Summary
D series digital amplifiers are suitable for home theater use.

Recently, many customers have asked Sinbosen which series of amplifiers they should choose if they want to buy an amplifier suitable for home theater. Sinbosen recommends the D series amplifier. As a professional digital amplifier device, the D series amplifier adopts advanced Class D amplification technology. It is loved by customers for its high efficiency, high sound quality, and compact size. With lower energy consumption and less heat generation, the D series amplifier performs well in a variety of scenarios such as professional stages, mobile performances, home theaters, and fixed installations.

Sinbosen's D Series amplifiers offer the option to equip Austrian brand Noctua fans, renowned for their exceptional cooling performance, low noise design, and high-quality materials. The D Series incorporates the NF-A4x20 FLX, a high-quality, low-noise fan that is particularly well-suited for quiet environments such as home cinemas.


Advantages and features of the NF-A4x20 FLX fan:
High-Efficiency Cooling and Silent Operation
High Static Pressure Design: The NF-A4x20 FLX is designed for high static pressure applications, providing robust cooling capabilities ideal for small enclosures, heat sinks, or power supplies where space is limited.
Low Noise Operation: Even at high speeds (5000 RPM), the fan generates minimal noise at just 14.9 dB(A). With the use of Low Noise Adapters (L.N.A.) and Ultra Low Noise Adapters (U.L.N.A.), the noise level can be further reduced to 12.2 dB(A) or 8.5 dB(A), respectively.
Flexible Speed Control Options
Multiple Speed Settings: The NF-A4x20 FLX offers three speed options:
Default Speed: 5000 RPM for high cooling demands.
Low Noise Adapter (L.N.A.): 4400 RPM for a balanced cooling and noise performance.
Ultra Low Noise Adapter (U.L.N.A.): 3700 RPM for ultra-silent operation.
PWM Temperature Control: The fan supports PWM temperature control, which automatically adjusts the speed based on system temperature, achieving a perfect balance between efficient cooling and low noise.
High-Quality and Durability
SSO2 Bearing Technology: Utilizing the second-generation Smooth Commutation Drive (SSD) technology, the fan operates smoothly even at low speeds, reducing resonance and noise.
Sterrox® Material: Made from high-quality Sterrox® liquid crystal polymer composite material, the fan blades are not only stronger and more rigid but also effectively suppress vibrations and resonance, further reducing noise.
Flexible Installation and Compatibility
OmniJoin™ Adapter Kit: Supports connection to proprietary fan interfaces, making installation convenient for users.
Extensive Accessories: Includes Low Noise Adapters, Ultra Low Noise Adapters, a 30cm extension cable, OmniJoin™ Adapter Kit, NA-AV3 anti-vibration mounting brackets, and fan screws, meeting various installation requirements.
Compact Design and Aesthetic Appeal
Compact Size: Measuring 40x40x20mm, the fan is ideal for small enclosures, power supplies, or other space-constrained devices.
Color Options: Available in black and white versions to match different aesthetic preferences.
Economic and Eco-Friendly
High-Efficiency Design: The fan's aerodynamic design reduces energy consumption and cooling demands, contributing to lower carbon emissions.
Low Energy Consumption: Even under high load, the NF-A4x20 FLX operates with low energy consumption, making it cost-effective and environmentally friendly over the long term.
