Cambridge Audio 350A Musical Instrument Amplifier User Manual

Thank you for purchasing your Azur 350A. We are confident that you will
enjoy many years of listening pleasure from it. Like all Cambridge Audio
products, the Azur 350A adheres to three core principles – stunning
performance, ease of use and incredible value.
The design of a high quality but cost-effective audio amplifier presents a
major challenge. Providing first-class performance on an unlimited budget
is one matter; achieving the same performance within tight price limits is
quite another, and requires the expertise and experience that Cambridge
Audio brings to its product design process. We believe we have succeeded
in our aim of creating a first-class affordable amplifier.
In this product separate very high quality Integrated Circuit Amplifiers
modules are used for each channel for freedom from crosstalk and best
possible stereo imaging.
Close attention has been paid to the performance and quality of the
passive components, both in the signal paths and for decoupling
purposes. A Very high-quality black box film type volume pot from ALPS
has been specified for its superior sound quality and excellent channel
balance.
The power supply is also a vital part of any power amplifier. A toroidal
transformer, selected for low external magnetic field, is used in
conjunction with generously specified reservoir capacitors and optimally
placed decoupling components.
The 350A incorporates tone controls that give subtle control of the
frequency response, allowing the correction of imperfect source material,
and compensation for loudspeaker inadequacies or problems with room
acoustics. These tone controls can be switched completely out of the
audio path by use of the DIRECT switch, to give the shortest possible
audio path.
The 350A has full protection against misuse and possible faults. The
overload and short-circuit protection systems continuously monitor the
voltage, current and temperature of the output devices, allowing the
protection to act positively in case of need, without triggering spuriously.
Our a new casework design is featured with a thicker braced front panel,
more rigid wrap-over lid assembly and dual-layer damped feet, all of which
contribute to better resonance control.
An MP3/Portable Media Player input has been fitted to the front panel for
convenience, and the supplied remote can control the amplifier, any of our
matching CD players and basic functionality of iPods in our own or Apple
docks.
Your amplifier can only be as good as the system it is connected to. Please
do not compromise on your source equipment, speakers or cabling.
Naturally, we particularly recommend models from the Cambridge Audio
Azur range, which have been designed to the same exacting standards as
our amplifiers. Your dealer can also supply excellent quality Cambridge
Audio interconnects to ensure your system realises its full potential.
Thank you for taking the time to read this manual; we recommend you
keep it for future reference.
