Atrium / Headphone EQ / ETA
ETA EQ settings
Parametric EQ corrections for 3 ETA models, each derived from its measured frequency response. Pick a model for the full filter table, the curve, and how it compares with its siblings.
The ETA house sound, by the numbers
Across the 3 measured models, the most common tuning is dark (3 of 3, 100 percent).
The model that needs the least correction is the Mini Semi-Closed, with no band more than 2.7 dB from neutral. The one that needs the most is the O2, off by up to 4.2 dB before EQ.
