CHAPTER 2: NOW LET’S GET STARTED! CHAPTER 4: HOOKUP DIAGRAMS INTRODUCTION The WA12 MKII is our take on one of the most successful and iconic preamp types in the history of classic console designs. Our goal was to make this type of discrete transformer coupled mic preamp available for the first time at an affordable price, without compromising any of the design parameters and characteristics that make this type of preamp so desirable.
CHAPTER 4: HOOKUP DIAGRAMS CHAPTER 3: TECHNICAL SPECS HARDWARE CONTROLS - FRONT PANEL 1 WA12 MKII 2 3 4 5 1. HI-Z Input The front panel 1⁄4” input provides an active discrete DI circuit, which sends the instrument’s signal through the entire preamp circuit, including the input transformer, discrete opamp (operational amplifier) and output transformer. The thorough layout of the HI-Z’s signal path ensures that instruments are subject to the same robust preamplification as microphones.
CHAPTER 3: TECHNICAL SPECS 6 7 8 CHAPTER 3: TECHNICAL SPECS 9 10 6. Tone Switch This control switches the input transformer configuration from a 1:4 (step up) turns ratio to a steeper 1:8 (step up) turns ratio, drawing out a greater degree of coloration and impact from both the input transformer as well as the discrete op-amp. When engaged, the input impedance of the WA12 MKII is 150 ohms. When disengaged, the input impedance of the WA12 MKII is 600 ohms.
