(2) Sony MDS JB940 Mini Disc Recorder/player  (Back up System)
MiniDisc (MD) is a disc-based data storage device for storing any kind of data, usually audio. The technology was announced by Sony in 1991. MD Data, a version for storing computer data was announced by Sony in 1993, but it never gained significant ground, so today MDs are used primarily for digital audio storage.
So what exactly is a mini disc? The audio on a MiniDisc is compressed using the ATRAC format (Adaptive TRansform Acoustic Coding) while a CD contains 16 bit linear PCM audio. ATRAC is similar to other compression formats in that data are discarded according to an algorithm that exploits certain psychoacoustic principles. This is known as lossy compression. Due to limitations in human hearing and perception, some sounds cannot be heard under a variety of conditions, and these data can simply be thrown away without noticeable difference to the recording. Whilst the difference in sound quality could be easily spotted when MiniDisc appeared, today it is virtually impossible to tell, due to vast improvements in the ATRAC algorithm. The latest version of Sony's ATRAC is "ATRAC DSP Type S" (Sharp and Panasonic have their own (but fully interoperable) ATRAC codecs).
MiniDisc has an advantageous feature that prevents disc skipping. Older CD players had once been a source of annoyance to users as they were prone to mistracking due to vibration and shock. MiniDisc solved this problem by reading the data into a memory buffer at a higher speed than was required (the size of the buffer varies from model to model) before being read out to the digital-to-analog converter at the standard rate required by the format. If the MiniDisc player was bumped, playback could continue unimpeded while the laser repositioned itself to continue reading data from the disc. If the memory buffer is sufficiently full, this feature allows the player to stop the spindle motor for long periods, increasing battery life. The memory buffer concept was incorporated shortly afterwards into portable CD players.

QSC RMX1450 Power Amplifier
RMX amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling us to pack up to 2400 watts of power!

Monster Cables
Engineered for Better Sound: While other cables can smother sound, increase distortion and flatten bass, link® cables utilize unique patented technologies such as multi-gauge Bandwidth Balanced® wire networks and Time Correct® windings to transfer complex music signals between components with greater accuracy and per phase alignment. Monster's MicroFiber® dielectric employs an intricate cess of winding an air-core fiber around each individual conductor to reduce dielectric losses and electromagnetic distortions. MicroFiber increases dynamic range, extending high frequencies and reducing background noise. In addition, Monster's MultiTwistT construction, ultra-dense shielding and conductive polymer dielectrics are used to eliminate hum, interference and handling noise. Wider frequency response and more natural reduction of harmonics are just some of the improvements musicians discover with Monster Cable link microphone and studio interconnect cables.
