The satellite speakers used Odyssey speakers similar to those in the iMac G3 and feature four drivers. Plug-and-play support for SoundSticks was added in Mac OS 9.0.4 . [ 9 ] SoundSticks were available along with the similarly designed Pro Speakers , which were also designed by Harman Kardon in collaboration with Apple, but were branded as an ...
A home theater in a box (HTIB) is an integrated home theater package which "bundles" together a combination DVD or Blu-ray player, a multi-channel amplifier (which includes a surround sound decoder, a radio tuner, and other features), speaker wires, connection cables, a remote control, a set of five or more surround sound speakers (or more ...
The first 2.1 audio system from Bose to include a DVD player was the "3-2-1", released in 2001. [1] The "3-2-1 GS" model was introduced in 2003, named for its use of Bose "Gemstones" small speakers, which have two drivers pointing forward and one pointing to the side. [2] [3]
In order to achieve both good adjacent channel selectivity and image rejection, the double-conversion receiver uses two intermediate frequencies (IFs). The incoming radio frequency (RF) signal from the antenna is first mixed with a sinusoidal signal from the 1st local oscillator (LO) to give a high 1st IF frequency.
An audio/video receiver (AVR) or a stereo receiver is a consumer electronics component used in a home theater, home audio, or hi-fi system. Its purpose is to receive audio and video signals from a number of sources, and to process them and provide power amplifiers to drive loudspeakers , and/or route the video to displays such as a television ...
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.
Audio from a receiver that is not voted is ignored. Voting comparators in analog FM systems can switch between receivers in tenths- or hundredths-of-a-second, (faster than one syllable). So long as an intelligible signal gets to a single receiver in the system, the repeated audio, or audio sent to the console speaker, would be intelligible.
The receiver must contain a detector to recover the information initially impressed on the radio carrier signal, a process called modulation. [1] Gain is required because the signal intercepted by an antenna will have a very low power level, on the order of picowatts or femtowatts. To produce an audible signal in a pair of headphones requires ...
