PRESONUS Eris E5 BT - Power and Acoustic Tuning Controls

2.1.2 Power
IEC Power Connection. The active speaker accepts a standard IEC C7 power cord. The power switch
is located on the front panel of the active speaker.
2.1.3 Acoustic Tuning Controls
High. Boosts or cuts all frequencies above 10 kHz by ±6 dB.
Power User Tip: The High control is a high-shelf EQ and attenuates or boosts frequencies above 10
kHz. This EQ is much like the treble control on a home or car stereo: It raises or lowers the gain on all
frequencies above the specified cutoff frequency. Shelving EQs can make big changes to the sound
very quickly by adding or removing an entire range of frequencies.
Low. Boosts of cuts frequencies around 100 Hz by ±6 dB.
Power User Tip: The Low control is a low-shelf EQ and attenuates or boosts frequencies below 100
Hz. This function is the equivalent to the Bass control on a home or car stereo: It raises or lowers the
gain on all frequencies below the specified cutoff frequency. Shelving EQs can make big changes to
sound very quickly by adding or removing an entire range of frequencies.
