When you need an Ultra Reliable Message On Hold player, we are pleased to offer our Fourth Generation Digital Message On Hold devices DMC and DMD. We have been making Message on Hold players for over 20 Years and during this complete time, we have been the major supplier of these devices in Australia. Our devices have proven to provide exceptional reliability and performance and we provide them with a Two Year Warranty.

All of our Message On Hold players :

  • Use a conventional SD Flash Card DMC or conventional USB Stick DMD (supplied with your unit), to store the MP3 based Message on Hold production that you will use.

  • Use a separate dedicated MP3 micro-processor which is designed to out Messages of the Highest Quality and can even use MP3 files created at the highest (320kbps) sampling rate possible (Broadcast quality). 

  • Use a High Power Amplifier designed specifically for Message On Hold applications.

  • Are extremely compact (a little larger than a packet of cigarettes) and weigh less than a standard iPhone. 

  • Use a convenient 3.5mm Audio Output (same as an iPhone)

  • Our cases have 2 Keyholes on the back allowing for Quick, Easy and Secure Wall Mounting. A plastic Wall Mount bracket is available at No Extra Charge on request.





DMC and DMD  can have up to 250 MP3 Files loaded on the Memory Card and they will play each of these files sequentially before returning to the first file once the last file has played. There is NO discernable gap between Messages. 

Messages start playing as soon as power is connected (9VDC or 9VAC) and will continue with Ultr Reliability until power is disconnected, or if Time Programmed to Stop Play (Models DMC6 and DMD6 only). Should there be an 'unintentional power disruption', they will restart play as soon as power is restored.
