Many products have large transient surges at turn on and off which can cause damage to your speakers. By turning on your guitar amplifier 

LAST

 and making sure its Volume controls are set to minimum any transients from other equipment will not reach your loudspeakers. Wait 

until all system parts have stabilised; usually a couple of seconds.  Similarly when turning off your system always turn down the Volume 
controls on your guitar amplifier and then turn off its power before turning off other equipment.

Servicing:

 

The user should not attempt to service these products. Refer all servicing to qualified service personnel.

•   

Cables: 

 Never use shielded or microphone cable for any speaker connections as this will not be substantial enough to handle the 

amplifier load and could cause damage to your amplifier system.

•   

Caution:

 These professional loudspeaker systems are capable of generating very high sound pressure levels. Use care with placement 

and operation to avoid exposure to excessive levels that can cause permanent hearing damage. (Refer to guidelines on page 2)
