The AJA 4K2HD 4K/UHD to 3G/HD/SD-SDI and HDMI Downconverter allows you to convert professional SDI 4K and Ultra HD signals to HD or SD resolutions. It outputs simultaneously to one 3G/HD/SD-SDI output and one HDMI output, allowing you to send the downcoverted signals to SDI and HDMI devices for on set monitoring or live broadcasting.

The 4K2HD features four SDI connections for four 1.5GHz, two dual-stream 3GHz, and four 3GHz 4K (4096x2160) and UHD (3840x2160) input signals. It supports multiple frame rates up to 50 and 60 fps at full 4K resolution. The output signal will have a matching frame rate for accurate viewing of your footage.

The software provides an easy-to-use graphical interface with detailed information about input and output formats as well as all configuration parameters.

        Special sales, demo items and promotions may have modified return policies. If an item from a bundle is returned for refund, the total bundle discount or the total value of the gifts will get deducted from the returned item prior to issuing a refund. If the bundle discount (or gift value) exceeds the value of the returned item, the difference must be paid to be able to return the item.

        Return autorization

        If you would like to return any item(s), please contact us by either emailing info@dittools.eu or calling (+372) 5556 0057. We will share with you a Return Merchandise Authorization (RMA) code and ask that you clearly mark this code outside of your shipping box as you ship your item(s) back for a refund.

        You will be liable for the shipping and any applicable customs/duty fees returning the item(s).

        Incorrect items

        If the return is made due to a faulty product, or an incorrectly shipped product, or if you are returning the item(s) due to a defect, or functionality issue, or because it is not the item you have ordered, we will gladly email or mail a return shipping label covering all shipping related expenses. In order to determine whether the return is initiated due to a technical problem, we may ask for you to provide visual support like images or a video on the item(s).


        Returned merchandise must be in its original packaging, and placed in a decent shipping box, e.g. the same box that we shipped the items to you in. Please make sure to clearly mark the RMA code you have received from us outside on the box.

        Do not forget to cover or peel off any existing shipping labels on the box.

        DIT Supplies OÜ cannot be held accountable for return shipments that have not reached us or returns made without RMA codes. We strongly advise that if you are returning the item(s) with a carrier of your choice that you use a traceable shipping method.

        It may take 4-5 business days for your return to reach us. Once it is received and inspected, your refund will be processed and automatically applied to your credit card or original method of payment within 14 business days. Please note that depending on your credit card company, it may take an additional 2-4 business days after your credit is applied for it to post to your account.

        Customs, duties & taxes

        There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
