1. What does the tone arm balance of LP phono mean
The tone arm is an important part of the LP phono, which is responsible for keeping the information picked up by the phono on the disc. Passing to the preamp processing, in order for the stylus to pick up the most and most correct signal, the tone arm needs to be balanced. There are two types of tonearm balances for lp phonographs:
1. Static balance
The common tonearms are mostly statically balanced, and the characteristic is the tonearm The rear counterweight is not only used when the tonearm is reset to zero (the two ends of the tonearm are under the same force, balanced, and the needle pressure is also zero), but also the needle pressure is adjusted by using the dial above; in other words, the needle of this tonearm Compression is produced by changing the force on both ends of the tonearm.
2. Dynamic balance
The dynamic balance arm also has a heavy hammer, but it is only used when the tonearm is reset to zero, and its needle pressure is inside the tonearm. The spring control is adjusted by a small dial next to the tonearm.
Since a spring is used for dynamic balance, there is inevitably a problem of spring aging, but the advantage is that it does not care about the level of the turntable; the advantage of a statically balanced tonearm is that the physical characteristics of the weight are almost unchanged (no aging problems), But it is more about the level of the disk.
Second, how to adjust the balance of the tone arm of the vinyl record player
Many friends will ignore the adjustment of the tone arm balance of the LP record player, which will cause the sound to sound like If it is boring and without waves, then it needs to be adjusted. The specific adjustment method is:
1. Support the tonearm
Put the middle of the tonearm Attached to a supported center shaft by a connection like a plastic hook or latch. Support the arm to prevent the stylus from falling into the turntable and strengthen the stable arm.
2. Stabilize the tonearm
Move the balance arm forward and backward along the length of the tone arm until the tone arm and balance arm are free hang in the same horizontal position. Now your tonearm has an optimal tracking weight of 0g. Tighten the lock nut to stop the anti-gravity slip, but not too tight, just not enough to move it with light pressure for fine-tuning.
3. Find the original state of zero weight
Since the tonearm with a weight of 0g is in a very balanced position, you can now find the tonearm Track the weight dial, which is usually located on the back of the tonearm. Set the dial to zero and then confirm your desired weight. NOTE: Not every tonearm has a handy weight dial. Don’t worry if you don’t have a dial, buy a tracking weight scale yourself to achieve the same effect.
4. Control the tonearm weight
If the balancer is on the thread, you can rotate it until you get the desired weight, and of course you can also move it dial. If your tonearm doesn’t have a dial or thread for the weight, put the tracked weight meter on the dial of the turntable and stylus. Move the balancer back and forth to a suitable tracking weight. When you know you’ve found the correct weight, just look down at the reading and record it.
5. Avoid slipping needles
Set the weight of the skid and the tracking weight of the tonearm to the same number. This adds some power to your tonearm and keeps it from sliding out of the grooves of the record. It pulls on the tonearm, effectively balancing the force of the needle in the groove.
