Elector Analog Preamplifier

The Elector is based on the Director Mk2 and designed as a
pure analog preamplifier.

It features a total of six analog inputs. Three of which are
balanced with XLR connectors. The Elector is equipped with the big remote
controllable aluminum volume control with marker LED and two mechanical VU

External audio processors or analog tape machines can be
inserted in the Tape Monitor loop.

The Elector is the pure analog version of the Director Mk2.

In case you have a DA converter for your streamer or
computer or you are not a fan of digitally stored music the Elector is the
perfect choice for you.

Tape machines and cassette recorders, record and CD players
can be connected via standard RCA sockets or via balanced XLR connectors.

The ideal completion to the Elector is the phono
preamp Phonos.

A headphone amplifier like the Phonitor xe or
the Phonitor e can be connected to the Direct Out.

And power amplifiers like the Performer s800 or Performer
m1000 or active loudspeakers are connected to the Preamp Output.


The Elector is a stereo preamplifier that provides
connectivity for six analog stereo sources.

Three of which are balanced XLR inputs and the other three
are standard RCA inputs.

Power amplifiers or active loudspeakers are connected via
balanced XLRs and a headphone amplifier is connected to the Direct Out.


Volume is controlled in the 120V rail VOLTAiR volume stage
and an ALPS RK27 “Big Blue” potentiometer with excellent feeling and
channel matching.

Being motorized Volume can be remotely controlled. Please
refer to the chapter “Remote Control” for more information.


Up to two power amplifiers can be wire-linked and triggered
for simultaneously switching power on/off with the Elector.

To achieve this connect the AMP CTL sockets with 3.5mm
mono-jack cables to the power amplifier. The Elector sends out a 12V trigger
voltage on the sockets A & B to switch one or two stereo amps or two mono
blocks on and off.

Remote Control

Volume can be remotely controlled using any existing infra-red
(IR) remote control. The cool part is that the Elector learns the remote

Take, for example, the remote control of the CD player. Out
of the many buttons there are mostly two you hardly use if at all and which do
not directly trigger a function on the CD player.

Assign Volume Up / Volume Down to two buttons and let the
Elector learn them. The procedures are described in the manual and in the video
“Learning Remote Control”.

VU Meters

The two VU meters display the source’s level. It’s
mechanical design ‘slows’ the measurement, averaging out peaks of short
duration, and reflects thereby more the perceived loudness or ‘energy’.

VU means Volume Units. A typical VU meter shows a range of
-20dB to +3dB. Our VUs go slightly above +5dB. A mastered CD can produce much
higher levels depending on the settings of the DA converter which would glue
the needles to the right side.

To prevent this the VU toggle switch set to position 6 shows
a dB value with the needle pointing at 0 of +6dB. Set to position 12 the value
is +12dB when the needle points at 0.

With the VU switch set to +12dB the VU meter can display
levels slightly above +17dB. If the needle goes beyond that it does not
indicated that the Elector is clipping. Thanks to the VOLTAiR technology there
is still more than 15dB headroom.

Tape Monitor

In the 70s and 80s cassette recorders were very popular and
a hifi equipment used to offer a tape monitor function. Later this feature went
away, but fans of recording and processing found the lack of this feature in
today’s preamps being a real drawback.

Well, we re-introduce this feature in the Elector. It is
possible again to insert a tape machine and to listen back while recording
(tape monitoring) or to insert beloved equalizers or other processing devices
to room-EQ or to tune sound.

On the rear of the unit is a level calibration switch
besides the tape send and tape return sockets. Consumer tape machines, cassette
desks or consumer equalizers may clip when being exposed to the levels that the
Elector easily handles. To prevent peaks and distortion this switch reduces the
outgoing level by 10dB and lifts it again by 10dB when coming back into the
Elector. Thereby no level difference will be audible and your gear performs on
level it can handle.
