Overview
  • 1Description

The System 84 Model B from RDL is a rack-mountable eight-in, four-out mono matrix router and audio mixer with very low self-noise. The inputs can be mixed to the outputs in any combination. The functions of the System 84 Model B are controlled by 32 logic lines on a single input connector. Functions may be selected using dry contacts, or the unit can be software-controlled using a computer with a logic-control in/out card.

All I/Os are connected via plug-in terminal blocks. Levels can be precisely adjusted using rear-panel trimmers. With all of those features, plus solid-state switching, studio-quality mixing, and excellent headroom in a 1U rack-space housing, the System 84 Model B is a great addition to any sound system.
