OUR PART # WA12/500
Warm Audio's WA12 uses custom-designed Cinemag input and output transformers. This preamp is fully discrete, using 48V of phantom power, 2 Meg Ohm True HI-Z inputs (front panel), and a high-voltage 17131 style operational amplifier to send instrument signals through the entire circuit. That makes it great for guitars, bass, keyboards, and others that have a ¼” output jack. The WA12 also has a TONE button that switches the input impedance from 600 ohms to 150 ohms, which changes the tone of both the mic and HI-Z inputs.
