SLV BL7 Version 1 Channel Module – Professional Power Drive PCB

The SLV BL7 Version 1 Channel Module is a high-performance audio engine designed for the demanding requirements of professional sound reinforcement. Operating on a Class H architecture, this module dynamically adjusts its voltage supply to maintain high efficiency and reduce thermal waste during peak performance. This listing is for the fully populated PCB assembly without the aluminum heatsink, making it an ideal choice for technicians performing direct board swaps or custom thermal integrations.

Key Features & Build Quality

• High-Output Performance: Engineered to support the BL7’s robust power profile, providing clean and impactful audio for full-range cabinets.

• Professional Semiconductor Array: Features high-current Toshiba bipolar transistors for superior reliability and low-distortion signal reproduction.

• Class H Efficiency: Utilizes multi-rail voltage switching to ensure the system runs significantly cooler than standard Class AB designs.

• Integrated Protection Circuitry: Features onboard sensors that communicate with the amplifier’s central protection system to guard against Short Circuits, DC Offset, and Overheating.

• Precision Signal Integrity: Populated with high-tolerance metal film resistors and professional-grade capacitors to ensure a high Signal-to-Noise ratio of over 97dB.

• Flexible Connectivity: Includes standardized multi-pin signal headers and high-current wiring looms for secure and reliable internal connections.

Technical Specifications (BL7 V1 Profile)

• Compatible Model: SLV Black Series BL7 Version 1.

• Amplifier Class: Class H.

• S/N Ratio: $>97\text{dB}$.

• Damping Factor: 1000 (Provides exceptional control over speaker cone movement).

• Slew Rate: 42V/us.

• Cooling Requirement: Must be mounted to an appropriate forced-air tunnel heatsink.

Applications

• Factory Spec Repair: The direct replacement module for repairing damaged or failed power stages in the SLV BL7 V1 chassis.

• Touring & Rental Maintenance: A vital spare component for sound technicians to ensure minimum downtime for professional audio inventory.

• Custom Audio Projects: Provides a pre-engineered, high-power drive solution for custom professional audio builds.

Technical Note: This module handles High-Voltage DC. Installation must only be performed by a qualified technician. Ensure that the amplifier's capacitor bank is fully discharged and that high-quality thermal paste is applied between the transistors and your heatsink before powering up the unit.
