Description: Crystal Radio Audio Signal Amplifier For Mono Headset, Speaker or Non-Piezo Magnetic Earphone or EarbudAllows you to use Non-Piezo Earphone, Speaker or Headsets with your Crystal RadioFor Crystal Radio use: Connect the Radio Audio Output to the Input Terminals of the AmplifierWiring Diagram image has a Green connector, you will receive Blue Connector Device.Gain is controlled by Resistor R1 on the PC Board and is factory set at Zero Ohms for a gain of 200.The Gain is controlled by Resistor R1 and is factory set at Zero Ohms for a gain of 200.They operate at 5V – 12V and provide approximately 250mw-700mW of power. The higher the operating voltage, the higher the maximum amount of power that it can provide. The output can drive loads from 4 to 32 ohms. The lower the resistance of the load, the more power it can provide, so a 4 ohm speaker will be about twice as loud as an 8 ohm speaker.Since an LM386 does not provide any overcurrent protection. if you overdrive the output, you will blow the chip in short time.This Listing is for One Amplifier and One Double Ended Connection Cable Caution: Repetitive flexing of the wires can damage any wire and cable systems.It is a good practice to enclose the Amplifier and speaker inside a project box to minimize flexing of the wires as repeated flexing and bending of the wires will cause pre-mature breaking of the wires.CONNECTION DETAILS ARE SHOWN IN THE PHOTO GALLERYPackage Includes:1 piece fully assembled Amplifier Board1 piece 200mm Long Double Ended Terminal Cable (You can cut off one end) Perfect for Crystal RadioWide Operating Voltage Range: 5-12VWith power indicator LEDPin connection leads for Input and PowerPackage Contents:= 1 Amplifier Board and 1 CableEasy to directly connect Audio Output from the Amplifier to your Earphone or a Speaker, to the Terminal Block10K variable potentiometer so, you can adjust the Amplification VolumePCB Board Size : 41 x 14mm(L*W)Very little distortion
