Question: We have outdoor speakers. Can you add additional speakers to this unit?
Document: This unit is incredible. Forget about the Wave. Save yourself some money and headaches. This CD really works and does not jam. It's versatile and you can actually add on to it. Heck, it even has a USB outlet.
With it-you can control the music selection & volume. Guess what-you can do exactly the same thing with the supplied remote control if the ipod is sitting in the unit atop the receiver. Is this worth $110 dollars extra. I certainly don't think so.3. Apple makes an App called "Remote" that allows you to Control Itunes on your computer if you are willing to use your own computer speakers or powered speakers fed out through the head phone jack.
I just cannot help myself-poor impulse control is what I have when it comes to audio systems. I really like Yamaha products & then I saw this little gem in orange & I had to have this unit. It arrived today & I have been listening since. What have I found?1. Someone had mentioned the sound in their review that the sound sounded as though it did not get "outside" of the speakers. I think that fellow had good ears.
Allows the ipod to be like the supplied Remote Control with the ipod attached to the unit. Big Deal. And I 'd be willing to bet that many purchasers of this unit were not EXACTLY sure of just what they were paying for when they ordered it.
I got this product at the used price actually, in like new condition, Its the wireless yamaha mcr-140 model, not the mcr-040, and total it was about $200 instead of $400. It sounds fantastic for having 4" speakers, definitely louder and clearer than i had anticipated for sure, and it sounds clear with all types of music and different genres.
That's what a good pair of speakers will do. It gives the music an "ambient" effect. Like porn-you know it when you hear it. On the plus side-the speakers are accurate, fairly neutral, and have quite a good dynamic range with acceptable lows for a four inch box. So I have to say-that for what this little system will do-or should I say-what it will do realistically given its size-it does it quite well.2.
You can buy extra a "wireless woofer". What that means is no wires to that one speaker. You pay $112 for that option. The two speakers included are hard wired. The description of this system never says otherwise  BUT and I happen to thing it is a big thing and not well explained at all. But-what do you get for paying $385- almost $110 dollars more? You gets Yamaha proprietary wireless system.
So there is a choice. The yamaha unit has sleep timer;  so does the Itouch.So where does that leave me? I think I would have done a lot better by saving my $110. As I said-the 275 dollar unit would be a lot more cost efficient. But there are a few things I do quite like. This stereo with the Ipod becomes a net radio because I can get many FM station audio streams.
This is a compact system with a nice deep sound. The colour is great. I'd definitely recommend this to others!
There is no skip track button(s) on the face of the stereo however, so dont lose the remote. and finally, the color selections are nice and unique.
Answer: The unit does not have outlets for additional speakers; however, for about $10 (Radio Shack) you can get an expansion pad that allows you to connect additional speakers.  You just connect the pad to the speaker connections and then you will have an A & B capacity.
