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 in-store messaging and background music the Sonorous is available with message times up to 34-hours.
The Sonorous is also available with the optional Sonocrypt® 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. These key files are only supplied to dealers using this feature
