Overview
3 Overview
The Kramer 123Vxl Differential Video Line Amplifier is a highperformance line amplifier for composite or SDI video signals. It splits an
input source to 3 identical outputs and includes controls and circuitry to
compensate for signal losses and noise inherent in long cable runs.
In particular, the 123Vxl features:
Special differential amplifying circuitry that eliminates common
mode noise and hum problems commonly found in long video
lines, almost completely isolating the input from the outputs
High bandwidth of 425MHz (-3dB)
Gain and equalization trimmer controls to compensate for signal
losses inherent in long cable runs
A Kramer TOOLS enclosure and 12V DC supply voltage
To achieve the best performance:
Use only good quality connection cables1 to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
123Vxl away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
