Chord Electronics’ new Poly module enables the award-winning Mojo headphone DAC-amp as a fully fledged high-resolution wireless network music player, streamer and SD card playback device, with smartphone control.

Poly removes the need for a wired link between smartphones and Mojo,and allows a world of content to be decoded and played back using Chord’s proprietary DAC technology.


Poly is based on a condensed high-level PC, with data server, DLNA streamer, Wi-Fi hub, Bluetooth module and SD card reader/player functionality, and highly sophisticated software.




​

Poly acts as a Wi-Fi and Bluetooth hub and can access music in a number of ways including streaming over Wi-Fi, network storage devices (NAS) and collections stored on SD cards. Bluetooth connectivity and AirPlay functionality providefurther flexibility and enable mutliple Mojo/Poly combinations to be used throughout the home, providing a high-quality multiroom streaming playback solution.


Highly advanced yet miniaturised as a plug-in module for Mojo, Poly has been designed for full control using the best (and most familiar) user interface in the world — the smartphone.

When connected to Mojo, Poly conveniently slips into pockets, bags and handbags — it doesn’t need to be hand-carried or regularly checked like other players. Mojo was always a smartphone-enabling device and the same is true of Poly.

3. Playback of audio from a host device to Poly via Wi-Fi or Bluetooth. File data is read by the host’s MPD music player app and pushed to Poly for output via Mojo
4. Roon playback pooled from multiple sources including local Micro SD card storage on Poly, storage from host devices, network storage and streaming service storage simultaneously. All audio playback will be pulled through to the Roon application for decoding then pushed back out to Poly to output audio via Mojo
5. Playback of audio stored on local networks. Music on connected network storage devices can be accessed via W-Fi, for example, a Synology drive read by Poly, decoded and output through to Mojo for playback

Here are some additional tips put together by Matt Bartlett Chord’s Manufacturing Director
1. Poly Lights:-
a) Flashing blue then green means Poly is in access point / hotspot mode.
You will be able to see a WiFi network called Poly to connect to and then use the
config webpage to make changes to Poly setup. Bluetooth will not function in this mode.

b) Solid light means Poly is connected to a WiFi network. The light will be blue when fully charged,
then green, yellow, red as the battery depletes. The important thing is that the light is solid and not flashing.

c) Flashing Blue means Poly is connected and playing via Bluetooth.

d) White means Poly is on charge.

2. To access the config webpage Poly must be in access point mode and the light must be flashing green and blue.
You will see a WiFi network called Poly followed by a number. Connect to this and the webpage should automatically
appear. If you don't see the webpage open any browser and type poly.audio into the search bar.

3. Poly hotspot mode can be permanently switched on. In this mode it will always use it's own internal WiFi router and will not
connect to the internet or any other WiFi network previously stored. On the config webpage navigate to the Play mode settings
tab and check the tick box marked Keep in hotspot mode.
Note:- Hotspot mode is the same as access point mode where Poly will be broadcasting and connected using it's own internal
WiFi router so the lights will flash blue and green.

4. Phone hotspot mode should be setup in the same way as any other WiFi network.
Enter access point mode on Poly (flashing blue and green lights) and open the config webpage.
On the WiFi settings tab add your SSID for your phone hotspot and the password. Tick the reboot
on save box and the click the save button.
Note:- Make sure your phone name (SSID) does not include any special characters like a dash or apostrophe.
So don't use the name Bob's iPhone - instead use Bobs iPhone.
On the iPhone you can rename your phone by going to settings - general - about - name.

5. If you are having trouble getting Poly to remember WiFi settings then make sure you tick the reboot on save box
before clicking the save button. This will force Poly to reboot and change settings.

6. Apple Airplay will only output a 44KHz sample rate signal. This means the light on Mojo will always be red even if
you are playing a high resolution file. To play high resolution make sure you use a DLNA/UPnP app such as
8Player or BubbleUPnP where you can select Poly as a renderer output.

7. Tidal on the iPhone will only output using Airplay or Bluetooth. On android phones you can use apps
like BubbleUPnP which include Tidal integration to play music directly to Poly as a renderer.

8. Checking the saved WiFi networks. On the config page is a tab called Manage Connections.
This will show all the WiFi networks setup inside Poly. Here you can delete them if you want to.
Poly will automatically connect to all the WiFi networks listed providing they are in range and
then it will connect to the strongest first.

9. If you have your headphones or HiFi system connected to Mojo then you can make Poly
'speak' the mode and IP address it is connected to. Just give a short press on the config button
and you will hear Poly announce the settings. If you press and hold for more than 2 seconds then
Poly will say 'entering access point mode' and it will reset

I have a question that involves switching Poly from working on a WiFi connection in my house to Roon playback and vice versa.

PhilW said:

Keep headphones connected and press the config button until it tells you. Going into roon mode. When you hear that release the pin. It will be in roon mode without access point mode

For the people with the library rebuilding issues - are you guys using an MPD client, or a DLNA client?

My understanding is that there are 2 ways of playing SD card contents via the mojo:

1. Use a DLNA client and configure it to us the library from the poly, and set the renderer to the poly so that it's effectively straming from itself to itself (I'm not sure if the data goes via the phone?)
2. Use an MPD client which is designed by default to remote control a server elsewhere and just send commands like "play"

I am using MALP on android - an MPD client - and I can confirm that after restartng the poly, even though the library is rebuilding (and takes some time), i am able to browse and use the old library.

e.g. I had 4 folders of music working, I stopped poly, loaded more, restarted poly and i was able to play the existing 4 albums. After a while, the other 15000 songs appeared for use. After turning off the poly and restarting again, all 15000 songs are available immediately each time.

After I start the poly, I can always immediately use the MPD client, but if I switch to BubbleUpnP it takes time to rebuild the library each time (though maybe not more than 10)...

Hope that helps!

I believe what made a difference to me was turning on hotspot mode on the phone while the Poly was rebooting. Previously I was waiting until Poly was flashing blue before turning on hotspot mode on my phone.

Gapless playback - not sure if this has been mentioned before so apologies if I'm repeating.

Discovered last night that MPDluxe on iPhone playing 44/16 FLAC files from the SD card provided gapless playback.

mojo ideas said:

When designing Poly the user's convenience and freedom from cables was the key objective. Poly provides a small easy way of providing a Mojo Ready streaming solution that has the capability to play current Audio formats whilst having the ability to be remotely updated to accommodate new Audio standards as the appear.

Poly is much more than just an SD card player, having Roon integration, DLNA support and MPD functionality all without tying you to any one App.

.... I'd like to be able to play an album on the inserted SD card, program it via my phone's hotspot, and then leave my phone at home and go for a run (just like in the branded video Chord have posted online).

This will be part of the chord Gofigure app so you can set a playlist playing then
leave your phone at home if you want to.

DLNA works by sending transport commands to Poly to play each
track. If you close down the DLNA app or leave your phone at home
then Poly will not get the commands to keep playing and so it will
stop.

You will be able to use your existing applications to stream to Poly via Airplay, DLNA, Roon, and MPD to play the media from the SD card regarding MQA we are in conversation with Roon on this matter

With TIDAL integration will Poly receive TIDAL MQA streaming? Tidal website states TIDAL MQA is currently via Desktop only, so not sure if the Poly is supported?

Click to expand...

We are looking closely into the technical support for MQA within the realm of our total support for the Roon playback system through Poly. We will not however be implementing any changes to the already advanced decoding technology within our Dacs.

We are running our multi processor cores at a very fast rate over 2GHz so Poly is extremely powerful so it won't suffer from glitches due to processor waiting time and over use like other typical mobile systems. Poly is not normal technology it far higher than the usual hence its price is more than you all wanted but we had to do this right. It's frustrating when so many guys are saying so much ill informed comment against us when all we are doing is trying to bring truly innovative ideas to market that have been properly engineered.

mojo ideas said:

The price of Poly has not been inflated we at Chord always follow precisely the same Bill of material to selling price ratio. Yes we could have used a cheap single core processor that runs a fraction iof the speed we are running and had no coprocessor. The price is what it is because Poly is what it is please don't judge Poly when you are not fully aware of a Polys cababilities Poly is an amazing product with truly world first cababilities! Yes we could have built it cheaper but it would not have been able to do half of what Poly can do.or at the speed that poly can do it Please hold your fire until you can fully understand what Poly really is about. I would have hoped that by now all of you guys would understand that we at Chord care greatly about what ultra high technology we design. There are many rip off merchants that bring cheap low technology solutions forward with the hope of selling them to the gullible we are proud not to be one of them. So the price of Poly is the right price it could only be Cheapened by crippleing its performance and I'm very sorry but we as a company are not prepared to do that .
