Audio Authority AVAtrix, 1156 and 1166 User Manual 1
b. Infrared commands returned from a Wallplate to Model 1176 can immediately select the source to be
played on that Wallplate.
c.
1176:
IR commands returned from a Wallplate to Model 1176 containing code intended for source
units or other equipment are repeated through the IR Output jack on the Model 1166. If a compatible
infrared control system is in place, and remote sensing of IR inputs from Wallplate locations is de-
sired, patch the IR Output jack to an input of the IR control system. Do not use IR connecting blocks
other than Model 1108 (see “Using Compatible Infrared Products” in Appendix A of this manual).
d.
1170:
All IR commands returned from a Wallplate to Model 1170 are repeated only through the IR
Output jack and perform no function within the switching system.
