[. . . ] The LOW EQ provides a boost or cut of up 15 dB for the very lowest frequencies, below 100 Hz. These frequencies are represented by the punch in bass drums, bass guitar, and some really serious male singers. 6. MAIN LEVEL This is used to adjust the signal level from the SRM150 mixer, going into the built-in power amplifier. Follow the Quick Start guide on page for setting the MAIN LEVEL control.

POWER Switch Switch up to turn the SRM150 on. Make sure the MAIN LEVEL [6] control is down before you turn it on. Press the bottom of this switch to put the SRM150 into standby mode. It will not function, but the circuits are still live. To remove AC power, either turn off the AC mains supply, or unplug the power cord from the SRM150 and the AC mains supply. When the POWER switch is turned on, and the linecord is connected to an active AC Mains supply, the cool blue LED on the front of the speaker glows to let you know that you're ready to rock and roll. Note: If you happen to lose the AC linecord, replacements are readily available at any office or computer supply store. Always use a three-pin plug with a ground pin. 11. THRU Connector This is a male XLR connector that produces the main signal just prior to the EQ [7] controls and the MAIN LEVEL [6] control. The signal at the THRU connector includes the input signals connected to channels 1- [1/] and the MAIN IN [1] signal. Use this connector to patch the signal from the SRM150 to another SRM150 or other active loudspeaker (like an SRM50 or SRM50), or to a mixer. 9. FUSE This is a resettable circuit breaker that monitors the amount of current being drawn by the SRM150. Under normal operating conditions, this should never pop. An unusual condition may cause the breaker to pop, such as a mains voltage surge occurring at the same time as a peak amplifier output. To reset the breaker: · Turn the POWER [8] switch off and push the FUSE switch to its UP position. · Turn the POWER switch back on and the SRM150 should resume normal operation. If the circuit breaker pops again, there may be something wrong inside the SRM150. Refer to "Repair" on page 15. 12. [. . . ] Make sure the connecting cables are in good repair and securely connected at both ends. Make sure the output volume (gain) control on whatever is connected to the SRM150 is turned up sufficiently to drive the inputs of the speaker. 1 Repair For warranty service, refer to the warranty information on page 19.
