Model: Beachtek DXA-SLR MINI
The DXA-SLR MINI provides full audio control and monitoring features for HDSLR cameras and is the ideal interface for wireless audio gear or mics with mini-plug connectors. Has the same great features as its big brother DXA-SLR PRO less the XLR connectors and phantom power features which are not required for these mics.
Allows you to connect and two mono mics for two channel audio or one stereo mic for stereo audio. Low noise preamps provide superb audio with fast acting limiters to reduce the chance of clipping. Easy to read VU meters make setting the proper recording levels a snap while the headphone output lets you monitor audio as you record. A unique AGC Disable feature controls the wild swings of the Auto Gain Control that plague many cameras. This reduces the noise during quiet moments of recording allowing you to record two channels of clean audio.
Fits neatly under any camera and can also be mounted to a tripod. Operates on one 9 volt battery.

And enjoy than the expression of the music by switching the system. It is a high-quality system selector to taste the thrill of such audio. To avoid noise through the ground loop adopts audio quality design grounding switch each circuit. Adopted (99.99997% copper) wire 6N information loss is less pure in the wiring goods, for example, use a gold plated high purity to the terminal, consists of a grade that is comparable to high-end separate amplifier. There is no compromise in consideration of the sound quality.

This breakout for the Silicon Laboratories Si4703 FM tuner chip is a little more stripped down than our FM Tuner Evaluation Board. If your project already has an amp and just needs a full-featured FM tuner, this is the board for you. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.
Using this board we are able to pick up multiple stations just as well as with a standard FM radio. The board breaks out all major pins and makes it easy to incorporate this great chip into your next radio project.
MFJ Enterprises Original MFJ-931 1.8-30 MHz HF Artificial RF Ground.
Create an artificial ground with the MFJ-931! It effectively places your rig near actual earth ground potential even if your rig is on the second floor or higher with no earth ground possible! It electrically places far away RF ground at your rig. Hows your RF ground? Do you have RF "hot spots" that "bite" you when you transmit? Do you have RF feedback that causes your rig to quit working on some bands? Do you have TVI/RFI that makes your neighbors hard to live with? Do you get weak signal reports because of extreme ground losses or radiation pattern distortion? These problems could be caused by poor RF grounding, especially if your rig is on a second floor with no ground at all. Even if you have a good ground, a long connection wire can ruin its effectiveness by isolating a true RF ground from your rig. MFJ-931 creates an artificial RF ground! It resonates a random length of wire thrown along the floor and produces a tuned counterpoise. This ground effectively places your rig near actual earth ground potential even if your rig is on the second floor or higher with no earth ground possible. Also, the MFJ-931 electrically places a far away RF ground directly at your rig -- no matter how far away it is. It reduces the electrical length of the ground connection wire to virtually zero by tuning out its reactance. The MFJ-931 connects between your rig and a random length of wire or a connecting ground wire. Its tuned for maximum ground current using the built-in RF ammeter. The MFJ-931 Artificial RF Ground covers 1.8 - 30 MHz and measures a compact 7.5W x 3.5H x 7D inches.
