JuicedLink Riggy-Assist Dual-XLR Preamplifier with Phantom Power and Metering, 20 Hz to 20 kHz Frequency Response Details


The Riggy-Assist incorporates Audio Output Bracketing (patent pending) for camera overload protection. All of the microphone signals are combined, and sent to the left output channel. An additional copy is sent to the right output channel, but at safe lower signal level (about 16dB lower). So, if you blow out the main audio channel, you have a back up that you can pull from in post. The Riggy-Assist uses a 9V battery, and is a high-current device when all of the elements are in operation (phantom power, meter, etc). However, the Riggy-Assist has a number of features to allow you to optimize your battery life. Portions of the preamp can be selectively powered down if not being used (patent pending), to reduce the current and extend the battery life. If you are doing a fair amount of running-gunning with only one mic, you can power down 1 of the XLR channels (patent pending). If you are using a camera that has meters visible while recording, you can power down the meter (patent pending). Additionally, many modern mics will run down to 12V phantom power, so phantom power is selectable between 48V or 12V. The low-battery indicator can be switched between alkaline or lithium-polymer threshold. Now, the Riggy-Micro series of preamps (RM222) will get considerably longer battery life, as it does not have the headphone, meter, or AGC Disable circuitry (and, it will be smaller and lighter). The Riggy-Assist is designed to be used with cameras which do not have manual control, meters, or headphones. The preamp adds AGC Disable, meters, and headphones that are missing in the camera. If your camera already has those features, then check out the Riggy-Micro line of preamps. The Riggy-Assist can also be used as a XLR front end to digital audio recorders.
