EQM131
The Atlas Sound 1 RU EQM131 is easily connected to any system via rear panel balanced TRS and XLR jacks.
Unbalanced RCA connections are also provided for use with -10 dBV equipment. Front panel mounted Low Pass
Filter / High Pass Filter (LPF / HPF) and level controls are provided along with a switch for ±6 db or ±12 dB opera-
tion as well as 31 sturdy 20 mm filter slide controls. The ISO centered 1 ⁄
3
octave bandwidth-constant Q filter
design minimizes interaction between filters yet is still wide enough for effective correction curves.
When utilized with the Atlas Sound AA120M mixer amplifier and AA-SMG sound masking module, the EQM131
can be used to create a 1 ⁄
3
octave masking spectrum which is fed directly to the AA120M amplifier. Paging or
music inputs can receive high frequency shelving equalization for better intelligibility from the AA120M front panel
controls. The page / music inputs and masking module output can then be summed without affecting the masking
source spectrum equalized by the EQM131.
