Do not place the AC adaptor cord near heat sources such as heaters or radiators, and do not excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a position where anyone could walk on, trip over, or roll anything over it. When removing the electric plug from the instrument or an outlet, always hold the plug itself and not the cord. Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can result in lower sound quality, or possibly cause overheating in the outlet. Unplug the AC power adaptor when not using the instrument, or during electrical storms. Before connecting the instrument to other electronic components, turn off the power for all components. Before turning the power on or off for all components, set all volume levels to minimum. Also, be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level. Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal components. Do not use the instrument near other electrical products such as televisions, radios, or speakers, since this might cause interference which can affect proper operation of the other products.
Before moving the instrument, remove all connected adaptor and other cables. When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, do not place vinyl, plastic or rubber objects on the instrument, since this might discolor the panel or keyboard. Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive force on the buttons, switches or connectors. Do not operate the instrument for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Do not place the instrument in an unstable position where it might accidentally fall over.

Welcome to the UW500

Thank you for choosing the Yamaha UW500 USB Audio/MIDI Personal Studio. The UW500 is a USB interface that enables simultaneous transfer of audio and MIDI data. Connect the UW500 to a computer that has a USB port and enjoy the powerful features of digital audio. Please read this owners manual thoroughly to make the best use of the UW500. After you read this manual, please keep it in a safe place for future reference.

Producing a clear sound

Usually, if you try to record audio using a computers audio input jack, computer noise is introduced and lowers the audio quality during the analog-to-digital conversion. The UW500, however, converts analog input signals into digital, which enables you to record clear sound to your hard disk.
The included software supports a musical production environment
Using the included software, XGworks and TWE facilitate hard disk recording. Even without external tone generators, you can play both audio data and MIDI data simultaneously using SoftSynthesizer S-YXG50.

Easy Hot Swap Connection

With a USB connection, you can connect and disconnect the USB cable while the power to the computer is on. You can also use the unit as soon as you install the driver.

USB Fast Data Transfer

USB connection enables a quick response from any connected devices during simultaneous audio and MIDI data performance. USB USB is an abbreviation for Universal Serial Bus. It is a serial interface for connecting a computer with peripheral devices, and enables much faster data transfer (12Mbps) compared to conventional serial port connections. Also, it allows hot swapping (connecting peripheral devices while the power to the computer is on).

Notes on USB

Dont turn the power to the UW500 on or off, or connect or disconnect a USB cable under any of the following conditions. Otherwise, the computer may lock up or UW500 functions may be disabled: The computer is checking the device or loading the driver. The computer is starting or quitting the OS. The computer is in Save Energy (Sleep) mode or canceling the mode. The audio/MIDI application is started. Also, dont perform any of the following operations. Otherwise, the computer may lock up or the UW500 functions may be disabled: Do not frequently turn on and off the power to the UW500 or connect and disconnect the cable. Do not place the computer in Save Energy (Sleep) mode or cancel the mode during audio/MIDI data transfer. Do not connect or disconnect the USB cable while the UW500 is on. Do not turn the power to the UW500 on or off, start the computer, or install the driver while a large quantity of data is being transferred.
Notes on musical copyrights
The UW500 supports SCMS (Serial Copy Management System) to protect the copyrights of music software. When you digitally copy data from CDs, or other music software purchased from stores, to your own media (such as MDs), information regarding digital recording generation is also recorded. If you route the recorded data to the DIGITAL IN jack, the data cannot be recorded on the computer. Use analog inputs (INPUT 1-3 jacks) to record data on the computer.

This knob has two functions. It switches the power on and off (stand-by) each time a click sound is heard when you turn the knob When the power is on, the knob enables you to adjust the UW500s overall volume. Note that the OUTPUT knob setting does not affect the output at the DIGITAL OUT jack and the input at the AUX IN jacks on the rear panel.
Even when the power is off (standby), a small current ows through the unit. If you plan not to use the UW500 for a long period of time, be sure to remove the power adaptor from the AC outlet.

H USB LED

The LED lights up in red when the power is turned on to the UW500. It lights up in green when the computer is connected to the UW500 correctly. It ashes in green when the UW500 transmits or receives MIDI signal. The LED lights up in orange if the INPUT SELECT switch is set to TRACK DOWN (page 15). The LED ashes in orange if the sampling frequency of the signal input at the DIGITAL IN jack is not appropriate. In this case, select the correct frequency option in the application on the computer according to the sampling frequency of the input signal. The LED ashes in red and green alternately when the copyrighted signal is input at the DIGITAL IN jack. The signal cannot be recorded on the computer (page 8).
