power amplifier, audio ampl
The LM-2/3 is a cost effective power amplifier representing the state-of-the-art in professional quality performance. It is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability.
The LM-2/3 is a "Heavy Duty" models specially designed to work as hard into 2 ohm as most. With 3 TIERS power rails, Class H design, the amplifier work in extremely high efficiency because of less current consumption and heat dissipation
FEATURES
ØHigh-current toroidal transformers for greater 2 ohm power and low noise
ØSelectable input sensitivity in voltage 0.775V rms, 1.0V rms and 1.4V rms
ØSwitch for sub sonic filter 30Hz and below
ØSwitch for Earth link (on and off)
ØComprehensives Signal (SIG), CLIP (CLIP), Protect (PRO) and PAR/BRG (Parallel/Bridged) indicators to monitor amplifier working status.
ØAll signal inputs and outputs are on XLR male & female (2x XLR male & 2x XLR female)
ØBinding post and Speakon outputs
