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.

First of all、 we need to know two concepts: billing weight unit、 first weight and additional weight

Billing weight unit: The international express industry generally takes 0.5KG (0.5kg) as a billing weight unit.

First weight and additional weight: the first 0.5KG is the first weight for international express delivery、 and every additional 0.5KG is an additional weight. Generally、 the cost of hoisting is higher than that of continuous hoisting.

There is one price between 0.5KG and 0.5KG、 which is the first weight price. The part exceeding 0.5KG will be charged according to the additional weight price

Therefore、 the actual freight is equal to the first weight price+additional weight price

When the actual weight of the goods to be delivered is greater than the volume weight、 the freight=first weight freight+(actual weight (kg) × 2－1) × Renewal freight

When the actual weight of the delivered goods is small but the volume is large、 the freight=the first freight+(volume weight (kg) × 2－1) × Renewal freight

Note that the freight here is only the basic freight、 not the final total cost、 and there may be other additional costs.

Packaging fee: Generally、 international express companies provide free packaging、 cartons、 bubbles and other packaging materials、 but many items、 such as clothing、 can be packaged without extra fine packaging、 but some express companies will charge a certain packaging fee for valuable and fragile items. Packaging costs are generally not included in the discount calculation.

Fuel surcharge: all major international express will be updated in real time according to market conditions. Please consult customer service for specific fees.

Other uncertain expenses: such as service fees in remote areas、 sensitive freight charges for sending batteries、 powders、 liquids、 food、 brands、 etc.、 which are mainly related to the items and regions you send.

Basically、 total cost=(freight+fuel surcharge) × Discount+packaging cost+other uncertain costs

In addition、 different countries and different logistics channels have different basic charging standards、 and the cost may also be affected by many factors such as flight outage. The specific charging standards can also be subject to the real-time quotation of the express company.

The international express line is a dedicated logistics transportation service independently developed by domestic express and logistics companies from domestic export to the target country、 or from the target country to domestic import. International express lines have the advantages of fast time、 low price and smooth customs clearance.

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.
