SHUREULXD2/N8SB-G51Handheld

The Shure ULXD2/N8SB-G51 is a ULX-D digital handheld transmitter fitted with the Nexadyne 8/S supercardioid dynamic wireless capsule (black, RPW204) on frequency band G51 (470-534 MHz). It is not a KSM11, SM58 or Beta capsule configuration.

Key Features

• ULXD2 handheld digital transmitter; machined aluminium housing
• Nexadyne 8/S (NXN8/S) supercardioid dynamic capsule with Revonic dual-engine technology - wireless black capsule RPW204
• Band G51: 470-534 MHz; selectable RF power 1 / 10 / 20 mW (region dependent)
• Shure SB900-series Li-Ion or AA batteries; >11 hours typical with SB900C @ 10 mW
• Mic offset 0 to 21 dB in 3 dB steps; integrated single-band helical antenna
• Works with ULX-D receivers (system latency <2.9 ms; RF sensitivity −98 dBm at 10−5 BER)
