Before Use

Placement of the unit

• Avoid placing it in high temperature environments such as in direct sunlight or close to a source of heat. Also, do not place the unit on an amplifier or any other device that generates heat. Doing so may cause discoloration, deformation, or malfunction.
• When the unit is turned on, switching on the TV may cause lines to appear on the TV screen, depending on the wave frequency of the T V broadcast. This is not a malfunction in the unit or the TV. If you see such lines, place this unit far away from the TV set.

Maintenance

If the surface of the unit gets dirty, wipe it with a soft cloth or use diluted mild liquid soap. Do not use thinner, benzene or alcohol as they could damage the surface of the unit.

For safety, disconnect the power cord from the socket before cleaning.

Sound Etiquette

What is music to you may be noise to others. Even a little sound can be clearly heard on a silent night. Low sound passes through floors and walls easily, and may annoy others unintentionally.
Enjoy music at an appropriate volume, close the window, or use headphones to ensure a pleasant living environment.

Playing Back Music Files Stored on a Computer

Installing dedicated TEAC driver software on a computer

To play back music files stored on a computer with this unit, you must download dedicated driver software from our website and install it on the computer before making your USB connections.

<Website address for downloading the dedicated driver software>
http://www.teac.co.jp/audio/software_teac_e.html

This unit can be connected by USB and used with a computer running Windows XP, Windows Vista, Windows 7, Mac OS X 10.6.4 or later. Use with a computer running a different operating system cannot be guaranteed.

Note
Install dedicated TEAC driver software before connecting to the computer by USB.
If you connect the unit with the computer before installing the driver, it will not function properly. Moreover, when using Windows XP, the computer could become remarkably slower and require restarting in some cases.

• For details on how to install dedicated driver software, see our website.
• Depending on the computer's hardware and software configuration, the unit might not function even when used with one of the operating systems listed above.

Connect to the computer using HIGH SPEED asynchronous mode.
Sampling frequencies that can be transmitted are 32 kHz*, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz.
* If the sampling frequency of the input signal is 32 kHz, the frequency indicators do not light up, but the input indicators do.

If the connection has been made properly, "TEAC USB HS ASYNC AUDIO" will be selectable as an audio output destination.

• In asynchronous mode, jitter that occurs during transfer is suppressed because the clock signal of this unit is used for playback of the audio data transmitted from the computer.

Playing back music files stored in the computer

1. Connect the unit to the computer using a USB cable.
   
   • Use a cable with a connector that fits the USB port on the unit.
2. Turn the computer power ON.
   • Confirm that the operating system has started properly.
3. Press the POWER button to turn the unit power ON.
   
4. Press the SOURCE button repeatedly to select "USB".
   
5. Start playback of the music file on the computer.
   Even better sound quality can be achieved by setting the volume on the computer to maximum and using the amplifier connected to this unit to adjust the volume.
   Set the volume of the amplifier to the minimum at the beginning of playback and gradually raise the level.

• The computer and this unit cannot be used to control each other.
• When playing back a music file using the USB connection, do not attempt any of the following operations. Doing so could cause the computer to behave irregularly. Always stop music playback software on your computer before doing any of the following:
  • Disconnecting the USB cable
  • Turning the unit's power OFF
  • Changing the input source
• When playing back a music file using the USB connection, computer operation sounds will also be played through this unit. To avoid this, make appropriate settings on the computer.
• If you connect this unit with the computer or you set this unit's input to "USB" after starting music playback software, music files might not play back properly. If this occurs, restart the music playback software or reboot the computer.

Troubleshooting

If you experience any problems with the unit, please take a moment to look through this chart before asking for repairs. If you still have a problem, contact your dealer or TEAC customer service/technical support (stated on the back cover).

Since this unit uses a microcontroller, external noise and other interference can cause the unit to malfunction. If this occurs, unplug the power cord, wait for a while, and then turn the power back on to restart operations.
