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

Certain devices such as network cards or

• WinModems can cause conflicts with USB processing. If you experience such a conf lict, 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.

Overview

4 – Control panel settings

The Control Panel lets you make vari settings for the US-144’s functionality.

The Control Panel is divided into the following two sections.

ous

Status section

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

You cannot edit the settings from this section.

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.

5 – Connections

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.

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.

The US-14 4 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.

7 – Troubleshooting

This chapter lists frequently asked questions related to recording with Cubase LE, with answers to these questions.

Q. I have finished making input settings, but the meter of the audio track is not moving.

A. Make sure that the monitor button of

the track is enabled.

Q. I would like to record two channels simultaneously for a stereo recording.

A. Before you record, press the stereo/

mono select button of the track so that the yellow indicator is lit. In this case, the track input is shown as In 1 + In 2 or a similar indication.

Q. I mixed-down a song that was three minutes long, but the result was only ten seconds long.

A. Make sure that the left and right locator

region is set to the entire range that you want to mix down.

Q. I cannot set the locator region to more than ten minutes.

A. The default setting is ten minutes.

From the Project menu, choose Project Setup and adjust the length of the project.

Q. I am trying to use the EQ, but it does not seem to do anything.

A. Check the VST channel settings etc. to

make sure that EQ bypass is not enabled.

TASCAM US-144 21

7 – Troubleshooting

Q. I performed a mixdown, but the automation and effects were not reflected in the mixdown.

A. In the Export Audio Mixdown dialog

box, make sure that automation and effects are enabled.

Q. I made a CD using the WAV file I mixed-down, but the speed is obviously different.

A. Could your project be set to 48 kHz?

If your ultimate objective is to create a CD, we recommend that you work in 44.1 kHz from the beginning.

To specify the sample rate, pull down the Project menu, choose Project Settings, and set the sample rate to 44,100 Hz.

Q. Using the ReWire protocol, can I record the incoming audio on a track?

A. In Cubase LE, ReWire tracks do not

have recording capability. You will have to export the audio data, and

then import it into an audio track.

Q. I have connected an audio source to the US-144, but cannot hear anything.

A. Make sure that the input level is raised

appropriately. If the input is analog, the green indicator will light when a signal is being input.

Make sure that the monitor (or headphone) level is raised, and that the connections are correct.

22 TASCAM US-144

Q. The sound is distorted. A. Make sure that the signal is not over-

loading. The ideal level is when the red indicator lights occasionally.
