The dbx® 160A's unique "INFINITY +" inverse-compression mode actually decreases the audio output level below unity gain when the input exceeds threshold, a real lifesaver for correcting overbearing vocal choruses and controlling runaway house mix levels. A detector input can be used with an equalizer for de-essing sibilant vocals and selectively smoothing out boomy notes on acoustic guitar and bass. And two 160As can be stereo-coupled to process an entire mix or instruments mic'd in stereo, without shifting the left/right image. Its musical sound, easy operation and unequaled versatility made the original dbx® 160 a world standard. The 160A follows that tradition, while meeting the challenges of a digital world.ent in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 160A is for you.
