Features:

Flash Memory
A technological break through gives the 4400 the memory of the future.
The (Nand) flash memory assures the recording will never be lost due to loss of power.

Automatic Mixing
The 4400 automatically mixes messages with background music from a live feed.
Messages can be tape loaded.

Music Pass-Through
The 4400 allows a live music pass-through.

Variable Message Length
1-99 messages can be recorded at variable time lengths. The messages do not
have to be preset to a specific length

Internal Setting
The internal button on the unit allows for “on the fly” changes without having to
 power down the machine. No dip switch setting to mess with.
