Shure AD8C Axient Digital PSM 8-Port Antenna Combiner
AD8C Overview
The Shure AD8C is an 8-port antenna combiner engineered for use with the Axient Digital PSM wireless in-ear monitor system, purpose-built to simplify RF infrastructure in complex multi-transmitter deployments. It consolidates the RF outputs from up to eight Axient Digital PSM transmitters into a single antenna output, reducing antenna clutter and streamlining system architecture at any venue. For installations requiring redundancy or improved coverage, the AD8C supports Spatial Diversity by combining up to four PSM transmitters across two transmit antenna outputs. System integrators, touring engineers, and broadcast facilities managing dense PSM deployments will find the AD8C essential to maintaining a clean, organized RF environment.
When paired with ADTQ or ADTD Axient Digital PSM transmitters, the AD8C enables signal gain compensation to help offset the inherent level loss introduced by combining, preserving system headroom and RF performance.
