Before making any connections, ensure that power cord is disconnected
or that the main power switch is switched to the off position.
Output Connections:
There are two sets of outputs on the back of the amplifier. Since this is a mono amplifier the exact same signal
is present at both sets of outputs. Outputs 1 and 2 are internally connected in parallel. Therefore, calculating
the load impedance for the two connections should be done as it would for any parallel connection. For example,
connecting an 8-ohm load to Output 1 and a second 8-ohm load to Output 2 would produce a 4-ohm load for the
amplifier. Note: The Model 500 is optimized for a 4-ohm load.
The Speaker output connectors are 5-way binding posts. They will accept banana style plugs. To access the
banana connections, remove the black and red button-plugs from the back of the connectors by pulling rearward
on the plugs.
No signal connection cable is provided with the MODEL 500 amplifier since the length of cable is installation
specific. A shielded RCA type coaxial cable or a shielded two-conductor wire with RCA type connectors is
required for connection of the MODEL 500 to the audio system.
Input Connections:
Follow the diagram on page 7 for connecting the subwoofer to your audio system. Use the option that best suits
your installation. The information below will aid in determining which option to use.
OPTION 1
(Left - Right Stereo)
If an LFE (Low Frequency Effect) or Subwoofer output is available then skip to Option 2 since it will likely
produce the best results. If no LFE output is available and a line level Front Channel Output or Preamplifier
Output is available, then this (Option 1) is the preferred method of connection.
Per the Option 1 drawing on the adjacent page, use a stereo RCA style (patch) cable and connect the left and
right line level (RCA style) front channel outputs of your receiver or preamplifier/processor to the Left/Right Line
Level inputs of the MODEL 500.
OPTION 2
(LFE)
If the amplifier is to be connected to a modern home theater receiver or processor with an available LFE or
Subwoofer output then this option will likely produce the best results. If no LFE or Subwoofer output is available
but a line level Front Channel Output or Preamplifier Output is available, then use Option 1.
Per the Option 2 drawing on the adjacent page, use a single RCA style (patch) cable and connect the
line level (RCA style) LFE or Subwoofer output of your receiver or preamplifier/processor to the Left/LFE
Line Level input of the MODEL 500.
AC Power Connection:
The unit is shipped with a standard IEC AC cable. Remove this cable from its packaging and insert the cord into
the IEC receptacle
11
on the back of the amplifier. It is best to connect power only after all other connections
are made. Connect the power cord to an AC wall receptacle or similar source.
