Digital Interface; Installation - Genelec 8130A Operating Manual

System
The Genelec 8130A Digital Monitoring
System has a 192 kHz/24 bit digital audio
interface allowing you to input digital audio
signals straight into the loudspeaker to pre-
cisely and directly monitor their audio con-
tent.
The 8130A supports all the same modes of
operation as the analog Genelec 8030A. You
can use it with a subwoofer. You can use it in
surround audio systems. You can even use
the 8130A as an analog loudspeaker.
Due to its compact size, integrated con-
struction, excellent dispersion and precise
stereo imaging, the 8130A is ideal for near
field monitoring, mobile vans, digital audio
workstations, broadcast and TV control
rooms, surround sound systems, home stu-
dios, multimedia applications and computer
soundcards.
Integrated construction
As the digital interface and amplifiers are
built into the loudspeaker enclosure, the only
connections required are the mains supply
and the input signal, making the 8130A very
easy to set up and use.

Digital interface

The digital audio interface comprises a dig-
ital audio receiver and a digital-to-analog
converter (D/A converter). The 8130A can
be used with sampling frequencies up to 192
kHz and word length up to 24 bit. The D/A
converter has high resilience to clock jitter
and excellent linearity.

Installation

After unpacking, place the loudspeakers
in their listening position, taking note of the
listening axis (see figure 3). Ensure that the
mains switches are set to "OFF" and the
volume controls turned fully counterclock-
wise. Power up the system only after all the
connections have been made and turn the
volume up carefully.
Signal connectors
on the 8130A
The 8130 has three XLR connectors on the
back panel (see figure 1):
DIGITAL THRU AES/EBU
This male XLR connector delivers a buffered
bit-to-bit copy of the digital input signal. The
connector can be used for daisy-chaining
up to eight 8130A's together in digital mode.
When the input signal is analog, there is no
output from this connector.
DIGITAL IN AES/EBU
ANALOG IN
This female XLR connector accepts digital
AES/EBU or analog line level signals. The
Genelec 8130A detects analog or digital sig-
nals and directs them to the right signal paths.
In cases where the 8130A is presented with a
dual-wire/single channel signal, detection is
again automatic and the correct digital input
mode is selected.
ANALOG OUT
This male XLR connector delivers a full-band-
width analog version of the digital or analog
audio coming to the input connector. It can be
used for daisy-chaining up to eight 8130A's
together in analog mode or for connecting a
Genelec 7050A subwoofer. In digital mode the
signal level from the "ANALOG OUT" connec-
tor is controlled by the volume control knob
on the front panel and the "SYSTEM LEVEL"
switches on the back panel, in analog mode by
the volume control knob only.
