Some people have expressed concern because the T8S ToneMatch mixer does not have ToneMatch (digital) connections to L1 Model 1S and L1 Model II.

I've taken the time to test this carefully.  To my ears, there is no audible difference between the digital and the analog connections.

The background and some notes about how I tested follow below.

Bose has told us

We tried to make it (full ToneMatch port for digital output) happen for the T8S but powering the T8S from an L1 was not meeting our requirements so we opted for an external power supply which ships with the T8S. While the digital connection is nice, your experience will be fine with a balanced TRS connection between the T8S and L1 Model II.

The best way I know to detect differences in sound is to do an A/B switch back and forth instantly. Even a few seconds between listening events can lead to misconceptions.

There's no way to make a direct comparison of digital and analog on the T8S because there is no digital output. But on the T4S, you can switch instantly between digital and analog. So I started my A/B listening tests with the T4s.

Connections from the T4S to the L1 Model II (and later L1 Model 1S)

  • T4S Ethercon cable from T4S Right Channel to L1® Model II power stand ToneMatch (digital) input
  • Balanced 25-foot cable from the T4S Left Channel analog output to the  L1® Model II power stand analog input
  • USB B from PC directed Left to Channel 3
  • USB B from PC directed Right to Channel 4
  • Channel 3 panned hard Left
  • Channel 4 panned hard Right
  • Levels so the volume was the same whether I was running analog or digital
  • Tested by alternating Channel 3 and Channel 4 MUTE buttons so I could switch back and forth instantly
  • Swapped source Left and Right (USB B from PC)
  • Tested with L1 Model 1S
  • Listened at moderate and loud volume

I tried several high-res and lossless audio files on the computer and switched back and forth from analog to digital and back. I made sure I could not see the buttons as I swapped A/b, so I had no visual cue to tell me whether I was listening to analog or digital. I could not hear a difference.

Then I tried comparing the T4S and the T8S. This was harder to do because I couldn't swap back and forth instantaneously without adding a switching device into the signal chain. I could not hear a difference between the T4S digital and the T8S analog outputs on the L1 Model 1S or Model II.

Very interested in how this plays out. Don't get me wrong I see where Bose was coming from as they were not gonna be happy with the T8S since the L1 Stand was not capable of supplying enough power for the mixer. I don't think the solution they came up with was the only one they could have but I believe you when you say it still sounds great I'll just want to hear more real world trials from people who know how they should sound already. 

I need more channels and do this already sub-mixing into my T1 with great results. The T8S is attractive because I'll have more control over my channels and a smaller profile to lug around. I am however not willing to sacrifice any overall sound to do this. I'm a happy Bose L1 user for over 5 years so just for channel sake I don't want to take a step back in overall sound.

I hope this plays out as you say and is wonderful sounding with no compromise. I'll get in line to get one and I'll take advantage of the 45 day trial for sure!

So....I have been using BOSE for years now in my show so I am willing to test this out. I have one on order but will keep my two Tonematch mixers until I can confirm, the analog out is as good as the digital. I played last night at a very quiet intimate venue and my system sounded like you were listening to a record....so cool. 

 

Hi there !

Not been on the Bose forum for quite some time but I have just noticed there are some new Tonematch mixers.

i have a blues acoustic duo, and we bought one Bose L1mkII, two B1 bass modules, and each use a T1 Tonematch mixer, about 8yrs ago - and love using them. In some pub gigs, with a small PA system already set up, and no room to set up the L1 additionally, we have often used just our Tonematch mixers with the in-house PA and still got great results. Our Tonematch mixers are awesome !! We would plug one directly with the digital input, and the 2 Tonematch would go into the analogue input. I could never tell who was going through the digital/analogue channel, to be honest.


We've started a new discussion for the remaining part of this post. 

Please see: Considering T4S/T8S Stereo options 

Thank you.

Hi,

Just received my new T8s and starting to find my way around it.

As recommended, the first thing I did was to update the firmware to the latest version. 

However, with no digital connection capability to my L1 Model IIs, there is now no way to check / update the firmware in the L1 Power Stands.

Is there going to be another way of doing this?

Hi SnakeHips,

Here's how you can check if you need to update your firmware.

What version level is your T1 ToneMatch® Audio Engine? (T1® for short)

  1. Turn the Rotary Selector to Prefs


  2. Press the first button


  3. Turn the first button until you see Versions
  4. Press the button


  5. The versions for the firmware will be displayed. The versions shown below are sample values.
    See:T1 ToneMatch® Audio Engine Firmware Updates for the latest firmware


  6. See:T1 ToneMatch® Audio Engine Firmware Updates for the latest firmware



Right now the latest T1® firmware is 1.8.

What have you got?

Notes: What version of the T1® Firmware do I have?

ST

I think he was referring to the firmware on the L1 Power Stand. If you only have a T8S you have no way to check or update the firmware on the Power Stand.  I think a firmware upgrade was required if you wanted to use the B2s with an older Power Stand. Newer ones likely have the correct firmware. 

Yes, that's correct, I was referring to the L1 Power Stand.  I 'm currently using B1 Bass Modules, so not a problem for me at the moment

, I may not be able to without a firmware upgrade on the Power Stand.

But could be a problem for some people (including myself in the future) who wanted to upgrade to B2s and had "older" Power Stands with old versions of the firmware.

Hi SnakeHips,

If you mean the Model II Power Stands.



What version is your Power Stand?

  1. Turn the Rotary Selector to Prefs


  2. Press the first button


  3. Turn the first button until you see Power Stand


  4. Press the button
  5. The version is displayed.


The latest versions add support for the B2 Bass Module

The latest Power Stand EQ: 1.0.4
The latest Power Stand Firmware: 1.4

If you have Power Stand Firmware 1.4 or 1.5 you do not need to update your Power Stand.

1.5 Some Model II Power Stands have been shipped with version 1.5 - if you have this, you are fine. Do NOT update your Power Stand.

1.4 If you are at 1.4 - that is the latest user-updateable version. Do NOT update your Power Stand.

If you do not have version 1.4 or 1.5 update your firmware at this link:

L1® Model II Power Stand Firmware Updates.

.Hi Freshwuzhere,

Welcome to the Bose Portable PA Community.

Hi ST,

How does the Tonematch T8s communicate with the L1 through an analogue cable?  Seems surprising that it knows the model and firmware.  Are you sure this isn't referencing a T4s? with the proper Tonematch connection?  Mine says "Not Connected".....



FOR Firmware UPDATES ONLY  (T8S to L1 Model II Power Stand)

You can use a ToneMatch cable (or ethernet Cat-5 or Cat-6) to connect to a L1 Model II or L1 Model 1S Power Stand.

Do NOT do this at a gig. It may pass audio for awhile, but the connection for audio is not stable and will cut out.

This digital connection is fine in the unlikely event you need to check or update the firmware on your L1 Model II or L1 Model 1S power stand.

Does that help?
