SM-900 Bridge Mode Operation Diagram
Power Amp Assign Switch
set to “Bridge Mono” position.
Center Bridge/Mono Speakon
Output Jack must be used.
Note: When the power amp assign switch is set to the Bridge/Mono position, only the center Speakon output
jack may be used. The SM-900 delivers a minimum of 900 Watts RMS into a 4 ohm load, and 650 Watts RMS
into an 8 ohm load. Please make sure that your speaker system is capable of handling this amount of power.
Speaker 1 = 8 Ohms
Speaker 2 = 8 Ohms
This example shows two 8 ohm speaker enclosures connected in parallel for a total load of 4
ohms. This is the minimum impedance that the SM-900 is designed to drive safely in the Bridge
Mode. Connecting multiple enclosures that have a combined total impedance of less
than 4 ohms may result in damage to your amplifier.
The following cabinet configurations may be used:
• one 4 ohm enclosure
• one 8 ohm enclosure
• two 8 ohm enclosures
• four 16 ohm enclosures
