The Overload LED will turn on if the signal level within the signal path exceeds the linear operating range. In order to ensure the correct operation of the amplifier without signal distortions reduce the gain setting until the Overload LED turns off. The Overload LED may also turn on under the following operating conditions: - The amplifier is operated with open input or with a high source impedance. For proper operation please use a source impedance of less than 100 M or switch to a lower gain setting. - When using a DLPVA-F-D with differential input stage the Overload LED may turn on if the common mode input voltage exceeds 5 V or if the source is totally floating with respect to the amplifier ground. For proper operation make sure that the common mode voltage stays within 5 V with respect to the amplifier ground and make a valid connection between the source ground and the amplifier ground to ensure that the inputs cannot drift outside the tolerable common mode range.

For remote control a switch setting, set the corresponding local switch to "0 dB", "AC" and "1 kHz" and select the wanted setting via a bit-code at the corresponding digital inputs. Mixed operation, e.g. local gain setting and remote controlled bandwidth setting, is also possible.
