Contacta V22 hearing loop driver
The Contacta V22 is part of a range of hearing loop drivers, called the V series. These hearing loop drivers can supply medium to large size hearing loop systems with a signal. The V22 has two balanced microphone inputs and a balanced line input. Euroblock connectors allow for swift installation. The amplifier can be used freestanding as well as inside a 19” rack.The V22 supplies 12 Ampère (RMS) and a voltage of 22 (RMS), making it possible to provide up to 2400 square meters with a signal. This means the amplifier is very suitable for medium to large sized venues and ideal for use in, among others, congress halls and places of worship. The V22 has outstanding Automatic Gain Control, sleep mode and smart self-diagnostics.The device combines Class-D with DSP technology. Thanks to the efficiency of the device, minimal warmth is generated. That’s why there’s no fan required, heat-sinks are used inside the amplifier. The device is also equipped with thermal protection. A powerful processor provides peak performance when needed, producing superior music and speech quality.
Control and configuration
Whilst designing the amplifiers, simplicity and convenience are continuously kept in mind. This makes the V22 easy to control by using the dial on the front or by using the web interface. The adjacent backlit LCD display enables effortless monitoring of the settings during configuration. There is also the possibility to configuration the device by connecting it in the local network. An easy set-up guides you step by step through the configuration.
Design and engineering
When it comes to a hearing loop system, a couple of factors are important in making a system functional. Things like the dimensions of the room in which the system is to be placed and the materials present in the floor, could affect the magnetic field.
