API 3124V 4-Channel Microphone/Line Preamp

Discrete 4-channel mic/line preamp
MFR# 3124V

Product Description

Since the 1960s, API has provided high quality, discrete, studio grade pre-amps. Their punchy sound is highly preferred by audio professionals on drums, rock guitars, bass, vocals, or anything that needs a little attitude. There are over 700 API consoles in leading recording studios and broadcast facilities around the world, now with the API 3124V you can get that same pro sound, without buying the entire console.

The 3124V has four discrete microphone pre-amps, the same preamplifier found in all API consoles. The microphone preamp can give you up to 65 dB of gain, where the Hi-Z input patches directly to the Op-Amp, allowing line level signals such as an electric guitar, bass, or keyboards to be plugged directly in without the use of a direct box.

On the front panel, each channel is equipped with a VU meter, gain control, phase polarity button, 48 V Phantom Power button, 20 dB pad that works on the mic and line inputs, mic/line selector, and the Hi-Z 1/4" input. The rear panel has XLR inputs and outputs for each channel. The 3124V also features Variable Output Control and switchable 3:1 output transformer selection.

There’s a reason it’s an industry standard. It’s fast, full, and can sound great anywhere from clean to pushed. It’s that 10% extra that makes or breaks the perceived quality and it gives you that in spades.

Kick in, kick out, snare top and snare bottom. Sounds great.

Dealing with Vintage King was painless. Unit arrived within a few days of ordering it. (No "supply chain" issues...)
The unit itself does what it's supposed to. Using it on live drums. Kick/snare/2 overheads. Very happy with results.

It’s legendary, loving it on drums and guitars. One of those pieces of gear that make you smile as soon as you hear it.

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.
Phil T.
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.

Thanks for your great service and getting this out today. You guys really are the Kings!
