How is the AC input voltage typically received in a line extender amplifier?

The AC input voltage is typically received in a line extender amplifier through the port seizure screw connection. This method allows for a secure and reliable means to connect the amplifier to the AC power source. The seizure screw connection is designed to establish a solid electrical contact, ensuring that the amplifier operates within its required voltage parameters.

Using this connection type minimizes disturbances and potential signal loss that could occur with other connection methods. It also aids in maintaining the integrity of the power supply, which is crucial for the amplifier’s performance. Other options do not provide the same level of reliability or security for transmitting AC voltage, emphasizing why the port seizure screw connection is the preferred choice in this context.
