DESCRIPTION
The IN2055 and IN2056 are high performance video amplifiers with gain and peaking controls. The
IN2055 is a 1 in 4 out distribution amplifier, and the IN2056 is a 1 in 1 out line driver. These units
feature a very compact design which allows them to be installed in a very small space and offer 200
MHz bandwidth performance. The gain and peaking controls can be adjusted to compensate for signal
loss due to long cable runs, and may be used to drive a signal as far as 1000 ft. Multiple IN2055 units
can be looped together to provide additional outputs.
COMPATIBILITY
The IN2055 / IN2056 offer extremely wide bandpass characteristics and are compatible with hi-
resolution monochrome signals, as well as with low resolution color composite video signals such as
NTSC, PAL, or SECAM.
INSTALLATION
1. Connect the video signal from the source to the IN2055 / IN2056 input.
2. Connect the output(s) to the display device(s) or other equipment.
3. Apply power to the unit (9 V 200 mA DC) using the supplied IN9202 power adapter.
4. Adjust gain and peaking controls as needed (see Internal Controls section for details.)
OPERATION
The IN2055 and IN2056 are designed to distribute/extend video signals. These units have individual
gain and peaking controls for each output which can compensate for cable losses, and can extend a video
signal as far as 1000 ft without any degradation of the signal. Actual drive distance depends on the
resolution of the signal, and the cable used. Typically, low resolution video signals (15 KHz-30 KHz)
can be sent 600-800 ft, and high resolution signals (30 KHz and above) can be sent 200-400 ft.
The gain controls can be used to compensate for video signal voltage losses. Peaking may be used to re-
boost high frequency components which have been attenuated by long cable runs. The peaking control
employs an equalization circuit, introducing an adjustable high frequency peak centered at 100 MHz.
Please note that this high frequency equalization is optimized for high frequency signals and will have
very little effect on lower frequency signals such as composite NTSC.
