Owner's Manual High-Performance Subwoofer Amplifiers SA-200, SA-400
The following list describes the rear panel of the amplifier and control functions (refer to fig. 2 on previous page).
These RCA type terminals are for the pre-amp level input signals coming from a processor or
preamplifier.
Important! Use either the Line Level inputs or the “Speaker Level” inputs separately. DO NOT use both, as
damage to the receiver and/or the Subwoofer Amplifier may result.
Warning! DO NOT connect an amplified or speaker-level signal into these inputs.
These RCA type terminals carry the same signal that goes into the line inputs. These terminals
are used if an output signal is needed elsewhere in your system. These outputs are full-range outputs.
These 100Hz high-pass speaker outputs are for your satellite/main speakers. The
built-in crossover limits the frequencies below 100Hz from being sent to your satellite/main speakers. You may use
these speaker outputs only when using the “Speaker Level” input terminals (#11). Connect your satellite/main
speakers (observing the proper polarity) to the binding posts labeled “Speaker Level Out.”
Note: These connectors are not powered by the Subwoofer Amplifier.
These connectors are for the amplifier or speaker-level audio output from an amplifier
or receiver.
Important! Use either the Line inputs or the “Speaker Level” inputs separately. DO NOT use both, as damage to
the receiver and/or the Subwoofer Amplifier may result.
This is the amplified audio output of the Subwoofer Amplifier. If the Crossover Switch
(#5) is in the “on” position, the audio output will be limited to the lower frequencies selected by the Frequency
Control (#6). If the Crossover Switch (#5) is in the “off” position, the audio output will be full-range. An impedance
load of 4-16 ohms may be connected to this binding post. Please follow the instructions in the connections section
of this owner’s manual for proper wiring information.
This knob adjusts the brightness of the indicator lights on the front panel.
If your model features this capability, this switch allows you to select between
110V A.C. (60Hz) or 220V A.C. (50Hz).
Warning! If the voltage setting does not match the A.C. power supplied, damage to the Subwoofer Amplifier may result.
This is the power fuse access.
Warning! In the event the fuse must be replaced, the replacement fuse must match exactly the original fuse value.
If the replacement fuse is not of the same value, damage to the Subwoofer Amplifier may result.
Caution! Before replacing the fuse, disconnect the power cord from the power receptacle.
