JBL Professional LSR2300

Studio monitors
JBL Professional
LSR2300: The LSR2300 Series includes the LSR2328P bi-amplified 8" studio monitor with 165W of amplification; the LSR2325P bi-amplified 5" studio monitor with 90W of amplification; and the LSR2310SP powered 10" studio subwoofer with an integrated 180W power amplifier. JBL applied the same stringent linear spatial reference criteria used in the design of the LSR6300 and the LSR4300 Series. Instead of a single on-axis measurement of the speaker's performance, JBL's LSR requires 70 measurements. LSR2300's large waveguide and elliptical tweeter aperture work in conjunction with a 1" silk-substrate high-frequency transducer to deliver superior imaging and smoother frequency response in the control room.

JK Audio Inkeeper LTD

Digital hybrid
JK Audio
Inkeeper LTD: Innkeeper LTD is a desktop digital hybrid providing talk show quality phone connections. This digital hybrid connects audio signals to a standard analog telephone line without the transmit/receive crosstalk common to analog hybrids. Its digital signal processor (DSP) continuously monitors both the phone line and audio signals. This proprietary, dual-convergence echo canceller algorithm can achieve separation typically exceeding 50dB, without any setup and without sending a noise burst down the line. An auxiliary telephone is only required to place outgoing calls. The Remote jack allows connection to a JK Audio Guest Module, for remote control and dialing without an auxiliary telephone.

KRK Systems R6

Passive studio monitor
KRK Systems
R6: The R6 incorporates design cues from KRK's Rokit line, including radically radiused edges along the front of the cabinet. The R6 provides a sleeker, more modern look. A key component to the new look is the molded front baffle. This design feature virtually eliminates diffraction distortion caused by standard flat baffles. The R6 leverages KRK's research and development into baffle design and fabrication. The curved front baffle was engineered to minimize diffraction of high-frequencies, resulting in a sweet spot that is significantly larger than products with square or lightly rounded baffles. The baffle also houses a molded front-facing bass port that minimizes low-frequency phase distortion and unwanted frequency emphasis typical of rear-facing bass ports.

Personal RF safety monitor
LBA Technology
Safe One: Safe One personal RF safety monitors are an effective and economical means to monitor the strength of electromagnetic fields from mobile phone towers, microwave ovens, radio and television installations, high frequency welders, and other common workplace RF sources between 10 and 10,000MHz. The Personal RF Monitor is essential RF safety equipment in complying with FCC, OSHA and other safe workplace requirements. Safe One personal RF safety monitors give you audio and visual warning when the IEEE and ICNIRP limit is exceeded on your body. It immediately alerts you to high frequency radiation fields that could be a health hazard. Safe One gives an approximate value of RF strength to help you determine how long you can stay in the radiation field.

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.
