Secondhand U-PRO2 280W+100W Digital Class D Power Amplifier Board Ultra-low Distortion PWM Modulator for PASCAL

Function:
Specially Designed for 100/70V Line Amplifiers:
- The U-PRO2 series has been optimized for specific requirements of 100/70V line applications. This is evident in high-voltage tracks that provide direct drive. Many tenders require compliance with Energy Star standards. A wide range of protection measures can prevent malfunctions during system installation.

Suitable for 1RU½ Rack Size:
- The width and height of the U-PRO2S module are only 38x70mm (1.5x2.8 inches), making it the only solution on the market with integrated power and direct drive capabilities, and can be installed in a 1RU4 size rack. This eliminates the bulky external power supply in other similarly sized 100/70V line amplifiers.

Audiophile Level Performance:
- The proprietary UMAC Class-D technology for Pascal provides unparalleled high performance specifications, including the highest dynamic range and lowest distortion performance among any similar professional audio amplifier. This makes the U-PRO2 series suitable for professional audio applications as well as high-end HiFi and AV products.

General Power Supply and PFC:
- For Pascal UREC PFC (Power Factor Correction) power technology enables universal AC power operation without the need for local market specific power regulation products or reliability concerns. This power supply can provide stable and steady electricity worldwide.

Unparalleled Efficiency:
- Like the S/T and L-PRO series, the U-PRO2 series boasts the world's best system efficiency, minimizing the need for radiators and cooling. Low temperature operation also helps improve the long-term reliability of amplifiers.

Auxiliary Power Supply and Reading Device:
- The auxiliary power supply can be used for DSP or analog I/O cards. DSP/network or I/O board can read protection/mute, temperature, and clipping signals. The U-PRO2 series has ultra-low standby power consumption, complies with EuP2013 and Green Energy Star standards, and has automatic standby/wake-up function with selectable time settings.

Interface Compatible with T-PRO, S-PRO, and L-PRO:
- The U-PRO2 series has compatible pin interfaces and the same output voltage as popular S-PRO, T-PRO, and L-PRO modules with higher current capability; Therefore, the front-end electronic devices of S-PRO, T-PRO, L-PRO, and U-PRO2 series are all compatible with plug and play.

Obtained Security Certification - Compliant with EMC Standards:
- For Pascal amplifier module has passed safety certification and verified compliance with EMC requirements. CB reports and UL certificates can be provided to facilitate market approval.
