CAD Audio GXLIEM4 Quad-Mix Wireless In-Ear Monitor System with 4 Bodypacks

CAD Audio GXLIEM4: Quad-Mix Wireless Monitoring for the Whole Band

The CAD Audio GXLIEM4 is a quad-mix wireless in-ear monitor system on the license-free 900 MHz band, shipping with one transmitter and four bodypack receivers. It broadcasts four discrete mono mixes, giving up to four performers their own independent monitor feed from a single rack unit. The kit includes four sets of MEB1 earbuds, dual antennas, rack and antenna-relocation hardware and a power supply, so a full band can go in-ear in one purchase. For worship teams, gigging bands and multi-performer productions, the GXLIEM4 delivers personal monitoring at the scale a group actually needs.

Four Discrete Mixes from One Transmitter

A quad-mix system transmits four separate monitor feeds simultaneously, which is what a full band requires because every member wants a different balance. The drummer needs click and bass, the singer needs vocals, the keyboardist needs their own part, and the GXLIEM4 lets each dial in from the mixer independently. Consolidating four mixes into one transmitter keeps the RF footprint and rack space compact. Every player hears exactly what helps them perform, without compromise across the group.

1/4 in Inputs and 900 MHz Reliability

The GXLIEM4 accepts audio on 1/4 in inputs, connecting easily to aux sends and monitor outputs on virtually any mixer. It operates between 902 and 928 MHz, clear of the crowded TV spectrum, with 16 frequency-agile channels to sidestep local interference. This pairing of flexible inputs and a dependable band is what keeps four monitor feeds solid through a demanding set. The system is engineered to hold together when the stage is at its busiest.

ScanLink IR Setup and Battery Life

Setting up four wireless links manually would be tedious and error-prone, so ScanLink automates it: the transmitter scans all 16 channels, selects the cleanest, and syncs each bodypack over infrared. Each receiver runs 10 or more hours on two AA batteries with a high-contrast battery-life display, covering rehearsal and show on a single set. Range reaches up to 100 ft line-of-sight for large stages. Fast, repeatable setup and long runtime keep an entire band monitoring reliably.

Near-Infinite Expansion for Large Ensembles

The GXLIEM4 is built to scale beyond four performers. Because it works with the same GXLIEMBP bodypack receivers as the rest of the line, you can add near-infinite additional monitor positions to cover choirs, expanded lineups and rotating personnel. That headroom makes it a long-term platform rather than a fixed-size product, so a growing worship team or ensemble keeps one system as it adds people. The rack-mountable metal transmitter anchors a rig that expands with the group.

Who the GXLIEM4 Is For

The GXLIEM4 suits full bands, worship teams, choirs, theater and AV productions where four or more performers each need a personal monitor mix. It fits medium and large stages, houses of worship and multi-performer live shows, and its expandability serves ensembles that keep growing. Every musician gains independent control of their monitor feed, and the system scales without replacement. When a whole group needs to move to in-ears together, the GXLIEM4 is the platform built for it.
