Some musicians need freedom when playing their instrument, and with the U-Series Wireless Instrument System, they may have all the freedom they like. Simply attach the wireless transmitter to your instrument and you're free to play for up to 12 hours on a single AAA battery. The solid base receiver can run on batteries or AC power, allowing for virtually unlimited placement options. Also, the diversity receiver design helps avoid signal drop-outs for greater reliability. Since there are 16 user-selectable operating frequencies, up to four systems can be used simultaneously.

Microphone Specifications

Microphone Type
This is the type of microphone included with the purchase of the item.

Wireless:All of these microphones can be used without the necessity of wires or cables to connect them. They usually come with a receiver that connects to the input device where the audio signal is being sent.

Shotgun: These microphones are suspended on a boom and are used primarily in video production and broadcasting.

Lavaliere: These microphones are clipped on to the lapel or tie of the talent for broadcast and video production audio.

Table Top: These microphones are designed with a built in stand or to be placed on a table top stand to be used for broadcasting and podcasting applications.

Headset: These microphones are to be worn on the head typically for live performance and theater production.

Handheld: These microphones are held in the hand and are used in a wide range of applications primarily vocals and public address.

Clamp On: These microphones attach directly on to an instrument.

Drum Package: These microphones are an all in one package for drums typically made of dynamic Kick, Snare, Tom, and a stereo condenser pair of overhead mics for Cymbals.

Clamp On
Designed Applications
The intended application the microphone is designed for.
Number of Microphones
This is the number of microphones that are included in the package.
Polar Patterns
The polar pattern of a microphone determines how sensitive it is to receiving sounds as they arrive at different angles.
Transducer Type
The transducer type is the manner in which the audio signal is converted into an electrical signal.
The configuration of the capsule determining on which side the microphone is sung or spoken into.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
50 - 20000 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
95 dB
Output Impedance
This is the amount of impedance that the microphone allows.
5-10 k ohms
A pad is a term used for built in attenuation in a microphone or pro audio channel strip.
Power Requirement
Condenser microphones require an external power source to operate. Typically a +48v DC charge commonly refereed to as Phantom Power.
Connection Type
This is the manner in which the microphone connects to the source unit. For wired microphones, this is the connector that directly connects the microphone to the mixer (or other input source unit). For wireless microphones, this is the connection that connects the microphones receiver to the mixer (or other input source unit).
1/4" (TS Connector)

Wireless Specifications

Carrier Frequency Range
The frequencies of radio waves used by wireless communication transmitters and receivers. VHF 30 to 300 MHz, wave length 1 to 10 m UHF 300 to 3000 MHz, wave length 10 to 100 cm
900 - 925 MHz
Operating Range
The maximum span of distance between The Transmitter and Receiver.
328 feet
Number of Channels
The number of different frequency Channels that a wireless microphone system is capable of using.
Transmitter Type
The type of transmitter in a wireless microphone system.
Receiver Type
The type of receiver used in a wireless microphone system.
True Diversity receivers have two radio modules and two antennas. Diversity receivers have one radio module and two antennas, although some times the second antenna may not be obviously visible. Non-diversity receivers have only one antenna.
