Figure 7. Maximum Power Configuration for Channels 1 and 2. This power sup-
ply configuration should only be used at one point in channels 1 and 2. Typically, it
is set up at the central master station. This configuration permits about twice as
many remote stations on channels 1 and 2 than the configuration shown in Figure

. Note: A PS2000L may be substituted for the SPS2000A for headset-only opera-
tion.
