Ashly KLR 2000 User manual

70V Rated* KLR uses Neutrik®

Components

5-Year Warranty

The KLR Series are lightweight, high-performance

ampliers incorporang the latest technologies delivering

quality and value at an aordable price. Whether your

applicaon is professional audio or xed performance

installaon, KLR ampliers are opmized to provide

reliable audio performance with sonic perfecon.

Covering a power range from 1000 to 2500 Was per

channel at 2 Ohms the KLR-2000, KLR-3200, KLR-4000

and KLR-5000 are perfectly suited for a wide range of

sound reinforcement. All four KLR ampliers are opmized

to deliver high levels of sustained power, extraordinary

audio performance, and road-proven reliability into 2, 4,

or 8 Ohm loads and are housed in a a uniform, rugged

2RU chassis. Each KLR amplier uses a switch mode

power supply which assures you of awless lows, punchy

mids and prisne highs. The output topology of the

KLR-2000 is Class-AB, while the KLR-3200, 4000, and

5000 are a 2-step Class-H design.
