Overview
ToneMatch® Port
For connecting the T1 ToneMatch Audio Engine to the L1 Model 1S.
The port sends electrical power to the T1 and accepts digital audio from the T1.

The connecting cable has a male Ethercon connection at each end that looks like this.
For details about the cable see: T1® Cables
Analog Input
The Analog input is a ¼ inch balanced input jack.
Analog input trim (volume, or gain) control
There is a trim control for the analog input.
With the audio on the input signal at or near its most intense, adjust the trim level on the Model II analog input until the LED begins to turn from yellow to red. Then reduce the trim level until the signal LED is predominantly yellow with only brief changes to red.
Can a stereo signal be used with the analog input?
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 L1® Model 1S 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.
Analog Input for Second T1 ToneMatch Audio Engine
The L1 Model II can accept two 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
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.
Analog Connection from the Second T1® to the Model II Power Stand
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.
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.
Start Up / Cycle Time
The Model 1S takes a few seconds to fully boot up and then turn the audio on. Make sure you are waiting the right amount of time.
If you do reset the system be sure to wait a full two or three seconds between turning it off and turning it back on.
Height
The fully assembled height of the L1 Model 1S is 79.5 inches. (201.93 cm)
Clearance required to assemble is approximately 84 inches. (213.36 cm)
Input Panel
- Analog input, trim control and signal/clip LED
- Line-level analog input accepts 1/4" TRS phone cable. Can be used for instruments or other audio sources like DJ mixers, MP3 players, computers or DVD systems. Trim control lets you adjust the level of analog input signal. Signal/clip LED indicates status of analog input signal.
- Bass module out
- Delivers amplified bass output signal to one or two B1 Bass Module bass modules or one B2 Bass Module. L1 system automatically adjusts equalization appropriately when bass modules are connected.
- ToneMatch™ port
- Digital audio and power connection for ToneMatch audio engine. Use with included ToneMatch cable.
No Speakers Attached
If you want to record using USB without using the L1 Cylindrical Radiator® loudspeaker or B1 Bass Module or B2 Bass Module ...
You can certainly run the L1 with all, some, or none of the speakers connected. With no speakers connected it will happily serve as a big power supply for the T1. You are in no way risking damage to the unit by doing this.[1]
Identifying this Model
- Retractable legs
- Provide stability for streamlined L1 Model 1S power stand and loudspeaker. Four retractable legs fold out of power stand simultaneously for quick setup and compact transport. Small footprint also frees up room on tight stages.
