Component application
Digital audio matrix board
The Cerberus PACE Compact audio matrices process audio signals from the digital network,
the internal digital memory (flash), the micro SD card, and the analog audio inputs. The
audio matrices automatically digitize analog signals, so they can be processed further. Each
audio signal is assigned to an audio channel. A Cerberus PACE Compact audio matrix can
manage up to 255 audio channels.
Cerberus PACE Compact audio matrices are standard network participants. Audio matrices
are connected to the network using Ethernet switches.
The parameters for audio transmission within the network are configured using the 'PACE-
Design' system software. The audio matrices have sampling frequencies of up to
48 kHz / 24 bit to ensure compliance with the most stringent audio quality requirements. The
Cerberus PACE Compact audio matrices transmit up to 64 audio channels simultaneously
within the network. The constant latency of 4.6 ms presents in audio signals from the analog
input, e.g., a microphone, up to the point of being converted back to analog and output at the
speaker lines. This very slight delay allows for Cerberus PACE Compact systems to be used
in 'pro sound' applications.
The network also transmits all the control signals simultaneously as the audio signals.
The Cerberus PACE Compact audio matrices PC1001-A3 and PC1002-A3 monitor the
correct function of the installed amplifiers. In case of a fault, they can switch to the installed
backup amplifiers.
The Cerberus PACE Compact audio matrices PC1001-A3 and PC1002-A3 monitor the
connected speaker lines for open lines, short circuits and ground faults. The monitoring can
be conducted via speaker line impedance supervision or via EOL elements PCA2004-A1.
Speaker loops with short circuit isolators PCA2005-A1 can be connected to the audio
matrices PC1001-A3 and PC1002-A3.
Ethernet switches
Ethernet switches are used to connect individual Cerberus PACE Compact network
components, such as Cerberus PACE Compact system and call stations. The Ethernet
switches can be connected to a 'PACE-Net' network of up to 1350 network participants.
The Cerberus PACE Compact network components feature two independent network
connections. These Ethernet connections combined with Ethernet switches can be used to
build a fully redundant network.
All Cerberus PACE Compact Ethernet switches feature standard Ethernet sockets (RJ45) for
the connection of Cerberus PACE Compact network components. Adapters can be fitted to
create further interfaces for maximum flexibility in network cable selection. Users can choose
between 100 Mbit/s Ethernet and various fiber-optic adapters in any frequency range, from
multi-mode to single-mode.
Media converter
The media converter converts a CAT5 copper-based Ethernet section to fiber-optic based
Ethernet section.
