Bi-amping is the use of two channels of amplification to power each loudspeaker within an audio system. Tri-amping is the practice of connecting three channels of amplification to a loudspeaker unit: one to power the bass driver ( woofer ), one to power the mid-range and the third to power the treble driver ( tweeter ).
Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
HP-97 calculator. In 1977, HP introduced an extended version of the desktop model as the HP-97S which featured an extra parallel I/O port (40 lines for 10 4-bit BCD digits, plus 5 control lines) for collecting data from external hardware, [ 6 ] at a price of $1,375.
The article describes active loudspeaker systems. In audiophile circles though, bi- or tri-amping refers to the act of hooking up multiple amps to the individual binding posts of a passive speaker where each amp and speaker terminal receives the full signal and the passive crossover still does what it always does.
ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is Commercial Building Telecommunications Cabling Standard and is published by the Telecommunications Industry Association (TIA), a body accredited by the American National Standards Institute (ANSI).
TI utilized the CC-40 Plus ROM to create the TI-74's BIOS; it removed the CC-40's internal debugger to gain enough space to add calculator mode to the TI-74. The CC-40 Plus' cassette routines were reused in the TI-74, and the CC-40's Hexbus port underwent a physical footprint change and was renamed to Dockbus.
An audio multicore cable and accompanying stage box. Multicore cables can be used for analog and digital signals as well as power distribution. They are often used to simplify the physical setup of a system and provide a neater connection between two pieces of equipment. [9]
Along with the HP 15C and the HP 48, it is widely considered the greatest calculator ever designed for engineers, scientists, and surveyors. It has advanced functions suitable for applications in mathematics , linear algebra , physics , statistical analysis , numerical analysis , computer science , and others.
