to any of the A/V outputs (connected to the
inputs).
AV8x1A with Audio Monitor Amp
This product operates the same as the AV4x1P
and AV8x1P with the exception of the headphone
jack output and the need for 12Vdc (used to
power the headphone audio amplifier). This
connector allows the user to monitor the audio by
the use of a standard 3.5mm plug stereo
headphone (not included), also a control knob is
installed on the front panel to allow the user to
adjust the volume level to the headphones. This
adjustment does not affect the volume of the
RCA audio outputs, it is just to allow a user to
monitor the audio passing through the AV8x1A.
Input Termination
The unselected video sources are terminated into
75 Ohm 1% loads. The unselected audio sources
are terminated into zero Ohm loads. This keeps
the audio crosstalk to a minimum. If termination is
not required, then the resistors may be clipped
from the printed circuit board. This will not
compromise the factory warranty.
Removing the Cover
AV4x1P: Remove the front panel by removing
both screws. Slide the top case off of the unit.
AV8x1P and AV8x1A: Remove one of the side
panels by removing all four screws. Slide the
bottom panel out of the enclosure.
