Introduction
This manual provides instructions for the C. B. Gitty 2.5-Watt Pre-Wired Amplifier Circuit Board. This board is designed for integration into custom audio projects, such as homemade amplifiers, offering a compact and pre-wired solution for audio amplification. It includes an integrated on/off/volume potentiometer and a 9-volt battery connector for ease of use.
Key Features
- 2.5-watt Artec amplifier board
- Integrated on/off/volume potentiometer
- Pre-wired with 12-inch leads for speaker, battery, LED, and input jack connections
- Designed for 9-volt battery operation
- Suitable for custom enclosures
Package Contents
The package includes the pre-wired 2.5-Watt Amplifier Circuit Board with an integrated on/off/volume potentiometer and a 9-volt battery connector. Please note that additional components such as speakers, input jacks, LEDs, and batteries are not included and must be sourced separately.
Setup and Installation
Careful attention to wiring is essential for proper function. Refer to the diagrams below for correct connection points. Positive wires are typically red, and ground/negative wires are typically black.

Text notes indicate red wires are positive and black wires are ground/negative.
Connection Steps
- Battery Connection: Connect the 9-volt battery connector to a standard 9-volt battery. Ensure correct polarity: the larger terminal on the connector connects to the smaller terminal on the battery (positive), and the smaller terminal on the connector connects to the larger terminal on the battery (negative).
- Speaker Connection: Connect the speaker leads from the amplifier board to your chosen speaker. The board has designated Speaker Positive and Speaker Negative terminals. Match these to your speaker's terminals.
- Input Jack Connection: Connect the input jack leads (IN and JK+) to your audio input jack. The IN terminal is for the signal input, and JK+ is typically for the ground connection of the input jack.
- LED Connection (Optional): If desired, connect an LED to the LED+ and LED- terminals. Ensure the LED is connected with the correct polarity (anode to LED+, cathode to LED-) and consider using an appropriate current-limiting resistor if not already integrated.
Important: Always double-check all connections for correct polarity and secure soldering (if applicable) before applying power to prevent damage to the circuit board or connected components.
Operation
Powering On/Off
The integrated potentiometer serves as both the on/off switch and volume control. Rotate the knob clockwise to turn the amplifier on and increase the volume. Rotate it counter-clockwise until it clicks to turn the amplifier off.
Volume Control
Adjust the output volume by rotating the potentiometer knob. Turn clockwise to increase volume and counter-clockwise to decrease volume.
Input Source
Connect your audio source (e.g., guitar, media player) to the input jack that is wired to the amplifier board. The amplifier will then process and amplify the audio signal.
Maintenance
The C. B. Gitty 2.5-Watt Pre-Wired Amplifier Circuit Board requires minimal maintenance. Keep the circuit board and its connections dry and free from dust and debris. Avoid exposing the unit to extreme temperatures or humidity.
To clean, gently wipe the circuit board with a soft, dry cloth. Do not use liquid cleaners or solvents, as these can damage the electronic components.
Troubleshooting
- No Power: Ensure the 9-volt battery is correctly connected and fully charged. Check all battery wiring for secure connections.
- No Sound Output: Verify that the amplifier is turned on and the volume is adjusted appropriately. Check all speaker connections for proper polarity and secure contact. Confirm that the audio input source is functioning and correctly connected to the input jack.
- Distorted Sound: If the sound is distorted, ensure the input signal level is not too high for the amplifier. Check that the speaker impedance is compatible with the amplifier's output.
- Intermittent Operation or Loose Connections: Inspect all soldered connections, especially if the unit has been handled roughly or subjected to vibrations. Re-solder any loose or cold solder joints if you have the necessary tools and expertise.
