I seem to be having the same issues that a lot of people have reported, where I cannot get the Marshall Gateway app to connect to my Code 25. I've only had the amp for about a week and I cannot get the app to see it. ?
I can connect to the amp via Bluetooth using my phone (Pixel 3a, Android 11) and whilst connected, can use it as a BT speaker to play music from Spotify. However, nothing I do seems to get the app to connect to the amplifier.
-I've updated the amp to the latest firmware using my laptop/web browser.
-I've followed all the instructions in the Bluetooth Connectivity Troubleshooter to the letter (CODE - Gateway Bluetooth Connection Troubleshooting - my.marshall.com)
No matter what I do, or what order I install/uninstall/connect, the app will not see the amplifier. Everything works otherwise - I'm able to apply Patches from ? using a USB connection - and the amp sounds great. I'd just like to be able to control it from my phone.
Actually I'm totaly not interested in bluetooth connection, but of course I understand that it might be an essential prolem for some people...
But there are some other problems I'd like you to find good solution for.
1. Master volume. From 0 to 10% there is almost no sound, over 10% it becomes very loud.
2. Decreasing sound level with Volume pot results in decreasing USB signal level - not acceptable for players using USB output for recording in DAW software. It would be nice if for clean preamp gain at 2 and volume at 3 give recording level about -6 dB, now it is about -36 dB...
Best regards, Jacek.
P.S. What is a frequency range of CODE 25 speaker?
