INSTALLATION
The IN3546R rear panel connections are shown in the diagram above.
1. Connect the audio signals from each source to the INPUT connectors (labeled 1 - 6)
as required.
2. Connect the IN3546R OUTPUT to the input of the next device in the audio system (mixer or
amplifier).
3. Finally, connect the IN9112 or IN9133 15 pin control cable between the control port on the
IN3546R and the IN3500 / IN3600 Series RGB switcher contact closure port. This provides
power to the IN3546R and a control link, triggered by the RGB switcher's tally outputs. The
IN3546R will power up along with the IN3500 /IN3600 series switcher to which it is linked.
Consult the IN3500 / IN3600 Series manuals for more information about their tally output functions.
USING THE IN3546R IN STAND-ALONE CONFIGURATION
Some applications may require the IN3546R to be used as a stand-alone stereo audio switcher. Since the
IN3546R normally receives power and switching commands from the attached RGB switcher, the
following procedure must be followed in order to use the IN3546R in a stand-alone configuration.
1. The IN3546R must be special ordered for stand alone operation. INLINE will make
factory modifications to allow for stand alone operation, which includes the addition of
jumper J8. When J8 is closed the unit is set for 9V or 12V power input on pin 8. The unit
cannot be used in conjunction with an IN3500 / IN3600 Series switcher when J8 is closed or
damage may occur.
2. Power - The installer must construct a special power/control cable according to the pin out
information on page 5. The installer must also provide a 9 volt 300 mA (min.) power source
to power the unit. The power from the 9V supply is applied to pin #8 on the IN3546R control
port. The unit contains an internal 9V to 5V power transformer. Do not apply any voltage
to pin #9.
Switching - In order to select different channels, a control device must be wired to provide
latching contact closure between the ground pin (#7) and the appropriate channel selection
pins. Example: In order to select input #2, provide a latching contact closure between pin
#14 and pin #7.
