I just have one calibration file (see attachment of my previous post), according to that file my ECM8000 was calibrated in a horizontal position (0 degree incidence). It is pretty flat from 30Hz to 1kHz. >From 1kHz to 10kHz there is a continuous increase up to +2db and from 10kHz to 20kHz there is a drop down to -4db. Compared to the chart in the thread my calibration file resembles the blue curve the most. That's funny because the blue curve is the vertical measurement and my microphone seems to have a similar behavior in the horizontal position... The differences between my ECM8000 and the one measured in the thread might be because of different microphone series (or due to a misunderstanding and my calibration file actually was created in a vertical position). Nevertheless, regarding the question of vertical vs horizontal position, I got constant results with or without calibration file: The horizontal position intensifies the mids while treble is attenuated, leading to a cavernish sound. The vertical position sounds correct. The calibration file is not the reason for the huge differences between different microphone positions. -- Quad Audio Room: Touch -> DacMagic -> Quad 77/707 -> Magneplanar 1.7 Living Room: Duet -> X-DACv3 -> Exposure 3010 S2 -> Rowen Absolute MONO -> Quad 21L Sleeping Room: Radio ------------------------------------------------------------------------ Quad's Profile: http://forums.slimdevices.com/member.php?userid=20234 View this thread: http://forums.slimdevices.com/showthread.php?t=93393 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
