Introduction

Thank you for purchasing our Magna Desktop 

or Rackmount Amplifier. 
These units are the first 100V line amplifiers 

with their own built in MP3 recorder and alert 

trigger. The PA Mixer Amplifiers are rated with 

power outputs from 30W, 60W to 120W, and 

are ideal for use in schools, supermarkets, 

banks, background music for public areas 

and general speech use. They are an all in 

one solution with multiple source inputs, a 

pre-amplifier and mixer power amplifier all 

contained in one compact unit. 
A USB port and SD card slot on the front 

of the unit provide easy access for MP3 file 

storage and playback. The micro USB socket 

on the back of the unit is to download your 

own 20 second alert message, which will 

automatically play back once triggered via 

the alert input contacts, for example: door 

contact, timer unit or push button.
The amplifier is designed with automatic 

overload protection, short circuit and high 

temperature shut off to avoid any damage to 

the internal circuits.
NOTE: The ‘Alert’ message is for alarm 

notification purposes only, it should not be 

used as an emergency evacuation notice. The 

recorded message will play immediately once 

the relevant contact has been triggered.
