Quad 909 Amplifier in PROSPECT, South Australia for sale

Quad 909 Amplifier A STEREO POWER AMPLIFIER from one of the world s most respected audio companies! Originally founded by Peter Walker a brilliant pioneer in the early British hi fi industry Quad continue to produce class leading audiophile equipment at reasonable prices. Quads 909 is based on experience learned from over 40 years producing solid state amplification. It incorporates Quad?s patented current dumping technology which eliminates many of the problems associated with transistor amplifiers giving a consistent and predictable performance without a need for the fine tuning adjustments on the production line. In current dumping amplifiers there is a very high quality low power output amplifier and a very high power output amplifier whose performance is not critical. This high power output amplifier controls the loudspeaker at all times and provides the current or ?muscle? to generate the sound. The low power output amplifier is arranged to generate a signal that compensates for errors between the input signal and the signal fed to the loudspeakers. The result is that the quality and accuracy of the output signal depends only upon the performance of the low power amplifier. In the 909 this low power output amplifier has been engineered to the highest standards. The problems of crossover distortion; quiescent current adjustment; thermal tracking and transistor matching all disappear. Maximum Power Output 140wrms (8ohms) 250WRMS (4ohms). Maximum Output Current 11 Amps peak each channel. Total Harmonic Distortion 0.02% (100w into 8ohms; 20Hz 20kHz). Frequency Response 13Hz to 40kHz (+0dB 1dB). Dimensions (HxWxD) 140x321x240mm. Finish silver. Warranty 1 year. RRP $2999. Save $1000! We are clearing our demo unit for just $1999.00 Challenge Hi Fi Stereo Pty Ltd 88 Prospect Road Prospect PH 1300 704 034
