A slim 2U, rack-mountable and cool-running multi-room amplifier, the MX1680 includes 16 channels rated at 80 watts each at 4 ohms/50 watts at 8-ohms and can be configured as the main amplifier for an audio distribution system such as for background music, paging, and multi-zone audio or as an amplifier for 5.1 or 7.2 home theater surround sound systems. Equipped with Class D digital circuitry, this slim but powerful amp keeps distortion low and efficiency high (93%). When used with an audio distribution preamp or matrix processor, each zone can independently drive one of several different sources by using each zone’s line audio inputs, and if a particular area needs higher power, then two zones can be bridged for 160 watts per channel x 2 at 8 ohms. Designed for Installation FlexibilityThis robust amplifier accommodates a wide range of audio applications with global and independent zone triggering, audio sense circuitry with adjustable gain/vol per channel, two Bus Inputs/Outputs and independent left and right line inputs per zone. With high performance and ultra-low distortion output, the MX1680 Multi-Zone Amplifier provides unmatched sound quality for any audio system. Pair with OSD Audio’s NERO Link Streaming Source Module to play Spotify, Tidal, Napster, Intune, iHeart Radio and other options through your Android or Apple smartphone or tablet.

I have this setup with a few AirPort Expresses that drive each zone via AirPlay. I like how it shuts off each zone if there is no active input so I don’t have to worry about any hums or hisses.I do have an issue where if I turn the volume down enough, the zones will turn off. I’m sure I just need to fiddle with the dials on the back to set the sensitivity.I’ve had this for almost two years and it works flawlessly every time I go to cast music. There is a fairly audible click whenever a zone powers on, but it doesn’t bother us.

I purchased the OSD MX1680 as a multi-zone music distribution amplifier for my home to replace an ELAN 1650 digital amplifier that died last week. I currently have speakers installed in 7 rooms and one set of speakers on our backyard patio for a total of 8 zones. I use Google Chromecast audio devices as audio inputs to allow apps such as Spotify to cast music selectively across the 8 zones.While I have only had the MX1680 installed and working for the past week, so far I am very impressed with the quality, the features and the ease of configuration/use. Shipping was prompt and the OSD MX1680 arrived in great shape two days after placing my order. Packaging was excellent with the manufacuturer box securely fit inside the shipping container (i.e. double boxed) . The MX1680 is much smaller and lighter, delivers more power and has many features that make it superior to the ELAN 1650. Each zone of the MX1680 has as slide switch that allows easy selection of line input, BUS1 or BUS2 inputs. I connect the Chromecast audio units to the two BUS inputs and set the slide switches to direct a common audio signal to specific groups of speakers so that the same music track plays in multiple rooms. This is very easy to configure and change if I wish to group the speakers differently. The sound quality is excellent with plenty of power (50W or 80W/channel into 8 ohm and 4 ohm speakers, respectively). I also really like the audio sense feature that activates channels when the input signal is present and turns off the channel after a few minutes when the no input signal is present. This should prolong the life of the unit and minimize heat generation when not in use.While I only had the unit for about a week, so far I am very impressed with the quality, features and performance of the MX1680 and would recommend the unit to others looking for an multi-zone music distribution amplifier. One item to remember, the channel volume controls on the back of the unit are all set to zero by default, so remember to turn up the volume settings as you install the speaker wires. Hope this is helpful....enjoy!

I bought this unit to use one Sonos and be able to output to speakers in 4 different zones. The clearly app is absolutely awful, doesn’t perform the requested action more than half of the time, making the whole point of this system completely futile. This is getting sent back, what a huge mistake!

The little volume controls on the back of the unit were all set to minimum/off from the factory. I spent 2 hours debugging and finally tearing my whole system apart thinking this unit didn't work. I broke it down to a single input and speaker right beside it and got nothing. Finally I started playing with the tiny volume controls and eureka it all started working.After that it was pretty easy to set up and had no issues. It would have been nice to have those controls set to some moderate value or at least have the setting of "off" noted in the instructions, or have a debug section. It could have saved me a lot of time, frustration, and wires spread all over.I'm happy with the sound quality and volume of the unit.

I read all the reviews on how hard this would be to set up and use the App. Setup was pretty straight forward. The product is ethernet wired only. There is no Wifi, so you will need to have it wired direct to your router. Don't get confused with Groups and Zones. The zones are the 6 zones that you have wired to the amp. The groups are only if you are running more than one ODS Nero Max 12. You will need to go into the App and into the connect / Info upon setup. Mine was able to find the Nero under Group 1 when I selected Auto Device IP. You will need to initially set the zone volume levels, treble and bass settings for each zone. You can do this when you name the zones. All zones sound pretty good. In each zone setting you can set the default source that you want to run on. I put all zones on source 6 and ran it off of a google chromecast connected to a HDMI extractor feeding an optical output. I connected the chromecast to my google home. Spotify sees it when connect. I can use my Google home to turn on and off the music. You will need to app to turn zones on and off. The system rocks with all zones playing.

I've had this product under 2 years now, at first everything was working as expected. but since 2 months the fan has started making lots of noise, I tried cleaning it, moving it but noise still persist.

screwed by them and Amazon... zone started to went out then it actually flamed and fumed... great buy it you want to loose $600 bucks. plus the crazy thing is that for that purchase, Amazon will not replace or refund after 30 days... which absolutely doesn't make sense.
