PA-49 Silvery HiFi Power Amplifier 180Wx2 STK496-430 Audio Integration Module Bluetooth5.3 Lossless Audio Amplifier 220V
Description:
- PA-49 is designed to meet the high requirements of HIFI listening. The front stage produces sound and the rear stage outputs power. The product's front stage is based on the famous C3850 circuit for Accuphase, with a large open-loop gain, diamond shaped diamond architecture, and Class A front-end output, which makes the details and air feel very excellent. The rear stage is a classic thick-film circuit, with strong low-frequency elasticity and extremely delicate high-frequency, combining powerful audio.
- This machine uses original thick-film STK496-430 audio integration module for Sanyo, which has extremely high precision, high output power, minimal distortion rate, stable performance, and excellent heat resistance. Its sound quality is mellow and can provide rich and full-bodied sound effects, which are more authentic than the sound emitted by common integrated circuits and transistor circuits.
- The core power adopts for Sanyo STK496-430 module, with a power of up to 150W, 6ohms per channel (real power), and a distortion rate THD of only 0.4%. The actual listening experience is low, warm, and durable.
- All aluminum alloy panel shell, laser engraved fonts, rust free, deformation free, and word-missing free, with an appearance only available on high-end machines.
- With 3 audio input options, there is no need to manually plug and unplug multiple input signals here, which is very convenient.
- A pure copper wound A-core non-breakpoint transformer with powerful power reserve, like the engine of a car.
- DC protection system: automatically detects the condition of the internal wiring of the machine, automatically disconnects the circuit from the speaker, and ensures that the speaker is always working in a safe state.
- Simulated impact delay system: prevents the speaker from being impacted at the moment of startup, and eliminates the popping sound generated by startup.
- Temperature overheat protection system: when the temperature exceeds the safe range, it can automatically reduce the current and output, protecting the overall safety of the machine.
Bluetooth5.3:
- Compared to Bluetooth5.1 version, Bluetooth 5.3 can bring twice the data transmission speed and an 800% increase in data transmission capacity.
- Using Bluetooth 5.3 can transmit and receive more data at a faster speed.
- Different working distances: compared to Bluetooth 5.1 version, Bluetooth 5.3 has increased its bandwidth (transmission speed) from 1Mbps to 2Mbps, increasing the transmission distance by four times, which is the theoretical effective working distance of 300 meters. Low power mode is also available.
