www.xeport.com - Make sure that before you use this clip to test your earphones or loudspeakers, turn the volume of your system down and then gradually increase the setting to a comfortable level. When you listen to music or other audio signals, there are four major parts that are important to your listening experience; 1. The source - mainly the original recording either in analog or digital format. This sound clip is produced with 44.1kHz sampling rate and set to -16dB full scale in stereo PCM format. 2. The playing system - you could use portable music players or a CD players plus pre amplifiers. Most of time, the differences among the audio system are very minimal except poorly made products. 3. Earphone or loudspeaker - this part of the chain is very critical since a audio transducer is like a music instrument. variations in design and production could make a profound difference in sound quality. many people invest hundreds or thousands of dollars in music players and albums while use low quality earphones which in turn wastes the valuable investment all together. 4. Your ear - each individual has different hearing abilities. As people aging over time, most people would experience some degree of hearing loss in terms of sound level and sound frequency range. What to listen for: 1. Frequency Range - This audio clip is produced from 20Hz to 20kHz. You could test your hearing range in frequency domain. 2. Earphone balance - The sound image should be in the middle all ...

McIntosh features legendary 2000 Watt MC2KW Power Amp with patented Quad Balancing Tech
McIntosh features legendary 2000 Watt MC2KW Power Amp with patented Quad Balancing Tech Tube. Duration : 7.07 Mins.
Ken Zelin, International Training Manager at McIntosh Labs introduces McIntosh's new patented quad balancing technology to achieve greater dynamic range in their high end amplifiers. The dynamic range is defined as the difference between how quietly and how loudly a system can play. Larger amplifiers tend to produce more signal ënoise due to the higher number of transistors. McIntosh have solved this problem by ëflipping the noise signal and combining it with the original, thereby eliminating it. The result is an astonishing signal to noise ratio of 129Db. Finally we get to see the technology inside a 2 channel controller with Ruthenium contacts similar to those used in nuclear reactors.
