I'm doing a kitchen remodel and thinking of using this amp to drive a pair of OSD in-wall speakers. The audio source will be an Apple AirPort Express w/AirPlay hidden w/the amp in a roomy cabinet. I see in the product photos that this amp has a rear switch for "auto on," but it is not mentioned in the specs/description. Does the amp "time out" and turn off, and wake when it senses a signal? My subwoofer in another room does this. This would be great as I would rarely need to get at it anticipating periods of non-use. Please fill me in. Thx! I love my prev purchases from OSD btw!

Thats great to hear! Thanks for shopping with us. The AMP120 does have the Auto Off.

Hi Dan:
If you are using a single input (source) use input number 2. The auto sensing works best plus you have dedicated output associated with the input 2 in case you want to add a powered sub.

will this AMP 120 be suffeciant to power two small patio speakers (4 inch cone woffer& 1inch silk dome twetter)and also your OSD-WR-150 outdoor package, thru a FM tuner. Thanks, PHS

Answer:
Phillip,
Hooking the 4 inch pair you have to the am120 will work out great. The wr150's are already powered so that wont be a problem.
CLBy Customer Service - Q&A on May 4, 2012
Answer:
Hi Phillip,
The FM tuner should connect to source Input #2 of the AMP120 and the wireless transmitter should connect to Output #2 of the AMP120. The internal amplifier will be ideal for your patio speakers while the Output #2 plays exactly what you have connected to Input #2. You can play whatever you have connected to Input #2 which could be an FM Tuner, iPod or even a laptop computer with internet access to streaming content.

I have a pair of Polkaudio Atrium 65SDi outdoor speakers (Recommended Amplifier Power is 10-125W continuous) that I would like to hook up beneath the 2nd story eaves as "Zone 3" using my Denon AVR3312CI, which allows for 3 zones of music. The problem is that I need an extermal amplifier to power up Zone 3. Five of the Denon's 7 channels are dedicated to a home theatre and 2 are dedicated to Zone 2 stereo, leaving no more channels for Zone 3.
Please advise how much power the AMP120 Pro would drive to my Zone 3 Polk 65SDi speaker pair. Conversely, could the AMP120 Pro damage these speakers by driving too much power? Would you recommend another amplifier?
By Customer Service - Q&A on March 11, 2012
Answer:
Hi James:
The Amp120 would output around 50 watts a channel full output as long as you connect your Polk speakers as a single right and left speaker connecting only one voice coil (each speakers has an option to connect either a single or dual input). In the single input you connect one for right and the second speaker for left so you have a stereo pair. In order to take advantage of the Dual Voice coil feature of the speaker (a better option for your application) we would recommend purchasing the AMP200 (a true High Current amplifier). You would then connect the Speaker A outputs (right and left +/-) from the AMP200 to one of the POLK speakers (make sure to flip the switch saying dual stero input) Then connect Speaker B (R&L. +/-) to the second speaker. This will create a 4 ohm load on the amplifier while increasing your output potential to 125 watts per channel. This is a true audiphile amplifier featuring a Heavy Duty Toraidal Power Supply, Ample internal Heatsink and totally discrete output devices. That is why it weights almost three times more than the AMP120 and costs almost three timesas much. It also matches up better to you speakers. These will become stereo speakers which will provide better coverage in your outdoor enviroment. I hope that helps, thank you for considering OSD Audio.

Will this amp drive five zones (indoor) with pairs of ICE610 ceiling speakers in each zone and using your ISS6 speaker selector along with your VMS100 slide control volume controller in 4 of the 5 zones? If not please make sugestion.
By Customer Service - Q&A on March 12, 2012
Answer:
Hi Ross,
The AMP120 would work but might not have the power you need. The AMP200 with the ISS6 would work best. You should use a fifth volume control for zone 5. Use a volume control for each zone to make the impedance match properly. Then, make sure to keep the impedance protection off on the ISS6.

Can I connect my Ipod directly to this amp? If so, how?

By Customer Service - Q&A on March 22, 2012
Answer:
Hi AP,
The Amp120 features two RCA signal level inputs which are dual female RCA connectors for both Input #1 and Input #2. Marked as red for right and white for left. Input #1 takes priority when both are connected and active. When you shut off the source for input #1, input #2 plays. You have two options for connecting your iPod directly to one of the two inputs. The first option you will need is a mini 3.5mm to RCA adaptor cable (see RCA audio cables under the audio/video cables tab). The mini 3.5 connector is plugged into the headphone output of your iPod then the RCA's are connected to one of the inputs of the AMP120. A second option would include adding an iPod docking station such as the Sherwood DS-10 (Go to category/whole- house audio systems/iPort In-Wall Docking Station for iPod/DS-10). This connects to the AMP120 with a standard RCA to RCA patch cord (R&L stereo). You plug your iPod into the dock and not only does it charge the iPod but it also allows you to control the iPod functions with the remote control supplied with the DS-10. When connecting just a single input to the AMP120, use input #2, which features a dedicated pre-amp out that allows you to add a powered subwoofer like our P10. Thank you for considering OSD products.

Does this have a Aux and do you need to run wires from the speakers to the amplifer? Does it play the radio? I am interested in buying 6 speakers and cd player or something I can plug my ipod into. Thanks. Do you guys install, if so how much?
By Customer Service - Q&A on November 8, 2011
Answer:
The AMP120 has dual inputs with automatic source switching. It is not wireless, so you must run speaker wire from the Amp to the speakers. If you are planning on connecting up to six pairs, we recommend adding a speaker selector like our ISS6 or DSSM6. This will take care of the impedance matching needed to operate the amplifier safely. You can also add volume controls in each room, which would be wired between the speakers and speaker selector (located near the AMP120). You can plug both your iPod and a CD player into the AMP120; however, you will need a 3.5mm to RCA adapter cable to connect the iPod to input #1 of the AMP120. You can then add a second source, either a CD player or perhaps a laptop where you can select from your iTunes library or a number of streaming on-line radio stations. This would be connected to Input #2. Then whatever you have connected to Input #1 has priority over Input #2 while it is active. Sorry we do not install but we do feature a number of Do It Yourself videos on our site regarding our in-ceiling and in-wall speaker installations. We also offer technical support at 888 779-4968.

I am looking to add rear speakers to a TV without purchasing an expensive tuner/amp unit. The RCA jacks on the back of the TV are not capable of powering the speakers directly. Will a unit like this be able to hook directly to the back of the TV and power additional pairs of speakers?
By Customer Service - Q&A on January 29, 2012
Answer:
Hi Tom:
The OSD AMP120 will allow you to connect an external set of speakers especially if you have signal (low) level output, right and left RCA connection. I not sure if this will work if you are planning to add rear surround speakers to your system hoping to recreate the surround channels of a standard 5.1 system. There is away to connect to the rear speakers to give you a quasi surround sound effect. Set the AMP120 to bridge or mono mode than connect the positve outputs (marked bridge outputs, A L+ and R+) to the positive posts of the speakers then connect the negative from the right speaker to the negative speaker to the left negative terminal. Don't take my word for it chaeck out the link to the Monkey Wrench... http://monkeyfighter.com/surroundsound.html
The only difference is they are connecting two pair of speakers while you are using the Monitor or Television speakers for the front speakers already. You can connect the rear speakers full range at first which you might want to try so you have a reference for comparison.
I hope that helps...

I want to power 4 outdoor speakers at the same time. 2 by the patio, and 2 by the pool. Is this the amplifier I am looking for?
By Customer Service - Q&A on November 17, 2011
Answer:
This Amp is not meant to power two pairs of speakers at once for long periods or at High Volumes. The AMP200 would be better suited for your application where it has a true 2 ohm rating. The outdoors typically is more demading because your trying to fill a larger area. Choosing a 6.5" speaker over a 5.2" or even an 8" pair over a 6.5" for the outdoors is also helpful. You could even connect a second pair of speakers in each zone with the AMP200. Two pair in the Patio off of the Speaker A output and two pair of Rocks for the Pool. You also can connect a second source as well (but only one will play at a time with input #1 taking priority when it is active). This amp weights three times as much as the AMP120 featuring large internal heatsink and a true audiophile quality Toroidal Power Supply.

Have sony STRDE1075 that has "2nd Room" output. I purchased your ISS4 High Powered 4 speaker selector. I would like to now power a set a Bose Surround 51 outdoor speakers, OSD's CW540 SQ and (2) ICE640TT (both with volume controls. Will this amp work well for me. Currently, my old Sony STRDE845 only has a A/B speaker select and "B" is hooked up to ISS4 speaker selector. With all four speakers wired to ISS4, (not even on, just connected) my Sony STREDE845 shuts off with a "Protector" activated. Can I resolve the issue by adding the AMP 120 Pro series with a connection to my newer Sony STRDE1075 with "2nd room" output?
By Customer Service - Q&A on November 26, 2011
Answer:
Hi Jeff:
Adding an AMP120 will help, but first let us see if we can address your inituial issue. You have 4 pairs of speakers connected to a ISS4 speaker selector using volume controls. I am assuming the volume controls are impedance matching like our SVC100 and are you are using a volume control for each pair of speakers. In this case the impedance matching setting on each VC should be 4X. Then make sure that the proection switch of the ISS4 speaker selector is set to off (de-activated). Using the protection switch with volume controls causes a conflict. Most Japanese designed Receivers feature a relay to shut off at any sign of a unusual load. Adding an external amp like our AMP120 would work but you would have much better results driving the four pair of speakers adding our High Current AMP200. Having a Speaker Selector, four volume controls plus the four pairs of speakers creates a demand on any amplifier. A High current amplifier is designed for such a setup.
