Sistema UHF PLL wireless, diversity a doppio canale
Sistema UHF PLL, con trasmissione diversity, composto da: 2 radiomicrofoni a mano con trasmettitore MH-920, 1 ricevitore con due canali US-902D con 16 canali selezionabili. Banda di frequenza 720 MHz - 744 MHz.
US-902D
* 16 selectable, preset UHF channels.
* Diversity technology minimizes dropouts in the RF link.
* Noise mute and pilot tone squelch.
* Equipped with both XLR balanced and Ø6.3mm unbalanced outputs.
* Metal housing fits this dual channel receiver into one rack space.
Mh-920
* 16 Selectable channels.
* Phase-locked Loop (PLL) synthesized tuner.
* Advanced circuit design ensures stable signal transmission.
* Extended dynamic range and smooth frequency response.
* Noise mute and tone-key squelch.
* Internal antenna design benefits unique styling.
* The “lock-on” function prevents tampering and RF interruption.
