To put this into perspective, 24 bit/192 khz audio–the highest bandwidth in commercial use–uses approximately 10 MB/second per track of audio. USB 2.0 can handle bandwidth of 480 MB/second. USB Audio devices do not need the bandwidth of USB3.0 and USB3.0 is backward compatible with USB2.0. A USB audio interface attaches to the computer with a standard USB connector and to the device itself with any number of other connectors, ranging from proprietary connections to standardized connections. Most USB audio interfaces are USB 1.0 and USB 2.0 compatible, so you should have no problem getting a device to work with any computer manufactured in the last 5 years. But if a DAC is connected to the smartphone, then the phone is now the host and the DAC is the client. So, if a smartphone is connected to a computer, the computer is the host and the phone is a client. The source device that produces the data is called the USB Host and the receiving end is the USB Client. USB Audio is a standard for digital audio used in PCs, smart phones and tablets to interface with audio peripherals. Don’t confuse the USB standard with the port type. For example, the 2015 MacBook and the second-gen Chromebook support the USB 3.1 standard on their Type-C ports, while the OnePlus 2 uses the USB 2.0 standard despite a Type-C port.

This reversible plug is distinct from USB 3.1, though manufacturers may choose to support both at once. USB 3.0/3.1 is also compatible with USB Type-C, the latest plug design that’s just starting to gain adoption. But if WR-100 is connected to NuPrime IDA-8 or DAC-9, a single cable is all that is needed. For example, if NuPrime WR-100 is to be connected with a non NuPrime DAC, it would have to be powered by a 5V power adapter and connect its optical S/PDIF output to the DAC. It is not a USB standard! NuPrime wireless devices (Bluetooth dongle, WiFi audio receiver) use this custom digital port for 5V power as well as digital music signals (in S/PDIF format). The other port is a proprietary NuPrime digital port that uses the same USB Type-A connector. One of the ports is a standard USB 2.0 port (for audio, USB 2.0 is the standard and USB 3.0 is backward compatible with USB 2.0) for USB audio use. Some of the NuPrime models come with two Type-A ports. NuPrime’s DACs (including Digital Integrated Amp) are all USB client devices and they are designed to play music from computer, smartphone or tablet. Client devices can not work with each other, unless one of the device has the capability to become a host. Printer and USB hard drive are USB client devices. When a smartphone is connected to the computer, it functions as a client device to the computer. Some devices such as smartphone or tablet can act as USB host or client device. The USB communication is always between a host and a client devices. The USB standard and port type set the physical properties of how devices are to be connected to the computer and the speed limit.

USB Audio is a software standard that defines how audio devices can communicate with the computer to play music. NuPrime communicates and decode digital music from the computer through USB Audio (this is a software standard, not physical USB standard). In short, NuPrime customers benefit from our R&D, efficiency, and fruitful associations.įor a complete history and explanation of USB standard (1.0, 2.0, 3.0, 3.1) and port types (A, B, C, micro, etc), refer to Wikipedia USB article. On occasion, we partner to develop a product another company does better. Any components we require are conceived and achieved in-house. Our stocked parts range from raw materials and ICs to semi-assembled boards. Our in-house engineering team makes it unnecessary to spend elsewhere for what we do so well. Atypically, NuPrime is vertically integrated: we don’t subcontract for amplifiers and power supplies. It isn’t often that a brand owns its factory. Typically a high-end brand works with an OEM factory, including supplier factories, to achieve its target products. Similarly, our amplifiers employ a naturally occurring self-oscillating design principle to generate the PWM pulses for Class D sampling rather than incorporating a relatively expensive PWM generator. The designs for expensive preamps are now found in mid-priced amps and DACs, costing an order of magnitude less. Innovation and performance advances have reduced the cost of manufacturing. We are an engineering company, and we price our products based on the materials, labor, and other expenses that go into them. We don’t price our products based on how good they sound, how much weight they have, or how they compare to the competition.
