ET-501 outdoor speaker adopts waterproof resin shell and stainless steel hanger design, which can adapt to various climates. This all-weather shell is organically combined with high-quality waterproof paper cone speaker, so that it can produce clear and pleasant sound and has extremely high directivity. The factory setting of input impedance is as follows: 16W, 620Ω To change the impedance, use a screwdriver to change the position of the knob on the back cover of the speaker. Note: 1. This speaker uses a 70V/100V constant voltage amplifier, and cannot use an amplifier with low impedance output. 2. When the knob is turned to "OFF", there is no sound output. Note: When using a 100V line, do not turn the knob to the "-" position, otherwise the speaker will be damaged. Specifications:
