 SPL Audio Elector 

ELECTOR...THE ANALOG PURIST

The Elector is the perfect preamplifier for the lover of pure analog technology. With motorised, remote volume control, tape monitor path, retro-look-VU-meter and the all superior VOLTAiR technology, the Elector brings analog sources to new life.

Milled from solid

The massive 45mm volume control knob milled from aluminium is a haptic highlight. Its mass together with the motorised Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further.

The red LED marker ensures visibility of the volume parameter, even in darkened environments.

Remote control

The volume control can be remotely controlled with any infrared remote control. The Elector learns to communicate with it with the simple push of a button.

Learning made easy

The video below explains how you can use any infrared remote control to remotely control the volume and the source selection.

Source of joy

Up to six (6 !) analog stereo sources can be connected to the Elector.



The Elector offers three pairs of balanced inputs with XLR jacks and three standard inputs with gold-plated RCA jacks.

Good ol' times

Two mechanical VU meters visualise the input levels for the left and right audio channel. With the VU switch you can optimise the display for different signal levels.

Tape Monitor

A tape monitor circuitry is quite retro. Who still owns a cassette recorder or a tape machine? Who else loops in an equaliser?  To put it another way, who would like to do it and cannot do it because no manufacturer offers a tape monitor circuit anymore? Well, those who want to, can, again.



Today’s audio levels are much higher than in the past and many recorders will be overloaded by them. In that case simply press the switch and the level to the recorder is lowered by 10 dB. To compensate, the level from the recorder is increased by 10 dB. Et voilà.

Everything under control – AMP CTL

The standby mode of devices with 12V trigger input, can be switched on and off via AMP CTL, together with the Elector. This allows, for example, the SPL Performer s800, Performer m1000 or Performer s1200 power amplifiers to be ideally integrated into the set-up.

Sounds good

With all devices of the Professional Fidelity series SPL develop not only according to plan, but also by ear. Many components are installed on the circuit boards using Through-hole technology. This way engineers can ensure that they're can using the best sounding components.

VOLTAiR Technology

The 120V technology is SPL's reference technology. The 120V technology is unique. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In SPL Professional Fidelity series, its referred to as VOLTAiR technology.



The highest possible audio quality requires the highest possible audio operating voltage. The 120V technology works with +/-60 V. To be able to handle such a high voltage, SPL have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers.

This high voltage would destroy conventional components and operational amplifiers.

By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.

The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
