The Pre73Mk4 British-Style microphone preamp brings the spirit of classic British consoles into your studio or live shows. Boasting a warm, punchy, and sweet sound, the Pre73MK4 is a true testament to the golden age of recording. Whether you want to get creative and add some color to your recordings, or you just want the clean signals you've come to expect from a high-end preamp, the Pre73Mk4 is the way to go.
Get vintage color and punch by cranking up the Gain knob without fear - a dedicated output control lets you attenuate the signal so you can drive the preamp without overloading your interface inputs. Engage the -14dB pad for even more control of hot signals, or keep things clean and transparent by backing off on the Gain and turning up the Output. Further sculpt your tone via the selectable low-pass filter to eliminate unwanted low-end rumble at the source, and use the selectable top-end Air EQ to add some shimmer and presence to your top-end. Use the Low-Z switch to toggle between 1200 or 300 resistance and hear how your mics react!
The Pre73MK4's switchable +48v mic input lets you use both condenser and dynamic microphones, while its 80 dB of Gain make it ideal for use with sensitive ribbon microphones, on delicate sound sources. Line-and instrument level inputs allow further connection to nearly any audio source, and you get an insert jack for using external processors like EQ's and compressors. You have your choice of TRS or XLR out.
True to classic preamps of yesterday, the PRE73MK4 was designed with a focused attention to component choices and build quality not found in other preamps near the same price. No surface-mount components or integrated circuits are used, and all inputs and outputs are transformer balanced, using two different purpose-optimized transformers. Its external power supply eliminates the risk of self-noise and its metal half-rack chassis is both sturdy and portable.

Great sound quality!
Instant upgrade over my UA Apollo unison preamps. Been using the UA Unison pres for years after I sold my Focusrite ISA One. I heard a difference with the ISA but I wanted save some space. Now I’ve decided to get an external preamp again and do not regret it. It’s so much smoother, cleaner and the 1...
