What We Think

After wishes came true last year with the new API 512v, it seemed like only a matter of time before the classic 3124 met the same upgrade. Now with the just announced 3124v, you have the same set of 4 API preamps but with the flexibility of an output trim and 3:1 output transformer selection so you can really lean into it and dime in the perfect amount of saturation /color without clipping your converter. This would be an exciting tool for micing a drum kit, set of guitars, or any other source to give you a transient-filled push of unmistakable API punch.

Manufacturer's Description from API

Building on the enormous success of the highly revered 3124+, the 3124V is essentially the same unit, but provides two important additional features:

First, the 3124V offers front panel Variable Output Level Control, an extremely valuable addition given today’s professional workflow. “This is a feature long requested by the pro audio community, and we’re happy to provide it in the 3124V,” says API’s President Larry Droppa.

Second, the 3124V adds a switchable 3:1 output transformer selection, also on the front panel. "The 3:1 Output Transformer selection switch allows the user to alter how much gain comes from the different stages," explains API’s Director of Engineering Todd Humora. "Do you want more transformer gain, or do you want more 2520 gain, or both? You can choose exactly what you prefer, and then use the Variable Output to make sure the level is where you want it.”

All other design aspects of the 3124V remain identical to the 3124+, including the original circuitry, proprietary input and output transformers, 2520 op amps, the unique 5 year warranty and, of course, the unmistakable API sound. Units are now shipping.

Like the API 3124+, the 3124V is a high quality, compact, 4-channel mic preamp. It is equipped with the RE-115 K mic 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.
