Enjoy the open and transparent sound of the SPL Channel One Mk3 in a compact, dual-channel preamp with the Pre One, a desktop unit with two discrete preamps. With a wide gain range of 8 to 62 dB and optional Hi-Z instrument input, you can draw out the full glory of nearly any input source, from condenser mics to passive instruments.
Each preamp features an independent 6 dB per octave high-pass filter for subsonic rumbles, switchable 48V phantom power, and a 180° polarity reversal switch. Each preamp features a selector, so you can choose Flair or Contour, analog EQ presets, and on the rear panel, you have a channel-selectable -20 dB input pad for overly hot signals. Each preamp features a balanced XLR 3-pin mic input and its own dedicated 1/4" TRS balanced output. Preamp 2 also includes a 1/4" TS instrument input (which automatically deactivates the mic input on preamp 2). This design allows the Pre One to process stereo signals if desired. Like all SPL products, the Pre One is manufactured in Germany.
Both preamplifiers have a 48V switch. This switch activates the required phantom power of 48 volts for the use of condenser and active dynamic microphones. The phase reverse function reverses the polarity of the signal. After pressing the switch, the phase is reversed by 180°.
