Each zone offers music level and source selection knobs, as well as level knobs for the two microphone inputs. Additionally, there are LF and HF controls for each zone, allowing for a customized sound for each zone. There are several options for remote source selection, volume control, and paging systems making the system a feature-packed single-box solution. The 46-120T ships with a power cord, a set of mating connectors for all real panel multi-pin screw-terminals, a set of four plastic feet, and a front panel security cover with mounting hardware.
