[. . . ] Check the manual for your microphone to find out for sure whether or not phantom power can damage it. 7. HIGH, MID, and LOW EQ Use the EQ controls to make overall adjustments to the sound of the SRM150. The HIGH EQ provides a boost or cut of up to 15 dB for the very high frequencies, above 1 kHz. These frequencies include the sizzle of cymbals, the edge of a guitar, or the upper harmonics of vocals. In general, boosting the HIGH EQ will brighten the sound of the loudspeaker. The MID EQ provides a boost or cut of up to 15 dB for the mid-range frequencies around . 5 kHz. Most vocals are located in the mid-range frequencies, so this can be used to bring the vocals up or down in the mix. 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.

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. 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. 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. [. . . ] · Is the input gain control [] or the MAIN LEVEL [6] control turned all the way down?Follow the procedures in the "Quick Start" section on page to verify that all the volume controls in the system are properly adjusted. 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.
