Input 100V black-red, 2 lines, output 8 ohms, black-blue, 2 lines, mainly for public broadcasting accessories, indoor and outdoor sound columns, wall-mounted audio, can also be used as a constant-voltage amplifier audio output , also Is the fixed resistance to constant pressure.
Note: This has a variety of power, please be sure to pay attention to the power you want when placing a buyer's order, the correct choice of the same power color classification orders. Thank you for your cooperation!

Below is a detailed dimensional drawing of 30W:
Tips: 30W audio , used for all ceiling speakers / wall speaker / hanging ball audio / indoor and outdoor sound column need to change the pressure, 4 inch speaker connected to 3.
As long as you are a fixed-resistance (4-8) speaker, you must use this to set the 70-100V variable resistance (4-8) to the speaker.
If your constant pressure horn is broken, you must also replace it with this .
Distinguish between the sound by the amplifier:
If the sound column is broken and silent, separate each speaker cable, use the power amplifier to put the sound, the sound should be adjusted to a small point, directly touch the speaker 2 terminals, such as the speaker can make a sound, the description is good, can not sound the description is bad of.
Replace the speaker, put the sound on the amplifier and connect it to the good speaker through the . If you can see the speaker, you can make a sound. If the speaker does not make a sound, the audio is broken.
