14 OPERATING PRECAUTIONS FOR THE SLS918
The SLS918 is essentially an SLS915 combined with an SBS12 subwoofer into one enclosure. When
used in PASSIVE mode it has similar performance to an SLS915/SBS12 combination but does not
require an electronic crossover.
It is important to note that the PowerSense DDP protection circuit for the SLS918 LF driver is bypassed
in BIAMPLIFIED mode. When using an electronic controller in this mode electronic protection is
provided by the controller. If these controllers are not used, it is recommended that an external limiter
be used to provide electronic protection to help prevent possible damage from excess power. Set the
limiter to provide at least a 10:1 compression ratio and set its threshold to below amplifier clipping.
The amplifier power output rating should be within the range recommended in SECTION 9.1.2
