A solution for an outdoor speaker sound system
August 29, 2022
I needed to drive eight outdoor speakers, and clearly, I wanted remote control of their operation, and the ability to stream from Apple Music.
I could have utilized something like an Echo Link, or a Sonos Amp. But I rejected those options due to the cost (Sonos) and obnoxious assistive technology (Alexa).
What I ended up implementing is a bit of a Rube Goldberg machine, but it works well, and it did not break the bank. Here are the details:
- A Belkin SoundForm Connect adapter acts as an AirPlay 2 receiver. This satisfies the requirement of streaming any music I desire either from my iPhone, HomePod, or Apple TV. The only downside is that the AUX output from the Belkin device is horrible, as many of the reviews on Amazon also note. Luckily, the optical output is OK, so I use that instead.
- Because of the above-mentioned Belkin flaw, and the lack of optical support on inexpensive amplifiers (see below), a Digital Audio Converter is necessary. I settled on an inexpensive Amazon Basics DAC. It works well, and is USB powered, so I can run it from a power hub instead of using up another outlet in my network closet.
- Audio amplification is provided by a Nubsound 100W mini-amp. It has built-in Bluetooth, which I turned off, as I prefer to use AirPlay. The amp itself is remarkably small — about the size of a Tarot deck. (You were expecting a less esoteric analogy from me? OK. About the size of two sticks of butter.)
- Finally, I installed a Pyle Multi-zone Selector so that I can fine-tune the volume of each speaker pair. This also allows me to turn off speakers in unoccupied areas of the yard. (Because I’m a good neighbor.) A fancier solution would let me manage this remotely via my iPhone, but for under $100, this passive, no-power-required switch works well. It’s also small enough to fit, barely, on a shelf in the network closet.
Here’s a block diagram of how it’s all connected:
The system works well, with a total cost that is hundreds less than a Sonos solution. (And cheaper than nosey Alexa, too.) The only downside is that I have to stream from a device to the amplifier. The Sonos can independently connect to Apple Music. But this is a limitation that I can take to the bank.
If you need me, I’ll be outside listening to Poolsuite FM.
