Musicam USA MAT1

Stereo Matching Unit
Musicam USA
MAT1: The Musicam USA MAT1 translates between the low-level, unbalanced signals used by domestic and semi-professional equipment and the more robust, balanced format used in the professional environment. It is therefore the ideal solution to the common studio problem of interfacing inexpensive record/replay units to professional mixing consoles and other balanced equipment.

Nagra LB

Two-channel recorder
Nagra LB: Compact and versatile, the Nagra LB is a two-track recorder. It is a 16/24-bit device with an Ethernet connection and Bluetooth communication. Sampling frequencies of up to 192kHz are available depending on the application desired. This portable recorder can record and edit the material in the field and return it to the studio over the GSM network by means of the Bluetooth communication with a mobile phone. It can be connected directly to the Internet through its Ethernet port. Files can be immediately transferred over IP, representing an easy way of putting music and other recordings onto the Web. The microphone inputs are fitted with a special integrated vortex filter to virtually eliminate wind noise. They are equipped with linkable audio limiters, +48V phantom powering and independent sensitivity selection switches. An AES digital input can also be fed to a dedicated XLR connector.

Nott Ltd. Copperweld

Grounding wire
Nott Ltd.
Copperweld: Nott now distributes Copperweld grounding wire. This wire has been used by the electric utility industry for many years and just now comes to broadcasting. Standard Copperweld wire is not annealed, making it very springy. However, their ground wire is annealed and handles just like pure copper wire. It can also be silver soldered like pure copper. Tests indicate erosion may occur at the ends of buried wires, but will go no more than two wire diameters into the metal. In the case of #10 wire, this is less than 1/4". RF current travels only on the outer surface of a wire due to skin effect, so most of the current will be flowing in the copper skin. Bending it into a sharp radius does not cause the copper skin to crack. Wrap it as tightly as needed, then silver-solder it.

In-line audio VU meter, balanced
Ocean Matrix
OMX-INVU1: OMX-INVU1 is a dual-channel, balanced, line-level audio VU meter with XLR input and outputs. XLR to TRS adapters are provided for 1/4" phone (TRS) applications. 12Vdc powered with a provided 110-220Vac adaptor. The unit may also be battery powered.


OMB America MRI 15

Portable transmitter
OMB America
MRI 15: The MRI 15 is made of a four-audio-channel mixer and an externally synthesized FM transmitter that can provide a 15W RF output signal. This unit has been designed to be used as emergency radio station, really easy to use and to install. It can also be used as a small radio station in rural areas, or even as an exciter of a more powerful transmitter. On its LCD Display, transmission parameters like forward power, reflected power and FM-band modulation level (in 10kHz steps) can be visualized. The MRI 15 works with internal or external 12Vdc power supply, or with ac power supply between 110 and 220Vac.
