RemoteMix One - Cabled Mobile Phone Audio Interface

RemoteMix One combines professional audio electronics with a flexible communications interface which connects to mobile phones for broadcasting, all housed in a rugged new belt pack design. It is based on the well-liked BluePack – but without the Bluetooth – to allow live “man-on-the-street” interviews using a cell phone running software audio codec apps such as Luci Live, CSipSimple, Skype and Comrex VIP QC.

Its ergonomic belt pack design provides a professional look and feel to field reporters and the high-quality microphone preamp and powerful headphone amplifier make sure the message gets through. RemoteMix One plugs into the mobile phone’s headset connector and lets users plug in a broadcast or professional microphone and headphones, both with level controls, plus mix in pre-recorded audio for transmission through the 3.5mm stereo line input jack. In addition to the ¼” stereo headphone jack, the RemoteMix One also has a 3.5mm stereo line output jack that provides full bandwidth microphone signal on the left channel and return audio on the right channel.

Whilst in an ideal world, Bluetooth connectivity to a mobile phone for broadcast would be desirable, in its low-delay two-way “headset mode”, Bluetooth only offers normal telephone quality of 300Hz – 3.4kHz. Using the cabled connection, RemoteMix One offers end-to-end full broadcast audio bandwidth. If the phone is able to run a software codec or provide HD Voice connectivity, audio bandwidth will be limited only by the audio codec (for example 7.5kHz for G.722 or 15kHz for AAC-ELD). Without a codec, like any phone call live interviews are limited to 3.4kHz voice bandwidth back to the station, but still with the huge advantage of being able to plug in a full broadcast microphone and headset.

The stereo output jack allows you to make a full bandwidth recording using an external audio recorder for transfer back at the station or to use a standalone codec. The stereo headphone output gives you a mix of the XLR microphone input, 3.5mm input and return audio. The powerful ½ watt stereo headphone amplifier will also cut through any crowd noise. Connection to the phone is via a dedicated ¼” jack interface and 2.5mm 3-pole or 3.5mm 4-pole adapter cable that “fools” the phone into thinking that a cabled headset is attached.
