ELVIS 15.2XLA wooden cabinet is designed for professional stage performance. This series use high density
particle board 18mm material for the body of the cabinet. With the accuracy crossover point makes the sound
more clear. It adopt spherical horn in polypropilene reinforced shows excellent tweeter performance. and has
wide directional angle 80 H 80 V (1KHZ-16KHZ), with the Power ModII inside. The woofer power is 350 Watt
EIAJ at 4 ohm, the tweeter power 65 Watt EIAJ at 4 ohm
All these characters made them very suitable for any place.

FUNCTIONS:

1.Gain Control: This control adjusts the input gain by a range of -20 dB to +20dB.

2.Clip LED:This LED lights up when the input signal is too strong. It warns that the output signal may cause
distortion. Please attenuate the level of the input signal.

3.Power LED: This LED lights up when the unit is powered on.

4.AC Inlet: This jack is used to connect the AC power (100-120V AND 220-240V) supply with the supplied Power
Mod II.

5.Output Connector: Low sound(Section A) output and high sound(Section B) output of amplifier with Power
Mod II which is used to connect devices such as the effects returns power Speaker inputs.

6.Input Connector: This is a XLR balanced jack with preamplifier.
