T1 ToneMatch® Audio Engine to Two Model 1S Power Stands

T1®  This information is applicable to the T1 ToneMatch® audio engine
Model 1S This information is applicable to the L1®  Model 1S
Model II This information is applicable to the L1®  Model II
Please note: Bose recommends that if you have two Model 1S systems using the same source, that you place the Model 1S systems at least 20 feet apart (6 meters). This is to avoid Multiple Source Interference

Running two Model 1S systems with the same source is running Dual Mono and not recommended unless the L1®s are at least 20 feet apart.

System 1

Connect the first system with the ToneMatch cable that came with the T1®.

  • T1® ToneMatch port to the Model 1S Power Stand ToneMatch port.
System 2

Connect the second system with a ¼ inch jack Tip-Ring-Sleeve cable

  • T1® Master Output to the Model 1S Power Stand Analog input
    • on the Model 1S Power Stand set the analog input trim to "3" and adjust as necessary to get a good balance with the other system.
    • For best results use a Tip-Ring-Sleeve (balanced) connection.

      You can use a Tip-Sleeve (unbalanced connection) but the Tip-Ring-Sleeve (balanced connection is preferred).

Stereo

This article will primarily be of interest to DJs.

You can run a two signals (for example stereo tracks) through a single T1 ToneMatch® Audio Engine out to two L1® s. How you do that will depend on your input, USB or Analog. Both of these methods involve sending one track to the Main output, and one track to the Aux output.

Analog

Summary

In this case you connect one half of the stereo pair to one T1® Channel (1, 2 or 4/5) and let that be amplified through the T1® Main output. Then connect the other half of the stereo pair to another T1® Channel. In this example I did that on Channel 3. By routing Channel 3 exclusively to the T1® Aux output, you can keep the Stereo channels left and right separated.

Once you get the balance set you will probably want to control the overall volume from the sound source. It is not really convenient to do that in the T1® because there is no joint control for both Main and Aux outputs.

T1™ Aux

Using Aux to send a signal exclusively to a second System

Using a T1 ToneMatch® Audio Engine with two L1® s, you may want to send an input to one System, but not the other.

In this example, we are taking an input in Channel 3, and sending it to Aux, and not to Main.

  1. Set the Selector to Aux
    T1Aux.png
  2. Press CH Edit for Channel 3

  3. Press button 1 to enable Aux
    T1AuxSplit03.png
  4. Press button 2 to see the Tap menu

  5. Turn the Tap setting to Pre: With EQ & FX. Press the button to Select.
    T1AuxSplit05.png
  6. Set the Channel Volume to 0 (zero).
    I set the Volume to 0 to avoid unwanted consequences of accidentally hitting Mute. Just to be safe, I also Mute the channel.

  7. Adjust Aux Volume if necessary.
    You will probably end up at or near 100%

USB

Playback stereo tracks from a USB connection from your computer

USBtoStereoL1Model I.png

If you need to playback stereo tracks from a USB from your computer, this how you can do it.

NOTE: You will want to control the volume and balance from your computer. It is not convenient to do this from the T1 ToneMatch® Audio Engine in this configuration because one of the channels is routed through the T1 ToneMatch® Audio Engine Aux buss and the other is through the Master. It is not easy to control both of these at the same time on the T1 ToneMatch® Audio Engine.

Equipment Required

  • L1® Classic/Model I or Model 1S or Model II or Compact (L1® LEFT)
  • L1® Classic/Model I or Model 1S or Model II or Compact (L1® RIGHT)



Initial Connections

Turn down the outputs and volume

Start with your computer with the volume set all the way off, muted or at least really low. Things can get loud very quickly if you are not careful.

On the T1® turn down the Master Volume and mute all Channels.

Physical Connections

Make the following connections. If you are running two L1® Classics or L1® Model I or L1® Compact Systems, then you will also need the optional T1 ToneMatch® Audio Engine power supply (not shown below).

Model II

If one of the L1®s is a L1® Model II then you will not need the connection marked "To L1 RIGHT". This will be replaced by the ToneMatch® connection to the L1® Model II.

USB to PC

We want to split the USB signal from the computer so that

  • the Stereo Left channel goes through Channel 4/5 to Aux and from there to an analog connection to an L1®
  • the Stereo Right channel goes through to Master and from there to an analog connection or digital connection to another L1™

Prefs

  • Turn the main selector to Prefs.
  • Select USB from PC

T1PrefsUSBfromPC.png

  • Set Left: Ch 4/5
  • Set Right: Master

Channel 4/5

  • Press Chan 4/5 CH Edit
  • Rotate the selector to Aux
  • Set the Level to 0% (not bypass)
  • Set the Tap to Pre
  • Mute this Channel. You can turn down the level as well. It you leave the Mute off then you will be sending both Left and Right stereo signals to the Main output.

Setting the Relative Levels

  • On the Computer: Start playing a track. Turn up the volume on the computer a little. You won't hear anything yet.
  • On the T1® Turn up the Master Volume. You should be hearing the Stereo Right channel.

Work the volume on the computer and the T1® until you are happy with a workable volume level.

  • On the T1® Turn up the Aux Level. Your setting will look something like this. The actual value you set may be different. That's okay.

USBtoStereo_3.png

This is the Stereo Left channel. Bring up the volume until it matches the output from the Master. Note: This Aux volume is completely independent of the Master volume. This is why you want to set it to be equally balanced with the Master. You will then be able to control the balance and level from the computer.

Download Shared Scene

Here is a Shared Scene you can load into your T1 ToneMatch® Audio Engine. If you have been following along and have set up our T1 ToneMatch® Audio Engine with the settings above, you do not need to download this Shared Scene. I just included this as a convenience in case you wanted to try the Shared Scene system.

This scene has very generic settings for Channels 1,2 and 3 and the settings discussed in this article for Channel 4/5.

  • Channels 1,2,3 are set to Vocal Microphones: Handheld Microphones - no effects, muted.
  • Channel 4/5 is set as described above with USB routed to 4/5 routed to Aux. This is muted so that this Channel is not sent to the Main output.

Please read the entire article before using this Shared Scene. It is provided as a convenience to save you some time is you want to have the same settings.

Warning

This is an experimental file and I strongly recommend that you back up all your scenes before loading this one, just in case you overwrite something by accident. I have tested this and it works in my environment, but I cannot accept responsibility for any issues you may have when you apply it to your T1 ToneMatch® Audio Engine

You will need to understand how to use the L1 Software Updater program to load this Shared Scene.

Things you must have and understand to use a Shared Scene

Get the L1® Updater Software

L1® Updater Software application. (two versions available)


Warning

If your firmware update is not successful - Caution

After you update the T1 ToneMatch® Audio Engine or L1® Model II firmware, if you see a window on the PC that says the update was not successful, you should:

  1. turn the L1 and T1 off
  2. wait three seconds
  3. then turn the L1 and T1 back on

Do this before trying the update again!

This allows the L1 and T1s to re-establish a good copy of the software.

Source: If your firmware update is not successful - Caution

Here is a very simple Scene that includes the setup described above.

Variations

One Classic / Model I and One Model II

USBtoStereoPhysical 2.png

On the L1® Classic / L1® Model I set the Power Stand Input Level to 3. You may want to fine tune that a bit but it should be a reasonable starting point.

Two Model IIs

USBtoStereoPhysical 3.png

For the L1® Model II with the Analog connection - try setting the Analog input trim 3. You may want to fine tune that a bit but it should be a reasonable starting point.

Two Model 1S

USBtoStereoPhysical 3.png

For the L1® Model II with the Analog connection - try setting the Analog input trim 3. You may want to fine tune that a bit but it should be a reasonable starting point.


Two Compacts

For the L1® Compact connect to Channel 2 with the volume straight up. You may want to fine tune that a bit but it should be a reasonable starting point.
