GENERAL Congratulations on your purchase of the Audio Note I Zero amplifier. The I Zero is stereo integrated line amplifier with an output power rated at about 8 watts. We choose to use the now little used triode pentode ECL82 which was widely used in small radios and early televisions as an output valve, the ECL82 is run in Class A until 80% of its rated power and close to max power I Zero switches to class AB, which provides low-heat, reliable and long life.
CONNECTIONS - INPUTS Four line inputs are available for connection to CD, AUX1, AUX2 and Tuner. All four inputs have the same specifications and can be used as line inputs for CD, DVD players, Tape recorders, VCRs etc. CONNECTIONS - SPEAKERS Each channel is equipped with 2 colour coded binding posts for connection to your speakers. Looking from the front of the amplifier, the 2 binding posts to the left are for the left channel and the 2 binding posts to the right are for the right channel.
TECHNICAL OVERVIEW The I Zero meets the requirements of Level Zero and the basic technological requirements of all Audio Note™ products. Audio Note™ use a technique called “Comparison by Contrast”* during the development of our products. This method of aural evaluation is a system currently unique to Audio Note. High quality parts are used throughout the amplifier. The circuitry is simple and incredibly effective, yielding a high level of sonic performance.
