Amplifier generally refers to the power amplifier, a most basic equipment in the audio system, commonly known as "amplifier", its task is to amplify the weak electrical signal from the signal source (in the professional audio system, it is from the mixer) to drive the speaker to emit sound. It can also refer to other devices for power amplification. The function of the power amplifier is to amplify the weak signal from the sound source or preamplifier and push the speaker to play sound. A good sound system amplifier plays a role. Professional power amplifier physical diagram power amplifier, is the largest family of all kinds of audio equipment, its role is mainly to amplify the weak signal input by the audio source equipment, generate a large enough current to push the speaker for sound playback. Due to the consideration of power, impedance, distortion, dynamics, and different usage ranges and control adjustment functions, the signal processing, line design, and production process inside different amplifiers are also different.

For medium and large products、 the cost of logistics and express delivery is a big part、 and the seller's top priority is to give consideration to freight and timeliness、 which directly determines whether he can have greater competitiveness in the competition with peers. The following factors need to be considered when selecting the overseas warehouse storage and final process one piece delivery mode: overseas warehouse location、 final process channel and storage system、 response speed、 ability to deal with emergencies、 peripheral supporting services、 etc.

The location of overseas warehouse mainly depends on whether it is distributed in the region of its main purchasing group、 whether it is close to the port、 whether it covers the United States、 etc. Among them、 whether it is close to the port will affect the timeliness and cost of trailer warehousing、 and the other two will directly affect the high and low cost of the final journey and the length of the timeliness、 which cannot be ignored.

However、 the tail channel is equally important. Besides the high and low cost、 we should also consider the stability of the tail channel and the ability to deal with emergencies such as stock explosion. It is better to choose your own tail channel. If it is the tail channel of others、 the price (changed) is not superior. Besides、 the response speed to deal with various problems is also unmatched. The experience is greatly discounted、 and even the problem cannot be solved at all. In addition、 such as the storage system、 surrounding facilities、 and whether the warehouse specializes in medium and large items are also factors that sellers need to consider when selecting cooperative overseas warehouses.

There are two main forms of air cargo: one is through air freight agency、 and the other is directly handled by the carrier to the airline. As the bridge and link between the carrier and the carrier、 air transport can not only act as the agent of the carrier、 but also handle the carrier's cabin、 consignment、 preparation for consignment、 customs declaration、 handover、 etc. on behalf of the carrier; It can also be used as the agent of the airline to receive goods、 book space、 make master waybill、 and issue the shipping documents of the agency.

First、 most air freight forwarders are very familiar with transport links and relevant rules and regulations、 have extensive contact with civil aviation、 customs、 commodity inspection and transportation departments、 and have the relevant conditions for handling transport procedures. At the same time、 air freight forwarders have branches or agents around the world、 which can timely contact and control the whole process of cargo transportation. Airplanes are only responsible for transportation from one airport to another. Therefore、 it is more convenient to entrust an air freight agent to handle import and export cargo transportation than to directly handle it with an airline.

Secondly、 an important business of the air freight forwarder is to act as an agent for centralized consignment. It is about to merge some goods that are transported separately into a batch、 send the goods to the same destination airport with the same master waybill、 receive the goods by the local agent、 and distribute them to the actual consignee after customs declaration. This centralized shipping method can reduce the freight of airlines、 and both agents and cargo owners can benefit from this service (Consol container、 bubble separation、 etc.).

Thirdly、 for airlines、 they can also make profits through agency business. Although the airline company has to pay some remuneration (freight discount) to the agent、 the agent company has organized a number of sources of goods、 contracted a large number of customers、 centrally checked tens of millions of goods、 saved a lot of manpower、 material resources and time、 and further developed the air transport market. At the same time、 both the carrier and the carrier can get convenient and fast value-added services in the whole process from the freight forwarder、 which can not only save costs、 but also improve efficiency and enhance the competitiveness of the industry.

The charging standard of international express depends on the actual weight and volume weight. Calculation method of package volume and weight: (length x width x height) (cm) ÷ 5000. Note that the unit of length、 width and height is cm. If the cargo of international express package is less than 0.5 kg、 it will be charged as 0.5 kg. Goods below 21Kg (46.3Ib) are charged as small goods、 the first weight and the second weight. The charging unit is 0.5Kg (1.1Ib)、 and goods above 21Kg are charged as large goods.
