Connection interfaces that the audio interface is equipped with.
-
USB A. Connection via standard USB port. Until recently, this was the most popular interface for external peripherals, found in almost all PCs and laptops. Nowadays, it is often replaced by a USB type C port (see the corresponding paragraph). Most USB A audio interfaces draw power directly from the PC or other host device.
-
USB type B. The connector has a characteristic square shape, noticeably different from the well-known rectangular USB A ports. In audio interfaces, it is used to transmit signals from external sources to a computer for recording and processing.
-
USB type C. A peripheral connector with a symmetrical contact group, which often replaces full-size USB ports on board modern PCs and laptops. Many new models of audio interfaces are being made for this interface. An exception to the rule is individual instances for Thunderbolt. For them, it is Thunderbolt that is indicated, and not USB type C.
-
Thunderbolt v2. Initially, Thunderbolt is a universal connector used primarily in Apple computer equipment. On board audio interfaces it is used as a general peripheral connector (similar to USB). This uses the miniDisplayPort hardware port. The data transfer speed in this version reaches 20 Gbit/s. Recently, the v2 edition has been rep
...laced by the Thunderbolt v3 version (see the corresponding paragraph).
- Thunderbolt v3. A universal interface that is found mainly in Apple technology. In audio interfaces it is used as a general peripheral connector (similar to USB). Specifically, Thunderbolt v3 provides data transfer speeds of up to 40 Gbps and uses a USB type C hardware connector (as opposed to earlier versions based on miniDisplayPort).
- Lightning. A connector used exclusively in Apple portable electronics (since 2012). Accordingly, audio interfaces with such a port are aimed at ease of connection to iPhones and iPads. Note that today there has been a transition from proprietary Lightning to the common USB type C - the latest generations of Apple gadgets are produced with just such a peripheral connection connector.
- mini-USB. A smaller version of the full-size USB interface, created for portable equipment. It is found very rarely in audio interfaces.
- FireWire. Universal connector, also known as IEEE 1394 or i-Link. In terms of functionality, it is analogous to USB, and in some characteristics it even surpasses it. However, FireWare is much less common. Used to connect to computers and some types of specialized audio equipment.
— Dante Dante connectors are used to connect audio interfaces to a network to transmit audio digitally. In this case, a standard Ethernet port (RJ-45) is used for physical access to the network.Power supply methods provided in the device. There are models that combine combined power supply methods - for example, from the mains and USB. For more details, see individual help items.
—
From the network. Powered by a regular household power supply of 230 V. Stationary audio equipment uses only this method of power supply, but in compact devices it can be combined with a USB connection, battery power, or the presence of a battery.
-
USB. Powered by the same USB connector that connects the device to external equipment. This power supply method allows you to do without unnecessary wires and work independently of sockets, but its power is low, so this option is used only in compact devices. Some models combine USB power with a built-in battery or supplement mains power, providing a backup option in case there are no outlets.
—
Battery. The presence of a built-in battery allows the device to operate independently of any external energy sources, however, the period of such operation is limited - at some point you will still have to take a break to charge the battery. In its pure form, this type of power supply is extremely rare - much more often the rechargeable battery is provided as a “backup option” that supplements power from the network or USB (see the corresponding paragraphs).
—
Batteries. Powered by
...replaceable elements of a standard size - for example, “finger-type” AA. Note that among such elements there are both disposable batteries and rechargeable batteries. This gives the user a choice: regularly purchase fresh elements or spend money once on batteries and a “charger” for them. However, in any case, power from batteries is associated with additional costs - such power supplies are usually not included in the kit and have to be purchased separately. This option is found mainly among portable models.
