AMPLIFICADOR INTEGRADO 2
X 140 W A 8 Ω |
The core of the E-series is the
POWER PLANT Balanced, an integrated amplifier which simply exudes power
and offers wonderful sound. Following the tradition of our legendary
transistor-based and valve-based amplifiers, the pre-amplifier was
developed from the outset with a clear emphasis on sound quality,
neutrality and maximum possible dynamic range. The use of the latest
audio operational amplifiers on separate voltage-stabilised circuit
boards (OAD = Op-Amp Decoupling) produces a further important
improvement in the sound. As you would expect, there is a two-stage
volume control with precision ALPS potentiometer, which helps to
ensure a generous overload margin and high signal : noise ratios. A
Flat switch is included, allowing the sophisticated tone controls
and loudness function to be removed entirely from the signal path if
required.The POWER PLANT balanced is equipped with high-quality
balanced and unbalanced inputs. The balanced input section (XLR) is
located on its own circuit board, is of fully symmetrical
construction, and is coupled directly to the pre-amplifier via the
highest-quality differential amplifiers. The RCA and XLR inputs are
very flexible, and can be assigned to a variety of source devices.
The input select switches feature the best quality gold-contact
relays to guarantee freedom from harmonic distortion and background
noise.The output stages are switch-mode circuits in which the output
signal is generated by a large number of very short positive and
negative pulses. Our switched output stages - developed entirely in-house
- are by no means ready-made “off-the-peg” integrated IC amplifiers;
they are of discrete construction, and equipped with the very latest
ultra-fast MOSFET transistors and intelligent high-current driver
modules. The oversized analogue mains power supply, with toroidal
transformer for low leakage fields and separate buffering for each
stage, ensures that the system has high reserves of energy at all
times, and is the key to the enormous dynamic range of the output
stages.
External connection
The Power Plant provides five high-quality inputs, which are
selected using gold-contact relays; two of these can be set up as
XLR inputs. A1 can also be converted to a Phono input using an
internal PHE MM or PHE MC R-Series module (earthing clamp present).
REC OUT and PRE OUT are also provided. The robust loudspeaker
terminals are gold-plated and contain no ferro-magnetic metals. The
integral RS 232 socket is used for software updates, and also
constitutes the control interface for the system. For the E-series
we developed a high-performance “E-Link” bus system which passes all
commands from the FM100 system remote control handset from the MUSIC
PLAYER to the POWER PLANT. If the POWER PLANT is operated without
the MUSIC PLAYER, an FBS FM100 remote control set is required in
order to control it remotely; in this case the E 2000 IR receiver is
connected to the RC IN socket.
Technical highlights
The basis of our new amplifiers is a type of output stage known as a
PWM circuit (PWM = pulse width modulation), with a modulator of
analogue construction. The output stages feature analogue negative
feedback which compensates for any adverse effects of voltage
fluctuations in the mains power supply, thereby eliminating signal
distortions induced by the power supply voltage; such distortion is
otherwise inevitable with pure “forward concepts”. The negative
feedback is at a relatively low level, and is also frequency-dependent
(stronger in the bass range, where large currents are encountered,
diminishing in the mid-range / treble area).
This results in a very well
controlled, open sound image which never tends towards harshness,
coupled with beautifully contoured, well-defined bass. The
liveliness and musicality of this circuit philosophy is outstanding.
When designed properly, switch-mode output stages can not only sound
superb, they are also capable of generating enormous power with
greatly reduced losses and little waste heat. They cope effortlessly
even with power-hungry loudspeakers, since the POWER PLANT balanced
delivers peak currents of up to 50 Ampere.
