Art USBMix [4/12] Installation

INSTALLATION

1) Connect your audio device cables to the XLR or 1/4" TS CH1 INPUT or 1/4" TRS CH2-CH3

INPUT connectors. If you're using the CH1 INPUT with a 1/4" TS plug, next select the INST-Hi-Z

or LINE setting.

2) Connect the USB Mix USB TO COMPUTER connection on the back panel to the appropriate USB

input on your computer, using the supplied USB cable. You can also connect cables between the

MAIN MIX OUTPUT 1/4" TRS jacks and an analog audio input such as an amplifier.

3) Connect a pair of headphones to the MONITOR OUTPUT 1/4" TRS jacks if you want to monitor

the signal locally.

4) USB BUS POWER: No external power connection is needed. Power is supplied over the USB

connection. The front panel POWER LED will indicate that USB power is present when the USB

cable is connected to a live USB jack or to the included AC power adapter. If connecting to a

computer USB input, it is best to connect directly to the computer or, if using a USB hub, make

sure it is a powered hub, to ensure ample power for the USB Mix.

MONITORING WHAT YOU RECORD

The USB PLAYBACK TO CH2-CH3 pushbutton switch, when pushed in, provides a mix of the

preamp and computer signals. During typical operation either a local audio source is playing back, or

the computer is playing back, but not both at the same time. You can listen to either the preamp, or

the computer, without changing any settings. You will also be able to hear any computer alert signals

while you are listening to the record or tape if the alerts are also routed to the USB CODEC in your

computer’s sound setting control panel.

Some recording programs and computer systems provide what is called a “Play-Through” function.

This can be performed through software or hardware. When play-through is enabled, the computer

will output the audio that is being recorded, at the same time that it is actually being recorded. There

is a short delay, or latency, with this audio signal. There is also a potential for the computer’s audio

inputs and outputs to be inadvertently connected together thereby forming a feedback loop. This can

accidentally create very loud and disturbing sounds. Therefore, play-through is usually disabled by

default in both software and hardware.

If software/hardware play-through is enabled and the USB PLAYBACK TO CH2-CH3 pushbutton

switch is pushed in, then you will probably hear the original signal together with the computer audio

signal slightly delayed, thereby creating an echo effect. This is normal behavior, so while using the

USB PLAYBACK TO CH2-CH3 function, it may be preferable to leave play-through disabled.
