Jasmine Audio JS-TAAB Air Bearing Tone Arm

Design philosophy of vertical arm bearings with two springs

The anti-vibration design of the tone arm requires consideration of two main aspects. One is measures against the resonance that stylus occurs during tracking. In order to effectively attenuate and absorb this resonance, it is necessary to use an anti-vibration material in the structure of the front of the tone arm and a coupling mechanism with excellent vibration resistance. The other is measures against vibrations transmitted from the turntable. The upper and lower interference vibrations at the bearing of the tone arm are filtered and absorbed by the spring mechanism.

Many tone arms focus only on the resonance measures of the former and tend to neglect the vibrations from the turntable. However, the sound of the analog record is played by the stylus detecting the vibration of the groove, and interference from the outside that is unrelated to the groove should be blocked and separated as much as possible.
By eliminating this unnecessary vibration, it is possible to draw pure sound for the first time.

Bringing together advanced technologies

The JS-TAAB Air Bearing Tangent Tone Arm combines advanced materials and technology to deliver a vast sound stage, silent background and powerful dynamics. It traces the audio signal from the sound groove of the analog record extremely accurately.
Audio enthusiasts will be indispensable to pursuing the best record playback experience.

Nanometer Material Air Bearing

JS-TAAB Air Bearing Tangent Tone Arm is a tone arm developed by Jasmine Audio. Air bushings are made of nanometer material, providing high air pressure and excellent load resistance. This technology is an innovative product in China and is patented by Jasmine Audio.

High Pressure Nanometer Air Bearing

The air bearing ensures the best possible tracking accuracy with smooth friction-free operation and high precision positioning. The gap between the shaft and the bearing is limited to only 5 microns, which realizes a high rigidity and low friction structure that can withstand loads of more than 10 kg.

This bearing mechanism suppresses unnecessary vibration of the cartridge and movement in unintended directions, allowing the stylus to accurately read only pure music signals from the record groove.

Dual Carbon Tube

JS-TAAB Air Bearing Tangent Tone Arm uses two carbon tubes for each signal channel, improves S/N ratio, avoids signal interference on left and right channels, and improves sound quality on analog systems.

The installation is finally completed. The attachment of the cartridge could be mounted with the arm raised above without weights attached. The level of the base is adjusted as precisely as possible with a level instrument. The position of the arm is fixed so that the needle tip of the cartridge is at the center of the shaft of the turntable, and the needle pressure of 2g is applied with the needle pressure gauge. Two weights were attached, so it was balanced in the center so that it was easy to balance, but it did not move well. I thought that the air pressure was not enough, but it jumped. Looking at the theory, I realized that only one balance weight was used. If one weight is set to one, it is possible to achieve a zero balance in the DL-103. So it worked out. The sound of the pump is almost silent even if it is placed nearby. When I entered the inner circle, the sound jumped again. If I fix the lead line song, it became no problem. The sound that is played is totally unwavering that I have never heard before. It is not an easy-to-use arm, but it is recommended for those who want the best sound.* Bakoon Products Nagai Representative Facebook excerpt

JS-TABB is a linear tracking arm using air bearings. It is a product that realizes linear tracking by floating the air bearing with the arm in the air by sending high pressure air to the air bearing with the pump and eliminating friction. With this tone arm, you can get a sharper sound with higher resolution, but the adjustment is more serious. If the adjustment is not done accurately, even the arm operation becomes impossible. First, attach the cartridge to the arm to determine the position of the arm. Adjust the cartridge stylus to come to the center of the turntable spindle. You can also adjust using the included jig. Connect the arm and pump with the attached pipe. Turn on the pump and release the pump position to the position where the pump noise is not heard. The noise of the pump is quiet, but it can be heard slightly when you listen in a quiet state, so you can not hear it if you leave a few meters. Use the arm as the base position to check the shaft level of the air bearing. Since the horizontal part of this shaft is the most important element in normal operation of this arm, it is precisely adjusted using a sensitive level device. If the base of the turntable is horizontal, it is okay, but there is a possibility that it will not move if the horizontal is crazy even a little, so adjust the horizontal of the shaft precisely. Moving the arm by hand does not work properly. The gap between the air bearing and the shaft is only 5 microns, so if you move by hand or excessive force is added, you will contact it. Therefore, when moving the arm by hand, it is careful not to add excessive force. Next, add the needle pressure to the attached cartridge. Needle pressure meter is required to apply needle pressure. It is a lateral balance, but because the scale of the needle pressure is not written on the weight. Next, use a commercial jig to adjust the height of the arm so that the cartridge is horizontal by lowering it to a stationary record. At this time, the air pipe and signal cable connected to the arm and the body are adjusted to the mountain as shown in the instruction manual. This cable and pipe interfere with moving air bearings. Therefore, the distance from the center of the turntable of the arm and the shape of the cable bend greatly affect the operation. These fine adjustmentsTry the code and adjust it so that one side can play smoothly. Therefore, it requires patience to operate without problems. However, the quality of sound obtained from this arm is tremendous. It makes me forget the time-consuming adjustment.Bakoon Products Nagai
