This is a wireless version of model ASL4-ND3. It contains an integrated Bluetooth receiver capable of receiving data from a Limitimer equipped with an integrated or external Bluetooth transceiver over distances of 300 feet.  When used hardwired, the audience signal light may be powered directly from Limitimer or plugged into an AC outlet for distances of more than 50 feet. They may be set to receive any or all Limitimer programs. This signal light allows connections via Cat-5 or XLR cable and contains input-output ports so that additional signal lights may be daisy chained. The audience signal light has multiple in-out jacks for a variety of interconnections.

This audience signal light can optionally display time of day as either 12- or 24-hour when the connected Limitimer is turned off. Digits can be set to stop counting at 0:00 or continue counting to display overtime.

A flip-out kick stand makes for convenient setups as a downstage monitor. On the back of the display, there are accommodations for 100mm Vesa Mounts.
