Power for the T1 ToneMatch Audio Engine
If your T1 ToneMatch Audio Engine is connected to an L1 Model 1S or L1 Model II, the T1 ToneMatch Audio Engine will get power from the Power Stand. If it not, you will need a ToneMatch Power Supply to run the T1 ToneMatch Audio Engine.
Cables
1/4 inch (6.35 mm) Tip-Ring-Sleeve
The T1 ToneMatch Audio Engine Analog Outputs and the S1 Pro System 1/4 inch (6.3 mm) inputs are balanced. For best results use a 1/4 inch (6.35 mm) Tip-Ring-Sleeve cable for a balanced connection. You can use a 1/4 inch (6.35 mm) Tip-Sleeve cable, but you will lose up to -6 dB in signal strength and you may pick up line noise.




On the S1 Pro System, for each channel you are connecting to the T1 ToneMatch Audio Engine use these settings while you are setting up.

S1 Pro Settings for mixer.jpg

  • Reverb OFF
  • Bass at 12:00 o'clock
  • Treble at 12:00 o'clock
  • ToneMatch switch OFF

You can adjust the Reverb, Bass, and Treble after you get your basic sound working.

Gain Staging

For each channel you are using on the S1 Pro System,

  1. Turn the channel volume off
  2. Connect your sound source
  3. Adjust the volume of the source device output to the reference or nominal output level.
    • On analog consoles this may be marked as unity or 0 dB.
    • On digital consoles this may be marked as -18 dBFS[1][2]. The exact value (-18 dBFS to -20 dBFS) may vary depending your location[3].
    • Refer to the manual for the source device for details.
    • If the source device does not have metering or indicators, set the output as high as you can without hearing distortion or seeing red indictor lights.
  4. While playing/singing as loud as you will during your performance, bring up the channel volume until you see solid green on the channel indicator light. Occasional flickers of red are okay. If you see solid red or you hear distortion, turn down the volume.

Combo Inputs

S1 Pro Channels 1 and 2 have combo inputs that accept
  • XLR (balanced mono)
    • Microphone or Line-Level inputs
  • 1/4 inch (6.3 mm) Tip-Ring-Sleeve connection (balanced mono)
    • Line-Level inputs
  • 1/4 inch (6.3 mm) Tip-Sleeve connection (unbalanced mono)
    • Line-Level inputs and instruments (e.g. guitars, keyboards, guitar processors, loopers)
When using a mixer should I use the XLR or 1/4 inch inputs?

When the S1 Pro Channel input lights hit red or you hear distortion, the signal is clipping and you've reached the maximum usable volume. With a mixer, if the XLR outputs are line-level and the 1/4 inch Tip-Ring-Sleeve outputs are line-level, it won't matter which type of cable you use. They'll both get the job done, although the volume control setting will be lower with the XLR connection. That doesn't indicate more headroom. The maximum usable volume is the same either way.
