Channels 1 and 2 can be used for mic/line sources, the handy Neutrik Combo jack, which accepts either 1/4" TRS or XLR connections.

DEDICATED STEREO INPUTS Channel 3 is reserved for stereo devices, like an MP3, CD or tape player. Connect to the dual RCA jacks from your device and use the Channel 3 Level control to balance the gain with your other inputs. This is a truly needed feature for performers working with backing tracks, MIDI sequencers or drum machines. GLORIOUS MACKIE 3-BAND EQ We invested tremendous resources optimizing the center frequencies of our 3-band active EQs. By selecting 100Hz, 2.5kHz and 12kHz, for the Lows, Mids and Highs, respectively, we created an equalization scheme of a highly musical nature. And SRM150's EQ bands work very independently of each other, allowing you to cut or boost a specific band without affecting the others. With up to 15dB boost/cut capability per band, the onboard active EQ provides more tone-sculpting latitude and feedback control than you'll find in any other product in its class. HIGH OUTPUT, PREMIUM QUALITY SOUND All the "bells and whistles" in the world are completely worthless if you can't crank out world class sound! That's why we matched the SRM150's powerful 150-watt Class-D amplifier with an equally impressive 5.25" full range, weather-resistant neodymium driver, which was developed by the speaker gurus at EAW. The SRM150 puts out a blistering 120dB SPL @ 1 meter, far more than the competition offers. And the SRM150 sounds great, whether you're accompanying a vocalist with your acoustic at the coffee house or making an A/V presentation to the board of directors. THE ULTIMATE PERSONAL MONITOR Not only is the SRM150 an excellent loudspeaker system for compact PA applications, but it also offers unparalleled performance as a personal monitor. The onboard 3-band EQ facilitates feedback suppression and offers the same great tone-shaping capabilities as our legendary compact mixers. Mic stand ready with an included boom arm adapter, the SRM150 puts total control right at your fingertips. In addition to stand mounting, the SRM150 was designed to provide the proper monitoring angle when used in traditional floor wedge and tabletop placement. Let's face it, putting high output, quality sound right where you want it is what monitors are all about! REAR PATCHBAY Want to use a second SRM150 or an SRM450? The rear panel Thru jack provides connectivity for an extra powered monitor, or for sending a mic level output to the front of house system( by activating the mic/line switch. The Main input also has a dual purpose. It can obviously be used to receive monitor mixer signals, but can also be used to link more SRMs.
