Precision Power DCX 300.4 - Manual (Page 25)

Your new DCX amplifier has a TC-X Crossover (Total Control X-
over ® ) 30Hz-4kHz (see this guide for Crossover Chart).12dB per
octave phase correlated crossover built-in to provide superior
system flexibility without the added expense and installation of an
outboard crossover. The speaker outputs of your amplifier are high
pass, low pass, or all-pass according to the HP/LP/FULL switch on
the front endplate. You would choose low pass (middle position of
switch) to use this amplifier for subwoofers, choose high pass (left
position of switch), or full (right position of switch) to use this
amplifier for full range speakers.
The RCA outputs are controlled by a separate HP/LP/FULL switch,
and are always independent of the speaker output crossover. As
well as being able to independently select HP/LP/FULL, your new
DCX amplifier allows independent selection of frequencies from
30Hz-4kHz (see Crossover Detent Chart in this guide).
