Hi. A 'No sound' condition indicates a bad amp if you are certain that the woofer is wired properly. A schematic and a tester would be able to best assist with a DIY work - otherwise, you may need a technician.

Block Diagram

The following block diagram provides a high-level overview of the Jamo 360 subwoofer. It shows the major components and their relationships.

Block Diagram of Jamo 360 Subwoofer

Components:

  • Woofer: The woofer is the main driver that produces bass sound. It is a 10-inch long-throw driver with a powerful magnet and voice coil.
  • Crossover: The crossover divides the audio signal into two frequency bands: low frequencies for the woofer and high frequencies for the satellite speakers.
  • Amplifier: The amplifier powers the woofer. It is a Class D amplifier that can deliver up to 360W of peak power.
  • Inputs: The subwoofer has two inputs: one for line-level signals and one for speaker-level signals.
  • Outputs: The subwoofer has one output for the satellite speakers.

Connections:

  • The woofer is connected to the amplifier using a speaker cable.
  • The crossover is connected to the amplifier using a pair of RCA cables.
  • The inputs and outputs are connected to the amplifier using RCA cables.

Schematic Diagram

The following schematic diagram provides a more detailed view of the electrical connections and components of the Jamo 360 subwoofer.

Schematic Diagram of Jamo 360 Subwoofer

Components:

  • Woofer: The woofer is a 10-inch long-throw driver with a voice coil that is connected to a magnet. The voice coil is driven by an electric current from the amplifier.
  • Crossover: The crossover is a passive circuit that divides the audio signal into two frequency bands: low frequencies for the woofer and high frequencies for the satellite speakers.
  • Amplifier: The amplifier is a Class D amplifier that uses digital signal processing to convert the audio signal into an electric current. The current is then amplified and used to drive the woofer.
  • Inputs: The subwoofer has two inputs: one for line-level signals and one for speaker-level signals.
  • Outputs: The subwoofer has one output for the satellite speakers.

Connections:

  • The woofer is connected to the amplifier using a speaker cable.
  • The crossover is connected to the amplifier using a pair of RCA cables.
  • The inputs and outputs are connected to the amplifier using RCA cables.

Flowchart

The following flowchart represents the process of producing bass sound from the Jamo 360 subwoofer.

Process:

  1. The audio signal is input to the subwoofer.
  2. The crossover divides the audio signal into two frequency bands: low frequencies for the woofer and high frequencies for the satellite speakers.
  3. The amplifier amplifies the low-frequency signal.
  4. The amplified signal is used to drive the woofer.
  5. The woofer produces bass sound.
