Audio-Technica System 10 wireless microphone
|System 10 PRO digital wireless system provides interference-free operation in the 2.4 GHz range with the new wireless ATW-T1006 Boundary and ATW-T1007 Gooseneck|
SYSTEM-10-PRO WIRELESS MICROPHONE
Audio-Technica has released two specialist installation wireless transmitters for the System 10 wireless system. ATW-T1006 boundary microphone and ATW-T1007 desk stand offer wireless solutions where conventional cables are impractical.
The ATW-T1006 boundary microphone/transmitter will pair with any System 10 or System 10 PRO digital wireless receiver to provide rock-solid, 2.4 Ghz wireless performance with clear, natural sound quality. Also the ATW-T1007 is designed to work with phantom-powered, condenser gooseneck microphones the microphone will need to have a 3-pin XLRM-type fitting output, the ATW-T1007 microphone desk stand transmitter and will pair with any System 10 OR System 10 PRO digital wireless receiver.
The durable half-rack chassis is equipped to house two receiver units that can be operated locally or released from the chassis and mounted remotely (up to 328 feet away) via Ethernet cable. Up to five chassis (10 receiver units) can be linked using the RJ12 cable included with each system, creating a stable, multichannel system with the simultaneous use of up to 10 channels.
Like all the products in the System 10 wireless family, the PRO Rack-Mount features 24-bit operation, easy setup, clear, natural sound quality, and three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Space Diversity uses two antennas on each transmitter and receiver unit to maximize signal integrity.
Each System 10 PRO Rack-Mount system includes an ATW-RC13 receiver chassis with rack-mount adapters, one or two ATW-RU13 receiver units with corresponding AT8690 receiver unit mounting brackets, a joining plate (for dual-channel systems only), one RJ12 cable, one AC adapter, and one or two ATW-T1001 UniPakÂ® body-pack or ATW-T1002 handheld transmitters, or one of each. Both the receiver chassis and transmitters feature easy-to-read displays.
Wireless Microphones - The Basics
- Every wireless microphone system must operate on a specific frequency.
- The Australian ACMA government dictates which frequency ranges that can be used by wireless microphones.
- Wireless frequencies are shared with TV stations, communications equipment and a large number of wireless microphone systems.
- Because of frequency sharing, there is always at least a small chance that someone else in the area might be using the same frequency as your wireless system.
- Government regulations also set strict technical requirements for wireless, including limits on maximum transmitter power.
- There must be one transmitter and one receiver to make a complete wireless system, and they both must be on the same frequency.
- If any two transmitters are operating on the same frequency, severe interference will result and the wireless system will be unusable. Two transmitters cannot be used with one receiver at the same time.
- If the frequencies of any two wireless systems are too close together, interference is likely, and one or both systems will probably be unusable.
- The practical maximum operating range of a wireless system will vary from as little as 100 feet (30 m) in heavily crowded indoor situations to approximately 1,000 feet (300 m) under open outdoor conditions.
- Diversity wireless systems will almost always have better operating range than similar non-diversity systems.
- Wireless receivers must have either one or two external antennas, and there should be a clear open-air path between these antennas and the transmitter.
- Weak or worn-out transmitter batteries are a common cause of wireless problems, including complete failure, poor range, distorted audio and interference.
- Use only high-quality alkaline batteries. Most other types of batteries will have much shorter life, and some may cause other problems.
- Because it is easier to accidentally walk near speakers, feedback problems are slightly more common with wireless microphones than with wired microphones.
- The power output of wireless microphone transmitters is very low, and they are completely safe to use. However, any source of RF energy may interfere with the normal functioning of implanted cardiac pacemakers or AICD devices. A body-pack transmitter should not be worn where it is immediately adjacent to such a medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off.
- Take steps to make it less likely that the wireless user will walk in front of the speakers. These steps can include more rehearsal time, markings on the floor, relocation of the speakers and several other options.
- Lower the sound level of the speakers nearest the wireless user and increase the level of other speakers to compensate. If possible, rotate the nearest speakers to point them slightly away from the wireless user.
- Move the microphone closer to the user's lips and lower the transmitter audio gain. This will hold the user's voice at the same level in the sound system while reducing the gain that causes feedback.
- If feedback results from using a body-pack transmitter and an omnidirectional lavalier microphone, change to a directional microphone.
- Try changing to a different type of microphone or microphone capsule. Different microphones vary in characteristics and one particular model might be less prone to feedback in a specific situation.
- Make certain that the transmitter gain is set appropriately for your application. In high-SPL situations, if the transmitter gain is set too high, it may cause overloading of the wireless circuits and increase the chances of feedback.
