Serious power and excellent fidelity in a fully functional mini PA system that doubles as a mic-stand mountable personal monitor.

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

We use 5 of these for on-stage personal monitors...Each performer can get a custom mix from the monitor mixer. Unfortunately, you cannot eliminate the "main mix" input from the "thru" connector, so it's useless as a direct box when sending a monitor mix from the board. The workaround is to patch instrument inputs into channel 1 for "more me" from the DI boxes. A simple toggle switch to include/exclude the main input from thru connector would eliminate the need to run separate DI boxes for acoustic or instrument sources. Also, the mic stand adapter is pressure fitted into the bottom of the plastic cabinet and the boom adapter (on top) is off axis, so the mic tends to pivot or fall. When it's cranked tight, it's difficult to adjust, so the performers tend to hold the monitor and muscle the boom into position. Within a week, the female thread mount on the cabinet failed and came loose. We were able to epoxy the part back into place, but this is not the quality of design I would have expected from Mackie. It's a great monitor, but there's still some room for improvement.

This is one of the best "spot" monitors you can get. The built-in Tapco-quality mixer is flexible. It can interface with bigger portable speakers or other gear easily. That's the good stuff...It is overpriced. We have had to repair a number of these now, so I know what's inside. It uses a premium Neodymium driver, true, ?but as good as it is, the frequency response is only for vocals and light acoustic guitar. As soon as you try putting keyboards, distorted electric guitar or anything else through it at volume, it will compress and thermal off. Worse, it could die.So if you use it as it was intended, it is Fine.Traveling business-speakers who address small groups at trade shows will love this thing. Anyone else with little or no technical knowledge and modest audio requirements, will believe it is OK.Those people can't possibly know how cheap this is to make or why it works well for those applications. It is a simple law of acoustics? any sound source is LOUDER when you are very close to it. Sound volume dissipates rapidly with distance. THAT is the only reason small ?spot? monitors like these work. It does NOT require advanced technology or even premium components to accomplish. Further, there is a HUGE problem with spot monitors if you attach them to your mic stand. Sure, the speaker is facing you, directly behind or below the microphone. That would normally be a good position to prevent feedback because most vocal microphones have their greatest rejection from behind. That is NOT true if the speaker is mechanically coupled to the same stand that the mic is on! The stand, the floor, the stage, the plastic box, all have their own resonant frequencies. No wonder this thing causes anomalous feedback modes!And none of us who work on these things think it is worth the price. Even with modest technical background, you can buy similar components and assemble a mini-monitor for vocals that shames this venerable company's name. Mackie makes some great gear... But they are really overcharging for Neodymium, which is NOT rare and should NOT be expensive. Convenience has its price. In this case, the price seems like profiteering.

Read the horror stories- Don't buy this

By Bean

from Bristol UK


  • Good while it lasts


  • Thermal Fuse

Best Uses

    OK- this was good for over a year- although very little use.
    Today it cut out- why? couldn't work it out....
    ..until I went on line and googled SRM 150 power loss and read all the comments. It appears there is a thermal fuse that just decides to cut out. Can this be replaced? repaired? I don't know yet. Suffice to say I wish I had read the bad comments before purchase. This is something that apears to happen a lot and renders the speaker USELESS. Take my advice DON'T BUY

    Unreliable - Do Not Buy

    By steve gifford

    from Kent, UK

    Would nice if these actually worked!
    I'm a drummer and use the SRM150 for my vocal feed and a click metrognome.
    The first one failed after just over 12 months and was replaced under warranty.
    The unit had a thermal fuse problem which meant it continually failing when in use.
    Very unhelpful on stage mid-performance.
    Now after around eight weeks the new replacement unit failed with the same issue.
    Power light stays on but can get no sound out of it no matter which input is used.
    So I have completely lost faith in this product as it's unreliable.
    Full refund being sought and other options bieng considered, possible In Ear Mnoitors!
    Looks the part and has all the right controls but ...........
    Over priced but its Mackie so should be quality equipment?


    Unreliable and design flaws

    By Percy Marshall

    from Edmonton, Canada

    Due to the unit failing electronically after only a few months of very proper use as well as the poor design of the boom attachment I would not recommend this unit. It's too bad because aside from those issues (which are quite major) I loved the unit and it's idea.
    The features on this item were great - volume control of send to the 'mains', volume control for the speaker output, 3 EQ controls, 2 xlr/phono combination input channels with separate volume out controls and 1 RCA input channel. All accessed conveniently from front panel. Mic 'thru' input on the back to send output to PA, line/mic sensitivity switch, instrument/mic channel switch. All easy to use and understand. Only feature that failed miserably is the provided mic boom adaptor. It's design is very flimsy and mechanically very weak for it's intention. The weight of a mic stand boom with a mic on it is far too much for the design of the adaptor and therefore the attached boom tends to swing loose. It is almost impossible to tighten properly so it doesn't swing because the locking washers get stripped too easily. The base of the adaptor gets stripped almost instantly.
    On the quality side when this item worked correctly I found the sound quality to be great. The item 'seemed' to be well constructed and heavy duty with the exception of the boom mic stand attachment. The EQ controls were very useful and the overall quality of the vocal sound for a monitor was more than adequate. I did not use the unit on stage for anything but a 'more me' vocal monitor and it was used in conjuntion with powered floor monitors. It gave me the ability to get bring my own vocal to the forefront for myself.
    The second channel on my unit completely failed after a few months of use and the other channel is now intermittently cutting out. I have positively ruled out my mic and the cable as the souce of the problem and it is definitley in the unit itself. I did not expect this to happen to a product from Mackie.

    The first one had a burnt fuse, then I bought a 2nd one and use them as my stage monitors for my tenor sax (Sennheiser 908B clip mic + Behringer1002 mixer + wah pedal), in both my Blues 5tet and Sax/Organ/Dr Jazz trio, for 3 years now, 8 gigs/month, no problems at all. No big bass range response, but it's a close range monitor, with a 5.25' speaker, there's no miracles! They work fine, for the sax.


    Not Durable

    By JBudge3705

    from Maine

    I bought this unit for use as a vocal monitor for my band's drummer. Bad idea! The speaker blew on the second gig. I thought we'd plug in some headphones for him to continue using it temporarily. With all the connections on this you might expect a headphone jack but there is none to be had. I paid for Mackie quality and I'm left extremely disappointed by this unit. I called customer service this afternoon to see about repairing or replacing the speaker but they are only open in the AM. From previous comments I don't expect much gratification.


    Worked fine until it broke... twice

    By Joe-ZJ_DB

    from New York

    The Mackie SRM150 was recommended to me at Guitar Center, and sounded good enough in the store. The extra inputs in front, plus the choice of XLR or 1/4" inputs were nice, and the sound quality was enough to suit my band's needs. Unfortunately, less than two months after buying, it died on stage. I figured out during the set break that if I jiggled the fuse case it might turn back on for a few minutes, but that was the best I could get from it.So I contacted Mackie since it was under warranty. Several weeks later I got a response, and was sent a replacement with a box to ship back the old one. For a few months, I was satisfied.Then the front grill came off. Not too bad, and I fixed it with a little glue, but this shouldn't have happened.Then, a month after that, the speaker died on me mid song. Completely silent. I couldn't get sound from any input, and I had to finish the gig and play the next gig with no monitor.This time, support was even less supportive. A week after contacting them, I was told that I'd have to take the item to a service center, with the closest one being about 90 miles away. Apparently, some people were cranking the volume too high and getting replacements, so now I'm punished for their mistakes. The person I spoke with on the phone even said that he didn't believe I didn't blow the speaker myself. I'm amazed that this model would die on me twice. Once was bad, but forgivable is the support is there. Twice (not counting the speaker grill falling off), plus the bad support, is enough to keep me away from Mackie for the rest of my career.


    Nice concept but poor execution

    By Paj

    from Suburban Philly

    Ask me a question

    CONS: The first one I purchased failed (Master at 1/2, Channel at 1/3, EQ flat) after six days---no sound and the pilot light started cycling from dim to bright, sending a corresponding noise to other equipment plugged into the the same AC outlet. The second unit had front-panel channels fail. Frighteningly unreliable. The boom-stand extension connector is a joke.PROS: Really nice features and volume in an amazingly compact package. A passthru/mix selector for the rear (fourth!) input and an 8-inch speaker version would make the thing really nice. Oh, yeah, take the fear out of using on a gig and MAKE THE THING RELIABLE.


    Great Mini-PA/Powered Monitor

    By Smith1279

    from Arizona

    I have used the SRM150 for several months as a direct microphone "hot spot" and as a powered monitor. I used Crate powered "hot spots" for many years, but this unit beats them hands down (Crate doesn't even make them anymore). I bought the "scratch 'n' dent" and can't see where there are any flaws. The only thing that I think was left out of the design is an ouput for headphones that cuts the speaker off. This ability would greatly enhance its stage versatility.


    great features but not reliable

    By Anonymous

    from Undisclosed

    Our R&B group use the SRM 150s for vocal and horn monitors on stage. Near field concept is great, cutting down on stage volumn. As designed,it does this well. However, upon arrival, a power indicator did'nt work, and now one unit shuts down at even low volumn levels like it is thermaling. We are not over loading it on the inputs, and my personal levels are master at 12 o'clock and channel at 10. A great idea isn't worth much if it is undependable. If you play live, your gear can not let you down. The SRM150 has let me down badly.


    It dies at sound check!

    By UkeLadyMusic

    from Dallas, TX

    I only had the unit for a week and played a one hour acoustic gig on Friday ... only used one mic. The next day I took it to an open mic and got no sound. Power was on but nothing happened. The unit was replaced with no problem but I have not tried the new one. I'm leery about depending on it at gigs after reading about so many similar issues with it dying.
