Introduction
The NEAR
TM
6XL Power Amplifier delivers on what professional sound installers
require most: Power and Reliability.
Power
The 6XL provides 2 independent channels of amplification at 600W per channel
into 70V constant-voltage and 8-ohm speaker loads safely and securely. Located
on the rear of the amplifier are the Level Controls, High-Pass and Low-Pass Filter
Switches, and XLR/RCA inputs for each amplifier channel. The amplifier is
powerful (with total system power of 1200W with both channels driven), but also
compact — using up only 2 rack spaces (3-1/2") in a standard 19" rack.
Reliability and Functionality
Driven by a conservatively-rated toroidal power transformer, the amplifier is built
for solid performance with low distortion and a high slew rate. The amplifier
requires little maintenance and cleaning as internal electronic components are
located outside of the forced air stream flow. Front-mounted fan filters provide
easy removal and cleaning.
The 6XL amplifier has a variety of electronic protection circuits including overcur-
rent, DC voltage, and thermal circuits. A special Clip/Limiting circuit continuously
monitors the amount of distortion in the output signal and reduces input levels
as the amplifier approaches clipping. Back-Slope™ AC Voltage Stabilization,
Bogen‘s patented voltage stabilization circuitry, regulates the AC energy supplied
from the power toroid. This improves both system performance and reliability
despite varying AC supply conditions.
An energy-conserving sleep mode (defeatable) with instant-on return signal oper-
ation reduces wasted heat production in systems when not in use. In addition,
large output heat sinks and dual independently-controlled, high-output, variable
speed fans provide superior cooling and quiet operation while reducing dust
accumulation.
