SM-500 Stereo Mode Operation Diagram
Power Amp Assign Switch
set to “Stereo” position.
Note: When the power amp assign switch is set to the “Stereo” position, only the right and left Speakon
output jacks or left and right 1/4” output jacks may be used. Do not use the center Speakon jack as it is
provided for Bridge/Mono operation only.
SM-500 Power Output Ratings
Stereo Mode (per side)
300 watts @ 2 Ohms
250 watts @ 4 Ohms
150 watts @ 8 Ohms
(minimum load = 2 Ohms)
Speaker 1 = 8 Ohms
This example shows two 8 ohm speaker enclosures, each connected
to one side of the stereo power amp for a total load of 8 ohms per
side. Although the minimum impedance that the SM-500 is designed
to drive safely in the Stereo Mode is 2 ohms (per side), 4 ohms per
side or greater is recommended. Connecting multiple enclosures that
have a combined total impedance of less than 2 ohms per side may
result in damage to your amplifier.
The following cabinet configurations can be used:
• one 2 ohm enclosure (per side)
• one 4 ohm enclosure (per side)
• one 8 ohm enclosure (per side)
• two 4 ohm enclosures (per side)
• two 8 ohm enclosures (per side)
Speaker 2 = 8 Ohms
