USB-I/O Variable Sample Rate

ARX is excited to present the new ARX USB I/O VSR - a true Plug and Play USB 24 bit High Resolution digital/analog pro audio interface. VSR stands for Variable Sample Rate - which allows the unit to record and playback at three different sample rates: 44.1, 48, and 96 KHz

Plug and Play or Install ASIO Driver - your choice

The ARX USB I/O VSR installs as a fully compatible generic USB audio device. The default sample rate of 24 bit 44.1 KHz requires no special driver program installation on Mac OSX, Win XP, and Win7 or 8 - just plug and play.

ASIO Driver
To run the expanded Hi Res sample rates of 48 and 96 KHz, an ASIO driver is available for download from the ARX website - http://www.arx.com.au/drivers.htm.

Please make sure you have the USB I/O VSR connected to the computer before installing the driver.

Controls and Connectors
The front panel has Left and Right transformer balanced and isolated analog XLR Input and Output connectors that connect to all standard balanced analog Inputs and Outputs. On the rear panel there is a Type B USB connector, as well as a ground lift switch. Sample Rate LEDs indicate that the USB I/O VSR is connected and operating, and also which Sample Rate has been selected.

Transformer Balanced
The USB I/O VSR features full transformer balanced Inputs and Outputs, providing the isolation required to eliminate earth loops / ground hum and other extraneous interaction noise and distortion.

Analog style headroom
Analog 0dB In = –18dB, FS Digital, providing Analog style headroom when recording in the digital domain. The signal then reverts to 0dB Analog Out, giving you the best of both worlds.

Plug and Play Option
We recommend running Win XP or later, or Mac OS X. Plug the USB I/O VSR into an unused USB port on the computer and it will be recognised as ARX Systems USB, and ready to use.

About Variable Sample Rate
The USB I/O VSR has a default sample rate of 44.1KHz, the same as used for audio CDs. This is the sample rate you get when you Plug and Play with the USB I/O VSR.

But, by installing the ARX ASIO driver you can sample the music at 48KHz or 96KHz, for even greater definition.

Full Download and Installation instructions are on the ARX website.

The USB I/O VSR is housed in a heavy duty all-steel chassis finished in attractive matt textured polyurethane, with hardwearing epoxy screen printing and non-slip rubber base pad. It is ideal for interfacing any USB equipped computer (especially notebook/laptop computers) with the balanced inputs and outputs of professional sound systems.
Security features include Kensington®-type computer lock slot and optional bracket kit for under-table mounting.

The ARX USB I/O VSR is available in Dual Channel format, includes a premium quality USB-A to USB-B cable, and is hand made in Australia
