Hi people,

To use the line out for live use, e.g. going into a PA, do I need to go through a DI box, plug straight in setting level with master pot or ..........................?

Anybody using the line out?

Thanks

well, there is no line out on M1, just phones (and USB which is of no use on live gig).
I'm not sure how PA could handle this, plus you mute internal speaker when plugging phones jack.
I wouldn't use M1 for live gig, but I'd mic'd it if I had to gig with it.

Thanks man,
just wondered, for those times when I can't haul loads of gear.
The manual says the headphone out doubles as a line out, this doesn't make sense to me 'cause surely it isn't line level..............

Fender hasn't released the specs on the Mustang amps yet but typical headphone jack output impedance levels run at about 30 ohms and below where as line-level inputs are typically 1k - 10k ohms with the latter being the more standard.

Because of the higher voltage and lower impedance of headphone outputs, using the headphone out as a "line out" requires keeping the headphone output volume set low, so as not to overload the line-level input. This is controlled by the Mustang's Master Volume knob.

---

If your running this to a mixing board, it should have meters and "peak/distortion" indicators the will help set the level coming from the amp. Set the amp's Master Volume to "0" and the mixer's channel to "0db" and EQ at mid positions.

Using your loudest preset and the guitar volume at about "7", slowly turn up the amp's Master Volume until you get a good signal w/o flashing the peak indicators and below 0db on the meters.

---

If your running directly into an audio card on your computer, you can use the stand alone version of the Graphical Audio Analyzer software (there is also a buggy VST) which is freeware. Going into the red isn't necessarily bad - but signals that hit the top (0db) indicate digital distortion (very ugly sounding). Therefore you should keep the loudest signals so that they only occasionally go over -10db (around -6db). Here's a pick of the stand alone version of Graphical Audio Analyzer:

You can also run Graphical Audio Analyzer right along side FUSE to help you when writing and tweaking presets so that all your presets will have the same general volume, whether they're for death metal or acoustic.

Don't try and run it along with a DAW else the DAW won't be able to open the device and will throw an error.

Well, it's a $100.00 amp... I'm starting to wonder if there might be a way to hack a line out from the headphone jack. One that doesn't cut the signal off from the speaker. On my last amp, a Vox VR30, I permanently installed a Behringer UltraCab DI by tapping into the speaker output and adding an XLR jack to the back of the amp.

p90sdude is correct.

You can use the headphone jack as a line out as long as you keep an eye on the input levels on whatever you're routing to. You want to make sure there is no distortion.

I realize this is an old thread, but that was such a good explanation I'll revive it seeking clarification on the same topic...

I understand all above... I don't have a mixer, but I can check the levels on a preset with the software in the post from TwangManager by going from the Mustang into my sound card.

But then, after checking the levels, I want to go directly out from the "line out doubling as phones" jack on the Mustang I to a powered monitor speaker that accepts Balanced input on either an XLR or 1/4 inch input... both are labeled balanced. I have read an explanation online of what balanced means.

Is the signal coming out of the phones jack on a Mustang I Balanced?

If not, will I have any problems trying to run it into the inputs labeled balanced on my powered monitors... Yamaha HS80M's.

I don't want to go from Mustang to the sound card and then to the speaker... I just want to check the levels of my preset in the computer, then disconnect from the sound card, and with a different cable...not purchased yet, go from the Mustang directly into the Yamaha HS80M's.

Why do I want to do that?... because the speaker in the Mustang I is pretty terrible. I knew that was a risk when I bought it... I bought it as a stop gap between amps, but honestly the speaker is so bad I hate playing through it. I like the Fuse software, and I like the emulations, but I hate speaker distortion. I think my monitors will play the speaker emulated output from the phone jack without the speaker distortion I get from the built in Mustang I speaker.

Well, hell... as soon as I posted that I noticed a line on the Yamaha site that says my speakers' accept both balanced and unbalanced input, so I guess I answered my own question.

Any suggestions still appreciated.
