I have been asked several times how to calibrate the speakers using the TMC-1, you can find the answer buried in the reference manual or read this quick post.
There are two ways of calibrating the inputs and speaker outputs
1) Using the TMC-1
[Select]+[Page] to enter the select page
[Select]+[Setup] to enter Advanced setup
Adv Menu-2 Calibration Lock - select - Unlock All
[Page] to exit Setup
With [Sum] off, hold a input select key depressed you can trim an input -10/+20dB
[Ctrl] to select speaker solo
Hold a speaker key depressed and you can trim the speaker gain +/-4dB
2) Using the TMC-1v6 program
Select the 'Cal" page
Enter the password "1984"
You can the adjust the trim values and save/load them from disk.
Hopefully this will help, but please Email or Call if you have any questions
