The connection joint between Roland electronic drum and speaker is unstable for the following reasons:
1. The signal line is broken. Solution: Replace the new signal wire. Only use emery cloth to light the lotus plug behind the speaker and try to plug it back in.
2, dirt blockage, affecting the sound quality of the speaker. Solution: Wipe it with a cotton swab dipped in a little alcohol, and be careful not to wet the inside of the machine (note: it is best to choose anhydrous alcohol instead of medical alcohol for cleaning). At the same time, you can start the cold air mode with a hair dryer, aim your head at the interface, and clean the interface with strong wind.
3, socket damage, solution: If it is not dirt blockage, but socket damage, socket damage can only be repaired by a sound maintenance master or directly replaced with new parts.
The electric drum must have its own power cord, 3.5 small audio jack cord and power cord, so that the electric drum can be connected to the power supply, and then one end is inserted into the sound source hole of the electric drum, and the other end is inserted into the external audio hole.
Can electronic drums use ordinary speakers?
Electronic drums can use ordinary speakers.
Roland's TD9 can be used directly with DVD speakers. Pay attention to the connecting cable or adapter plug, and also pay attention to the volume. The upper and lower limits of household boxes are not as good as those of professional boxes, and the power is much smaller than that of professional audio, so try not to distort the sound, or the speaker will be broken in a few days.
The professional electronic drum speaker belongs to a special vocal cord speaker, and the bass system is specially strengthened. Generally, the double bass or reflected bass structure is adopted to weaken the ultra-high frequency band (that is, the frequency above 14khz). So the effect of ordinary speakers is not necessarily good. If funds permit, you'd better buy a professional one.
Extended data
Drum is a full-frequency musical instrument, which needs special monitoring. Moreover, the sound box is no different from any shock absorption measures for playing electric drums in apartments. Therefore, speakers are not recommended unless they are in the basement of the villa.
The sound box can theoretically meet the needs of electric drums;
1. Drum is a dynamic musical instrument, especially if you want to hear satisfactory and powerful bottom drum sound, you must have enough strength (strength index) and bass diving ability (paper basin size).
2. Drum is a full-frequency musical instrument, so it must be full-frequency for speakers. For this feature, bass speakers and guitar speakers do not need to be considered at all, or they can be ignored.
3. No matter whether the drum is stereo or mono, the stereo is better before installing a pair of M50w, and the directivity of the left and right speakers is too obvious.
How about the low-frequency sound quality of Walter's drum set speaker?
Not bad.
Walter's electronic drum speaker has a good sound quality, which sounds quite good, and there is no noisy mixing.
