The PS 4/5LA EVO Plastic Speaker Cabinet is designed for professional stage performance. It adopts Italian

design style on the handle. PS 4AL EVO contains a woofer (12” 4ȍ110-220W) and tweeter (15W 8ȍ), while

the PS 5LA EVO has built-in woofer (15” 4ȍ150-300W) and the tweeter (15-30W 8ȍ). This plastic cabinet

features clear tone and thick bass to reproduce clean timbre. (PS 4LA EVO & PS 5LA EVO LOW Output

Power200Watt Class AB / HIGH Output Power 50Watt Class AB), which guarantees its availability in any

applications.

Function & Features of speaker module

PS 4LA / 5LA EVO speaker module is designed for matching the PS series plastic speaker cabinet. The

built-in precision electronic crossover separates the HF signal and the LF signal within PRE-AMP before

discrete power amplification so as to exactly reproduce the original sound. The rated power output of bass

power amplifier is RMS 200W at 4ȍand that of the treble power amplifier is RMS 50W at 8ȍ. If increase the

output power based on unchanged cost of PS 4LA & PS 5LA, the main features are as follows:

1 input volume control knob

1 groupof Input Combo jack

1 group of balanced chain output

Clipping LEDindicator present input signal strength

Overload andoverheat protection
