    Brief Description - What is it, and why do I need it?
    These Mixers allows DRAs, SignaLink™ USBs or other sound cards and Pactor Modems (or other modems) to be connected to one radio - at the same time.

    The Mixers are the same with one exception - the radio port connector.
    The DIN6 model has a female Mini-DIN-6 Radio Connector.
    The RJ45 model has a female RJ45 Jack.
    Both Mixers have Mini-DIN-6 female input connectors (SC-1 & SC-2).

    The DIN6 model is great for radios with a matching Mini-DIN-6 Data port.
    The RJ45 model uses radio cables and configuration modules made for the Tigertronics SignaLink™. (Available directly from Tigertronics or an Authorized SignaLink™ Dealer), and works with virtually hundreds of radios.

    The center pin is positive - sleeve is negative.
