Principles of Operation 4-2
Overview Continued
The devices connected to the load are referred to as "high-side NPN and PNP"
and the devices connected to ground are referred to as "low-side NPN and PNP .
Positive current is delivered to the load by increasing conductance simultaneously
in the high-side NPN and low-side PNP stage, while decreasing conductance of
the high-side PNP and low-side NPN in synchrony.
The two channels may be used together to double the voltage (Bridge-Mono) or
the current (Parallel-Mono) presented to the load. This feature gives the user
flexibility in maximizing the power available to the load.
Our thermal diffusers (heat sinks) are fabricated from custom, convoluted fin
stock that provides an extremely high ratio of area to weight. All power devices
are mounted directly to massive heat spreaders that are electrically alive.
Electrifying the heat spreaders improves thermal performance by eliminating the
insulating interface underneath the power devices.
4.2 Features
AE T
ECHRON
LVC 608/623/2016 amplifiers utilize numerous innovations
including grounded bridge and ODEP technologies. Cooling techniques make use
of the what is essentially air conditioner technology. Air flows bottom to top, and
front to side. Air flows a short distance across a wide heat sink. Output transistors
are of the metal can type rather than plastic case. This allows for a significantly
higher thermal margin for the given voltage and current ratings. All devices used
are tested and graded to ensure maximum reliability. Another electronic technique
used is negative feedback. Almost all power amplifiers utilize negative feedback
to control gain and provide stability, but
AE T
ECHRON
uses multiple nested feed-
back loops for maximum stability and greatly improved damping.
Features specific to the AE T
ECHRON
LVC 608/623/2016 Series include three
separate power transformers (one for each channel and one for low voltage), a full
time full speed fan, slew rate limiting, and protection circuit for muting delay or
protective action. This amplifier can operate in either a Bridged or Parallel Mono
Mode as well as Dual Mode. A sensitivity switch allows selection of input voltage
required for rated output. Level controls are mounted on the front panel and are of
the rotary type.
