Message On Hold Player Sonorous™ v2.0
Digital Announcer

Sonorous v2.0 message on hold player from Nel-Tech LabsThe Sonorous™ v2.0 is a state-of-the-art digital audio recording and playback device designed to provide a continuous-play audio source for message-on-hold, background music or any other audio application where high-quality audio playback is required. The audio program is loaded from a standard MP3 burned CD using a pure digital-to-digital transfer into a high-density flash memory file system. After audio is loaded the CD can be removed and the audio is played from its 8Ω and 1KΩ output jacks on the rear of the unit.

The Sonorous has a base memory of 64 minutes which can be used for message-on-hold or shorter message applications. For longer message applications such as instore messaging and background music the Sonorous is available with message times up to 51 hours.

The Sonorous is also available with the optional Sonocrypt™ Level 3 encryption key technology. This technology enables you to protect your units from being loaded with any end-user MP3 file. When a CD is burned for your customer an additional key file must be placed on the CD to make it work. This technology enables dealers to protect customers units against unauthorized loading of MP3 files.
