For each minute of animation synchronized ...
A cable converter box or television converter box is an electronic tuning device that transposes/converts channels from a cable television service to an analog RF signal on a single channel, usually VHF channel 3 or 4, or to a different output for digital televisions such as HDMI.
The creator of Thorn EMI's three satellite channels as director of programmes was Julian Mounter, who joined Music Box from Thames Television.Recognising that income for satellite television would be slow in coming, Mounter set about negotiating revolutionary union deals to enable the use of smaller crews in the studio and on location, commandeered a boardroom at the headquarters of Thorn EMI ...
A passive electric power adapter, sometimes called a travel plug or travel adapter, allows using a plug from one region with a foreign socket. As other countries supply 120-volt, 60 Hz AC, using a travel adapter in a country with a different supply poses a safety hazard if the connected device does not support both input voltages.
A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. Also known as barrel connectors , concentric barrel connectors or tip connectors , these small cylindrical connectors come in an enormous variety of sizes.
A music box (American English) or musical box (British English) is an automatic musical instrument in a box that produces musical notes by using a set of pins placed on a revolving cylinder or disc to pluck the tuned teeth (or lamellae) of a steel comb.
An example of a design tradeoff in power connector selection is a coaxial power connector, which is usually set up so that power is fed from the female plug into the male jack (which is typically a part of the electronic device accepting the power). Although the plug is female, with a partially recessed center contact, it is still possible for ...
