Utilizing The Built In Active Filters - Emotiva RSP-1 User Manual

Utilizing the Built In Active Filters

The RSP-1 contains both high pass and low pass filters to further enhance the applications under which the
RSP-1 preamplifier can perform. Since many modern loudspeakers have become smaller and more "furniture
friendly", they are not always capable of the 20-20kHz full range, high volume output that traditional 3 or
4 way tower speakers are. Likewise, the advent of separate and multiple subwoofers to reinforce the low
frequencies sometimes deficient in more open listening spaces also creates a need for filters on board the
RSP-1 preamplifier.
Both the XLR and RCA full range outputs are 20-
20kHz outputs and are unaffected by the selectable
HP and LP filters. These outputs would commonly be
used if only one main pair of full range of speakers
are connected or if a subwoofer is connected but
principally to reinforce full range speakers.
The high pass section of the RSP-1 is selectable at
80 or 120Hz by the HPF switch. Slopes are 12dB/
octave. This filtering is available on the "HIGH PASS"
outputs, either RCA or XLR.
The low pass section of the RSP-1 is selectable
at 80 or 120Hz by the LPF switch. Slopes are
12dB/octave. This filtering is available on the "SUB
OUTPUT" plug, either RCA or XLR.
