M-Audio DIO2448 Инструкция по эксплуатации онлайн [11/24] 18994

Below are descriptions of each control panel function. While reading this

section, it might be helpful to reference the DiO 2448 block diagram in the

‘About the DiO 2448’ section of this manual.

SPDIF-OUT Source

: This switch determines which audio stream will be

transmitted at the DiO 2448 S/PDIF outputs. Its setting affects only the

S/PDIF outputs and not the Analog outputs. Choose “SPDIF-IN” to monitor

the DiO 2448’s active S/PDIF input directly. In this mode, the S/PDIF

outputs will not receive audio from your software programs. Choose

“WAV (software)” to allow software audio playback to be transmitted from

the S/PDIF outputs. In this mode, you will not be able to monitor the

S/PDIF inputs at the S/PDIF outputs.

Monitor SPDIF-IN at ANALOG-OUT

: Selecting this option will mix the

audio data from the active S/PDIF input to the Analog outputs for

monitoring. The analog monitor level is not individually controllable

(whereas the WAV and CD-ROM monitor levels have individual controls),

but may be set via the Master Volume fader in the Windows mixer.

SPDIF-IN Format

: Sometimes the DiO 2448 may have difficulty locking to

certain inverted S/PDIF input signals. This control allows the DiO 2448 to

compensate for this condition by “re-inverting” the signal. The default

setting is “Normal.” However, set “Inverse” if you ever have difficulty

recording or monitoring the incoming S/PDIF signal. You should only have

to set this control once for a problem signal – the driver will automatically

remember the SPDIF-In Format each time the system restarts.

IMPORTANT: In rare cases the DiO 2448 may have difficulty

locking to certain inverted S/PDIF input signals. The symptoms of

this will be extremely noisy recording and/or monitoring of the

S/PDIF inputs. If you encounter one or both of these symptoms,

go immediately to the DiO 2448 Control Panel and verify the

SPDIF-IN Format setting.

Analyze: Instead of manually setting the SPDIF-IN Format, you may choose

to automatically analyze the incoming S/PDIF signal and make the proper
