Pope Audio PRE-BX 500 Series Microphone Preamp/BAX EQ

500 Series microphone preamp module with API-style input transformer, Carnhill (Neve-style) output transformer, two GAR2520 Opamps, switchable 600/150 Ohm input impedence, and BAX EQ section


Product Description

The Pope Audio PRE-BX Mic Preamp is a versatile 500 series microphone preamp that packs a powerful punch and features a unique approach to EQ. For his first mic pre design, Pope Audio designer and founder Adam Pope found inspiration in the classic American console. The Pre-BX features a padless input stage topology, which utilizes a 2520 style opamp and 2622 input transformer. This transformer is switchable between 600R and 150R to help accommodate low impedance microphones.

The output stage of the Pre-BX goes in a slightly different direction. It features another 2520 style amp, but then uses a Carnhill quad transformer (as used on Neve products). This design choice will give smoother, less “in your face” sounds while still allowing for a subtle presence.

Pope Audio also includes a switch for lowering your output level by a ratio of 3:1. Simply flip the switch from 1:1 to 3:1 and you can drive the preamp circuitry for added saturation and color without overloading anything.

For the EQ section of the Pre-BX, Pope Audio is once again employing a Baxandall EQ. These simple controls feature a Hi and Lo band with very gentle slopes that start at 20KHz and 20Hz respectively. On the Pre-BX, the gains are about ±7 dB, so you can’t do too much wrong!

The Pre-BX features a combo switch on the front of the unit for easy patching with either XLR or Hi-Z. And with its robust and durable construction, the PRE-BX is built to withstand the rigors of professional use, ensuring that it will be a staple in your recording setup for years to come.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
