T8S ToneMatch Mixer Aux Output to S1 Pro

Use the T8S Aux Output to send a monitor mix to the S1 Pro System

Here's a quick overview of how you can connect a T8S to an S1 Pro

1. Leave the T8S and S1 Pro turned off until you have things connected
2. Connect the T8S power supply to the T8
   1. Leave the T8S and S1 Pro turned off until you have things connected
   2. Connect the T8S power supply to the T8S
   3. Connect the T8S Aux Output you are using for the monitor send to S1 Pro channel 1 or 2
      

      
      

      • Use a 1/4 inch Tip-Ring-Sleeve cable for best results
        
        
   4. On the S1 Pro channel:
      • Turn off the reverb
      • Set both tone controls to the center position
      • Set the channel volume off
   5. Turn on the T8S
      • On the T8S
        1. Set the Rotary Selector to PAN/AUX
        2. Press the CH EDIT button for each channel you are using and pan the input hard RIGHT
        3. Note: Steps 1 and 2 above are one-time-only. You don't have to change this unless you get another S1 Pro and want to run in stereo
   6. Connect all your sound sources to the T8S
   7. Turn on the S1 Pro
   8. Bring up the channel volume on the S1 Pro to about 11:00 o'clock
   9. Control the volume using the T8S Master Volume
   10. If you see the S1 Pro channel 1 light turning solid red occasionally, turn down the volume on the T8S
   11. Or if you see the S1 Pro channel 1 light turning solid red frequently, turn down the volume on the S1 Pro

   
   
   

   
   

   On the S1 Pro System, for each channel you are connecting to the T8S ToneMatch Mixer use these settings while you are setting up.

   

   • 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.

   S1 Pro+

   You can also connect to the Channel 3 Aux input. For best results, use a 1/4 inch (6.3 mm) Tip-Ring-Sleeve cable.

   

   
   

   
   

   Gain Staging

   Using a Bose device as the source

   When connecting a ToneMatch Mixer or an S1 Pro System Line Out to an S1 Pro System channel 1 or channel 2

   Set the volume control to 10:00 o'clock with 1/4 inch (6.3 mm) Tip-Ring-Sleeve

   The signal strength from a ToneMatch Mixer or an S1 Pro System Line Out is sufficient to achieve the maximum usable volume from the S1 Pro System

   Control the overall volume from the ToneMatch Mixer or the first S1 Pro System. If you use an XLR cable, set the volume control to 9:00 o'clock

   Using a third-party source (not a Bose device as the source)

   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. The exact value (-18 dBFS to -20 dBFS) may vary depending your location.
      • 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 indicator 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 third-party device (e.g., mixer or another line-level source) should I use the XLR or 1/4 inch inputs?

   • The S1 Pro 1/4 inch Tip-Ring-Sleeve inputs are best suited for line-level balanced inputs. This is a better match for the signal level.
   • The S1 Pro XLR inputs are best suited for microphones.

   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. From the source, 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.

   
   

   
   

   
   

   Alternate Connection

   You can use an XLR cable (mic cable) from a Line Level Source (e.g., L1 Pro, S1 Pro+) to S1 Pro or S1 Pro+ channels 1 or 2 (XLR inputs), but the signal may clip, overload, or be too high to control the volume. To attenuate (reduce) the signal, use a -20 dB or -30 dB Pad
