T1 ToneMatch® Audio Engine / Aux
Contents
Overview
The output of any of the Channels 1, 2, 3, 4/5 can be sent to the Aux out. You can take the Aux out to provide a separate mix for recording or running to another L1 or separate amplification system.
Tap points where you can set the output to the Aux.[1]
- Dry: After Preamp: The completely dry (no processing) signal is routed directly from the preamp stage.
- Pre: With EQ & FX: The signal is routed from the preamp stage with applied processing.
- Post: After Fader: The signal is routed after the Channel volume control with applied processing.

No Reverb on Aux
Q: Why is there no Reverb on the Aux output of the T1 ToneMatch Audio Engine?
A: Hilmar-at-Bose writes[2]
- The T1 ToneMatch Audio Engine has lots of different effects units and normally they are unique to each channel. That means that the T1® has 4 individual dynamic processors, 4 modulators (chorus flanger, phaser, etc.) , 4 EQs, 4 delay processors, etc. The only exception is the reverb, which is shared by all channels.
- The AUX is also a per-channel control. That means if you turn up the AUX of channel, you expect to hear signals from channel 1 and only from channel 1. However, the output of the reverb processor contains the reverb portions of all 4 channels. If we add that to the Aux, you'd hear the reverb portions of all 4 channels and not only the channel that you are interested in. In most cases, this is probably not what you want.
- If you are familiar with conventional mixing consoles, you will find that the situation is quite similar. You can only route to an AUX output effects that are specific to a channel (normally these would be connected to the insert loop of this channel). The "shared" effects typically come into the board through an AUX return, which is not channel specific.

Problem: Aux output does not sound right.
What To Do:
- Check if the Aux output is configured for the desired tap point for each input channel. Refer to “Routing input signals to the Aux output” on page 26.[1]
Note: No reverb comes from the Aux output even if the tap point is Pre or Post.
- Verify that each input assigns the desired signal level to the Aux output.
Aux Out to a separate System
The Aux Out is balanced mono and suitable to connect to the S1 Pro System Channel 1 or 2.
For best results use a 1/4 inch (6 mm) Tip-Ring-Sleeve cable. A 1/4 inch (6 mm) Tip-Sleeve cable will have up to -6dB lower signal and be more susceptible to line noise.
Aux Out to a separate System
Aux Out to Headphones
The Aux Out is balanced mono intended to be connected to the balanced input of another device at line-level. This may also work with headphones but the volume will be very low and likely not loud enough to be heard over live stage volume.
If you connect to a stereo input, the signals for Left and Right may cancel out. This might not be an issue for headphones as the Left and Right signals are not combined.
Aux Out to In-Ear-Monitors
The Aux Out is balanced mono intended to be connected to the balanced input of another device at line-level. This may also work with headphones but the volume will be very low and likely not loud enough to be heard over live stage volume.
If you use an In-Ear-Monitor system that has built-in amplification, this may work.
If you connect to a stereo input, the signals for Left and Right may cancel out. This might not be an issue for headphones as the Left and Right signals are not combined.
