Blast Box Operation: 

 

To pair Bluetooth begin by pressing and holding the 

Master Volume

 knob for 1 second to turn on the 

amplifier. You will hear a 4-tone turn on noise followed be a single beep, in addition the LED light will 
blink rapidly. Turn on the Bluetooth on the device you wish to pair (cell phone, media player, tablet, 
computer, etc...) and select "M200 BT4.2". The Blast Box will beep twice and the LED will slowly blink 
confirming the connection. 
 
Tips for operation: 
• For best results set the 

Master Volume

 to the 3 o'clock position (pointing to the right) and use your 

audio device to control the volume. 
• For flattest response position the 4 control knobs (

Sub Level

Sub Filter

Mid/High Level

, and 

Treble

to the 12 o'clock position. 
• The polar response is angled upwards about 15

°, 

so feel free to set the Blast Box on the ground, no need 

to worry about listening on axis. 
• For best bass response, and highest output, position the Blast Box near a wall or other rigid surface. 
• Lower the 

Sub Level

 and increase the 

Mid/High Level

 for maximum output capability.
