The cost effective xIO 4×4 increases a system’s analog input and output channel capacity resulting in a reduction in overall price per channel. Designed exclusively for use with Dante-enabled Symetrix DSP units, each of the four analog inputs’ parameters (5 gain levels, phantom power) and four analog outputs’ parameters (mute), along with bus assignments, are configured using Symetrix Composer open architecture software. xIO 4×4 set up is logical and fast with no requirement to use third-party software; there are no mechanical switches or circuit board jumpers to set. Systems are simpler, cost less, and have fewer potential points of failure. A half-rack form factor conserves rack space. Optional 1U rack tray and 1/2U surface mount bracket are available for separate purchase.
