The UA834 provides more flexibility in wireless installations by increasing the allowable length of cable runs between a receiver and antenna. Antennas may be placed closer to the stage, or installed on ceilings and walls that maintain a better line of sight with the transmitter. Low-noise signal amplifier compensates for insertion loss in coaxial cable. Compatible with Shure Wireless Systems. Also may be used with Shure UA845 and UA844 Antenna Distribution Systems.
Integrated threaded adapter mounts easily to microphone stands or the supplied surface-mount bracket. LED indicator for RF signal overload. Shure quality, ruggedness, and reliability.Antenna amplifiers are intended to compensate for signal loss in cables, not for increasing the range of the antenna. Attempting to "boost" the signal beyond nominal levels only results in overloading the circuit and reducing performance. Indicates it is receiving power from the antenna input on the receiver or combiner. Signal from the antenna at the. Remove the inline amplifier or move it further down the cable run. Set the gain switch to +6 dB for shorter cable runs, and +12 dB for longer runs. RF overload can occur at the input to the inline amplifier or at the input to the receiver. An overload at either point degrades the signal. When there is an RF overload indicator on the inline amplifier, the amplifier might not be necessary, or it should be placed further down the cable run at a midpoint between the antenna and receiver. The gain switch only affects output gain, and cannot compensate for input overload at the amplifier.
If there is an RF overload signal on the receiver, reduce the gain on the inline amplifier, or move it further up the cable run so there is more cable between the receiver and the amplifier. Note that the overload level for the amplifier might be greater than that for the receiver input, so it cannot be used to indicate whether the signal will overload the receiver at that point in the cable run. Connect between the antenna and receiver (or antenna distribution system), as shown. LED illuminates green when the receiver is powered on. Use Shure low-loss coaxial antenna cable or any 50 ohm, low-loss cable.
The quality of the cable, not just the length, contributes to signal loss. A lighter grade 50 foot cable may require more gain than a 100 foot, low-loss cable. Active antennas, such as the UA874, have a built-in amplifier, and may not require additional amplification. Use only Shure antenna accessories to ensure the best operation.
Do not use splitters, combiners, or antennas that provide a DC ground. If necessary, use a BNC DC block device (compatible with the receiver RF band).10 to 15 V DC bias from coaxial connection, 0.60-0.72 W. Input Third-Order Intercept Point (IIP3).
