powered using PA-KP local power supplies. Note, the use of one termination plug in each intercom channel. (One
termination plug is supplied with each US2002.) Only one termination plug should be installed per channel. Typically,
they are installed at the first intercom station in the chain. If 2 terminations are installed in a channel, the sound quality
and volume level will be noticeably reduced. IMPORTANT!: If a system power supply (SPS2001, PS2001L, etc.) is
ever connected anywhere in a channel, the termination plug should be removed from that channel, because the system
power supply already has a built-in termination. The advantage of locally powered stations is that they can be operated
over a greater distance than is possible when using a system power supply.
