General Notes
 Amplifier connection:

 In order to avoid damage, it is advisable to establish and follow a pattern for turning on and off your 

equipment. With all system parts connected, turn on source equipment, tape decks, cd players, mixers, effects processors etc. 
BEFORE turning on your guitar amplifier.  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. 

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)

Servicing: 

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