Our four piece classic rock band is performing for a local variety show. We play a 50 min preshow set and then turn around and become the pit band to accompany the chorus and play walk offs etc.   I'm using my TM8 for 3 vocals, guitar, bass, keys, and Roland E-drums (7 inputs).  For the preshow we need to hear our vocals without any latency/delay that we get through the auditorium mains. So I ran the left main XLR out to two wedges hooked up in series.  By doing that, we were able to produce the mix we like without depending on an unknown sound engineer.  I then sent the same mix to the house mains by using the right main XLR out.  The problem is that the signal the house received was so hot that we had to back off the main output so much that we lost almost all head room for the output to out wedges.  Is there a way we can separate and create two  "master outputs" without creating another auxiliary mix that may or may not match what we send to the house?  Thanks for your help. 

btw, yes I have two L1 M 2 which we typically use instead of wedges but the towers preclude use for a Pit band set up in front of a stage.  Hence, the wedges.

Hi Rotnick,

Thanks for all the background information. That's really helpful.

The problem is that the signal the house received was so hot that we had to back off the main output so much that we lost almost all head room for the output to out wedges.  

The T8S XLR outputs are LINE LEVEL. If the house system XLR inputs are MIC LEVEL, the signal will be too hot. You've several ways to resolve the mismatch.

Preferred approaches

  • Most house system mixers should have one of the three options below. On the house system:
    1. Use the MIC/LINE or ATTENUATION switch to lower the input sensitivity
    2. Use the input trim and lower the input sensitivity
    3. Use the 1/4 inch (6.3 mm) Tip-Ring-Sleeve LINE LEVEL input use the T8S 1/4 Tip-Ring-Sleeve output. 
  • Use a -20 dB attenuator pad to between the T8S and the house system

Workarounds (less preferable)

  • On the T8S use the channel pan controls to direct more of the signal to the LEFT (two wedges)
  • On the two wedges, turn up the input sensitivity to match the input sensitivity of the house system. Then you can lower the T8S main output

Is there a way we can separate and create two  "master outputs"

Short answer: No - you can't control the LEFT and RIGHT outputs independently. 

Longer answer: You can control the respective levels of the LEFT and RIGHT outputs by using the individual channel pan controls. This one of the less preferable workarounds above.

without creating another auxiliary mix that may or may not match what we send to the house?  Thanks for your help. 

The Aux outputs are engineered for situations like yours. They to allow you to create and control a separate mix for a separate sound system.

The most conventional approach to connecting the T8S to two separate loudspeaker systems (house system, monitor system) is:

  • Create the house mix sent to the T8S main outputs (XLR or 1/4 inch (6.3 mm) Tip-Ring-Sleeve) gain staged properly to match the input sensitivity of the house system
  • Create an Aux mix sent to the T8S Aux output(s) for the monitors for the band (wedge speakers)


Note: The Aux mix can be set up to be identical to the main mix:

  • Set the Tap Point to POST
  • Set all the AUX LEVELs the same for all channels

Does that help?

Not having used the TM8 this should be verified but what you can do with most mixers, if I needed to use the mains the way you set it up, one can pan the mains left or right to control the relative volume on each output.

It may be better to use one or more of the aux outputs instead. That is the way monitors are usually routed from a mixer.

Good luck!
