Protective DSP Settings
The EMS-51 requires no DSP program to function correctly. However, excessive low frequency information will
cause the LF drive unit’s excursion to increase, which can result in damage to your loudspeaker.
The higher you raise the high pass filter on an EMS-51, the more headroom and overall sound pressure level
output there is available. For most medium-to-high level applications, we would recommend a minimum of an
80Hz high pass filter with a 24dB/octave slope to sufficiently protect the loudspeaker. For higher SPL applications,
we would recommend raising this filter – we would stress that the higher the filter, the safer the loudspeaker will
be. If you are in any doubt over suitable settings for your EMS-51, please don’t hesitate to contact EM Acoustics
or your local dealer for support and advice.
