Spectera SEK (1G4)

Article No. 509163

Each bidirectional Spectera SEK body pack manages both an IEM/IFB and a mic/line stream simultaneously.

Plus, they allow for full remote control and monitoring, via identical RF connection, of IEM volume, audio level and settings, RF health, battery status, and more via LinkDesk software. Variants include UHF (470–608 MHz and 630–698 MHz) or 1G4 (1350–1400 MHz and 1435–1525 MHz).

Spectera SEK body packs feature an impedance matching high-power headphone amplifier and offer up to seven hours of operating time depending on the selected Audio Link mode and settings with rechargeable lithium-ion battery BA 70.
