Product Description
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
Ø High-current toroidal transformers for greater 2 ohm power and low noise
Ø Selectable input sensitivity in voltage 0.775V RMS, 1.0V RMS and 1.4V RMS
Ø Switch for sub sonic filter 30Hz and below
Ø Switch for Earth link (on and off)
Ø Comprehensives Signal (SIG), CLIP (CLIP), Protect (PRO) and PAR/BRG (Parallel/Bridged) indicators to monitor amplifier working status.
Ø All signal inputs and outputs are on XLR male & female (2x XLR male & 2x XLR female)
Ø Binding post and Speakon outputs
