The SPL Pre One Microphone Preamp is a dual-Channel Microphone Preamplifier with discrete technology for outstanding sound.
For SPL the sound is always in the foreground. When it sounds good, we like to listen. To get such a sound, you need experience and technical finesse. SPL has incorporated both into the SPL Pre One.
Discrete preamplifiers
Pre One is equipped with two preamplifiers. These have a discrete design and they are tuned for an open and transparent sound characteristic. In addition to the microphone input, the second preamplifier also features transparent sound characteristic. In addition to the microphone input, the second preamplifier also features a Hi-Z instrument input – so instruments like electric guitars, for example, can benefit from a Hi-Z instrument input – so instruments like electric guitars, for example, can benefit from the sound of the Pre One.
Power Supply
Good sound always starts with the power supply. This is where you lay the foundation for the performance of Good sound always starts with the power supply. This is where you lay the foundation for the performance of the entire device. Although we “only” supply a 12 V plug-in power supply unit, the secondary power supply inside generates a voltage level of +/-17 volts for the analog audio sections with which professional levels of up generates a voltage level of +/-17 volts for the analog audio sections with which professional levels of up to +22.5 dB can be achieved!
Number One in Sound
With the Series One – just as with all other SPL devices – we develop not only according to plan, but also by With the Series One – just as with all other SPL devices – we develop not only according to plan, but also by ear from the very beginning. Many important components are installed on the circuit boards using ear from the very beginning. 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.
