- Identify the output of each amplifier and the common load, such as a speaker. The output of each amplifier is usually labeled as “output” or “speaker out.”
- Connect the output of each amplifier to the common load using a cable. Make sure the cable is compatible with the connectors on both amplifiers.
- Set the gain of each amplifier to the desired level. The gain control determines the amount of signal that is sent to the load.
- Test the connection by playing music through the system. Adjust the gain controls as needed to achieve the desired sound.
Key Considerations for Parallel Connection
When making a parallel connection, there are several key considerations to keep in mind:
- Impedance matching: Make sure the impedance of the output of each amplifier matches the impedance of the common load. Impedance mismatch can result in signal loss and distortion.
- Gain staging: Make sure the gain of each amplifier is set correctly to avoid distortion and signal overload.
- Phase alignment: Make sure the phase of each amplifier is aligned to avoid phase cancellation and distortion.
Common Pitfalls to Avoid When Connecting Amplifiers
When connecting amplifiers, there are several common pitfalls to avoid:
- Incorrect impedance matching: Impedance mismatch can result in signal loss and distortion.
