Not sure what the range is, but I'll post pay ranges for terminal training (OKC), Front Line Manager/Supervisor (LV Tower - lvl7) and front Line Manager (ZAU - lvl12)
Air Traffic Control Specialist (Terminal-Instructor) From 91,781.00 to 119,314.00 USD per year
Supervisory Air Traffic Control Specialist Operations Supervisor (Front Line Manager) From 136,119.00 to 172,200.00 USD per year
Front Line Manager(ZAU ARTCC) From 155,530.00 to 172,200.00 USD per year
It looks like the salaries vary quite a bit and are dependant on the facility level just like an ATC. I can't tell from the postings though if locality is or is not included in those ranges.
You can go check the job postings on faa.gov and choose 'I am a Fedaral Employee" then I just typed in Traffic Manager in the search field.
