Chord Electronics Poly (Mojo wireless network module)
The Chord Poly, a revolutionary new network module which is set to introduce high-res wireless streaming, SD card and network music playback to Mojo, with both smartphone control and playback.
Chord Electronics’ new Poly module enables the award-winning Mojo headphone amp/DAC as a fully fledged high-resolution wireless network music player, streamer and SD card playback device, and offers wireless playback and control from smartphones. Poly removes the need for a wired link between phone and Mojo for the first time, 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 receiver, Wi-Fi hub, Bluetooth module and SD card (using MPD) 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 using Mail Player Daemon. Bluetooth connectivity and AirPlay functionality provide real flexibility with smartphones and enable mutilple Mojo/Poly combinations to be used throughout the home, providing a high-quality multi-room 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.
Poly is compatible with the latest high-resolution-audio file types and supports PCM files up to 768kHz resolution and DSD64 to DSD512 (Octa-DSD). Poly’s high-quality SD card reader/player frees up smartphone memory and storage, so vast libraries no longer need be kept locally on phones.
Chord Electronics and its design partners have made Poly’s high-speed technology fully mobile: Poly includes a rechargeable LiPo battery giving around nine hours playback from a sub-four-hour charge using the device’s fast-charging circuit. Both Mojo and Poly can be simultaneously charged using Poly’s Micro USB connector. Poly is precision-machined from aircraft-grade aluminium and hand assembled in the UK.
Poly can be controlled with a wide range of music playback apps for both Android and iOS devices, with AirPlay offering additional compatibility and intuitive operation with enabled devices. Poly also integrates with advanced music players such as Roon (excluding SD cards). Supported file types (to be confirmed) include: ACC, WAV, FLAC, AIFF, OGG VORBIS, ALAC, WMA and MP3.
The name is derived from the ancient Greek word meaning ‘a large number’ or ‘many’. The moniker is ideal for a product that is capable of incredible, wide-ranging functionality.

- Playback of SD card audio. The file data is pushed to the phone for selection within a dedicated (MPD Music Player Daemon) app. When playback is initiated the command is sent to Poly for output via Mojo
- 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
- Roon playback pooled from multiple sources inc. 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
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
