3.1 Defining the 104LN 1:4 Differential Video Line Amplifier This section defines the 104LN.
Figure 2 illustrates the INPUT GROUND switch: Figure 2: 104LN 1:4 Differential Video Line Amplifier (Underside) By default, the INPUT GROUND switch is set to FLOAT (the input signal is isolated from the chassis). If the image appears noisy, set the switch to ON (the input signal is grounded to the chassis).
4 Connecting the 104LN i Always switch off the power to each device before connecting it to your 104LN. After connecting your 104LN, connect its power and then switch on the power to each device.
