2 channels 400w digital active speaker amplifier module or bridged 1000w power amplifier module board amplifier module dsp
Product Description
PA402D active power amplifier module is a new multi-channel, multi-function, multi-purpose new product developed by our company. It is the combination of the world's most advanced DSP, switching power supply and digital power amplifier (CLASS-D). It is also the combination of the top-notch strength of audio technology and the precision of manufacturing. The module uses advanced PWM modulation technology switching power supply together with the latest second-generation CLASS-D digital audio technology and professional electro-acoustic technology to optimize DSP crossover network system combination. 95% of its circuit boards are equipped with SMT technology to secure the product’s consistency and stability. The active module pursues a faster response speed, a higher damping factor, and a more complete protection system. Due to the combination of PWM and PFM modulation mode, the output signal of the power amplifier can accurately and quickly track the input signal. It can adaptively eliminate the noise and distortion introduced by the drive, amplification and filtering of the power amplifier. With its outstanding sound quality, the module has broken through the high evaluation of digital power amplifiers in the whole industry and can be used by any customer in any environment confidently. By reducing your time-to-market and saving your R&D costs, energy and resources, we provide you with all the resources to bring your products to the market in the most convenient and fastest way

Q1: What’s your terms of payment?
A1: Payment, 30% in advance, balance before shipment.
If you have another question, pls feel free to contact us as below:
Q2: What's your delivery term?
A2: We quote and deliver on the term of FOB Huangpu or Shenzhen (except EXW term for small orders). Of course, CIF, C&F or even door to door is acceptable, so we will check and quote shipping cost additionally.
Q3: How long is the lead time?
A3: Generally 2 weeks. If any urgent orders for projects, we will do our best to expedite the process and deliver faster. But for OEM orders, lead time would be little longer on the first order since we need more time to communicate the requirements and confirm artworks...
Q4: How do you pack my goods to ensure intactness in the course of transportation?
A4: We always take care of our products and pack them properly! For example, we use strong carton box (export carton) stuffing with enough foam bubble and inner boxes for air shipment or express, and optional pallet packing could be used for LCL sea shipment for better protection.
Q5: How about the warranty and after-sales service?
A5: Our warranty is two years, but considering the long transit time to overseas customers, we offer three years warranty. For any problems (non-human induced), we shall provide you free spare parts and instruction for repair.
