5.4 Getting to Know Your 104L line Amplifier
The
104L
is a high performance line amplifier, which combines the functions of a distribution amplifier and line
driver. It accepts a single composite video input and provides four identical buffered outputs, which are
affected by gain and equalization controls located on the top panel. The gain and equalization controls are
designed to compensate for signal loss inherent in long cable runs. The gain control adjusts the overall signal
level, and the EQ. control boosts the upper frequencies most susceptible to loss. Bandwidth of 430MHz ensures
that the
104L
remains transparent even in the most critical applications. A 12V power supply is provided for
typical operation, but the optional 50P can power up to six Kramer devices requiring 12VDC. The
104L
is part
of the Kramer Tools family of compact, high quality, and cost effective solutions for a variety of applications.
Front panel features of the
104L
are described in Figure 4 and Table 4.
