For international shipping please contact our sales team via email - sales@chinam.com.hk

Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.
  • We may deliver the merchandise in one or more installments, and some of the merchandises may be delivered directly from suppliers. Any times and dates given for dispatch of merchandise, or the length of time that merchandise will take to be delivered, are only estimates. If we are unable to meet any stated dispatch or delivery dates or times we will inform you as to the progress of your order. You agree and accept that under no circumstances will we accept cancellation of order or refund.

Signature On Delivery

  • Most of our shipments contain valuable items. If you will not be in attendance to accept delivery of your purchase, consider shipping to someone you trust will be able to sign for your package. For your convenience, you may prefer to have your order delivered to your office address. If you choose this option, please include the name of your business in the address. Please note, if you choose this option, goods may be left with reception or the Mail Room.
  • As our carriers require a signature on delivery, the carrier will leave a calling card if you are not at home. Please contact the carrier to reschedule delivery.
  • For postal deliveries, no signature is required and order status tracking is not available.
  • Delivery failure due to no one answering the door upon the arrival of goods at the appointed time, or to circumstantial limitations such as the entrance being too small, will require a rescheduled delivery and therefore incur double delivery charges.
  • We will deliver the merchandise ordered by you to the address you give us for delivery at the time you make your order through our staff or a third party provider. You agree to present your photo identification upon request when you acknowledge receipt of the merchandise. The merchandise shall be, and shall be deemed to be, delivered and accepted by you when the merchandise are delivered to the address you give us for delivery. You agree and accept that we are entitled, at our option, to charge you additional costs or cancel your order in the event of your failure to accept delivery for whatever reasons.


  • You will become the owner of the merchandise you have ordered when they have been delivered to you. Once merchandise has been delivered to you they will be held at your own risk and we will not be liable for the loss or damage.
  • You may not export any products purchased at CHINAM online store. We sells and ships products to end-user customers only. Notwithstanding order confirmation, CHINAM may cancel any order where it has reasonable grounds to believe the product is not being purchased for end use.
  • If there is any inconsistency or ambiguity between the English version and the Chinese version, the English version shall prevail.
  • We reserve the final right to terminate or alter the above terms and conditions. In the event of any dispute, our decision shall be final and conclusive.

Thunderbolt Gigabit Ethernet Adapter for Macs with Thunderbolt Ports

The Avid® Pro Tools | Carbon audio interface for music production has been described as a creative game changer; its innovative use of eight onboard HDX processors and a custom FPGA enable you to track and monitor with near-zero latency when using AAX DSP plug-ins. Because Carbon connects to your Mac® over Ethernet using a proprietary version of AVB (Audio Video Bridging, aka IEEE 802.1), you’ll have to use an AVB capable Thunderbolt™ Gigabit Ethernet adapter if your computer doesn’t have onboard Ethernet. The Avid Qualified Sonnet Thunderbolt AVB adapter is your single-adapter solution for connecting your Mac with Thunderbolt 4 or Thunderbolt 3 ports to the Carbon interface.

Avid-Compliant Ethernet Adapter – Connect to Other Devices On a Network

Beyond its support for the Pro Tools | Carbon interface, the Sonnet Thunderbolt AVB Adapter enables you to add your Mac as an endpoint in an AVB network and connect to other devices such as audio interfaces, mixers, plug-in processors, personal monitor stations, stage boxes, speakers, speaker processors, and others. Audio Video Bridging support makes the adapter perfect for use in pro audio and video applications where synchronization of data streams is critical.

What is the Benefit of an AVB Network?

An AVB network is extremely reliable since it is designed to reserve a portion of the available Ethernet network bandwidth for its own data. Packets of AVB data are sent regularly in allocated slots within the reserved bandwidth, ensuring AVB packets maintain time synchronization.

Thunderbolt Interface for Low Latency

Featuring a 40Gbps Thunderbolt™ interface, the Sonnet Thunderbolt AVB Adapter supports the low-latency, fully synchronized streaming of audio and video over Ethernet required for Avid Pro Tools | Carbon and AVB support.

Bus-powered Operation

Operating off its Thunderbolt connection, Sonnet’s Thunderbolt AVB Adapter is bus-powered, so there’s no need to plug in a power supply or power cable.

Pocketable. Powerful. Gigabit Ethernet to Go

The Sonnet Thunderbolt AVB Adapter measures just 1.5 inches wide by 3.9 inches deep by 0.8 inches tall, small enough to tuck out of sight or fit easily into a pocket in your backpack or equipment bag. Enabling truly portable use, the Sonnet adapter is powered by your computer’s Thunderbolt port, connected through the included Thunderbolt cable.

Simple SetupDrivers and Configuration App Built Into macOS

The basic drivers that support the Sonnet Thunderbolt Adapter are included in macOS®. Basic configuration takes place in Network control panel, while configuration for use in AVB applications is handled in the Audio MIDI Setup application and control software.

The Right Connection40Gbps Thunderbolt Cable and ThunderLok 3 Included

Sonnet includes a 40Gbps Thunderbolt cable that is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip that prevents accidental cable disconnections — just slide it over one end of the cable, and then plug in the connector and secure it to the adapter by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable, so it won’t get lost when not in use.
