Equipment: Bose L1 model 1s with B2 sub Bose T1 'Tonematch' Engine Guitar: Alhambra 7Fccwe2 Electroacoustic Flamenco Guitar
Nice to be back on the forum! So, I decided to check the specs for inputs/outputs for the T1 on the Bose website where a couple of things dawned on me. Part of it states:
Mic/line inputs (1 – 3) feature combination analog connectors accepting balanced XLR or unbalanced ¼" TRS audio cables
My first little question concerns the "unbalanced ¼" TRS audio cables" part. Is it imperative that the TRS cable be 'unbalanced' What if I use a 'balanced' TRS? Will this greatly affect/distort the sound/signal??
Secondly, and possibly embarrassingly....(I say this because I never checked the imput/output specs for the T1 in the first place which seems like a juvenile error of the highest order) up to this point, I've been using Mogami jack-jack Gold series instrument cables going from my Flamenco guitar into the T1 Engine which are not TRS.
In any case, Is this a big NO NO? Am I doing my guitar and overall sound a big disservice using this type of cable??
Finally, with regards:
Line inputs (4/5, L/R) for analog stereo connections to keyboards, mixers and computers. Inputs accept balanced ¼" TRS cable.
Sometimes if I'm playing with other people and using other microphones and instruments I will run my guitar (using the same Mogami cable) into line input 4. Again, the same question applies - Is this a big NO NO? and furthermore, should one even run the likes of an acoustic/classical guitar through this channel in the first place?....is this a bad idea because there's a fair bit of noise/static coming from the speaker when using this channel combined with said Mogami cable and it only becomes more amplified when when I start using effects - reverb,compression,chorus etc (Perhaps I've answered my own question with this description!)
Once again, thanks for all your time! I'm still in the beginner stage of understanding audio so hopefully someone can provide some feedback for me!
It's also occurred to me that there's possibly is no such thing as an "unbalanced 1/4 inch TRS" like it says in the specs!? maybe someone can clear that up??

I tried to find technical details for you guitar. From what I could find, it appears that your guitar uses a Fishman Prefix Pro-Blend system. I couldn't find any sign that the output is balanced so I'm going to assume that it is unbalanced. This means the appropriate cable would be 1/4" Tip-Sleeve like this.

This is unfortunate terminology. It should read unbalanced 1/4" Tip-Sleeve audio cables. I'll report that to the web team.
What if I use a 'balanced' TRS? Will this greatly affect/distort the sound/signal?
The T1® Channels 1, 2, 3 1/4" inputs are unbalanced. There is no harm in using a balanced cable, but since the inputs are unbalanced there is no advantage (or detriment) using a balanced cable.

You're fine.

There's no reason not to run your guitar into T1® Channel 4. The output of the Fishman pickup system should work. There's no reason for more noise/static using your cable with this channel.

Kevin, from what you've written and what I found, your guitar output is unbalanced. A good quality 1/4 Tip-Sleeve cable is all you need to connect your guitar to any of the T1® 1/4" inputs.
Ah ok, I see! Thanks for the clarification! I guess the slight mis print on the specs led to part of the confusion and threw me a little. Nonetheless that's all good and thanks as always for the patience and time to read down through the queries! Guess I've only really realised that guitars give out balanced or more commonly 'unbalanced' signals - hence the TR instrument cable and yes you're correct it's is Fishman Pro-Blend Matrix system used!
Actually, just one further question while on the topic - Is it ok to use xlrf-TRS to connect vocal mics (sm57/58) OR large diaphragm condenser mics (specifically the AKG p220.....or any mics for that matter) to the tonematch T1 engine through either the line input OR through the combo mic/line inputs?? I ask this in reference to the T1 tonematch but also as a general question for all mixers. Is one losing signal input (or anything else) with such cables or is it ok??
I ask because I was thinking whether it is possible (or wise!) to use channel 4 and 5 on the tonematch (with said cable) to group two sm58's (with said preset) for vocals to free up the other channels for (i) guitar input and (ii) two mics for a cajon.
Sorry if this has been asked previously but as always thanks a million!

You see that you need an impedance matching tranformer. Please follow the link for more details.

See the article linked above.

I would prioritize and use T1® Channels 1, 2, 3 for vocal microphones. If I had other inputs like guitar and cajon, I'd route them to Channel 4/5 using the impedance matching transformer. Some people here have run two microphones into one channel, but the singers must sing at similar volume for this to work.

Kevin.
Remember, you also have a 1/4" balanced balanced input on the Model 1S power stand. You could use an impedance matching transformer and a microphone - then use that for your cajon.
Hello,not to confuse the issue.I have a Taylor 714ce and according to Taylor the ES2 pickup system is a Balanced output.Before I knew this fact I would use a 1/4 tr to 1/4 tr to plug into T1 ch 1,2 or 3 and it sounded great,but when I found out the ES2 output was balanced,I started to use a 1/4 Trs to Xlr cable.I couldn't believe change in volume of the guitar. The sound level increase was amazing.
When I play my Ovation with the Fishman Pick ups which are unbalanced I run 1/4 tr to 1/4 tr whicn sounds great also but it doesn't carry that same volume as the Taylor with the balanced.I did read somewhere on one of these threads that by using the 1/4 unbalanced you lose the benefit of the db gain that is available.
Steve.
And just for the record I am not a technical person at all.This site has provided me with great information and the speedy replies by staff an contributors is excellent.
