RESTEK EDITOR Stereo PRE-AMP. High End Made in Germany.

RESTEK EDITOR Stereo PRE-AMP. High End Made in Germany.

The hi-fi preamplifier is the center of a stereo system. All external sources are managed and forwarded through it. This is done by switching the signal sources and amplifying or attenuating the output signal.

High hi-fi sound quality without distorting controls on the preamplifier

Another possible function, the interposition of different filters, was deliberately omitted in the EDITOR. The reason for this is that with a high level of the other hi-fi components corresponding to the EDITOR, filter circuits are pointless and could have a negative effect on the sound. Adaptation to the acoustic conditions of the listening room is only possible to a limited extent with the help of tone controls on the preamplifier. With correspondingly high-quality components and acoustically normal rooms, tone control is more harmful than useful.

Nevertheless, you don’t necessarily have to do without sound controls with the RESTEK EDITOR. The preamplifier offers the option of looping an external device into the signal path for room adjustment via the SPLIT function.

Nine high-level inputs are sufficient even for demanding and complex hi-fi systems

The EDITOR has nine high-level inputs. Four of them are designed as balanced inputs with mini XLR and five as unbalanced inputs with cinch sockets. Optionally, a cinch input can also be converted into an RIA phono preamplifier input.

The RESTEK EDITOR – a preamp with the latest technology

Internally, the EDITOR consists of two separate, fully symmetrical, identical mono preamps, each with two volume controls. So there are eight potentiometers in total. The inputs are switched via high-quality signal relays. whereby the ground connections of the unswitched input sockets are separated from the device in order to avoid ground loops.

The input sensitivity of each selected input can be adjusted within a range of ±6 dB to compensate for volume differences when switching between individual inputs. The signal can be attenuated by up to -95 dB or amplified by up to +10 dB using the volume control. The two outputs, which can be controlled separately from each other, can be leveled against each other in a range of ±6 dB and, if desired, can also be set synchronously with each other.

The output drivers of the preamp establish the connection to the power amplifiers or active loudspeaker boxes. The low output resistance of 50 ohms and the maximum current of up to 200 mA rms of these driver stages enables correct line matching on the one hand and on the other hand the use of sometimes unavoidably long connecting cables between the preamplifier and the power amplifiers without the music signal being impaired by the cables.

All parts of the electronics of the EDITOR are DC-coupled, which makes it possible to transmit even the lowest frequencies. This means that even in the lower frequency spectrum, the transmission is distortion-free and phase-locked. There are no capacitors or electrolytic capacitors in the signal path that could cause distortion. Noise and crosstalk can only be detected at the measurement limit.

The demand for ease of use and great functionality is realized through the possibility of operating all special functions using the remote control or a single button. The design of the preamplifier remains puristically clear, since the mature and at the same time impressive concept of one-button operation does not require any additional knobs, buttons, controllers or the like.
