The API 2500 Stereo Bus Compressor will give your mix the glue and balance it's begging for. With tried-and-true discrete circuitry based around the 2520 op-amp, this highly flexible machine is a secret weapon for your final mix. Flip between feed-forward and feedback compression, switch between soft and hard knee with the touch of a button, and give your track a major helping of low-end impact with API's patented "THRUST" circuit. Dial through the range of variable linking to find the exact stereo width you're looking for, or keep both channels totally independent for dual-mono compression on one set of controls. Try running the left channel into the right channel and control the second stage of gain reduction with the output knob of the compressor -- an amazing way to lock down a vocal track during tracking.
