API 3124+

Discrete four-channel mic/line preamp with DI
MFR# 3124+

Product Description

Both the API 3124+ and the 3124M+ are designed with the professional engineer in mind, giving the highest possible quality four-channel mic preamp and with the 3124M+, an audio mixer, while keeping the size and price at a reasonable level.  Several 3124M+ mixers can be linked to increase the number of bussed channels.  Both models are equally at home in the control room, the studio, and news or recording truck, at the house console, on the stage, direct-to-DAT or at the artist's disposal for the source of his music.

The model 3124+ utilizes the same microphone preamp circuit that is used in all API consoles.  It uses the RE-115 K mic input transformer and the same output transformer that is used in all API equalizers.  All four mic inputs of the 3124+ and the 3124M+ are powered by an internal 48 volt phantom power supply, front panel switchable for each channel.  Also provided is a front panel 20 dB pad switch that effects both the mic and line in.

The model 3124+ can provide up to 65 dB of gain to an output clip level of +30 dBm.  The Hi-Z front panel input goes directly to the op-amp, allowing a low level input such as a guitar or bass to be amplified without a matching transformer or direct box.  This Hi-Z input can take input levels as high as +22, making it perfect for keyboards and other high level devices.  The rear output is an XLR connector.

The model 3124M+ is a 3124+ with the addition of a complete stereo mixer.  In conjunction with the gain control of the 3124+, the 3124M+ adds a stereo panner with a level control, and a post "fader" aux send.  The stereo panners and the aux sends are bussed to master output controls and then to the rear panel jacks.  A stereo AUX return is provided to return effects or cascade additional mixers for more inputs.  The unique aux return pot acts like a panner to balance the left/right signal, yet staying stereo.  It can also be used as a mono return.  A standard 3124+ can be further expanded to an "m" at the factory.  Several options for the "M" include a discrete unbalanced stereo output or a discrete balanced stereo output.

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.
