SK Series Smart Amplifiers（SK-240 SK-280 SK-2100）

This series includes 3 models：SK-240，SK-280，SK-2100.

Smart Integrated Multifunctionality: Combines intelligent power sequencing with high-fidelity, low-power consumption amplification. Features Class H circuitry and SMT manufacturing, housed in a 2U chassis. Delivers rich bass, beautiful tonal quality, and low distortion.

Convenient Smart Control: Panel-mounted Ethernet port supports external 86-type switch box integration. Seven power sequencing channels with freely configurable delay settings. Equipped with LCD display and RS-232 control port for remote centralized management and panel lockout to prevent accidental operation.

Stable, Durable, Long-Term Operation: Powered by an oversized toroidal transformer and 10000μF capacitors, with optimized heat dissipation structure and temperature-controlled fans. Automatically adjusts power supply during load/temperature anomalies to ensure sustained high-power operation.

This series includes 3 models：SK-240，SK-280，SK-2100.

Key Features:

1. Professional all-in-one multifunctional audio power amplifier integrating intelligent power sequencing system and high-fidelity low-power consumption amplifier system;

2. Panel features a dedicated Ethernet port for connecting to an 86-type switch box externally, eliminating frequent cabinet power cycling. Panel includes circuit breaker;

3. 7-channel sequenced power output with freely configurable delay times for each channel’s power-on/off (0~999S per channel);

4. LCD screen dynamically displays voltage, date, time, and channel status;

5. Customizable overvoltage and undervoltage protection ensures stable power output;

6. Equipped with a 232 central control port supporting external central control devices;

7. Remote centralized control with built-in device ID detection and configuration for each unit;

8. Panel LOCK function prevents accidental operation. Light touch powers on, long press for 3 seconds powers off (Note: Do not long press during startup, otherwise the unit will automatically lock. Power must be disconnected to unlock, then light touch to restart);

9. The entire unit employs SMT manufacturing processes. The amplifier utilizes Class H circuit technology, delivering high-efficiency power conversion and refined circuit layout. Features an oversized imported iron-core toroidal transformer design and 10000UF high-capacity capacitors for rich, deep bass;

10. Optimized heat sink structure and high-quality cooling fans ensure reliable operation during prolonged high-power use. Fans automatically accelerate based on internal temperature changes. When connected load impedance is too low or temperature becomes excessively high, the unit adjusts power supply output to reduce internal resistance. This improves sound quality while effectively protecting the equipment, significantly enhancing reliability;

11. High amplifier switching speed delivers beautiful tonal quality with low distortion. The entire series features a 2U chassis design.
