Always switch off and disconnect power cord when not in use

The Enhance control provides an increased definition at the low-end of the frequency spectrum giving you a tighter, punchier 
sound. The Enhance control does this by providing a dip in the frequency-response of the amplifier at approximately 150Hz.  
This dip reduces some of the harmonics of the important low-frequencies around 40-80 Hz producing better definition to 
your sound. Turning the control through to its maximum has the effect of boosting both the low and high-frequency content.

Controls the boost and cut of the low-frequency response of the pre-amplifier.  

The seven band graphic equalizer allows you to easily modify your tone and effectively ‘see’ the response you are getting.  
There are seven sliders covering a frequency range from 40Hz right through to 6KHz. When the slider is in the central position 
the signal at that frequency is unaffected or flat. Moving the slider up or down from the centre will Boost or Cut that 
frequency.

Controls the boost and cut of the high-frequency response of the pre-amplifier. 

Allows the on-board limiter to be defeated if desired. With the switch in the out position the limiter is engaged. The limiter is 
automatically triggered at high-output levels and is designed to prevent power-amp distortion at high-output levels. When the 
limiter is automatically triggered the LED lights up to indicate the limiter is active.  It is possible to have the limiter engaged but 
not have the LED active. The limiter monitors both power-amp clipping and speaker load so it automatically registers the 
cabinet-impedance and sets itself accordingly.

Sets the overall listening level of the amplifier.

XLR socket for direct-injection of the amplifier signal to a mixing-desk or additional power-amplifier. The XLR socket provides 
a balanced low-impedance output-signal from the pre-amplifier taken before any tone correction.

Indicates power is connected and the amplifier is switched on. 

AUX IN provided for connecting an external sound source such as; CD players, MP3 players etc.

Activates the on board high frequency horn
