CONNECTIONS
1. Input
Input is made through RCA line level input jacks, Connect the outputs
of the preamplifier, receiver or surround processor to these connectors.
If you are connecting to a single LFE output, you can connect it to either
jack. If you need more sensitivity from the subwoofer/amplifier system,
then connect the LFE signal lead to a Y-adapter cable and connect one
output into each jack.

then connect the LFE signal lead to a Y-adapter cable and connect one

2. Output(s)
Two output connections with 5-way binding post terminals are provided.
Each binding post accepts standard 4mm banana connectors, crimp-on
lugs, pins or twisted bare wire through the post hole under the post nut
covers, and twisted bare wire around the metal post. Each output has a
minimum impedance of 8 Ohms (one B28W or B28C).

3. Low Pass Crossover
The variable 50Hz – 150Hz low-pass crossover determines the frequency
at which the SA1000 blends to the main speakers.
at which the SA1000 blends to the main speakers.
NOTE: This control does not limit the frequency range of the main
speakers in the system. Adjust the Low-Pass Crossover control to
properly blend to the satellite speakers. When the blend is correct,
notes of instruments and voice in the crossover region should sound
correct in level; not too loud relative to the subwoofer frequencies or
satellite frequencies, but also not too soft. When the control is turned to
“LFE” the crossover is by-passed and all crossover settings are now set
in the Processor or AVR menu.

EQUALIZATION
The equalization controls tailor the amplifier’s response for your listening
position in your specific listening room. The parametric equalizer
includes variable controls to adjust Frequency, Bandwidth (or “Q”) and
EQ Level of one band of eq, as shown in Figure 3. To use these controls,
you first must set the EQ switch to “ON”.

6. EQ Level Control
Allows you to adjust how much boost or cut is applied to the selected

to a maximum of +3dB.
7. Phase Switch
Adjusts the phase of the subwoofer’s output to the front speakers.
Proper phase adjustment can also depend on variables such as the
in-wall subwoofer placement and listener position. Set this switch for
maximum mid-bass output at the primary listening position.
