    DFINDISTRO4 - Overview

    The RF Venue DISTRO4 distributes diversity RF and DC power across four wireless microphone receivers of any brand. A true "distribution amplifier," DISTRO4 splits signals from two antennas (or one Diversity Fin) connected to the rear panel and amplifies them before delivering the signals to multiple receivers in a rack. An additional cascade port is included for daisy chaining multiple units together to accommodate up to 16 receivers per antenna pair.

    DISTRO4 features a 2000 mA internal power supply (no wall wart) and compares to antenna distributors twice its price. It includes all RF and DC power cables needed to connect a 4 channel wireless microphone system as well as cascade to one additional DISTRO4.

    The DISTRO4 is also sold bundled with a Diversity Fin antenna and coax cables. Replacement power cables are available.

    The patented Diversity Fin is a multi-purpose antenna for wireless microphones that reduces dropouts using a cross-polarized design. It combines one LPDA and one dipole antenna in an orthogonal (right angle) configuration. One element captures vertically polarized waves, and the other horizontally polarized waves-doing the same job as two "shark fin" paddles while greatly improving RF and audio performance.

    To use, just connect both the A and B outputs on any antenna distributor or microphone receiver and point toward the stage.

    The Diversity Fin has found widespread adoption across multiple pro audio segments for its performance, convenience, space, and cost benefits. From high profile live sound events, to film and TV productions, to routine installations in schools and churches, the Diversity Fin is the ideal all-purpose external antenna for diversity microphone systems of any brand. A parts kit is available to replace lost whip antennas and mounting blocks.
