Audio Power Amplifier Design Handbook, 5th Edition

Moving magnet pickups generate a small voltage by moving a magnet between copper coils. MM pickups have a very high inductance and impedance. The Phonos offers a choice of three capacitors to correct the linearity of the frequency and phase response.

The capacitances are pF, pF and pF. In the off-position the capacitance is determined by the capacitance of the cable. The MC pickup is also a small electromagnetic generator, but with the magnets firmly anchored and the coils moving between them, i. The output voltage, however, is very low at only a few hundred microvolts and is therefore more sensitive to noise and induced hum.

This makes preamplifier design a challenge, because the very low output voltage must be pre-amplified extremely noise-free. Phonos offers one of the most powerful phono preamplifiers for MC systems with up to Thanks to the V technology, the preamplifiers are extremely low-noise, linear and phase-locked.

MC pickups have a very low inductance and impedance. This means that the effects of cable capacitance from turntable to preamplifier are negligible.

The impedance, however, is relevant and can be set in six positions: , , , 2. If there is any doubt as to which impedance matches that of the pickup, the impedances can also simply be switched through until the linear frequency response is acoustically determined. With so much sonic quality, the price is well below its musical equivalent.

The pre-amplification can be switched in three values. In the dB position, the phono produces enough output level for normal hi-fi equipment operating at a reference level of dBV. The Phonos offers a switchable subsonic filter to remove this rumble.

With just a few clicks it is tuned to the respective pickup system and then it's ready to go - and how! Gold-plated RCA sockets are available for connecting the turntable and for outputting to a preamplifier such as the Director Mk2 or the Elector. A ground connection for the turntable is designed as banana plug socket. The ground lead can be either clamped or plugged in. The RIAA equalization curves introduced a global de facto industry standard for vinyl records in The high frequencies are boosted by up to 25 dB to increase the signal-to-noise ratio between the noise of the record media to the audio signal.

During playback, exactly the opposite happens in the Phonos. The de-emphasis filter red RIAA curve compensates for the pre-emphasis and the result is a linear frequency response.

Advantages: The capacitors charge and discharge faster, which results in better resolution and faster impulse response.

Moving coil MC phono preamps aka head amps are always a challenge. This is due to the very low output level, typically measured in microvolts. Many people prefer moving coil to moving magnet or moving iron cartridges because of their very low output impedance, which largely negates the effects of cable capacitance. Another benefit is very low inductance, which can cause response anomalies when combined with the cable capacitance. See the article on Cartridge Loading to see why this is important. Many but by no means all MC cartridges also have a lower moving mass, so they can track the vinyl grooves better, especially at high frequencies. With a DC resistance of between ohms, most are designed to operate with a load impedance of 20 ohms or more, and ohms is a 'typical' MC preamp input impedance. This can increase the 'cost of ownership' to the point where it requires great commitment and deep pockets.

As we get older, living with hearing loss becomes more and more likely. Talking to loved ones, watching television, and even listening to the birds outside your window can be difficult for Americans with hearing loss. When purchasing a hearing aid , you have a few different options. First, there are prescription hearing aids, which are regulated by the FDA and require a visit with an audiologist or hearing health professional. While these devices are not designed to compensate for hearing loss, they still offer many people a handy way to hear better.

By Ben Marks — August 5th, Like a lot of adults who attended too many rock concerts in their reckless youth, my hearing is not what it used to be. But I do have trouble hearing someone speaking to me in a crowded restaurant, and certain sounds with the wrong acoustic profile for me, anyway will make my ears ring for hours.
