The RUMX4L is the ideal choice in many applications where a combination of balanced and/or unbalanced linelevel signals needs to be mixed. Balanced connections use XLR connectors. Unbalanced signals are coupled through phono jacks. Each of the four RUMX4L inputs can accept either a balanced XLR linelevel input or an unbalanced linelevel phono jack input. The unbalanced phono jack LINE OUTPUT from one RUMX4L may connect to the unbalanced input of other equipment, or may be connected to the DIRECT input of another RUMX4L or an RUMX4 to expand mixing capabilities. Up to 3 RUMX4 type mixers may be rack mounted in a single rack unit using an RDL RURA3HD rack adapter. The RUMX4L provides one balanced output, switchable for mic or line level. Audio levels are adjustable on the front panel. Each input channel is equipped with a frontpanel dualLED VU meter that follows standard VU ballistics. The final mix is displayed on an LED string VU meter featuring a visually comfortable arc motion. A factory installed output isolation transformer is available by ordering the RUMX4LT.
