MAudio Audiosport Quattro 4x4 USB Audio/MIDI Interface Specifications
M-Audio's Quattro USB audio interface is perfect for any application that requires high-quality audio as well as portability and/or compactness, such as tight studio spaces. The Quattro provides four .25-inch TRS analog audio inputs and four analog audio outputs in the ASIO (Audio Stream Input/Output) format and two in/out in Windows MME (multimedia extensions) or when using the Macintosh Sound Manager. It also offers a front-panel 1 x 1 MIDI port.
High-performance, 24-bit/96 kHz analog-to-digital and digital-to-analog converters ensure faithful reproduction coming and going, and all audio inputs and outputs are switchable between balanced (+4 dBu) and unbalanced (-10 dBV) operation to accommodate professional and consumer devices--and to work between them. Each 1/4-inch jack will accept either TRS or TS 1/4-inch plugs.
You may connect the output of a line-level instrument such as an electronic keyboard or instrument preamp, the output of a microphone preamp (a mic preamp is required for use with a microphone), or the output of a CD player or similar line-level device.
The Quattro lets you record at any sampling rate that your recording software will allow, up to 96 kHz at 24-bit resolution. You can also work at 16 or 24 bits with a sampling rate of 48 kHz or less. An ASIO control panel comes with your driver software, which lets you set the Quattro to its different operating modes. If you are not using ASIO or otherwise wish to monitor the signal at the Quattro inputs, a convenient direct/monitor switch bypasses the computer so you can directly monitor the input signal present at the Quattro.
When all four input and output stereo pairs (two input pairs and two output pairs) are enabled, the Quattro will operate in 16-bit mode at either the 44.1k or 48k sampling rates. With three stereo pairs enabled, i.e., either one input and two output pairs or two input and one output pair, the Quattro will operate at 48 kHz sampling rate or lower, and at either 24- or 16-bit. When one stereo pair is enabled and in 24-bit mode, the Quattro will operate at the 96 kHz sampling rate or lower.
You may connect the four outputs of the Quattro to a mixing console, or use two of the outputs for a stereo send to a monitoring system (power amp and speakers, or a home stereo), powered speakers, or a headphone amplifier.
The Quattro can be your only MIDI device, or it can be used in conjunction with as many other MIDI devices in your system as your music program allows.
Additionally, the Quattro can be used in conjunction with M-Audio's Omni I/O desktop recording system (not included). The Omni will add two microphone/instrument preamplifiers to the Quattro inputs, and a mixer to the Quattro outputs. The Omni will let you blend MIDI keyboards with audio tracks, add effects to the Quattro outputs, and control monitor and headphone levels while mixing down.
What's in the Box
Quattro USB audio interface, one (1) USB cable, one (1) 9V AC 1,000mA power supply, one (1) driver disk containing drivers and additional software, and a user's manual.
Note: It's usually possible to connect multiple devices to your USB port through the addition of a USB hub. The Quattro, however, requires all of the bandwidth that is available to the USB port, and therefore it is required that you plug the Quattro directly into your computer's USB port, and not into a USB hub with other USB devices. MIDI operation on Macintosh computers requires the OMS MIDI Manager from Opcode, which must be installed prior to the installation of the Quattro drivers.
