Furthermore, the number of microphones can be easily expanded when needed by simply powering on more microphone transmitters, significantly improving usability of the system. ULX-D has overcome the university’s past radio interference issues and now provides stable wireless performance in the conference room. 2 UA864A Directional Antennas were mounted on the ceiling at opposite ends of the room, enabling continuous use of the wireless system when room partitions are being moved to expand the space. 4 ULXD4Q Quad Channel Receivers were installed in the equipment rack in the room, paired with 16 ULXD2/SM58 Handheld Transmitters. The Shure ULX-D Digital Wireless System delivered the best performance and was ultimately chosen. Solutionĭenshi System Co., Ltd., a system integrator used by Meisei University, conducted an RF spectrum scan on-site and extensively tested several wireless system options. The university was looking to resolve the problem of radio interference and be able to efficiently operate 16 wireless microphones simultaneously. However, this meant that no more than one person could speak at a time, in addition to the extra setup time that was required. The university previously accommodated this by bringing in more handheld microphone transmitters and assigning them to the same wireless channel.
Larger meetings may sometimes require up to 16 microphones. In addition to the wireless performance, scalability was also a problem. Nearby mobile phone base stations further worsen the spectrum environment. Old and new equipment co-exist, often with overlapping frequency bands, and prolonged periods of use causing interference. Over the years, a growing number of AV equipment was installed throughout the campus, with more than 50 wireless microphones in operation in and around the Administration Building. Radio interference has become a frequent problem and interrupted meetings. The medium-sized multi-purpose space has a maximum capacity of 50 people and is used for general and department meetings, ceremonies at the beginning of the academic year, faculty and staff training, as well as important Dean and faculty meetings. ChallengeĬonference room 701B, located on the seventh floor of the Administration Building, is one of the most frequently used rooms in the building. It is known for incorporating practice-based, hands-on learning in their courses from early on and developing individual students’ abilities through a cross-departmental curriculum. With approximately 8,000 students attending the vast campus in Hino, Tokyo, the university also offers distance learning courses and graduate schools. Throughout our testing, we were constantly and pleasantly surprised by the way it handled itself.Founded in 1964, Meisei University has a total of 9 schools and 12 departments. For heavyweight audio editing, it's not as feature-packed as the likes of WaveLab, but then it's nowhere near as expensive. On the downside, although you get peak/RMS metering, there are no built-in spectral analysis tools.ĭSP-Quattro gets a big thumbs-up for its routing flexibility and virtual instrument support, going beyond your basic audio editor in that sense. Basic audio editing and looping is easily applied, and with audio scrub, you can even find your edit points by ear if you like. The onboard effects do the job, although for serious mastering, you'll be glad of the AU/VST support. It makes it easy to put together a CD master, with crossfades, ISRCs and track- by-track and global insert processing.
Once you've found a setup that works, use it as a template.ĭespite being quite 'different', DSP-Quattro is admirably self-explanatory in many respects, and the precise yet stylish Logic-style graphics feel instantly familiar. Ultimately, we'd prefer a global workspace-based layout rather than DSP-Quattro's 'start from scratch with each new file' approach, but the Project file type does recall your exact window layout. On paper, this might all sound slightly odd, but it's an extremely flexible system, and with four internal stereo channels and hardware routing built into many of the modules, creative routing setups can be built to an extent that we've not seen in an audio editor before. You can freely arrange all of these and hide, deactivate and generally organise stuff in the Documents window, which lists all of the active Generators. These include the Input, Input Recorder, Virtual Instrument and Audio File Player modules, which feed into the Audio Output and Output Recorder modules. The main thing you should understand about DSP-Quattro is that it's a modular system, with sound-producing modules called Audio Generators.
