I’m trying to use my wiim pro to transmit to a wiim mini for rear channels in my surround set up. I’m using analogue in from the rear pre-outs on my reciever, and then sending the signal via Bluetooth to the wiim mini into a seperate amplifier. Unfortunately the Bluetooth signal has massive latency and cannot be compensated for via my reciever settings. Am I missing something?, is it possible to reduce latency?, is there a way to transmit the audio via Wi-Fi? Sound quality is fine, but the audio delay is about 1second???
