Product Overview

The Williams AV CHG 520 is a 5-bay drop-in charger for IR RX20 under-the-chin infrared assistive listening receivers. The 6-hour smart charger docks, charges, and stores up to five receivers at once, keeping an infrared assistive listening system organized and ready between performances or services. Up to three CHG 520 chargers can daisy-chain from a single power supply, so capacity grows with the receiver count without adding outlets.

Product Description

The drop-in bay design eliminates battery swapping: staff seat each IR RX20 directly into a bay and the charger replenishes the receiver’s internal rechargeable LiPo battery (BAT 020) over a 6-hour smart charge cycle. Individual red LED indicators at each bay confirm that every receiver is seated correctly and charging, which makes end-of-night checks at an usher station or box office quick and reliable.

Daisy-chain capability is the CHG 520’s practical advantage for growing systems connect up to three chargers (15 receivers) to one power supply, reducing cable clutter and outlet requirements at the charging station. The black metal and plastic housing is built for daily handling in theaters, courtrooms, and worship spaces where receivers circulate constantly. As a storage point, the charger also helps staff verify that all checked-out receivers have been returned.

For larger inventories, the CHG 1520 15-bay charger pack bundles three pre-configured CHG 520 units with jumper cables. Find IR transmitters, emitters, and receivers in the Williams AV collection at Creation Networks.
