Marshall Gateway is a remote control and device management app for use with Marshall CODE Series amplifiers.

Connection with CODE is via Bluetooth Classic for streaming audio from your music library and Bluetooth LE (iPhone 4S, iPad 3rd Gen) for real-time control of your amplifier settings.

Gateway can function independently of CODE to create and manage presets that can be sent to CODE when connected.

Love it

So much easier than trying to fine tune through the amp itself. You can tweak the hell out of every setting. Turn things off and on easily, save and name your presets easily, sync with your amp easily. All via bluetooth. It took a coouple of reboots on my photo to get bluetooth working, but all is well now. I just recently starting using the playback feature to isolate a portion of a song in my iTunes library and slow it down to 50% speed. Awesome. One star because you don't actually own the amp that the app was specifically made for? Really?

Just bought the code25. I had to do a software update to the amp via usb and computer. I then was able to pair with my iphone and Ipad. However, my iphone with the app still does not work. It will pair but app is frozen. My friends iphone and my ipad work great. It seems truly amazing what the app and amp can do. Also to pair hold down 2 buttons on the amp. It will start flashing to pair. I can even use the riffstation app while using Marshall app. Hope this helps.


Better than using the amp, but...

Still a little clunky to manage presets between gateway library on computer, app, and amp.
REALLY NEED a way to copy the WHOLE phone bank to the amp bank. not just one by one. I don't want to manage amp and phone separately. If I shuffle presets on the gateway the sequence on the phone changes obviously, then the amp (and stomp switch) are different. And if I tweak on the amp, I want everything to go to phone/cloud.
I want amp and phone to match in case my phone is dead or elsewhere.

An auto-sync (that can be turned on/off) between amp and phone bank would be even better.

Bluetooth doesn't always connect.
iPad 2 does not even find the amp.

Phone/Message sounds come on speaker while playing.
