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 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.Preamp & Direct OutOn the output side, power amplifiers or active loudspeakers can be connected to the preamp output sockets using XLRs. The Direct Out via RCA picks up the output signal before the volume control and thus offers the possibility to connect a headphone amplifier.Everything under control – AMP CTLThe 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 goodWith all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.The VOLTAiR TechnologyThe 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology 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, we 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.
