Mesa Subway D-350!

[agedhorse]

If the plug is not fully seated (at either end), results can be totally unpredictable.

Just tried it again, I don't know what I did differently now but it works! I have been using TRS cables since I first tried. Only reason I can think of was the adapter might not have been seated/inserted fully.

Don't feel too bad, a TRS cable connector not fully seated has been the problem in more cases over the years than I can count. It is the first place I look when troubleshooting things like this these days.

Glad you're back in business!

Anyone compare the Mesa D-350 to the Aguilar TH-350? They are priced about the same so it's a fair comparison. The power ratings are identical on paper but I've read the Aguilar uses the same power module as a GK MB500 so it's power rating is a bit misleading on the conservative side. So does the Aguilar TH-350 have more power than the Mesa D-350 or is it also rated conservatively? I guess in the end it's more about sound characteristic preferences but I was also wondering about the power rating comparison.

Not sure but I have a Gk mb fusion 500 if anyone wants to send me a d350 to do a shoot out

Good reading, here:

Well, I already have the TH-350 and Zzounds just got few more D-350's in yesterday so I couldn't resist and ordered one. I guess I'll be able to answer my own question soon enough.

It’s the only way today. It costs to buy and it costs to sell. I took a hit on a brand new SW115 to get a SW210 next to it for an A/B comparo in my conditions. I consider it tuition.

Nicely made point...very few educational experiences are totally free...at least not IME.

I've got that buying part down pat, its that selling thing that has me baffled.

Because of your post, I checked out Zzounds. They have a very attractive 4-payment, no-credit-check deal. That made me decide to buy one. But before I pulled the trigger, I checked out Sweetwater. Turns out they have a demo for $70 less. Correction: they had a demo for $70 less. Money I didn't really need to spend, but I couldn't resist.

Dang you.

Some educational experiences can also be painful…

It's animated not the real occurrence.

Sorry about that, but you may thank me later.

I think you’ll like it. Really enjoy mine.

I almost bought that one then reverb had one cheaper that almost had me pull the trigger only to find a two week old wd800 that was mint for almost $500 off list with the warranty unregistered yet. I had to get that instead as it was too good to pass up but I'm still hoping to get a d350 as quick grab next time my funds free up.

Apologies if this has already been addressed in the thread:

When using the aux-in (via TRS cable) with headphones, does the aux-in signal remain in stereo, or is it summed to mono, as in the cabinet output?

I assume that the cabinet emulation is not applied to the aux signal, is only applied to the bass through the headphones (not through the cab or the DI, pre- or post-EQ), and is not switchable. Is this all correct?

I had a look at the manual (relevant sections quoted below in slightly abridged [...] form), but didn't see these questions explicitly addressed.

Thanks in advance for any clarification!

HEADPHONE OUTPUT
The SUBWAY D-350 includes a 1/4” (6.35mm) TRS tip-ring-sleeve headphone output jack, which will drive all common headphones and IEM earpieces between 8 and 32 ohms (and most well above 32 ohms). It is not necessary to have a speaker connected to the amp when using headphones... This output contains additional cabinet emulation circuitry. This output should not be connected to anything but headphones, earbuds, or IEM earpieces.

AUX INPUT
This amplifier is provided with a 1/4” (6.35mm) TRS AUX input. This TRS stereo jack properly sums left and right channels from an MP-3 player, i-device, or laptop, as many of these new devices do not contain adequate circuitry for proper summing. Note that for best performance, a 1/8” (3.5mm) TRS to 1/4” (6.35mm) TRS cable (also called a stereo cable) should be used... The level of this input is controlled by the MASTER VOLUME control, as well as the volume control on the external device such as the MP-3 player or outboard preamp.

This signal will not be present in the DI output.

DI OUT SOURCE SWITCH
This switch selects the signal source routing that is used to derive the direct output signal. In the PRE position, the signal is sourced directly from the input buffer... In the POST position, the signal is sourced from the output of the equalizer section and before the master volume control. Generally, for PA use, the FOH (front of house) engineer will probably prefer a PRE EQ send... If you use the overdrive capability of the amp, then the post position is a better choice, but you will need to work with your FOH engineer to ensure that the EQ you use on stage will work for the house mix.

The simple answer is that the signal you will hear in your headphones (just like from the speaker outputs) is mono. Any TRS stereo source signal is summed along with the bass signal (if present) to a single mono signal and that's what you will hear in both sides of your headphones (or from the speaker outputs). That mono signal will contain the combination of the left and right aux in input source along with bass signal (which is obviously mono too).

If you look at the signal flow diagram on page 22 of the D-350 manual you'll see this clearly. Also, if you look at where the cabinet emulation circuitry is placed you'll see that all headphone output passes through it. FWIW, the cabinet emulation circuitry only affects what you hear in headphones as it is not in the signal path for the speaker outputs.

I hope that helps. Agedhorse may have more details to add, but I think I hit the main points accurately.
