The DHTRQUAD offers the same great features as the DHT system, with 4 receivers in a single rack space chassis. The DHTRQUAD offers 4 independent receivers, each with auto scan, IR sync and 120 selectable channels. The DHTRQUAD has a built in antenna combiner and power distributor. The DHTRQUAD has 4 independent XLR outputs (one for each channel) as well as mixed output, allows the user to submix the microphones on the DHTRQUAD and come out of one XLR or 1/4" output. The DHTRQUAD can be used with any 64 or 76 series handheld or body pack transmitter, in addition to our wireless shock mount base, the SM-W76.
