The Gräf & Meyer GONG MODULE 2.0 features a microprocessor-based audio player with multifunctional triggering and can optionally be equipped with a timer.

A total of 21 custom audio files can be played. The 16-in-4 matrix allows selection from 16 audio files triggered via 4 potential-free contacts. In addition, the GONG MODULE 2.0 has 4 prioritized “convenience contacts”, which play the corresponding audio file in a continuous loop as long as the respective input contact is closed. For testing purposes, audio signals are already stored on the included microSD card.

Operating states – Power, Play, Holiday Mode [MUTE – ON/OFF], and Error [monitored SD card] – are also displayed on the control panel.

The GONG MODULE 2.0 is highly flexible and can be positioned as a desktop unit or mounted using the included DIN rail clips.

Power is supplied via a USB-C port with a standard 5V DC ±10% power adapter (sold separately).

When used in conjunction with the compact ONE-500 PA and voice alarm system, the built-in USB interface can serve as the power supply.
