Introduction

Features of the UA-30

Thank you for purchasing the UA-30. The UA-30 is a USB audio interface that can be connected to your computer via a single USB cable to allow highquality digital recording/playback of audio data.

Superb sound quality

Both optical and coaxial type digital input/output connectors are provided. Sampling rates of 44.1 / 48 kHz are supported, allowing zero-loss signal transfer with CD, MD (Mini Disc), or DAT.

As analog input/output jacks, the UA-30 provides RCA phono jacks as well as a phone jack that supports guitar/mic input levels. 20-bit AD/DA conversion ensures high-quality recording/playback, and sampling rates of 22.05 kHz / 44.1 kHz / 48 kHz are supported.

Easy connection to your computer via USB cable

The UA-30 requires only a single USB cable for connection to your computer. It uses a bus power supply in which power is supplied from your computer, so that an AC adaptor is not needed, making the UA-30 ideal for use even with notebook computers.

Cool Edit Pro LE included for audio editing freedom

Audio data transferred to your computer via the UA-30 can be edited and processed freely. You can apply numerous effects, including echo to make the sound more spacious and flanger to create modulation.

What is USB?

USB stands for Universal Serial Bus, and is a new interface for connecting various peripheral devices to a personal computer.

USB allows numerous peripherals to be connected by a single USB cable, and data can be transmitted at a rate much faster than the earlier serial ports. Peripheral devices can be connected or disconnected while the power of the computer remains on, and the computer will recognize these devices automatically. (Some peripherals may require settings.)

About copyright

Unauthorized recording, performing, broadcasting, sale, or distribution of works whose copyright is owned by a third party (CD software, video software, broadcasts etc.) is forbidden by law. Even if you use the UA-30 to violate the rights of a third party, Roland Corporation shall bear no responsibility for your actions.

Introduction

About SCMS

SCMS (Serial Copy Management System) is a function provided on consumer digital audio devices such as DAT and MD recorders to protect the rights of the copyright owner by prohibiting digital second-generation recordings from being made via a digital connection. If you record via a digital connection from a digital recorder that has SCMS, the SCMS data will be recorded together with the digital audio data. Digital audio data that contains SCMS data cannot be recorded again via a digital connection.

On the UA-30

When data containing the SCMS flag (such as data from an MD that was digitally copied from a commercial music CD) is input, the UA-30 will function as follows.

If input from the UA-30’s digital input connector:

The UA-30 cannot record this data to your computer

The audio will be output from the analog outputs (line output jacks, headphone jack)

If input from the UA-30’s analog inputs (line input jacks):

• Recording can occur normally

Regardless of the presence or absence of the

SCMS flag, data that is received at the digital input connector of the UA-30 will not be output directly from the digital output connector.

You will need to provide these items yourself

External amp, speakers, headphone, and mic are not included

External amp, speakers, or headphones necessary for listening to the sound output via the UA-30 are not included. Nor is a mic included for inputting sound to the UA-30. You will need to provide these items yourself.

Digital input/output cables for connecting the MD or DAT recorder are not included

Although you can use an MD or DAT digital recorder to perform digital recording, the cables for connecting the recorder to the UA-30 are not included. You will need to provide these separately.

Optical

These are digital I/O connectors for connecting optical cables. The digital I/O connectors for connecting coaxial cables are marked COAXIAL.

Sample rate

When audio is recorded digitally, the level of the sound is measured at fixed intervals of time, and the level is converted into digital data. The sample rate (sampling frequency) is what determines this time interval. CD and MD use a sampling frequency of 44.1 kHz, and DAT can also use a sampling frequency of 48 kHz. By setting this switch to match the sampling rate of the connected device, you can digitally record without diminishing the audio quality.

Before changing the position of the Sample

rate select switch or the

Recording input select

switch, you must exit all

applications including the

UA-30 D-Out Smoother

(p. 37). You should also turn down the volume of any audio amp system that is connected.
