QUESTIONS & ANSWERS

By jonathan langbein from wall, nj on May 2, 2012
how do I hook up my satellite speakers to this amp. doesn't this get hooked up after the receiver and before the pair of satellites so it cuts off the low frequencies to the satellites?
By Customer Service - Q&A on May 3, 2012

Answer:
Hi Jonathan:

The SMP60 does not connect directly to the Satellite speakers. Checkout the SMP250 Sub-0woofer amplifier which features speaker level outputs for the satellite speakers. What Sub-woofer are you planning to use and can you describe the Receiver and satellite speakers you are planning to use?

HI,
Does this amp go with your Sub 200 Omni Subwoofer speaker? Does this amp need to be kept in dry area even though it's powering an outdoor speaker?

Do you have amps that can be located outdoors like your outdoor speakers which can handle all weather conditions?

How would this Sub 200 woofer go with your S450 Omni Speakers? would this make a good sound combination ? Or would it have a weak mid range? Would the bass be too strong?

I'm trying to find a speaker system that suits my situation which has two general purposes:
1. Playing music around a very large balcony area which we've had landscaped with trees, decking, hedges etc. thus the music will be for parties and general easy listening at other times
2. Audio for outdoor video screen to watch movies in outdoor lounge area

So I can see how the Omni directional speakers positioned around the circumference of the balcony in the planter boxes would work well for the music. But would these speakers work well for when we want to play movies using our Apple tv plugged into a video projector projecting the image onto a movie wall located next to the spa being at the opposite end of ten balcony from where we'd sit watching movies from the lounge?

I hope you can make sense of the questions given you haven't seen the layout etc I'm trying to describe

I'm in Sydney Australia. Do you have a distributor of your products here that I can talk to or even go see them? If not does it make it too expensive to order your products online and have it shipped over?

Cheers
Steveya

Answer:
Steve,
The SMP60 is a smaller sub amp. Idealy the SMP250 sub amp would be a better match with the Sub200 omni - It would power your speaker to its full potential being a great addition to the OS450's. Although both amplifiers are strictly indoor, we do not have an outdoor sub amp at this time.

I have a 10 inch sub with these specs
10" Rubber Surround Driver with 22-200 Hz Range
75 Watts RMS and 150 Watts Max
92 db Sensitivity

Will this amp work with this sub?
By Customer Service - Q&A on January 28, 2013

Answer:
Hi Ryan,

It might be a little under powered for your setup. Are you using this for Home Theater or just for music? If it is for Home Theater you should check out our SMP250 and consider adding a second 10 Inch sub to have dual subs for your system. Most better AV receivers now feature 7.2 or dual subwoofer outputs. You would only need a single sub output to connect to the SMP250 than connect both subs in parallel. It would probably be best if you used two identical sub-woofers. Good luck

My input source is a mono pre-amp out from a receiver, so only a single jack. I noticed the back panel has two input jacks. Does this work well with that kind of input source? How should it be connected?
By Customer Service - Q&A on July 6, 2012

Answer:
Hi Nils,
You can use a Y adapter or its common that a single sub cable will work. You would connect that to your one output to either the right or left of the smp60 input. You might find both right and left work or one or the other will only work. This should be no problem.

By Brent from Houston, TX on January 17, 2012
the line out of my current reciever is a single rca, this sub amp has a left and right input, do i need to split the signal or just go to one, or do i convert it to 3.5 mini and go to the stero jack input?
By Customer Service - Q&A on January 17, 2012

Answer:
Brent,
No need to convert, output is a mono signal from your Receiver so just connect to either right or left input of SMP60. Try both, one may sound louder than the other so pick that one.

By Jim Oestreich from Warrington, PA 18976 on November 30, 2012
I have an earlier unit (no auto switch) hooked to an Onkyo HT-RC430 and outputting to an 8 inch 4 ohm woofer. I keep getting a fade of the sound coming from the speaker and the a sudden pop and the sound comes back. Can you tell me what I need to look at as the source of this issue?
By Customer Service - Q&A on November 30, 2012

Answer:
Hi Jim,

The problem may exist in the application. The SMP60 subwoofer amplifier is price-driven product limited to driving a single 8 ohm speaker. If you’re powering a 4-ohm driver, the amplifier has to double its output. Music can be very dynamic with the impedance changing constantly both up and down. Connecting a 4-ohm driver is over-driving the amplifier and causing it to become unstable. The auto sensing feature of the new version would not make a difference in your setup. I would recommend sending the amplifier back to us to be tested. If you still want to use this amp, you may need to change to an 8-ohm in-wall subwoofer like our IWS8. The other option is to upgrade your subwoofer amplifier to our SMP250 to drive your 4-ohm subwoofer. You might even consider adding one of our powered subwoofers like the S-10 or S-12 instead.

I have this Amp, connected to the 8" in wall subwoofer. Every few minutes I get a quick popping noise. Any idea what the problem is?
By Customer Service - Q&A on February 20, 2012

Answer:
Hi Chris:

On the new units we add a auto or music sensing featurer. Check to see what your turn on option are set at. If you have it set to auto-on, first try switching to manual on. Or in the auto-on mode try increasing the volume from your source. Please let us know what you find out.

By Erik from Pflugerville, TX on December 29, 2012
I have the SMP60 + ISW8 combo installed now and I'm not sure I'm hooking it up right. The power auto switches off within a second of pressing the on switch. My receiver is an Onkyo HT-R520 with a single pre-amp subwoofer out. I've tired multiple hook up options, to both the left and the right inputs, Auto vs On position on the switch. The mono amp keeps turning off. I've even disconnected the sub out thinking that end my be causing some overload, but I get the same effect. Is the mono sub working properly?
2nd question, assuming above is rectified, what volume level and cross over frequency should the mono amp be set to? If I crank up the volume to its fullest, can I still control the overall volume for the system off my Onkyo AV amp like I did with my previous powered amp?
By Customer Service - Q&A on December 31, 2012

Answer:
HI Erik,

Whether you select normal or auto, the front on/off button must be in the on position (pushed in). The auto on takes about five minutes before it turns off but comes on almost instantly once a signal is present. If it is turning off after you enable the on switch, then you may have a defective amp. Please call us and ask for Mike the Tech-man. He can determine the problem over the phone.

Works for the purpose intended.
October 28, 2016
Passive subwoofers are rare these days. Almost all have their own built-in amplifiers. However, I bought the SMP60 to fire up a Boston Acoustics A40 that I had lying around and hopefully beef up the low end from my Klipsch KSB 1.1 bookshelf speakers. I listen to mainly to jazz, so in this scenario the SMP60 works fine. BTW, I use the “Tape Out” connection on my old Sansui to feed the SMP60.
Pros:
Used as recommended and connected to the proper driver it extends the low end of small bookshelf speakers.
Cons:
Loud pop when turned on. A little house of blue lights. Yikes!

Works good

Have two of these connected to a 7.2 surround sound system. Doesn't have tremendous bass of course with how low the watts/rms is, but works great and as expected.
Pros:
Not too pricey compared to other low watt amps.
Cons:
Low bass

Good purchase
April 8, 2013
The price was excellent for a nice amp. I'm using it to drive a single 15-inch, 8 ohm subwoofer in an older home stereo system. It has plently of power. I only have to turn it up about halfway to get great full bodied bass.
Pros:
The power for the price.
Cons:
I have to run it on a tape output, so it is not controlled by the main volume of my stereo. This is only a convenience issue. I tend to keep the stereo volume at the same level most of the time.

A small but powerful Sub Amp
March 30, 2013
I was very pleased after connecting the SMP-60 to my Sub Woofer. This Amp replaced a 100 watt amp, and it saved me from discarding the subwoofer that has 2 10" woofers. I am very please with the sound and controls it offers.
Pros:
It is a powerful amp for 60 watts.

With my new dual voice coil in wall subwoofer this amp works great. I was disappointed that there is no remote control. Have to manually turn it off in system with all other components linking to one remote. I have been building speaker enclosures since 1967.
Pros:
Easy To Set Up, Accurate Controls, Good Power Output
Cons:
No remote control
Best Uses:
Basic Systems

Excellent little amp
November 7, 2011
I've had this for a few months now, and I have loved it so far. The reason I got this was because I had an old Kenwood KS-201 HT passive subwoofer laying around and I was missing the deep thump that my little Creative T20 desktop speakers couldn't deliver. Now I finally get the kick out of my music and movies. It would be nice if the frequency response would be a bit lower, like in the 20-30Hz range, but that's just my personal taste. Then again, for the price, I can't really argue since the sound is great.
Pros:
Easy To Setup, Great Sound Quality
Cons:
Lack Of Power
Best Uses:
Computer System, Basic Systems, One Room

Great desktop amp, Very versatile and packs a powerful punch to it. Also has very low harmonic distortion. A great company to deal with. I would also like to thank Linda for all her fast responses to my questions. Thanks to OSD i'll be back ;)
