    Distance: 0m ~ 143.139m Polarity The phase of the SP48 inputs can also be altered. Press ENTER to change the setting, and then the polarity of the input can be set to either [Normal] 0˚ phase shift [Invert] 180˚ phase shift...

  • Page 21: Rms Compressor

    RMS Compressor The input channels on the SP48 have an RMS compressor which can be enabled. The compressor reacts to the RMS (Root Mean Squared) level of the signal, this is an average measurement so reaction time and changes will be more gradual than a peak Limiter.

  • Page 22: Eq Bypass

    EQ. 30 Band EQ [EQ-01 -> EQ-30] The SP48 has a 30 band EQ for all four of the input’s channels. These are useful for adjusting the entire systems response, a common use is for acoustical room corrections.
  • Page 23 Note: [Low-Pass 1,2,Q], [High-Pass 1,2,Q] , [Notch Filt] and [All Pass 1,2], the gain is fixed. [Q] The PM3 control changes the Q factor of the EQ. For filters with a 1 or 2 in the title bar [All Pass 2], the Q factor is fixed by the preset. When the type is set to [Peaking_Eq] the Q factor controls the bandwidth of the peaking eq.
