Premium API parts inside
This preamplifier offers the amazing sound and performance characteristics that make API gear so popular among studios, engineers, and musicians. How? The model 3124+ utilizes the same microphone preamplifier circuit that is used in all API mixers. It uses the RE-115 K microphone in transformer and the same Out transformer that is used in all API equalizers. All four microphone inputs of the 3124+ are powered by an internal 48 volt phantom power supply, front panel selectable for each channel. Also provided is a front panel 20dB pad switch that effects both the Microphone and Line in.

Perfect for microphones and instruments alike
You get plenty of headroom from this pre, whether you're plugging in a microphone or an instrument. The model 3124+ can provide up to 65dB of gain to an Out clip level of +30 dBm. The hi-Z front panel In goes straight 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 Out is an XLR connector.
