Snowflake: The Snowflake is based on Blue's Snowball professional USB microphone. Blue has combined a USB bus-powered capsule with a class compliant design to make the Snowflake plug and play. The mic folds into a single compact case, which also houses a USB cable for easy transport in a laptop bag or even a pocket. Unfolded, the case serves as a desktop stand or a laptop clip.

Automatic Transmission: Ideal for low-power stations, college stations and Internet broadcasting, recordings are simply organized into file folders: a typical installation will have several folders for different types of music, plus folders dedicated to commercials, jingles, weather, etc. A playlist directs the program to randomly select recordings from a particular sequence of folders. Recordings in each folder can be weighted so that some songs or commercials play more often than others. A no-repeat option specifies a minimum amount of time before a recording can play again. In addition to a music rotation, Automatic Transmission can be programmed to play particular recordings at a specified time. It will smoothly transition from a music rotation to timed broadcast, and then back to music rotation. For Internet radio use, the program can broadcast song titles, so the text can be viewed on the listener's computer.



Audio recorder


R-09 HR: With a wider dynamic range, higher bit and sample rates than other recorders, the R-09HR supports up to 24-bit/96kHz linear PCM recording. I.A.R.C. is a newly developed, dedicated analog circuit optimized for recording with the R-09HR's onboard A/D converter. Electrolytic capacitors provide stable, reliable power with an independent power source for the analog circuitry, and another power source for the digital circuit board, thus eliminating dc interference between components in the R-09HR. The I.A.R.C. also contributes to high quality, low noise MP3 recording. When recording, there's no extra equipment to buy or cables to connect. A stereo microphone is built into the unit, complete with a dedicated analog input control, mono/stereo selector, low-cut filter, limiter/AGC and a gain boost. The onboard electret condenser microphone elements are very compact, ultra-sensitive, and placed to capture three-dimensional sound naturally and accurately.


Signal processor



FM2000: Modeled after the Vorsis AP1000 31-band audio processor, the FM2000 includes all of the features of the AP2000 except the digital processing chain with its own dedicated digital output. This product targets customers who seek the performance specifications of the AP2000 but do not require the digital processing chain.



Audio level processing system


Pod Blaster: This entry-level digital audio processor is designed for podcasters, broadcast studios and program production applications, but can also be used for dual microphone level control. It features analog and digital inputs and outputs, GUI set-up via USB and nine pre-set audio profiles. The Pod Blaster produces smooth professional sound, ends listener annoyance and tune-out due to sloppy levels, allows every presenter the freedom to concentrate on the content, improves audibility and clarity of the program and eliminates overload distortion and damage.
