SM-900 Bridge Mode Operation Diagram

Power Amp Assign Switch	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
set to “Bridge Mono” position.
	into an 8 ohm load. Please make sure that your speaker system is capable of handling this amount of power.

Center Bridge/Mono Speakon Output Jack must be used.

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
