I accepted the idea that there is no wireless connection between Djay and speakers yet. Let’s wait a few more years.
The best I could find is a compromise between sound quality and portability.
If of interest, these are my setups:
- Fully portable setup - iPhone and airplay.
Cons: The latency (2s) and no precue possibility;
Pros: Audio resolution is high, e.g. to support potentially any speaker volume; small investment; few components to manage.
This solution simply involves having Djay in the iPhone and then use Airplay to connect to the speakers (needs also an intermediate DAC and amplifier), and it could potentially work also with the setup below, but I haven’t tested it yet.
- Semi portable setup - iPad and external soundcard
Cons: hardware and cables required; some cable connections are unstable; cost; several parts to manage; ‘lower’ sound quality.
Pros: ‘plug and play’, once setup no more changes needed; precue possible and no noticeable latency.
This solution involves connecting the iPad to a USB hub, which then connects via USB C to a 2 channel external soundcard (one channel for output and the other for precue). The main out then feeds into a Bluetooth transmitter directly to the speaker. The USB hub powers iPad, soundcard, and transmitter. I can ‘plug and play’ the one USB C cable and I am good to go. Cables can be a pain, especially the USB C connection to the iPad and the USB B connection to the sound card. Bluetooth is stable and only needs to be paired once.
My current setup has an old, crappy Bluetooth transmitter/receiver pair delivering 320 kbps at 16 bit (?) and around 30 ms latency (little noticeable), i.e. Spotify quality - although I am not able to quantify the audio quality loss is in the DADA conversions to connect soundcard, Bluetooth pair, and speaker.
Depending on the intended use, this setup can be cost-effective (read cheap) and workable. One can also add a stand-alone Bluetooth pair for the headphones.
A modern Bluetooth transmitter/receiver pair can give almost CD quality, no latency, and a stable connection for under 200$. Definitely a reliable technology and stand-alone in the setup. I will try to develop a system that allows me to stay digital until the speaker side Bluetooth receiver.
Of course, I would still like to DJ using the full definition and quality potential of my audio system using wifi streaming, and I reckon this is still not achievable and not in sight, especially in regards to audio quality.
I can post the list of the components I have if of interest.
I hope this helps.
