SET MAC AUDIO INPUT TO USB DRIVER

Please see the Audio Device Driver Programming Guide for more details.ДЄppleUSBAudio is a mature driver that supports many USB Audio 1.0 and 2.0 features. AppleUSBAudio builds upon the IOAudioFamily layer which provides general audio driver functions like maintaining the sample and mix buffers, facilitating communication over the kernel and user space boundary through user clients, and more. The AppleUSBAudio driver communicates to devices via the USB transport, using the IOUSBFamily APIs.

In addition to transporting audio data between the hardware and the hostвЂ™s sample buffer, it also communicates format and control changes between the host and the device (like volume, mute, format, input/clock source, etc.) AppleUSBAudio presents these hardware resources to applications through the HAL (audio hardware abstraction layer.) Figure 1 AppleUSBAudio in the Mac OS X audio stack Figure 1 shows where AppleUSBAudio fits in the Mac OS X audio stack architecture. Works with all USB 3.AppleUSBAudio is an I/O Kit based kernel driver that is designed to support both USB Audio 1.0 and USB Audio 2.0 class compliant devices.Robust metal housing ensuresВ roadworthiness.Asynchronous transfer system unaffected by computerВ jitter.4x upsampling during A/D and D/A conversion for reduced noise and enhancedВ fidelity.High-performance mic preamps with up to +60dB ofВ amplification.

SET MAC AUDIO INPUT TO USB PRO

Compatible with all popular DAW and streaming software, including Cubase, Logic, Garage Band, Pro Tools, Ableton Live, andВ others.

Direct Monitoring switch for zero latency monitoring in mono orВ stereo.

Independent gain controls and clip LEDs for eachВ input.

Вј' headphone jack with dedicated levelВ control.

Two balanced TRS output jacks for connection to amplifiers or self-poweredВ speakers.

Hi-Z switches allow direct connection of electric guitar orВ bass.

Two combo balanced XLR/TRS input connectors accept both mic- and line-levelВ signal.

Low latency overdubbing and direct monitoring for zero-latency monitoring in mono orВ stereo.

Loopback function for webcasting, podcasting, gaming, and other live streamingВ applications.

Support for recording and playback up to 24-bit/192В kHz.

2-in/2-out SuperSpeed USB 3.0 audioВ interface.

For A/D conversion, this means less aliasing noise for D/A conversion, this means increased clarityВ andВ fidelity. In other words, when the sampling frequency is set to 44.1 kHz or 48 kHz, the UAC-2 processes the signal at high resolution 176.4 kHz or 192 kHz. In addition, the UAC-2 performs 4-times upsampling during both analog-to-digital (A/D) and digital-to-analog (D/A) conversion. The UAC-2 uses high-end components such as the Burr Brown PCM4202 analog-to-digital converter and AKM AK4396 digital-to-analog converter.

* Optional power adapter and Apple Camera Connection kit or Lightning to USB Camera AdapterВ required Last but not least, a Class Compliant Mode switch enables the UAC-2 to be connected to anВ iPad.* MIDI In and Out connectors allow interfacing with devices such as electronic keyboards and drum machines. A phantom power switch applies +48 volts to the mic inputs, allowing you to use the UAC-2 with studio-quality condenser microphones, and a three-way Direct Monitoring switch enables monitoring of input signal with zero latency in both mono and stereo. Dual-balanced TRS output jacks enable you to connect the UAC-2 to amplifiers or self-powered speakers, and there's an independent Вј' stereo headphone jack with dedicated volume control for private monitoring of the input or outputВ signal.Дedicated input gain controls and Clip LEDs make it easy to set optimum input levels, and a large Output knob enables fast control over overall output level. Dual front panel combo XLR/TRS inputs allow you to connect a wide variety of microphones as well as line-level signals from electronic keyboards and music players-even passive instruments such as electric guitars and basses. The USB 3.0 connector on the rear panel carries digital signal to and from your computer in addition to providing power to the UAC-2-no batteries or external power required.
