Does the AM4 work the same way as the FM3 if you connect your phone via usb ie its full volume and you need to use the usb1/2 setting to control its volume?

if the above is true, can you map the usb1/2 to one of the 4 control knobs on the device?

Can someone check whether USB audio output comes out of the Insert Send ?

Yes it will. The Insert is analog, so it is after the D/A conversion. Keep in mind though that the insert is in series so it will block the signal from getting to the Output jacks unless you bring it back in through the Insert Return jack.

I do not believe the block diagram in the manual.
As you probably know, it was wrong about the placement of the headphone out.

Have you tried the USB 1/2 output on an actual AM4 unit ?
Does it come out of the Insert Send ?
Thanks !
 
It has nothing to do with the block diagram. The AM4 insert is all analog. USB audio is digital so it has to be mixed in before the D/A conversion. The insert is after the D/A convertion so any signal that goes to the Output jacks has to go through the insert first.

I did it last night with my iPhone! I jammed with my streaming music apps and Youtube backing tracks. You might need to adjust output levels of preset or amps, since it was noticeably louder than the playback for me. Props to FAS for using USB C! It is so easy to travel with and practice with music on most smart phones, PLUS have access to AMAZING TONES!

I understand you can plug your smart phone into the USB-C jack to get music into the AM4, but did you have to run a TRS 1/4" to TRS 1/4" cable from the Insert Send to the Insert Return for the music and guitar to show up in the headphone out?

So then no cable from Insert Send to Return should be necessary.
 
If you have nothing plugged into the Send jack, it is internally shorted directly to the Return jack. If you plug a cable into the send, the path to the Output jacks is broken and the signal is sent out of the Send jack instead.

I only used a regular headphone jack (I think its 3.5mm, correct me if I'm wrong) for output. I did not use any other connections. Hope this helps!

That’s awesome. I have an iPhone 13 with lightning port goin to usb-c on the am4 and I’m not having any luck get the audio to go to headphones. Does your iPhone have usb-c charging port? Maybe that why mine doesn’t work.
