🛠️ Technical Information:

The Logic 7 system is a fiber-optic (MOST Bus) based audio distribution system that relies on seamless communication between the head unit, amplifier, and speaker network. The amplifier contains numerous channels (up to 16) with separate digital signal processing (DSP) and integrated preamp stages. Common failure points include:

• Overheated MOSFETs or output transistors

• Corrupt or damaged signal processors

• Faulty internal relays or caps causing intermittent audio

• Burned out power supply rails causing complete amplifier shutdown

Our team uses high-grade replacement components and reflows key solder joints to ensure reliable long-term performance.
