API 3124V Discrete 4-Channel Mic/Line Pre

Product Description
$3,130.25
Maximum quantity available reached.

API: 3124V Mic Pre

Features

  • Classic API Circuit Design
  • Uses API 2520 Op Amps
  • Variable Output Level Control
  • 3:1 Output Transformer Tap Selection
  • Four female XLR mic inputs
  • Four front panel 1/4" Hi Z instrument inputs
  • Front panel polarity switches
  • Front panel -20dB pad switches
  • Front panel mic/instrument switches
  • Front panel 48V power switches

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.
