If tunings are not showing correctly on channel 1 of a Crown CDi Drive Core amplifier, here are some focused troubleshooting steps and possible causes to investigate:

Check Output Configuration

• Go into Hi Qnet Audio Architect (or System Architect, depending on your setup).  
• Open the amplifier's configuration.  
• Verify that channel 1 is assigned and active. Sometimes, tunings may not appear if:

The channel is not routed properly.  

It's part of a custom configuration (e.g., bridged, linked, or unused).  

Preset Issue

• Ensure you're loading the correct preset.   
• Tunings are preset-specific.   

Presets can be corrupted or overwritten.  Try loading a known-good preset and see if tunings appear correctly. ​ 

Firmware Check

• Confirm the amp is running the latest firmware. Outdated firmware can cause UI and tuning display glitches. Use Crown's website or Hi Qnet Audio Architect's built-in firmware updater. 

Tuning Display Location

• Some tunings are not on the "channel" level but instead in the Input > Output Matrix or Crossover/EQ blocks.  
• Make sure you're viewing the correct DSP block where the tunings are applied.  

Hardware Fault

• Rare, but​​ possible: If all else fails and channel 1 tunings consistently misbehave, it may be a hardware fault or DSP issue in the amp itself.  
  Try swapping speaker outputs to test if the issue follows the channel or the physical output.  

Factory Reset (last resort)

• Back up your current settings/presets.  
• Perform a factory reset on the amp.  
• Reapply firmware and settings.
