Lifetime Tech Support

The XMP100 is the digital Class D version of our popular AMP 120 amplifier. This amp will also power Dolby Surround Sound systems and enhance the power of OSD outdoor speakers. Automatic source switching enables users to connect more than one source to the amp, so, for instance, you could use it to power both a DVD player and an iPod. The XMP100 has the ability to automatically switch sources, as well, if you choose to go from listening to music on your iPod to watching a flick on a DVD player. The power amplifier has 75 watts RMS per channel and bridgeable outputs for 160 watts RMS. An input of 1.4 volts is needed to reach full output and the signal to noise ratio is 107dB (A-weighted). The Dual Source 2-Channel Stereo Amplifier XMP100 has front panel-mounted volume and balance knobs and comes with a two-year warranty. 

Connecting Your Smartphone is Easy! 
A great feature of the XMP100 is the ability to connect your smartphone, iPod, or other portable music device (as long as it has a headphone jack). The XMP100 includes two RCA signal level inputs marked as red for right and white for left. All you need to do is purchase our inexpensive RCA to mini cable (see RCA audio cables under the audio/video cables tab). The mini 3.5 connector is plugged into the headphone output of your device then the RCAs are connected to one of the inputs of the XMP100. It's that easy!

What's on your mind?

David • 12/17/2019, 2:17:43 PM I use the xmp100 to power two OSD rock speakers in my back yard. I'm having the same problem as Bryan from Merrimack, NH has when using a sonos connect as input to my xmp100 amp and using the auto-on/off feature. I'm thinking I might want to set up a manual 12-volt switch I can use from my patio to power the amp on and off. Do you have a product that meets this need? If not, can you point me to somewhere I can find one?
Customer Service • 12/17/2019, 2:17:43 PM
Hi David: This is the review from Bryan in NH. He says the auto-on works: Just what I needed I'm running this XMP100 with a Sonos Connect powering a set of AP525 speakers on my front porch. I'm very happy with the sound -- nice and crisp. The auto-on feature works (yay!). I always like to use a dedicated amp instead of a Connect: AMP. I'm glad OSD offers an auto-on amp for around $100. I have a Class A/B amp that drives my pool area speakers and I can't tell a difference in the sound quality compared to this Class D. Did you make sure the amp switch on the front was in the on position? It needs to be on for both options either Normal or Auto-On. It also takes 5 to 15 minutes to go into standby. This amp also can run two pairs of speakers (A/B) something the SONOS Connect AMP does not recommend. Let us know if that helps. TL/5081
Chris • 12/17/2019, 2:17:43 PM Could I install this outside under a covered patio? It would get hot and cold with weather, but stay dry. I have power out here, but no speaker wire run. So wondering if I can just mount this next to speakers with a chromecast audio for the source.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Chris: I believe that would work, you will need two power outlets, one for the XMP100 and a second for the Chromecast Audio. You will also need a 3.5mm to RCA adapter cable to plug the 3.5mm to the Chromecast Audio and then the two RCA connectors into the Right and Left Mains input of the XMP100. You have a nice outdoor season in that part of Texas (not as much humidity as Houston South). You might plan to bring inside for the short offseason. I mean you had Snow for the Super Bowl so your Winter can get a little crazy. TL/5086
Rmr • 12/17/2019, 2:17:43 PM I am looking at adding this amp between my Samsung TV to power up my AP640 speakers I purchased from you previously. Will it work and what will it take?
Customer Service • 12/17/2019, 2:17:43 PM
HI RMR: You will need to make sure you have a variable audio output connection from either your TV (check the owners manual) or your cable or satellite box. You may need to turn your internal TV speakers off as well. The XMP100 would be a great match for your AP640 Patio speakers. You will need an RCA stereo patch cord to connect from either the TV or the set-top box. You will connect to the main inputs of the XMP100. Another option would be our NERO Integrated Power Amplifier which features an internal Bluetooth Receiver. Plus a choice of connections between the TV and the NERO. There is a Digital Optical option so you would be making a direct digital connection (the best option). Good luck TL/5120
Ed • 12/17/2019, 2:17:43 PM Can I run a+b with channel a bridged and channel b running two 8 ohm speakers? The manual says one set of speaker outputs can be bridged at a time, but not if you can then use the other output...
Customer Service • 12/17/2019, 2:17:43 PM
HI Ed: Good question. But the XMP100 just like our AMP200 and AMP300 are limited to bridged connection off Speaker A with no other connection to Speaker B. When Bridged it also becomes critical that it is an 8-ohm connection. That is the same whether it be a $99.00 Amp or $350.00 like our AMP300. TL/5146
Jerry • 12/17/2019, 2:17:43 PM Will this amp work for two, polk atrium 8 speakers ?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jerry: The Polk Audio Atrium 8SDI speakers are a Single Stereo Speaker with Dual Voice Coils (dual Input) plus a unique Dual application switch. You have two options with these speakers. First, you set the dual application function switch to Dual Input Stereo Switch and connect both inputs, one left and the other the right speaker input. That would mean connecting two of these speakers in parallel which would drop the impedance down to 4 ohms. The XMP100 rated at 75 watts at 4 ohms, 50 watts at 8 ohms. That is what the amplifier would see if you connect just one of the inputs for each of the two speakers and set the Dual application switch to single Mono left or right. You would be combining these two speakers as a stereo pair with double the tweeter output per speaker. The XMP100 would see an 8-ohm load from this connection. So no problem playing two of the Atrium 8 with the XMP100 since you would connect to Speaker A; Right and Left output only. When combining two of these speakers as a single stereo speaker, you will be using both Speaker A, left and right output and also speaker B left and right outputs as well for the second speaker. These would create a 4-ohm load on the amplifier and have 75 watts per channel. You would need to press both Speaker A and Speaker B switches at the same time. The XMP100 will handle either of these applications/connections. God luck TL/5191
