A statement!
Up to 70dB of gain in an all-tube preamp is a statement and shows API's long experience in building outstanding audio gear. If you're looking for classic tube sound paired with phenomenal preamp gain and a great signal-to-noise ratio, you can't go past the API Select T12.
All features at a glance
The API Select T12 is a high-end all-tube preamp with two channels. It can be used for microphone signals as well as for direct connection of instruments via the Hi-Z connector. For the inputs, a 180° phase rotation, 48V phantom power and a -20dB pad are switchable. There is also a three-stage low-cut (60,120 & 240Hz) available and variable input impedance. Like all pots, the preamp gain and output trim control(level) are detented, so settings from previous sessions can be quickly restored.
Meter Control
Two high-quality VU meters display the output level per channel. A red LED lamp indicates when the peak of +18dBu is exceeded. This way you get an additional warning from the unit in case of overloads.
