The core of the E-series is the POWER PLANT balanced, an integrated amplifier with almost boundless power and superb 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.

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 information
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.
