The Audio-Technica "System 10 Pro" rack-mountable digital wireless system is so simple to use, so dependable and so automatic that you'll never have to think about it. Set it up anywhere, turn it on and its good to go.

Like the rest of the range System 10, the System 10 Pro works in 24-bit / 48 kHz, and allows easy use while ensuring clear and natural sound quality. The system offers three levels of diversity: frequency, time and space. Frequency diversity sends the signal to two frequencies allocated for communication without interference. The time diversity sends the signal in several time slots to optimize immunity against multipath interference. Finally, space diversity uses two antennas on each transmitter and receiver to maximize signal integrity.

The System 10 continuously monitors the activity in the 2.4GHz band and automatically adjusts its own frequencies to avoid interference. Thus, this system works perfectly well in WiFi environments. Also ideal for add channels to an existing installation running on TV frequencies, since the System 10 Pro will not result in intermodulation or interference.

With an RJ12 cable supplied with each system, it is possible to connect up to 5 frames (10 receivers). While many systems can operate without being connected, this is not recommended. Indeed linking the systems to create a more stable environment in which receivers are coordinated for the reception, transmission and frequency allocation avoids signal loss and optimizes the simultaneous use of the 10 channels.

Designed for wind-metal instruments, saxophone and others, the UniMount® ATM350U mounting system offers you the tools to act with confidence. The system includes the ATM350a cardioid condenser microphone, a microphone that supports high levels of sound pressure, and offers a clear and well-balanced response from any instrument. When combined with the universal AT8491U clamp and the flexible, robust and flexible AT8490 5-inch bracket included, the microphone can be securely attached to the instrument strap and placed so that it stays in the place you want - the bracket Flexo type will remain static regardless of what the instrument moves when playing.

The cardioid polar pattern of the microphone isolates the instrument by reducing the pickup of side and rear sounds, and the switchable 80 Hz high pass filter of the online power module helps control noise from unwanted low frequencies. The system also includes a violin holder (AT8468) with velcro fastener and a carrying case.

  • Small sized microphone that goes practically unnoticed
  • Clear, bright and well-balanced response, even at high sound pressure levels
  • Cardioid polar pattern that reduces the acquisition of lateral and posterior sounds, improving the isolation of the desired sound source
  • UniMount® AT8491U universal clamp that securely holds in the instrument's strap and provides excellent microphone anti-vibration protection
