ROLAND VS-1824

Překlad částí pro optické rozhraní

12. DIGITAL Connectors (IN, OUT)

The VS-1824 accepts both coaxial and optical digital I/O connectors (conforming to S/P DIF).

IN 

This accepts a stereo digital audio signal. You can select either the coaxial input connection or the optical connection.

OUT

This outputs a stereo digital audio signal. You can use both the coaxial connector and the optical connector simultaneously, and each can carry a different signal.

VS-1824 umožňuje připojit oba koaxiální i optické I/O konektory (shodný s S/P DIF):

IN (Vstup) 

Tento přijímá stereo digitální audio signál. Můžete vybrat koaxiální nebo optický konektor.

OUT (Výstup) 

Tento konektor umožňuje výstup stereo digitálního audio signálu. Můžete použít oba, koafiální i optický současně, a každý může přenášet jiný signál.

Recording a Digital Source 

You can record digital signals from CD players, digital mixers such as the Roland VM-3100 or 7000 series, the Roland VS series, DAT machines and other digital sources.

• The VS-1824’s digital interface conforms to S/P DIF. When recording digital signals, be sure to use digital audio devices that utilize the S/P DIF standards.

Preparations for Recording a Digital Source 

1. Items Necessary for a Digital Recording:

* VS-1824

* CD player, DAT, VS-880, VM-3100, VM-7000 or other digital audio device

* Digital connector cable (coaxial or optical)

2. Making Connections

Connect the digital output connector of your audio device to the VS-1824’s DIGITAL IN connector. DIGITAL IN 1 is a coaxial connector, DIGITAL IN 2 is an optical connector. Use the appropriate connector for your digital device.

* DIGITAL IN 1 and DIGITAL IN 2 cannot be used simultaneously.

3. Match Sample Rates

The VS-1824 can record digital signals only when the sample rate of the song is set to the same sample rate of the digital source. When a drive is initialized, the default sample rate of a song is 44.1 kHz. If the sample rate of the source is other than 44.1 kHz, create a new song with that sample rate (p. 50). Many DAT players use a sample rate of 48 kHz. If you wish to create original audio CDs, you must use a sample rate of 44.1 kHz.

4. Set the Master Clock

In order to bring any digital signal into the VS-1824, you must synchronize the VS-1824’s internal clock with the digital signal from the your digital source.

a. Hold [SHIFT] and press [F5 (System)].

The System icon appears in the display. If the System menu icon does not appear, press [F6 (EXIT)].

b. Press [F1 (SYSPM)].

If “SYSPM” does not appear above [F1], press [PAGE] until it does, and press [F1].

c. Use

to move the cursor to “MasterClk.”

If “MasterClk” is not displayed, press [F1 (Prm 1)].

d. Use the TIME/VALUE dial

to select either DIGIN1 or DIGIN2, depending on whether you are using a coaxial connector or an optical connector.

MasterClk (Master Clock) This sets the VS-1824’s reference clock.

DIGIN1

Receives digital timing information from the

DIGITAL IN 1 connector (coaxial).

INT

Uses the VS-1824’s own internal clock.

DIGIN2

Receives digital timing information from the

DIGITAL IN 2 connector (optical).
