WS-01 220V 500W Passive Subwoofer Power Amplifier Special Hifi Power Amp For Home 5.1/2.1 System. Features: – High-power Hifi subwoofer amplifier with powerful driving force – Suitable for home 5.1 home theater system and 2.1 stereo system as bass compensation, making the bass part of the system more shocking and rich – Professional passive subwoofer amplifier: 300W at 8? ; 500W at 4? – Novel and concise appearance; cost-effective – Adjustable master volume and phase; professional frequency adjustment – Abundant ports, including SW subwoofer input port, left and right stereo output ports and XLR input port, easy matching to personal system – Frequency 20Hz-180KHz, allowing listeners to experience pure sound – Various audio signal input interfaces. Support left and right channel R+L music signal input. Can be connected to CDs, mobile phones, tablet computers, desktop computers and other common audio sources – Subwoofer pure bass signal input connects with pure bass output of home theater AV amplifier or preprocessor. Professional audio XLR port input supports mixer and effector – Constantly optimized classic circuits, quality internal materials and mature manufacturing processes. Circuit board with reasonable internal layout. The whole transformer (5KG) is made of high-temperature resistant and high-strength pure copper enameled wire, which makes the sound more real, natural, smooth and soothing – 6pcs 10000uf (for Rubycon/for Nichicon) electrolytic capacitors used as the main filter capacitors, ensuring stable power supply – 2SC5200x4/2SA1943x4 pair transistors; 6pcs 80V 10000uf filter capacitors – There are a large number of capacitor-resistor networks on the front panel of this unit. The tone part uses CBB capacitors (for Philips) for signal frequency division. All power supply decoupling adopts imported CBB capacitors. They not only carry out important frequency division filtering, but also carry out time phase advance compensation function, so that there is no delay between the bass and the main box. All these make the sound pure and vibrant – High precision resistors with 1% error are used. The German MKP-10, coupled for WIMA, was used in the audio path. The electrolysis is imported high-grade audio electrolytic capacitor (for Nichicon) as the filter and decoupling of the whole machine. Use non-inductive ceramic high-power copper pin resistance output channel to use Specifications: – Brand: ROYANGES – Rated power: 300W (8? 75KHz); 500W (4? 75KHz) – Output impedance: 4-16? – Signal-to-noise ratio:? 90dB (A weight, line input) – Frequency Response: 20Hz-180KHz (+10db, -20db) – Input Impedance: 100K – Output impedance: 4-16? – Input sensitivity:? 500MV – Distortion (THD):? 0.5% – Internal power tubes: 2SC5200x4, 2SA1943x4 – Power supply: 220V±10% 50Hz 330W – Machine size: 250 x 330 x 100mm/9.8 x 13 x 3.9 – Machine weight: 12.2KG/26.9 LB Package Included: – 1 x Amplifier – 1 x Power Cord – 1 x User Manual Attention: – Please adjust the phase and frequency according to the actual passive subwoofer to avoid the resonance frequency point of the passive subwoofer, otherwise there will be various noises, such as the mechanical noise of speaker cone. Usually it cost about 35USD-50USD. Thanks for your understanding. If you receive defective item, please kindly notify us within 14 days.
