Lend Me Your Ears Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in this chart.
REAR PANEL DESCRIPTION POWER Switch Use this switch to turn the SWA1801 on and off. Make sure the signal source’s level control is turned down before you turn it on. AC power supply, this indicator lights green to let you know that you’re ready to rock and roll. The cool blue LED on the front of the cabinet works in the same way. FULL RANGE INPUT AC Receptacle This is where you connect the AC linecord to provide AC power to the SWA1801’s built-in power amplifiers.

CONNECTIONS The SWA1801 has two female XLR inputs that accept a balanced line-level signal. When connecting a balanced signal, be sure it’s wired per AES (Audio Engineering Society) standards: XLR Hot (+) Pin 2 Cold (–) Pin 3 Shield (Ground) Pin 1 The THRU output connectors allow you to connect more than one SWA1801 to your system. Simply plug the signal source (i.e.
AC POWER Be sure the SWA1801 is plugged into an outlet that is able to supply the correct voltage specified for your model. If the voltage should drop below 97% of the specified line voltage, the built-in amplifiers will no longer be able to supply rated power. (They will continue to operate down to 80% of the rated line voltage, but won’t reach full power, resulting in lower headroom.) Be sure the electrical service can supply enough amperage for all the components connected to it.
No sound Noise • Is the input LEVEL control for the input source or the subwoofer turned all the way down? Verify that all the volume controls in the system are properly adjusted. • Is the signal source working (and making union scale)? Make sure the connecting cables are in good repair and securely connected at both ends. Make sure the output volume (gain) control on the mixing console is turned up sufficiently to drive the inputs of the speaker.
