AT33xMONO/I

The latest update to the venerable AT33 Series – the first extensive overhaul in years – brings new warmth and fullness to your favorite music. Incorporating technological and material improvements, including our first use of die-cast zinc at the base of the cartridge to ward off unwanted resonance and improve expressiveness in the mid to low frequencies, the AT33x Series cartridges let you hear the finest details across the audio spectrum.

The AT33xMONO/I features a “True Mono” dual moving coil design that is unaffected by any vertical noise components picked up from the record groove, instead generating electrical signal only from horizontal movement. This results in exceptionally clear monaural sound with a more substantial low end and reduced surface noise. The dual mono coil design is also ideal for mono playback on a stereo system.

To further enhance its monaural performance, the cartridge is equipped with a 0.65 mil conical nude stylus, which is perfect for tracking the constant width and depth of mono record grooves. Our newly developed suspension mechanism uses piano wire for even more tracking accuracy, lowering the dynamic compliance slightly for more substantial audio, particularly in the mid-low range. 

The cartridge’s composite body, made of die-cast zinc, aluminum, and high-rigidity polymer, reduces and disperses resonance across the entire body, resulting in balanced, natural sound reproduction that doesn’t favor particular frequencies. PCOCC (Pure Copper by Ohno Continuous Casting) coils ensure pure, smooth signal transmission, while the neodymium magnet and permendur yoke (shaped for optimal monaural sound reproduction) create a strong magnetic field that maximizes power generation efficiency, resulting in responsive, high-resolution analog playback.

Like all AT33x Series cartridges, the body of the AT33xMONO/I includes threaded holes for easy mounting (just two screws required). These threaded holes are especially useful when mounting the cartridge to an integrated tonearm. 

Please Note: AT33xMONO/I’s stylus assembly is not field-replaceable, but Audio-Technica offers a fee-based Moving Coil Exchange Program to properly service your moving coil cartridge.

Excellent build quality and thick chrome, strong threaded screw
Color: Silver
I purchased this as a gift for a friend that had problems with wine corks being broken and left inside the bottle. The intention was to have this longer tapered screw extend all the way beyond the bottom of the cork to pull out the entire cork without leaving pieces inside the bottle. One detail that is missing from the instructions is the secret to how a wine cork remover must be used to insure success. The tapered screw must be twisted many turns, which will raise the two lever arms directly upwards away from the bottle. It is critical that you keep turning the screw and remove the metal or paper seal that is on the outside of the bottle before you stop turning. By looking at the bottom of the cork inside the bottle, you can watch the end of the tapered screw appear as it is turned deep inside the cork, beyond the bottom of the cork. Once you have visual verification that the screw is all the way in, notice the appearance of the TOP of the screw outside the cork. You will see that it appears to have been turned very far, potentially damaged the outer surface of the cork. That is a GOOD sign that you used enough rotations of the screw to correctly engage the entire cork. Never skip these steps before you proceed to remove the cork. When the screw is in the correct position, the two levers are all the way up. It may take some force to push them down, so put the wine bottle in a SINK, not a countertop. This lowers the bottle for easier access and gives you a safe place to put the cork remover after you open the bottle. Using a controlled force with both hands, move both levers down carefully to make sure that you do not deflect the tapered screw in a way that is misaligned with the neck of the bottle. As the cork is removed, the last part may be fragile from contact with the wine. In addition, the entire cork remover becomes less stable, and free to pivot if you are not careful. This last motion can still damage a cork and create fragments, so just be careful and precise to gently pivot the levers all the way down and then if necessary use a twisting motion to ease the last part of the cork out of the bottle. This method has never failed to remove hundreds of corks from bottles made all over the world without wrecking the cork. Try it and you will never have a broken cork problem again.
