RBH Sound PC-10 SUBWOOFER - Manual (Page 5)

1. Volume Control: The volume control should be at the
minimum setting (all the way counter clockwise) before
plugging the subwoofer into a 120V AC wall socket.
2. Crossover Frequency Control: The variable
crossover frequency control allows you to set the
crossover point of the subwoofer anywhere from
50-150 Hz. This control is only active with use
of the left and right line level inputs (#5). If using
these inputs experiment with setting the crossover
frequency control at highest setting initially.
Increasing the crossover frequency will allow more
mid-bass output from the subwoofer. Decreasing
the frequency will cut more mid-bass output from
the subwoofer.
3. Phase Control: This control changes the phase
of the subwoofer. Changing the phase will change
the way the subwoofer and main speakers interact
with each other at the crossover frequency. Varying
the phase position may result in more or less mid-
bass depending on the phasing between the main
speakers and the subwoofer. Generally, the phase
is left at the 0° position.
4. LFE Line Level Input: Typically this will be the
line level input used to connect to most receivers
or processors. The LFE input will bypass the
subwoofers crossover control, rendering it non-
functioning. This input should be used when the
input signal is coming from a receiver or processor
where the bass management is controlled by the
receiver or processor.
5. L/R Line Level Input: If a full-range signal is being
sent from the receiver or processor then these inputs should be used. In this
configuration the crossover frequency (#2) is active.
6. High Level Input: These binding post terminal connectors are for the amplifier/
speaker level input from an amplifier or receiver. Usually, the LFE line level input
(#4) will be used. Important! Use either the Line Input or the High Level Input.
DO NOT use them both simultaneously.
7. High Level/Speaker Output: This is a 100 Hz high pass crossover for your
satellite/main speakers. The crossover limits the low frequencies (below 100 Hz)
from going to your satellite/main speakers. You may use this crossover only when
using the High Level Input terminals. Connect your main speakers (observing the
proper polarity) to the terminals labeled “High Level Out”.
