Configuring the IMR-4
8) The IMR-4 has a bank of 6 DIP Switches. Access the switches by
pulling back the clear adhesive tab over the rectangular access hole.
Use a small screwdriver or pen tip to slide the switches on or off. Be
sure to replace the tab after setting the switches. Settings are as
follows:
a. Switch 1 enables the AUX-1 input. Set this switch in the OFF
(Down) position if you do not intend to connect any device to
the AUX 1 input.
b. Switch 2 enables the AUX-2 input. Set this switch in the OFF
(Down) position if you do not intend to connect any device to
the AUX 2 input.
c. Switch 3 and 4 select the input sensitivity for the AUX-1 input.
Set these switches in the OFF (Down) position if you are
connecting a line level output device (line output from TV or
MP3). Set these switches ON (Up) if connecting from a
loudspeaker output (headphone jack or receiver speaker
output).
d. Switch 5 and 6 select the input sensitivity for the AUX-2 input.
Set these switches in the OFF (Down) position if you are
connecting a line level output device (line output from TV or
MP3). Set these switches ON (Up) if connecting from a
loudspeaker output (headphone jack or receiver speaker
output).
