【Speaker Frequency Divider】This is a professional 2 way crossover that is widely installed in speakers. It plays an important role in full-frequency signal segmentation. Treble and bass dual frequency support, helps to transmit the treble signal to the tweeter unit, and divide the bass signal into subwoofer unit. | 【Treble/Bass Dual Frequency Filter】Make the treble clear and increase the intensity of the bass, freely enjoy clear and natural music.To separate the mixed audio signal into a treble, bass, and then were sent to the corresponding treble, bass speaker unit in playback, resulting in enhance the sound quality purposes. | 【High Quality and Durability】Wire wound ceramic resistor and high-quality metal film capacitors, ensure its large load power, long-term durability, hard to burnout. | 【Reasonable Design】The 2 way frequency divider has large capacity, reasonable design, beautiful appearance, circuit board design with precise cutouts and lines, free for connecting, very suitable for DIY speaker. Widely use in treble and bass speakers, car full frequency speakers, or use treble/ bass alone. | 【Package Contains】2pcs speaker frequency divider. Series: HiFI , 2 way 2 unit (woofer and tweeter); Crossover frequency: 3200Hz; Power: 400W(MAX); Resistance: 4-16 Ohm.

HC-12 Power Supply Voltage: 3.2V~5.5V. (If the module is to be in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the power supply voltage exceeds 4.5V to avoid the built-in LDO heating of the module). | Default Communication Distance(open field test): about 600m (the communication distance can be adjusted up to 1000m, the air baud rate is 5000bps). | Default Idle Current: 16 mA (module operating current is different in different operating modes). | Operating Frequency Range(433.4-473.0MHz, up to 100 communication channels), maximum 100mW transmit power (settable). | Default Factory Setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).
