DIGITAL INTEGRATED CLASS "D" AMPLIFIER AND MASTER CLOCK SIGNAL GENERATOR
High efficiency class “D” digital power amplifier
for pure sound quality.
The AZ-1 features high precision D / A conversion and clock processing technology which evolved from our flagship models P-01 transport and D-01 mono-block D / A converters. The AZ-1 also features a high efficiency WB transformer for its power component, providing very low current loss offering excellent instantaneous "power on demand.” The AZ-1 provides high end Class D power amplification and a very natural sound with excellent resolution, imaging, density, and musicality.
WORD SYNC OUT terminal
The AZ-1 integrated amplifier is equipped with a WORD SYNC OUT terminal to synchronize its master clock operation to any optional device (Such as the SZ-1 or the AZ-1), having a WORD SYNC IN connector. The master clock in the AZ-1 outputs a signal accurate to +/- 1 ppm. This synchronization between components improves the systems playback imaging, signal clarity, staging and transparency. This results in improved audio and video reproduction.
i. LINK terminal
The AZ-1 can connect to the UZ-1 (or other I Link equipped devices), by using I. LINK (AUDIO S400) terminals. i.LINK connection enables digital signal transmission of multi-channel Super Audio CD and DVD Audio tracks. This “jitter less,” signal transmission is supported by Esoteric’ s new flow-rate-control technology which contributes to a natural and upgraded sound quality.
WBT speaker connection terminals
The AZ-1 is equipped with WBT-0735 double pole speaker terminals for secure and high quality speaker cable connections. WBT is an engineering innovator based in Germany whose products are used worldwide to provide better signal contact between amplifiers, speakers and other connected devices.
Phono input terminal
The AZ-1 features a conventional phono input terminal for excellent vinyl reproduction from analog turntables.
