LINK's DigiFlex 1650/1651 Stereo Audio
Distribution Amplifier takes advantage of the latest
in Operational Amplifier technology. The front end
is high-impedance, balanced, with high common-
mode rejection. The output amplifier is capable of
driving low impedance (150Ω) loads and is
compensated for load capacitance of up to
10,000pF. Its wide bandwidth (>120KHz) will allow
for the distribution of SMPTE Time Code or BTSC
Baseband Stereo.
The LINK 1650/1651hasa unique signal presence
indicator on the rear panel. The rear panel module
with build-out resistors and fixed terminal blocks is
the model 1014. Plug-in terminal blocks are
available on the 1021 Rear Cell. The front panel
features a DC power supply monitor LED.
The LINK 1650/1651 is designed to reside in
LINK's DigiFlex 1000 frame. This rugged 2RU
frame can house up to 11 modules. An audio buss
runs the full length of the frame to allow monitoring
of any of the resident audio distribution amplifiers
by a single monitoring amplifier, model 1626. A
switch on the front of the module places the audio
signal on the frame buss. The versatile DigiFlex
1000 frame can also accommodate AES/EBU
Digital Audio distribution (using the DigiFlex 1652)
as well as Analog and Digital Video distribution.
Backed by LINK's 10-year warranty, the 1650/651
will provide years of outstanding performance.
Ultralow-noisecomponents(includingmetal-oxide
resistors) are used throughout the audio signal
path. Both the input buffer and output driver offer
noise figures of <7nV/Hz1/2. In addition, extreme
care has been taken in the printed circuit board
design to reduce noise and improve channel
isolation. The 1650 and 1651 are identical with one
exception: the 1651 has logarithmic bar graph
level meters for the left and right channel signal
indication.
