The Audio Box boasts an internal 10-hour 2,000 mAh LiPo battery and 1.4" LCD screen. To further improve power, the charger can both power and charge the unit at the same time. This means you can leave the Audio Box plugged into power while firing to ensure constant full power.

The LCD screen displays firmware version, battery life, signal, audio filename/position, and other valuable information.

The Audio Box is a stand-alone wireless audio output device for playing music in perfect sync with your 18R2 Controller and firing modules. Simply plug the Audio Box into your sound system and start your script on the 18R2 Controller.

In addition to providing audio synchronization, the Audio Box is fully wireless, with the same range as the COBRA firing modules (1,500+ ft. line-of-sight). This allows the shooter to be in the best position for firing the show, and the Audio Box to be in the best position for playing the audio. In addition, the Audio Box uses a lite digital signal to control the audio. Compared to beefy time code feeds that can be unreliable and require a constant transmission, the lite signal is very resilient to low signal environments as the Audio Box will continue operation even if signal is lost.

You can also use the Audio Box to add wireless COBRA firing modules to existing systems (i.e PyroDigital, FireOne, Pyromate, etc...) that accept a SMPTE, FSK, or other time code feed.  Simply plug the output of the Audio Box to the 3rd party firing system, start your 18R2 Controller, and the COBRA firing modules fire together with the firing modules of the 3rd party firing system controlled by the Audio Box output time code signal.

You can control multiple Audio Boxes using a single 18R2 Controller. Each Audio Box can play the same, or different MP3 audio files allowing for a lot of flexibility and creativity with your audio design.
