Wunder Audio PEQ4R – 19″ Rack Mount Mic-Pre/EQ

The Wunder Audio PEQ4R is a 19″ rack-mounted mic-pre/equalizer that builds on the legendary PEQ2 with enhanced features for greater control and versatility. Designed in 2019 for Roger Waters’ 48-channel Wunderbar, the PEQ4R adds another mid-band for a total of four bands—low, low-mid, high-mid, and high—with selectable narrow or wide Q. This premium 4-band EQ and mic preamp delivers the thick, vintage-inspired Wunder Audio sound while incorporating cutting-edge features and superior craftsmanship.

• Global and Individual Band Bypass: Switch EQ totally out of the circuit or bypass individual bands for precise control.
• Discrete Active High-Pass Filter: Allows for effective low-frequency management.
• LED Metering: Includes green signal indicator and red clip light for real-time monitoring.
• Robust Design: Features a thick gauge mu-metal enclosure for RF protection, sturdy faceplate, and custom gun-metal gray knobs.
