the aux button for the Dolby Digital input.
1. Set the SRA5 CP selector switch to the “55” position.
2. Set the SRA5 Mode switch located behind the front access panel to “Remote.”
3. Use a shielded pair such as Belden #8451 for the audio and an 18-24 gauge single
conductor wire for the control line. Connect the shields at the SRA5 end only.
