AMPLIFI 150 just as a speaker, w/out Bluetooth


Recommended Posts

Is there a way to connect music output from device (phone, etc.) to AMPLIFI 150 via Mini-Stereo Audio jack cable?


There is an "AUX in" and "Guitar IN" ports that I assume would be the only there a specific converter cable I would need?


If the answer is "no", I hope Line6 will add one in future model.  I realize "just as speaker" may be a minor feature of this guitar amp (vs. Guitar amp itself!) but they do advertise it's use as a speaker on steroids (which is a nice feature for me).  It would be really sweet if a DIGITAL IN could be added, although probably limited users (but FLAC files would probably sound even better).


I like my Amplifi 150 but bluetooth connections have always had issues (intermittent disconnect, very limited distance/range) with all devices I've used (iphone&ipad/iOS, Samsun S6/andriod, Windows 10). Not saying it's Amplifi issue, but in general that's my experience).  Sometimes it's smooth and solid, but seems prone to "breakage".  Another fundamental issue I've experienced with Bluetooth (I can't say I've had this with Amplifi, but other BT speakers/headphones) is "pitch change" where the sound warps/changes pitch....unbelievable this was considered "OK" for music quality (it feels like cheap low-res MP3 marketing of the 90s all over again).

I'm not going to be able to address all your concerns but I had the 150 for a while and found The bluetooth connection issues were awful right after release but after getting firmware updates they were pretty darn stable.


As you have already noticed, Bluetooth connections are finicky across all devices. In general, ALL things on all devices with Bluetooth might "go to sleep" after a given point in time if they are not actively being used but they wake up (reconnect) when you try to use them. I believe this is a power saving feature but it does cause a noticeable delay before you get the response you are expecting.


The "guitar in" won't be stereo. It's probably Tip-Sleeve only for guitar. I don't recommend running music in that way.


The Aux in on the back panel (I'm pretty sure) is the 1/8th inch Tip-Ring-Sleeve jack you would use to connect your MP3 player/phone/external player to the 150. You should only need a 1/8 to 1/8 male cable. I think you have to push down on the main volume control to adjust the volume for the aux in jack. The color circle should be a different color for AUX than the color ring for the volume control.


I agree with your very last sentence about acceptable quality. I believe Bluetooth was originally intended only for wireless headsets to be used with phones, not music quality. In my opinion the technology got hijacked for music because it was accessible and because it was believed average folks wouldn't notice the quality issues.


Take what you need from my rambling and leave the rest behind :-)
