OPERATION
The
IN3546R
is designed to switch up to 6 stereo audio signals. After hooking up all cables as described
in the Installation section, the unit will automatically switch to various input channels, mirroring the
channels selected on the attached
IN3500
/
IN3600
series RGB switcher. The
IN3546R
will power up
when the attached RGB video switcher is switched on. When an input is selected either manually or
automatically on the RGB switcher, the tally output will close the contact between the ground pin and the
appropriate channel select pin on the
IN3546R
CONTROL port, latching on the corresponding stereo
channel ( 1 - 6 ) as long as the voltage is applied.
The only controls on the
IN3546R
are the left and right audio attenuation pots for each input. These can
be adjusted to vary the output signal voltage for each input as necessary. Please note the
IN3546R
is a
passive switcher so these pots are for attenuation only. They work over a range from unity gain (voltage
out equals voltage in) at the extreme counter-clockwise position to 5% gain in the extreme clockwise
position with one complete rotation from stop to stop.
CAUTION:
When adjusting the attenuation pots, use only the small adjustment tool included
with the IN3546R or a small plastic TV alignment screwdriver, taking care not to apply too much
force to the control pots. If a large handled screwdriver is used the pots may receive too much
torque, resulting in damage to the controls. This type of damage is not covered by warranty.
