4 CHANNEL OUTPUT
NOTICE!
The 4 CHANNEL OUTPUT connector is only intended as an
interface to a rack panel or to loudspeaker multicores and
breakout adapters.
Do not connect any loudspeaker cabinet, neither passive nor active
systems, to this connector, otherwise there is a risk of damaging the
loudspeaker components or the amplifier.
The centered NL8 connector carries the output signals of all four
amplifier channels with the following pin assignment:
1+/— = Channel A pos. / neg.
2+/— = Channel B pos. / neg.
3+/— = Channel C pos. / neg. 4+/— = Channel D pos. / neg.
5.2.4 Network connections (PRI/SEC)
NOTICE!
Only shielded network cables (STP) must be used!
The device allows standard remote control via the d&b Remote
network using the d&b R1 Remote control software or the
integrated Web remote interface.
For this purpose, use the upper RJ45 (PRI) connector socket
(1 Gbit/s/100 Mbit/s – peer-to-peer) requiring star topology
network wiring. Daisy-chaining is not supported.
Note: The bottom RJ45 connector socket (SEC) is not enabled
but is reserved for future feature implementations.
LED indicators
The two LED indicators above the respective connector in use
indicate the following states:
Green
Illuminates permanently when the device is connected
to an active network and flashes as long as a data
stream is transmitted.
Yellow ▪ Is off when the speed is 100 Mbit/s.
▪ Illuminates permanently when the speed is
1 Gbit/s.
