AC Select Switch. The input-power voltage is set at the factory to correspond with
the country to which the R-Series studio monitor was shipped. Use this switch only if
you are using your R-Series monitor in a country that uses a different standard
voltage than is used in the country where your purchased your monitor originally.
High Frequency. Boosts or cuts all frequencies above 10 kHz by ±6 dB.
Power User Tip: The High control on the R-Series studio monitors is a high-shelf EQ and
raises or lowers all frequencies above 10 kHz. This EQ is much like the treble control on a
car stereo and likewise can make big changes to the sound very quickly. If you find your
mixes are translating too dark on other speaker systems, try lowering this control. Too
bright? Raise this control a bit. In either case, anomalies in your room may be negatively
impacting your R-Series studio monitors' performance. See Section 3 for set-up and
calibration tips.
Mid Frequency. Boosts or cuts frequencies around 1 kHz by ±6 dB.
Power User Tip: The Mid control is a peak EQ that lets you raise or lower the level of a
two-octave-wide frequency band centered at 1 kHz that can make subtle changes to the
frequency response of your R-Series monitors. In general, you will not want to alter this
control as it will change the flat frequency response of your R-Series monitors. However, if
you would like to quickly emulate the performance of consumer speakers, lowering this
control will mimic the mid-range scoop that is the hallmark of consumer designs.
Low Cutoff. Rolls off the level of all frequencies below the specified frequency (80 or
100 Hz) at a slope of -12 dB / octave. Setting this control to Flat allows the speaker's
natural roll off to take over.
Power User Tip: If you are using a subwoofer that doesn't feature a variable low pass
filter, like the PreSonus Temblor T10 provides, you will use this control to set the crossover
point for your 2.1 system. For information on configuring a 2.1 system in the studio,
