QUESTIONS & ANSWERS

By Michael from Salt Lake City on March 24, 2012
I want to use this amp in connection with your 8 speaker selector in a whole home audio setup. Do I have to have a stereo receiver to connect to this amplifier or can I hook a dvd player directly to this amp using the RCA inputs? In other words, do I have to connect the dvd player to a receiver and then hook the receiver to the amplifier or can I just hook the dvd player directly to the amplifier using the RCA outputs on the dvd player connected to the RCA in puts on the amplifer---without going through a stereo receiver?
By Customer Service - Q&A on March 26, 2012

Answer:
Hi Michael,

You can connect your DVD player directly to the RCA inputs of the AMP150. You also have a second set of inputs that you could connect either to an iPod, iTouch or iPad directly to the AMP150 using a mini 3.5mm to RCA adaptor cable (see our audio cables). The 3.5 connects to your audio/headphone output. You could also connect directly to a laptop or computer using the same cable and use your iTunes or Windows Media library as a source. The computer also gives you an option for streaming content from the internet including Pandora. You can also add Volume Controls for each zone for more control, and we have huge selection of in-wall, in-ceiling speakers for inside the house and a large selection of Rocks, Patio and Garden speakers for the outside. We also feature a number of choices of CL3-rated speaker cable as well. Thanks for considering OSD Audio products.

Just as a reminder, you asked:
hi, i have a quick question, would this be an amp i could use as a booster amp that could be connected from the speaker line output of my current recvr/amp to the speaker line input of this amp ?? current sony recvr is pushing 105 watts ,,, would it effectively increase my power output to my outdoor rock speakers or would it not ??


You can use the speaker output of your receiver into the "speaker in" of our AMP150 to do just that!, addl question:: as an additional question: in hooking up this amp to the speaker line input coming directly out from my reciever, will i get the increased power out put connecting the output to the speaker line OUT bannana plug outputs ?? approx how much of a boost will i get ?? 8 ohm system--stereo but ive got 3 speakers per side im pushing... pls advise and thx, Lou

Answer:
Lou,
So you have 3 pairs? How are they wired (parallel, series or daisy chained?)
Connecting your receiver to the AMP150 this way actually brings that Hi level output down to a Low level (signal) So you are not combining power, you are starting fresh with an amp that works superior with a 4ohm load, and unlike your receiver can handle driving all your speakers more efficiently.

I am installing a mono system and plan to have six or eight speakers when finished - will this amp mix stereo into mono and how many speakers will it power...plan to use a speaker selector switch to only run one or two speakers at a time, but maybe more - also thinkinng about running two seperate systems for front and back yard - only four speakers instead of eight. Just not sure how or what to do.

Answer:
Hi Chuck:

Based upon your question and information you have supplied this amplifier can work for you. I would suggest you think about using our Dual Voice Coil speakers where you can use a single speaker (Stereo summed Mono) for each of your loactions but you connect them in stereo, 4 conductor right & left (+/-). You can connect two DSM4 (4 zone)speaker selectors to each output of the AMP200 (Speaker A and Speaker B). You would run 16 gauge 4 conductor cables from the Speaker Outputs of the AMP200 to the DSM4 Speaker Selector. Then you use the same 16 gauge 4 conductor speaker cable from ther DSM4 to each indivudual Dual Voice Coil speaker. We feature a DVC In-Ceiling Speaker (ICE640TT), a DVC Patio Speaker (AP550TT Black or White) and DVC Rock Speaker (RS800TT Brown or Grey). This will allow you to connect from six to eight individual speakers. You even have the option of running stereo pairs in anyone of the dedicated zones space allowing. It sound like you are designing mostly for background music but this allow you to add a stereo pair for more critical listening in select zones. Note all of our Dual Voice Coil speakers are sold as indivudal speakers. We have anumber of oprions for you including the Four Conductor CL3 rated speaker cable (16 and 14 Gauge), Volume Controls and Speaker Selectors. Please feel free to contact us if you need further clarification.

Works as advertised
March 26, 2012
What I really wanted was a 12 channel amp. to run 6 sets of speakers. However I didn't have the depth in my cabinet. I bought this to run just my outdoor speakers (I have four sets on a Pyle Pro speaker selector)). *A side note on speaker selectors - If this is how you plan to run your system, beware that all of the speaker selectors I saw were not rated for enough watts to bridge this amp into (130W). Overall, so far so good. I've had at least two pair running at the same time (rear patio and garage) and it seems to put out enough power. I am not into listening to overly loud music and don't claim to be an expert. Just your average Joe looking to get music throughout the house. Works great for me.
Pros:
Easy To Set Up, Accurate Controls, Good Power Output
Best Uses:
Basic Systems, Home Theater, Multiple Rooms / Whole House

Still a great amp for such a low price
September 6, 2011
After a month of usage my prior positive review still stands. Now I'm just doing it again as a certified buyer of the product. I've had numerous house parties and no less than 5 of my guest were so pleased with the sound of my setup that they wanted all the part numbers to duplicate it in there homes. I got this amp to power my whole hose ambient audio speakers. My receiver was up to the job of doing it but I wanted a little extra power and I liked the dedicated bass adjustment. But my primary reason was to protect my $1000 Denon amp from damage and use this amp as a sacrificial lamb. I have outdoor speakers and in-ceiling speakers all throughout the house so I was worried about Murphy's law like a lighting strike or something hitting the house and going back to my receiver. At least this way it has to go through my speakers, volume controller, speaker selector, and then this amp, before it gets to my zone 2 RCA output on my Denon. Pros: - Plenty of power for over 14 8" in ceiling speakers all running at the same time in separate zones. I'm only using about half its volume/power range for all my speakers and that's more than plenty of power and sound. - Small form factor that is suited for either shelf mounted or rack mounted. Includes bottom rubber feet for shelf mounting and rack mount brackets as well. Both installed out the box. - The Bass feature is great to adjust the bass output to in celing speakers which normally don't reproduce bass very well. - Like the fact that you can also use a pair of speaker wires as an input rather than just RCA plugs. With RCA plugs from my receiver I lose the volume control from my receivers amp. But if I use the speakers input I can adjust and mute the volume with my remote. Also good for connecting to audio devices that don't have any RCA outs. Technically you can strip the wires off a pair of headphones and plug them into this amp and power some pretty large speakers from an MP3 player. Cons - The power LED is really one of those blue LED's from a flashlight. So it is absolutely blinding! I mean it really hurts to look right at it. Unless you have this in a cabinet or cover it with some tape it will illuminate your room in the dark. - I like the built in fan as it helps with cooling. But it is pretty loud for such a small fan. Now an issue if you have it in a cabinet or an enclosure. But if you get this to use as a bookshelf or desktop amp within arms reach the fan noise may disturb you. It seems to be a temp controlled fan as it is constantly switching on and of and changing speeds.
Pros:
Great Sound Quality, Good Power Output
Cons:
Power Led Is To Bright, Built in fan is loud
Best Uses:
Multiple Rooms / Whole House

Driving 4 sets of speakers
August 12, 2011
I got this amp to drive the speakers in 4 rooms. I initially was over-driving the amp, apparently, because I was getting some distortion, even though the red warning lights were not on. After I cut the output a little, it seemed to be a lot happier. I can't say the sound is great because each room has a different sound, some better than others. My ceiling speakers were installed by a contractor, so I'm not sure he did them all properly. So I'm not blaming anything on the amp. I would say the amp is adequately performing it's designed task. The shipping was quick enough, the price was reasonable, and I'm thus far happy with my purchase.
Pros:
Good Power Output, Easy To Setup
Best Uses:

Good product, hidden essentials
July 28, 2011
I got no output to the speakers until I discovered a tiny gain control on the rear of the unit, adjusted with a small screwdriver, that makes the difference between no sound and what sounds like megawattage. It wasn't obvious in the manual at all.
Pros:
Good Power Output
Cons:
Difficult To Set Up, Hidden crucial control

Good amp for the money
July 14, 2011
I use the amp to drive four pairs of speakers in 4 rooms thru a selector. So far, it's doing a pretty good job. I had to play with the levels a little to keep it from being over-driven, but I'm satisfied with it's performance. If it lasts a long time, I'll be very happy with it.

Easy To Setup, Good Power Output

September 8, 2010
I had purchased the OSD AMP300 before and very happy about the sound quality and craftmanship of the product. Now I need a smaller amp for my outdoor setup, and I found AMP150 perfect matching for amy application. Like other OSD products, the sound quality is very good and price is very competitive. Highly recommend for 2 or 4 pairs speakers powering. It can produce some very good bass.
