The SRM150 combines Mackie's proven mixer and SRM active loudspeaker technologies to create a powerful, great-sounding 3-channel PA system that is ultra-compact, versatile, and expandable. The Mackie SRM150 Compact Active PA System is ideal for a wide variety of applications ranging from boardroom A/V to live musical performance in small venues.

Don't be fooled by the small size. The SRM150 PA System is big on features and sound quality. The built-in three-channel mixer features two combo XLR/line inputs (with true 48V phantom power), a stereo channel for CD/MP3 players, and Mackie's powerful 3-band Active EQ. The SRM150 can even be mounted on a mic stand, making it the ideal personal monitor. Put simply, with its tremendous feature set and 150-watts of world-class sound, the Mackie SRM150 is the perfect solution for any application requiring superior sound quality.

Built-in Mackie mixer
At the very heart of the SRM150 is a Mackie mixer, with all the versatility and features you've come to expect from the manufacturer of the world's best selling compact audio mixers. Channels 1 and 2 can be used for mic/line sources, thanks to the handy Neutrik Combo jack, which accepts either 1/4" TRS or XLR connections. True 48V phantom power is supplied, so you can use even the most finicky condenser mics with confidence.

Channel 1 also has an added feature. Simply plug in your guitar, bass (or any other Hi-Z instrument), press the CH1 Instrument switch and you get all the benefits of a DI box, without the hassle and added expense.

Dedicated Stereo Inputs
Channel 3 is reserved for stereo devices, such as an MP3, CD or tape player. Just 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 handy 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 PA system 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.

Applications galore
Uses for the SRM150 are virtually limitless. Below is a short list of some obvious, as well as not-so-obvious applications.

¢Executive boardrooms
¢A/V presentations
¢Tradeshow demonstration booths
¢Classroom instruction
¢Aerobics instructors
¢Live music performance monitors
¢Personal practice with stereo tracks
¢PA system expansion for "Cry" or "Green" rooms
¢Recording studio playback to remote rooms
¢Anywhere high quality audio is required but space is limited

Designed as a personal monitor, not a PA speaker

By Pat Mann

from Northern Virginia

5 stars for compactness, easy-to-use, being a one-piece PA system as the name implies BUT physical design is for use as a personal monitor only. We purchased this system as a compact simple emergency backup PA when on-site sound reinforcement systems are not available or fail at community meetings. Audience typically 50-100 people, occasionally more, in school multi-purpose room or auditorium. Meets our minimum needs to mix 1 wired and 1 wireless microphone, very compact system with minimal cables except to mics, usable by non-expert, loud enough and clear enough to do the minimum job, designed to wire 2 together to give better coverage. However - Physical design points speaker up about 25 degrees toward the ceiling when mounted on mic stand instead of directly out to audience, at an even steeper angle than when set on its base. Support says this is OK, dispersion should be enough to get highs to nearby folks BUT to me it's not ideal. Mounting upside down on upper thread gives correct angle, but cables then hang across mixer controls, support says could void warranty. Mounting on mic stand boom arm can correct the angle at the expense of stability of the mount and more things in the way of people walking by, more likely to be knocked over. Having controls in back instead of front would also improve convenience as PA speaker at expense of convenience as a personal monitor.

from Murrieta, CA

Initially, the Mackie SRM150 seemed to be the right choice. My band is fairly loud and it cut through the mix. A stage mishap knocked it over (easily, because it is too heavy to be stable on a mic stand) and it stopped working. I tracked own an authorized repair center and for another $125.00 it was repaired...sort of. Worked great for about a month. I have noticed this model is being discontinued and I now know why.
