High end 4 channel mic pre (amazing on drums) and the V version has the output trim so you can really drive the inputs without clipping your convertors. This item is in used, but very good condition, light used in my home studio, will have the smallest cosmetic scrapes on the top (whilst racking)

The API 3124V is a compact 4 channel mic preamp perfect for any professional engineer or studio. It has a RE-115K mic input transformer and a proprietary output transformer found in all API gear.

The 3124V offers variable output level control and switchable 3:1 output transformer selection. The unit has an internal +48v phantom power supply which is switchable for each channel along with a -20dB pad switch.

The unit provides up to 65dB of gain and the Hi-Z front panel goes directly into the op-amp, allowing any low level inputs such as a guitar or bass to be amplified without a matching transformer or D.I box.
