EVOLUTION TUNER
One
of the great strengths of Creek Audio through the years has been the ability to
produce exceptional tuners. The Evolution AM/FM Tuner carries on that tradition.
Styled to complement the Evolution range of integrated amplifier and CD player,
this tuner is the perfect match. Although the Evolution styling is not quite
the same as the Classic and Destiny series, there are important styling
features, like the button layout, logo position and control knob details that
show its Creek heritage.
With today’s airwaves seemingly becoming even more crowded, coupled with the
ever-increasing methods of accessing radio broadcasts, why would you purchase a
dedicated tuner? The answer is quite simple – it is the only way to bring radio
broadcasts magnificently to life. Separates do sound better and a stand-alone
analogue tuner will provide a purer quality of sound.
Firstly, in a hi-fi context, most listening is undeniably FM, although this
analogue tuner is not limited only to FM. Tune-in to your favourite station and
you are instantly aware of the exceptional quality. Listening to it is
addictive, and the idea that radio is purely a source of background music,
carries no weight. The Evolution Tuner is functional, versatile, high tech, yet
simple.
The design objective for the Evolution AM/FM Tuner was to develop a product
that, regardless of price, could be a benchmark for both radio and audio
performance. By using high quality components and sensible electronic design
Creek has achieved its goal. The mixture of high technology and design
simplicity has reduced the component count to a level previously thought
impossible.
Whilst the majority of synthesised tuners today use buttons to tune-in stations
and select pre-set station memory, the Evolution AM/FM Tuner uses a rotary
tuning knob connected to a digital encoder to provide tuning and pre-set station
selection in a way that makes this digital tuner operate and feel like an
analogue tuner. To simplify its functionality, Creek’s engineers have reduced
the number of local functions to a minimum, while maintaining all the necessary
functionality. Front panel controlled functions include Rotary Tuning Mode,
Rotary Pre-set Mode, Band Switching - AM/FM, Auto Scan tuning and Memory store.
These, plus Mono, Stereo, Display Brightness and direct pre-set station number
entry are also available via a system remote control, that also serves the
Evolution amplifier and CD player. The Evolution AM/FM Tuner also has the
ability to display the name and frequency of the station tuned using RDS (Radio
Data System) on its blue vacuum fluorescent display.
To achieve high sensitivity and selectivity, the Evolution AM/FM Tuner uses a
four tuned circuit FM radio front-end with J-FET RF amplification and mixer and
is shielded from interference by a tin-plated metal can. A high-grade 10.7 Mhz
IF circuit and PLL stereo decoder process the signal.
A mixture of conventional and surface mount technology is used together on a double sided plated through-hole printed circuit board to provide a high level of interference suppression and help to achieve hi-fi levels of performance.
Station pre-sets are held in a
non-volatile memory, similar to that of a PC computer, with up to a maximum of
80 memory locations available between AM and FM. A large sized blue vacuum
fluorescent display makes it easy to read and the intuitive system remote
provides easy control of the Tuner, Amp and CD from the one handset. the open
and dynamic sound of the Evolution Tuner can be restricted by the quality of the
aerial or antenna used. In addition, the distance from the station and the
source quality from the chosen radio station will determine the absolute noise
performance.
