What special equipment would enable the 670 to transmit to wireless headphones?
Hi David,
the DGX-670 can only
play external audio (e.g. from a smartphone) via Bluetooth (BT). But you cannot
transmit the DGX -670 audio output via BT (e.g. to BT headphones).
As I just said in another thread, you have to use an external wireless transmitter that is connected to the PHONES/OUTPUT jack of the DGX-670.
Note:
Digital wireless audio systems (e.g. Bluetooth) can have a relatively high latency (delay) so that playing live is practically impossible. The latency should be less than 10 ms (milliseconds).
Best regards,
Chris
