The projector pole can be clamped to the back surface of
the clamping plate on the PMK 300, as shown in the
figure on the previous page.
Alternatively, the PMK 300 has a hole in the bottom
plate that allows the projector pole to be inserted through
the center of the plate. In this configuration, slide the
PMK 300 up from the bottom of the pole before the
projector is installed.

The provided U-bolt fits a pole with an external diameter
of 1.5" to 2.0". For larger or smaller diameter poles,
obtain a U-bolt from a local hardware store. The slotted

As additional amplifiers are added to the daisy chain,
the sensitivity of the volume potentiometer will change.
The maximum volume level (fully clockwise) will not
be affected. However the effectiveness of the minimum
volume level (fully counterclockwise) in reducing the
volume to inaudible levels decreases as more amplifiers
are added to the daisy chain.
N
When more than two MPAs are attached to the chain,
sound may begin to be heard even if the levels have been
set to their lowest. The muting of the output however
can be remedied with a contact closure button attached
between the Vol/Mute and Ground pin of the first MPA
in the chain.
