QuestionHow many watts
Asked 4 years ago by Anonymous.
- Answer Rather than measuring in wattage which is just a measurement of power draw, we measure sound bars in sound pressure level, or dB. This sound bar goes as loud as 98dB with a frequency response of 50Hz - 20kHz

Asked 4 years ago by Bones.
- Answer As long as your "sony bravio 55" smart tv" has an HDMI ARC port (best) or an optical out port (better) or RCA out port (good), then you'll be able to use the Vizio M 2.1 soundbar.

QuestionIs this bar come with the remote control? Is it built with the woofer in?
Asked 4 years ago by Junior.
- Answer Yes and yes. It does have a. Built in woofer and it does come with a remote control. You can use the remote to ‘train’ your existing remote for volume up, down and mute. That way you won’t need to use the remote that comes with the sound bar. You can also use the included remote to change the settings of the sound bar. I changed mine to ‘dialogue’ and increased the treble. This makes conversations in movies much easier to hear clearly. After buying/using one, I bought another one for my second tv. They work great. Don’t forget to disable the sound on your tv so that the only sound you’ll hear is coming from the sound bar

QuestionWhat is the length of the power cord that is included with the sound bar?
Asked 3 years ago by Bernie.

QuestionIs there a tv mounting kit that this bar is compatible with? I want to mount it to the bottom of a swiveling tv mount. But the giant keyhole mounts on the back of the soundbar are not compatible with anything I can find.
Asked 4 years ago by guest.
- Answer I ordered a universal soundbar mount from an online retailer for around $20 and it came with the 2 bars that mount to the TV mount and then you can mount the soundbar to that. That kit included some sews and nuts and bolts too, which I made work when I used a drill to make the hole in the vizio circular soundbar mount lager to get the screw through. I would suggest that you get the soundbar and pull the circle mounting part out and take it to the hardware store and try different screws and nuts so you don't need to modify anything. You need a screw/bolt with a small head on it and some length to it to fit inside that circle mount and then get through it to mount it to the soundbar mount with a nut. Washers are likely not a bad idea to grab when you are at the store. Once you have that done, you can just hang the sound bar onto the circle mounts (That vizio intended for wall mount) that are mounted to the universal soundbar mount.

Questionwhats the max power output of this sounbar?
Asked 4 years ago by B11.
- Answer Vizio's website doesn't list an output power (i.e. in Watts). However, it does list the SPL rating of 98 dB and the lower frequency response of 50 Hz for the sub. So, with it having an SPL of 98 dB, that means it's pretty efficient and can get pretty loud. I can tell you it is plenty loud enough for me. I don't even have to turn it all the way to the max volume setting for me to be uncomfortable with the volume output.

QuestionI have a Vizio V505-H19 TV. The TV has HDMI arc and two HDMI inputs. I need an additional HDMI input. Can I use the input on the M21d-h8r? What input do I set the soundbar to if I do this?
Asked 4 years ago by Farmers.
- Answer The soundbar has an HDMI-In and an HDMI-ARC port. The HDMI-ARC port is meant to connect to the ARC port on your TV. If you set the TV to the HDMI input with ARC and you set the Soundbar to the HDMI-In port, it should work fine. I have an AppleTV connected to the HDMI-In port and then connect the ARC port on the Soundbar to the TV. No problems.

Asked 5 years ago by BronxDJ.
- Answer Wall mounting the Visio M21d-H8R on the included two brackets will stand off the soundbar from the wall about 1/4" allowing enough room for cables to go up to TV.
