Questions frequently asked
What is the range of the LD Systems U505 BPHH 2 wireless system?
The advertised range exceeds 100 meters in open field. The RF transmission power is selectable between 2, 10, and 30 mW depending on stage conditions.
How many U505 systems can operate simultaneously?
Within the U505 band from 584 to 608 MHz, up to 12 systems can be used at the same time. Automatic scanning facilitates the selection of a free frequency.
What is the battery life with AA batteries?
The transmitter operates with two AA batteries and offers up to 10 hours of advertised battery life.
Does the U505 BPHH 2 protect against radio interference?
The UHF True Diversity architecture is combined with a pilot tone and a squelch circuit. The receiver mutes in the absence of the pilot tone to limit noise from unwanted signals. Infrared sync then allows quick alignment between transmitter and receiver.
What information is displayed on the receiver's screen?
The OLED display shows the group, channel, radio frequency, signal strength, and battery level. User name input is also provided to identify different users.
