Have you set up the 271 to have a source input to utilize the Digital DB25 input ( Altitude 32 ) or the Analog DB25 input ( Altitude 16 )?

If a Altitude 32, have you set a source and preset to output on the AES 16 digital outputs?

Have you set the speakers to use the RJ45 connection?

Have you set the 271 comms to master 1/2 or master 3/4?

Put the IR remote in the drawer and forget it exists.

Both the Trinnov and the 271 are controllable via phone apps or better yet, use a control system.

All changes on the Trinnov need to be saved in your preset.
Be sure to store changes to the 271.

In my system 271 and Altitude 32, I use the trigger out from the 271 to the trigger in on the Trinnov. I have found this to be the most reliable way to control things. I initialize the DSP volume to 87 upon system startup. Volume is controlled by the Trinnov. In my system in the 271 settings, the controller is set to Auto, as are the speakers.

Trinnov, Ayre Acoustics and Meridian use some of the same IR codes. If any of these are used in the same system, a proper control system is a must.

Let us know how you get on.
