Infinity Beta Digital 50 high quality USA made amplifier from the 90s. Very clean sounding and beautiful looking. Innovative differential amplification output switching is the design essence of these amps.High power digital to analog converter on each channel to directly convert digital signals into amplified analog audio waveforms. Custom designed high speed MOSFET switching power supply to supply voltages for internal circuits. High efficiency design requiring far less electrical power and generating less heat. Unibloc chassis design provides improved heat-sink capacity with exceptional sheilding characterstics. Power output 4 ohms; 2 x 50 watts 2 ohms; 2 x 100watts Bridged 4 ohms; 200 watts Frequency response 20hz-20khz +0/-1db Equalization 40 Hz, 0~11db gain Input Sensitivity 250 mV~9v THD = Noise(4ohms): < 0.2 Signal-to-Noise >90db Max. current draw >25A dimensions 9.5L x 8.5W x 2.25D inches

INFINITY BETA 10 / 20 / 40 / 50 / C250 / C360 CMMD 1 TWEETER DRIVER # 351372-001.a CAME OUT OF A BETA 40 LOUDSPEAKER, (HAVE 2 AVAILABLE, OTHER IS SAME OR BETTER CONDITION, ALSO TESTED WORKING PERFECT) DRIVER WAS TESTED FOR HIGH FREQUENCY 70 DB SWEEPS COVERING 5000HZ - 16000HZ AND PROVED WORKING AND SOUNDS NORMAL. SHOWS VERY SMALL MARKS ON THE TWEETER WICH WILL NOT AFFECT PERFORMANCE IN ANY WAY, OTHERWISE GOOD FUNCTIONING SHAPE. 1 CMMD HIGH FREQUENCY UNIT, WILL WORK IN ANY BETA SERIES SPECIFIED LISTED ABOVE. WILL BE CAREFULLY PACKED FOR SAFE TRANSIT. NO REFUNDS. LISTING IS FOR 1 SINGLE TWEETER UNIT , CAN BUY BOTH HOWEVER FOR DOUBLE THE PRICE, PLUS SAME COST SHIPPING. THANK YOU
