassis and provides several key benefits. Each channel consists of two amplifiers working as voltage amplifiers driving an output stage of bridged power transistors. The advantages are a low noise floor, better power output relative to the voltage rails (x2) and with the fixed current of the class A mode, low output impedance and better load tolerance. The Power amplifier is D.C. coupled, with a servo lock, ensuring excellent low frequency detail. For safety purposes the amplifier includes a D.C. protection circuit. This circuit is statically switched using extremely low impedance Mosfet switching devices. This circuit also soft switches the power amp on and off. The power supply is a low impedance design with a single custom made bi-filar wound transformer, with four separate windings. The main smoothing capacitors for the output stage are specially developed for professional audio applications with excellent ripple characteristics and long life. The Four power transistors per channel in the output stages are multi emitter devices with an output capability of 26 amps per device. The FBA-800 operates in the full balanced mode from the input of the unit to the output Facilities Inputs​​ ​Outputs​​ ​ Front Panel Gain Selector Front Panel Input Selector ​ ​​​​​ ​Specifications Input Sensitivity​ Power Output ​​Frequency Response Bandwidth Signal to Noise Distortion at 1 Watt 1kHz Gross Weight (packed) Dimensions Stereo line level, stereo balanced Stereo pair multi-way locking binding posts ​ 6dB input attenuation RCA or XLR ​ ​​​​​​​​​ 735mV for full output 40 Watts into 8 Ohms both channels working 0dB 20Hz-80kHz 6Hz-113kHz >96dB >0.05% 25kgs 206 x 430 x 460mm (hwd)
