2.2.2 Digital audio connections
2.2.2.1 AES-3
The processor includes an AES-3 input and output. When
using the digital input, it is also convenient to connect
the analog inputs. If the signal is lost at the main input,
the processor automatically switches to another input
that has a signal. The default entry is selected from the
"Inputs" menu, as explained below.
S/PDIF: A S/PDIF signal can be connected to
AES-3 by using an S/PDIF-to-AES3 adapter. The
figure shows a compact adapter with XLR and
BNC connectors.
The AES-3 output is balanced, using a male XLR. The
connections are the following:
XLR Signal
1 GND
2 AES3 (1)
3 AES3 (2)

2.2.2.2 Incoming streaming port (optional)
The port "Ethernet AoIP"
- 11
allows receiving an incom-
ing digital audio streaming, used for transporting audio
from Studios to Transmitting Plant. See "2.8 - AoIP Con-
nection". RTP and Shoutcast/Icecast servers are sup-
ported.
From Studios, the RTP streaming can be encoded using
mixing consoles Solidyne DX816, series 2600, series
UNIDEX or the Solidyne ADA102 link. Equipment of others
brands also can be used. For details please see “SECC-
TION 5 – Models with the optional AoIP”
2.3 MPX outputs
The 542APC features dual MPX output
- 12
, with indepen-
dent level adjustment.
The output connectors are BNC type. 75-ohm coaxial ca-
ble (RG59 standard on CCTV) can be used for the con-
nection. The length of this cable should be kept less than
25 meters.
When entering the transmitter via MPX, make sure that
the internal pre-emphasis network of the transmitter is
switched off (flat response 20 - 100 kHz). The pre-em-
phasis on 542APC is fixed at 50 or 75 microseconds.
It is very important to have a good design of ground
connections. In case of doubt, contact Solidyne describ-
ing the equipment and the connection diagram used.
2.4 FM antenna
The internal receiver allows you to tune the transmis-
sion of any station and view the modulation level, audio
levels, RDS data and other transmission issues (see
“3.9 FM analyzer monitor”).
The BNC connector labeled "Receiver FM ant"
- 13
pro-
vides connection to the antenna of the internal FM re-
ceiver. From factory two antennas are provided:
•
Telescopic mini-antenna: Is used for the most of sit-
uations.
•
BNC micro-antenna: When the RF field intensity is too
high, the gain of telescopic antenna can cause the
saturation of the receiver. The indicator RF LVL (FM
Monitor Analyzer) is stuck at the maximum value 100
dBuV. In this case, use the BNC-terminal.
Depending on the installing conditions (location of the
equipment, distance to the transmitting plant, etc.), a
wired antenna (not supplied) installed outside the build-
ing may be necessary.
2.5 IP remote control
The ETHERNET port
- 11
allows the connection of the
542APC to a LAN to access the WEB Control Panel. The
network router assigns an IP address to the processor
(DHCP). This IP allows access to the internal web
pages of the processor, using a computer connected to
the same LAN and a WEB browser (Google Chrome is
recommended).
For details on use see “3.4 – Remote control via web” .
