Product Details
The switch-mode technology on LA amplifier replaces a large, heavy
AC transformer with a highly efficient and lighter-weight active
design. Special dual power supplys (one power supply for one
channel) make the bass stay full and powerful while the high end
remains crisp and clean.
Like other models from LEX, the** can also work as hard into 2 ohm
as most. The amplifier use Class H output circuitry, a form of
audio "turbocharging" that increases maximum power without
affecting the basic audio quality.
Features:
Ø High efficiency switching mode power supply design reduce the
amplifier weight
Ø Special dual power supply ensure more power to the bass
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)
