This setting is enabled or disabled for all tracks of the music library centrally following the
path SETTINGS & SPECIALS > GENERAL SETTINGS > SOUND > DYNAMICS COMPRES-
SION. There are four modes available:
• OFF: Pressing the relevant soft key switches dynamics compression off.
• NIGHT MODE: This setting is recommended for quiet environments, like listening to
music in your apartment while showing consideration for the sleep of your neighbors.
• LOUD ENVIRONMENT: This setting should be used in places with lots of environmen-
tal noise.
• EXPERT MODE: Here acoustics experts can fine tune the parameters of dynamic
compression parameters by themselves. The dynamics compressor limits the range of
dynamics of the audio material. When the defined threshold level is reached, the com-
pressor compresses the signal according to a certain ratio. Attack time and release
time define how fast the compression begins and ends:
• METHOD: This method defines how the transition between compression and
non-compression is done. SOFT KNEE is recommended for instrumental sound,
HARD KNEE for voices, suppressing “pop” sounds in talking and singing.
• THRESHOLD: This is the trigger level for the compression, it can vary between
–60 and –6 dB.
• RATIO: This setting defines the magnitude of the compression, the relation
between input and output level. E.g. a ratio of 4:1 means that an increase of
100% of the input level beyond the threshold only leads to a 25% increase of the
output level. The ratio can vary between 1 and 6.
• ATTACK: This determines the interval the compressor waits until it reacts. This in-
terval should be not to short, to avoid pumping effects. Attack can vary between
1 and 50 ms.
• RELEASE: This sets the interval the compressor should go on after the input level
falls below the threshold. Higher values of release give you smoother transitions.
Release can vary between 0.1 and 1 second (s).
3.2 Network Settings
A stand-alone OPUS is great for archiving and listening to music. But as a member of a
home network with additional clients or connected music servers or PCs it can do much
more. Your OPUS is fully enabled for wireless or wired communication. Before getting
started please make sure that the network settings of all other devices such as Pcs/Mac are
set to “Obtain an IP address automatically” or “DHCP”. This is especially important if you
are using a portable computer alternately at home and at the office and its networking set-
tings is configured automatically at the office.
The following settings define OPUS’ properties for integrating with other computers in a
local area network, wired and wireless.
Connection Ports
The antenna for wireless communication (WLAN) is on the back of the OPUS, the plugs for
Ethernet cabling beneath.
• OPUS provides four 10/100BaseT Ethernet ports on its back, which are configured as
a general switch. The ports automatically adapt to the used bandwidth and cabling.
Looking for cross-over cables is not necessary.
• OPUS can be used as a WLAN station according to 802.11g (54 Mbit/s). This
standard is backwards compatible with 802.11b (11 Mbit/s). Depending on the mode
OPUS is configured to it is acting as a WLAN client or an Access Point.
Network Configuration
As part of the SETTNGS & SPECIALS > NETWORK menu, you manage the CONFIGURA-
TION if your OPUS as part of your home network. In difference to the other settings, as
added safety after every change of the network configuration you must confirm them so
they are activated. You activate the new settings by pressing the soft key ACTIVATE as part
of the NETWORK menu:
• MODE: OPUS allows you to choose from these three operating modes:
• OLIVE MUSIC NETWORK: OPUS acts as central switch, optional WLAN Ac-
cess Point, and DHCP server of the network (according to RFC 1918). It pro-
vides a DHCP service and distributes IP addresses to connected devices out of
192.168.72.0/24 range. The chosen settings must correspond to those used by
the other computers as they communicate with the OPUS.
• HOME NETWORK: A working local area network already exists and the OPUS
should act as a DHCP client and search the existing network for settings. Settings
on the OPUS must correspond to those of the existing home network for com-
munication to function properly.
• EXPERT MODE: As above with the home network, with the difference that you
enter the IP configuration manually.
• WLAN: For all modes the WLAN function can be enabled/disabled separately.
• NETWORK CONNECTION (only expert mode): Here two modes can be chosen:
