Rti 10-210860-18 Mixer Amplifier 4ch 125W 2ch 70V 250W

Product Description

The RTI 10-210860-18 is a multi-channel mixer amplifier designed for commercial and professional audio distribution applications. It delivers four channels at 125 watts each alongside two channels capable of operating at 70V or 100V at 250 watts combined, making it suitable for distributed audio systems in venues, facilities, and similar installations. Licensed audio-visual integrators and commercial AV technicians are the primary installers of this unit. The combination of low-impedance and constant-voltage output options in a single chassis provides installation flexibility across a range of system designs.

This mixer amplifier is suited for commercial audio distribution environments such as restaurants, retail spaces, houses of worship, schools, and office facilities. The 70V and 100V constant-voltage outputs support long cable runs to multiple distributed speakers without significant signal loss, a common requirement in large-footprint installations. The four-channel 125W section handles local or zone-specific low-impedance speaker loads. Installers working on background music, paging, or multi-zone audio systems will find this unit applicable to a range of commercial project types.

Installation Notes

Installation should be performed by a licensed AV integrator or qualified commercial audio technician. Power down the unit and de-energize the circuit before making any wiring connections to speaker outputs or signal inputs. Rack-mount installations should allow adequate ventilation clearance around the chassis to prevent thermal buildup during extended operation. Follow all applicable local electrical codes and manufacturer wiring guidelines when connecting constant-voltage speaker lines.
