Q: 7. Is this cartridge fully capable of playing CD-4, QS, SQ, and other 4 channel quadraphonic records?

A: This phono cartridge cannot be used for this type of multi-4 channel vinyl record; playback: Phono cartridges with very high frequency range were rare in the 1970s but became much more common in later years. Only through the use of an elliptical tip stylus is the cartridge able to accurately reproduce the necessary extended range. This stylus is usually marketed as a "Shibata", "Line Contact" or "Micro Ridge" type. By contrast, a standard conical or cone shape stylus has less contact area with the record groove. CD-4 playback in 4 channels also requires a specialized CD-4 demodulator. Such demodulators have not been sold commercially since the 1970s. These were often built as independent components. However, some audio receivers and or amplifiers built in the 1970s included the CD-4 demodulator as a built-in feature, along with FM radio and amplifier circuitry. The sum of the front and rear signals are combined on each wall of the record grove, then a very high frequency carrier level is applied which contains the difference signal. This signal starts at 30,000 cycles and extends up near 50,000 cycles. When played on a regular stereo, these discs sound normal (hence compatible), but to hear the quad separation, the signal must be demodulated. A typical high-performance CD-4 system would include a turntable with a CD-4 compatible phono cartridge, a CD-4 demodulator, a four-channel amplifier (or receiver), and four identical full-range loudspeakers.[4] CD-4 encoded records were also compatible with conventional two-channel stereo playback systems. In stereo mode all four channels of music can be heard over two speakers. Specialized equipment is not required for stereo playback.

Q: 10. Do they offer a Flat response throughout the frequency, similar to ATH-40X or are not so good for Audio Editing? Thanks

A: The Audio-Technica Consumer ATH-M50xBT2 Wireless Over-Ear Headphones with Bluetooth sound very much like the wired version - the Audio-Technica ATH-M50x Closed-Back Monitor Headphones (B&H # AUATHM50XB) which are often purchased for editing. The overall frequency response of the ATH-M50xBT and the ATH-M40x is fairly flat and both have a slight boost in the low frequencies. When compared to the ATH-M40x, the ATH-50x and ATH-M50xBT both have more highs
