OX8

The OX8 takes eight balanced microphone signals and feeds each one to up to three destinations at once, such as a front-of-house console, a monitor console and a recorder or broadcast feed. Transformer isolation on the isolated output, together with ground lift switches, is used to remove hum and buzz caused by ground loops.

Each channel has a balanced input, a direct output that also acts as the return path for 48V phantom power, a thru-put with a ground lift switch, and a fully transformer-isolated output. The signal path is kept very short and RF filters are built in to help in noisy environments. Buyers can choose between two versions: one with premium Jensen JT-MB-CPC transformers (OX8-j) and a lower-cost one with Eclipse ET-MS10 transformers (OX8-r).

Being passive, the unit is connected with ordinary balanced microphone cabling. Several units can be combined to cover 16 or more channels. Typical uses include recording a live show while feeding the PA, isolating front-of-house and monitor consoles, and sending a clean feed to a broadcast truck.
