The 500 Series WA12-500 MKII Dual-Transformer Microphone Preamplifier from Warm Audio is designed for high gain (+71 dB), high headroom, and low noise. It is suitable for all types of recording applications. It is based around a discrete op-amp, the X731, considered to be the predecessor to the modern 2520-style op-amp. The X731 can achieve vibrant, clean, and lifelike tones; but can also be driven into mild saturation at much higher gain levels. The WA12-500 MKII can also accept any discrete op-amp, which conforms to the ±16V, 2520 pin out standard.
- Utilizes premium grade input and output USA CineMag transformers
- Can be replaced with other 6-pin 2520 foot-print op-amps for varying tone/flavor
- TONE button - Switches the input impedance from 600 Ohms to 150 Ohms, changes the tone of both the microphone and HI-Z inputs
- 2-MOhm true HI-Z input on front panel, sends instrument signal through entire circuit including both Cinemag transformers and the discrete op-amp
- Suitable for guitars, bass, keyboards, and other instruments that have a 1/4" output jack
- Output attenuation control (after the CineMag output transformer) allows for driving the preamp and transformers into saturation
- LED meter gain indication
