Discrete 4-channel Mic/Line/Instrument Preamp with 65dB Gain Range, Variable Output, and Transformer Tap Selection
Like the API 3124+, the 3124V is a high quality, compact, 4-channel mic preamp. It is equipped with the AP2516 input transformer and the proprietary output transformer found in all API mic pres and throughout the API product line. Additionally, the 3124V offers Variable Output Level Control and switchable 3:1 output transformer selection. The unit has an internal 48-volt phantom power supply, which is switchable for each channel, as well as -20dB pad switches that affect both the mic and Hi-Z instrument inputs, both located on the front panel.
The 3124V also features up to 65dB of gain. Additionally, the Hi-Z front panel inputs feed directly to the op amps, which allow a low level input such as a guitar or bass to be amplified without a matching transformer or direct box. These Hi-Z inputs can take levels as high as +20dBu, making them perfect for keyboards and other high level devices. The mic preamp outputs are on rear panel male XLR connectors.

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.
Ideal for a variety of audio applications
API's commitment to quality means the 3124V provides a stellar front end to a wide variety of audio applications. The 3124V is designed with the professional engineer in mind, giving you four channels of premium preamp performance, while keeping the size and price at a reasonable level. Not only will it make your mics sound incredible, the unit's convenient front-panel hi-Z instrument inputs are engineered with the headroom to handle your active bass or hot outputs from keyboards and other gear. It's equally at home in commercial recording studios, mobile ENG or recording rigs, at front of house, or in your personal studio.
Premium API components inside
This preamp gives you the great sound and performance characteristics that make API gear so popular among studios, engineers, and musicians. The 3124V 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 found throughout the API product line. All four mic inputs of the 3124V are powered by a 48-volt phantom power supply — front panel switchable for each channel. Also provided are front-panel, per-channel polarity-reverse switches and 20dB pad switches that affect both Mic and hi-Z inputs.
Perfect for mics and instruments alike
You get plenty of headroom from this pre, whether you're plugging in a mic or an instrument. The 3124V can provide up to 65dB of gain, and with variable output you can optimize your gain staging. The front-panel hi-Z inputs routes directly to the op-amp, perfect for amplifying low-level inputs like guitar and bass without using a direct box or matching transformer. These inputs can take levels as high as +20dBu, making them ideal for active pickups, keyboards, and other high-level gear. The 3124V sports rear-panel XLR mic pre inputs and channel outputs.
