Pre One
The Dual-Channel Microphone Preamplifier with discrete technology for outstanding sound.
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 a Hi-Z instrument input – so instruments like electric guitars, for example, can benefit from the sound of the Pre One.
In terms of technology and sound, the preamps have the same characteristics
as those in the SPL Channel One Mk3!
