EMP Tek E10s (100Watt) - 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) and speaker level inputs (#6). 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 subwoofer’s crossover
control. 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-passed output for your satellite/main
speakers. The crossover limits the low frequencies (below 100 Hz) from going to your
satellite/main speakers. This crossover is active only when using the High Level Input
terminals. Connect your main speakers (observing the proper polarity) to the terminals
labeled “High Level Out”.
