Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.
General Safety Precautions
Warning: Never install video equipment in a wet location or during a lightning storm.
Note: Install this equipment only in Restricted Access Areas (dedicated equipment rooms, equipment closets, etc.) in accordance with Articles 110-16, 100-17, and 110-18 of the
National Electric Code, ANSI/NFPA 70.
1 GENERAL
The ADC 16 x 1 Unity-Gain Combiner-Amplifier Panel (UGC Panel) is designed for use in 19– inch or 23–inch equipment racks (the mounting ears are reversible). Its function is to combine
16 sub-split signals into a single output signal. This panel is powered from facility 100 to 260
VAC 50/60 Hz through a standard modular power cord and uses active circuits to achieve 0 dB of insertion loss.
Figure 1 shows a typical application of the UGC Panel.
All signal connections to the UGC Panel are made through standard 75-ohm F– or BNC–type female RF coaxial connectors on the rear panel. There is also a front panel (20 dB down)
MONITOR connector for test equipment access to the UGC Panel's output signal.

2 PRODUCT DESCRIPTION
This section provides functional, physical, and technical descriptions of the 16 x 1 Unity-Gain
Combiner-Amplifier Panel.
2.1
Functional Description
Sixteen separate inputs can be applied to the input connectors of the Unity-Gain Combiner
Panel. Within the panel the input signals are applied to a summing circuit that combines them into a single output RF signal. The output of the summing circuit is amplified, then applied to a
20 dB directional coupler that taps off a portion of the output signal for monitoring purposes at the front panel monitor jack.
2.2
Physical Description
The UGC Panel is a putty white rack mount chassis measuring 19” W x 12” D x 1.75” H (48.26
x 30.48 x 4.45 cm).
A coaxial connector (F– or BNC–type, depending on model ordered) labeled 20 dB MONITOR is mounted on the front panel for signal monitoring purposes.
The UGC’s power input is located on the rear panel, as is the power switch. A green POWER
LED on the front panel indicates the status of the power supply.

3 INSTALLATION
Warning: Never install equipment in a wet location or during a lightning storm.
Use the following procedure to install the 16 x 1 Unity-Gain Combiner-Amplifier Panel on a
19–inch network rack, or equivalent.
Note: The mounting ears on the UGC panel can be reversed (with the longer sides extended) for mounting the panel in a 23–inch rack.

Figure 2. Installing 16 x 1 Unity-Gain Combiner-Amplifier Panel in Rack
1. At the designated rack location, align the mounting holes in the panel mounting ears with the threaded holes in the rack, then mount the panel on the rack with four #12-24 screws.
2. Connect AWG 18 (or larger) stranded wire to the FRM GND screw on the rear panel (see
3. Connect the designated cables to the F or BNC connectors (depending on model selected)
1 through 16 on the rear panel.
4. Using a modular power cord, connect the switch to a convenient source of AC input voltage, (for 100 to 120 volt operation see

Configuring the Unity Gain Combiner for 100 to 120 VAC operation
The Unity Gain Combiner is factory set for 240 VAC operation, with “230V” showing as the
voltage setting in the power inlet module window ( Figure 4 ). To configure the unit for 100 to
120 VAC operation, perform the following:
Note: The Unity Gain Combiner is supplied with a detachable power cord for 120 VAC operation. For 240 VAC operation, consult your local electrical code for the correct type or style of power cords required.

1. Make sure the power cord is removed from the power inlet module before continuing.
2. Pry open power inlet module door from the right side using a small screwdriver or equivalent.
3. Remove the fuse module using a small screwdriver or equivalent.
4. Rotate the fuse module 180º so that the text “115V” will show through the power inlet module window when the door is closed.
5. Place the fuse module back into the power inlet module, making sure that the fuse module is seated properly.
6. Close the power inlet module door, making sure that it snaps firmly into place, and that
“115V” does show through the window.
