Know before you buy
The amplifier utilizes a convection-cooled design, which relies on large, efficient heatsinks to dissipate heat naturally. This eliminates the mechanical noise and potential failure points associated with internal cooling fans, ensuring a silent operation.
Yes, the 9B³ includes a network interface that allows you to monitor the unit's status, temperature, and clipping warnings through a simple web browser interface. This is particularly useful for installations where the amplifier is tucked away in a rack or cabinet.
No, the 9B³ features a SoftStart power-up sequence. This technology manages the inrush current during startup to prevent the amplifier from drawing too much power at once, which protects your home's circuit breakers.
By giving each channel its own dedicated power supply, the amplifier prevents crosstalk between channels. This ensures that a high-demand signal in one channel does not affect the performance or clarity of the others, resulting in a more dynamic and precise soundstage.
Yes, the 9B³ features switchable gain settings. This provides flexibility to match the amplifier's sensitivity with your specific preamplifier or processor, ensuring an optimal gain structure for your entire audio system.
No, the 9B³ is a dedicated power amplifier and does not include an internal digital-to-analog converter or a remote control. It is designed to focus entirely on high-fidelity power amplification for your existing home theater processor.
