The Galaxy Audio DHXR4 (Code D 584 - 607 MHz) offers the same great features as the DHTRQUAD system, with 4 receivers in a single rack space chassis. The DHXR4 offers 4 independent receivers, each with Auto Scan, IR Sync, and 120 selectable channels. The receivers have also been improved with Tone-key squelch for improved rejection of outside interference. The DHXR4 has a built in antenna combiner and power distributor. The DHXR4 has 4 independent XLR outputs (one for each channel) as well as mixed output, allowing the user to submix the microphones on the DHXR4 and come out of one XLR or 1/4" output. The DHXR4 can be used with any 65 or 77 Series Handheld or Body Pack transmitter.
