M-Audio Delta RBUS Инструкция по эксплуатации онлайн [13/60] 19013

connector is a wordclock output which may be used to synchronize other

digital devices to the Delta R-BUS board. Wordclock is a sampling clock

signal which automatically operates at the present Delta R-BUS sample

rate, whether that sample rate is derived from the Delta R-BUS’s internal

clock, S/PDIF input, or R-BUS internal or external input.

Analog jacks on the Delta R-BUS breakout cable, two for input and two

for output, are RCA phono type female jacks. Although the RCA jacks

typically allow connection to unbalanced (typically consumer) line level

connections, +4dBu level unbalanced equipment may be connected to the

Delta R-BUS’s RCA jacks. However, sometimes +4dB signals may be too

hot for these analog inputs. Consult the user guide for your particular

device. On the analog outputs, the Delta Control Panel software provides

line level switches between -10dB and -4dB (labeled “Consumer”). These

software switches allow you to adjust your stereo output signal to the line

level of the receiving device.

NOTE: In order to preserve its high dynamic range and

minimize distortion, the Delta R-BUS does not have

microphone pre-amplifiers built into it. Therefore direct

connection to a microphone is not recommended. Instead

run the microphone signal through a microphone pre-amp

(such as the M Audio"DMP3™") and then connect the pre-

amp output to the input of the Delta R-BUS.

The Digital Monitor Mixer

The Delta R-BUS PCI Audio Card has a hardware digital audio mixer

built into its PCI controller chip. It accepts digital audio streams from all

hardware inputs and all outgoing software audio devices, mixes them

with 36-bit internal precision and then provides the mixed output to one

or more locations. For the purpose of monitoring, the output of the mixer

may be routed to the pair of Delta R-BUS analog outputs and the S/PDIF

digital output simultaneously (SP/ANA stereo pair). The output of the

mixer may also be routed to the Delta R-BUS Audio Card’s R-BUS OUT1

and OUT2. At the same time the mixer may be used for stereo mix-down,

with the mixer’s output recorded into the user’s application software.

The digital audio mixer is configured and controlled by the included

Delta Control Panel Software.

The Patchbay / Router

In addition to the built-in monitor mixer, the Delta R-BUS PCI Audio Card

includes an output patchbay/router. The patchbay/router allows each

output (analog or digital) to be connected to a variety of input sources. The
