This is guide for people who use their Bose Portable PA in Duo applications.

In addition to the notes below that apply to Duo shows, check out:

Ideal Application: One L1® per Performer

Running one L1® for each performer in a duo format is a wonderful experience for both the performers and the audience. This gives the audience all the benefits of localization, and the best possible monitoring experience for the performers. Click on either of the pictures below for detailed descriptions of the stage layouts shown here.

Connecting Two T1 ToneMatch® Audio Engines to a L1 Model II

The L1 Model II can accept two inputs.

Model II inputs

This makes it easy for two performers to connect their own T1®s to a L1® Model II Power Stand.

ToneMatch® Input

The ToneMatch® connection is specifically designed for a T1 ToneMatch Audio Engine. The ToneMatch® cable is supplied with the T1 ToneMatch Audio Engine and uses a male Ethercon connector at both ends.

Analog Input

Model II/Model 1S analog input

The Analog connection is a ¼ inch phone jack. You can use this for a second T1® using the T1® Analog Master output (¼ inch phone jack).

This connection is made with a standard ¼ inch jack instrument cable. This can be Tip-Sleeve or Tip-Ring-Sleeve connectors.

Set Power Stand Analog Input Trim to 3 to have approximately the same level as you would have if you had connected with the ToneMatch® connection. You may have to adjust this, but 3 is a good place to start.

Note: A T1® connected to the the Analog input will require the optional T1 ToneMatch® Audio Engine power supply.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.

Tip-Ring-Sleeve to Tip-Ring-Sleeve

¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)

This should work fine but a balanced connection (immediately above) is preferred especially if you will have cable runs in excess of 20 feet (6 meters) or if you hear line noise, hum or hiss.

How do I connect an Analog Stereo Source to an L1®

Backing Tracks — This article covers connecting devices like CD, DVD, mp3, iPods to your L1®

L1® Model II: Can I run a Stereo Source to the Power Stand

A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the Model II.

Even though a ¼ inch Tip-Ring-Sleeve connector can carry a stereo signal this is not how this physical connection is used on the Duo Power Stand.

The analog input on the Model II is balanced, and will therefore subtract the Left and Right signals on a stereo cable and you will hear an L-R (Left minus Right) signal in the Model II.

You cannot 'get through the gig' this way if you are a DJ or if you need to run prerecorded music or have stereo inputs.

Using a Mixer

If you are using a mixer instead of a T1 ToneMatch Audio Engine use the mixer to create a mono output and send that to the Model II Power Stand Analog input.

  • If there is a stereo/mono switch then use it and send the mono output to the Model II Power Stand Analog input.
  • If there is a Left/mono output then use that and send it to the Model II Power Stand Analog input.
  • If there is no way to create a mono output then pan all your mixer inputs all the way to one side (e.g. Left) and then take the mixer for that side (e.g. Left) output and send it to the Model II Power Stand Analog input.
