Settings on your computer

Here are a few basic points to help you set up your computer for best performance with audio applications.

- Do not run other applications. You will probably use your computer for applications other than audio, but we recommend that you avoid running other applications at the same time you are running audio programs. Processing digital audio places a considerable load on your computer.

This means that if you are running other applications (especially graphics or

Internet tools) at the same time as your audio application, the processing may not happen fast enough.

• Certain devices such as network cards or WinModems can cause conflicts with USB processing. If you experience such a conflict, you can use the Device Manager to temporarily disable the offending device.
• If your computer has an IDE hard disk, enabling Direct Memory Addressing (DMA) will improve performance. In Windows XP, this is enabled by default.

4 - Control panel settings

Overview

The Control Panel lets you make various settings for the US-144's functionality.

The Control Panel is divided into the following two sections.

Status section

This shows the current status of the driver and the connected hardware.

You cannot edit the settings from this section.

Setting section

Here you can edit the various settings of the driver.

Driver settings

Audio Performance

The US-144 driver temporarily stores input and output audio samples in buffers.

The Audio Performance setting lets you adjust the buffer size. The Lowest Latency setting is the minimum buffer size, and the Highest Latency setting is the maximum buffer size.

A smaller buffer size will reduce the delay when monitoring the input signal, but will require your computer to perform the pro-

cessing faster. If the processing does not occur in time (e.g., if other system operations are occurring), you may hear clicks, pops, or dropouts in the audio signal.

A larger buffer size provides more safety against such problems caused by other system activities, but will produce greater delay when monitoring the audio signal.

The US-144 lets you select the buffer size that works best for your system.

Sample Clock Source

You can set the clock source to Automatic or Internal.

Automatic (default): If a signal is being input to the DIGITAL IN jack, its clock will be used. If no signal is being input to the

DIGITAL IN jack, the US-144's internal clock will be used.

Internal: The US-144's internal clock will always be used.

4 - Control panel settings

Digital Output Format

This lets you choose either AES/EBU or S/PDIF as the digital output format. Many professional devices use an XLR connector for AES/EBU. Special adapters may be purchased to convert between a digital audio RCA connector and digital audio XLR connector.

USB 1.1 Mode Input Selection

This item is shown only if the US-144 is connected to a USB 1.1 port on the host computer or to a USB 1.1 hub. In this case, the US-144 functions as a 2-in / 2-out audio device, rather than the usual 4-in / 4-out. You can choose either Analog or Digital as the input source.

USB connections

Using the included cable, connect the US-144 to your computer as shown in the illustration.

IN L IN OUT R USB Computer

NOTE

Some USB devices access the USB bus frequently. To avoid dropouts and clicks in the audio signal, we strongly recommend that you do not connect other USB devices to the USB bus used by the US-144.

USB keyboards and mice are exceptions to this, and will probably not cause problems.

Audio connections

Connect the output signal of your mic, guitar, keyboard, or other audio device to the US-144, where it will be converted into digital audio and sent via USB to your computer. Connect the output of the US-144 to your speakers (via an amp) or headphones, so you will be able to monitor the audio signals coming into the US-144 or being produced by your computer.

NOTE

The US-144 has two input channels (L, R), with a MIC IN jack (XLR) and LINE IN jack (1/4" phone jack) provided for each channel. Do not connect signals to both of these analog input jacks at the same time. If both are connected, the signal will not be correctly input to the US-144.

Mic

Connect your mics to the MIC IN (L, R) jacks (XLR). If you are using a condenser mic that requires phantom power, turn on the phantom power.

If you're using a condenser mic PHANTOM OFF ON
