Operation manual SYSRACK-TGX

Introduction
The SYSRACK-TGX, developed by TWAUDiO, includes a Dynacord TGX10 power amplifier
as well as the new LED illuminated APL7 TGX connection panel, all combined in the new
Rack4TGX.
TGX 4-channel live sound amplifiers from Dynacord are one of the most powerful on the
market and represent the pinnacle of pro audio electronics engineering. Along with unprece-
dented power density, they offer Dynacord’s signature audio quality, advanced reliability and
power efficiency.
The APL7 connector panel provides all of the amplifier‘s connections at the front of the
SYSRACK-TGX. The integrated and switchable LED strip ensures a clear overview of the
panel even in difficult lighting conditions.
The panel layout follows the logical signal flow through the amplifier with a power, network,
audio input and output section. The two network ports provide the ability to use the amplifier
in a fully redundant network configuration supporting the latest standards in audio-over-IP
protocols with the OMNEO IP interface for Dante® and AES70.
The panel features the TGX series‘ ability to buffer digital audio signals when multiple ampli-
fiers are connected in parallel. The AES/EBU input signal is latency-free processed via an
active circuit in the amplifier.

4.1 Setup
The SYSRACK-TGX should be used in horizontal orientation.
Please note that due to the weight of the SYSRACK-TGX, two people are required to set up
the system.
4.2 Handling
The SYSRACK-TGX has a sliding lid on the front that allows easy access to the devices.
To open the lid, follow these steps:
1. Open the latch on the bottom of the lid.
Figure 4.2.1 - Unlock the lid
WARNING

2. Open the lid.
3. Slide the lid into the SYSRACK-TGX.
Figure 4.2.3 - Slide the lid into the SYSRACK
NOTE

12
When installing the power amplifier, ensure a sufficient ventilation.
Never block the amplifier‘s ventilation slots. Keep the ventilation slots free of dust to ensure
proper airflow.
4.3 Installation
Figure 4.3.1 - Minimum distance
0,6 m
0,6 m
When installing the SYSRACK-TGX, be sure to maintain a minimum distance of 0.6m at the
front and rear. This minimum distance ensures sufficient ventilation of the SYSRACK-TGX.
Also ensure that the sliding lid is fully open and slid into the rack during operation.
Do not use the power amplifier in direct sunlight or near devices such as heaters, stoves or
other sources that emit heat.
Do not use the amplifier in an environment with temperatures below 5 °C or above +40 °C.
For a fixed amplifier installation in a dedicated control room that has a central air cooling sys-
tem or air conditioning, it may be necessary to calculate the maximum heat dissipation.
Without sufficient ventilation, the correct functionality and operational safety of the amplifier
cannot be guaranteed. Insufficient ventilation can cause damage to the product.

4.4 Transport
Position a maximum of four SYSRACK-TGX on top of each other on a dolly. Make sure that
the setup is securely positioned so that it can‘t tip over.
Fix all SYSRACK-TGX with a lashing strap with a ratchet to the dolly!
Make sure that the lashing strap is pulled tightly and twist-free around the stack.
Do not put the lashing strap over the front lids of the SYSRACK-TGX.
When pushing, moving and transporting several SYSRACK-TGX on one dolly, please note
that the center of gravity is higher, which increases the risk of tipping.

4.6 Internal wiring
The SYSRACK-TGX is pre-wired and provides all of the amplifier‘s connections on the front
of the rack. It includes an APL7 connection panel specially developed and designed for ope-
rating a four-channel power amplifier of the Dynacord TGX series.
The SYSRACK-TGX is designed for operation in larger speaker systems and therefore allows
for quick and easy cabling of multiple racks. The panel combines all connections for the
power amplifier, the power connector, audio and network (OMNEO, Dante®). The panel has
integrated and switchable LED lighting.
Only clean the rack, the sliding lid, all other parts and the included devices with a dry cloth!
The rack can be cleaned from the outside with a light brush.
Information about worldwide service and spare parts can be obtained from the TW AUDiO
service department. E-Mail to: [email protected]
4.5 Service and maintenance
The panel is designed for use in the SYSRACK-TGX from TWAUDiO and should not be used
for other purposes outside the rack.
The panel is not protected against dripping, spraying or splashing water, IP20.
CAUTION

4.7 Mains voltage
Please note that there is a risk of electric shock or fire if the mains cable or power connector
is damaged!
The SYSRACK-TGX must only be operated via a mains power supply with a safety ground
connector. Do not disconnect or cover the safety ground connection of the power cable.
Replace the mains cable immediately if the cable or connector is damaged!
Ensure that the power connector is only plugged and unplugged if the device is free of vol-
tage.
Make sure that the specified supply voltages are provided by the power grid. There is a label
with safety instructions on the backside of the rack.
Mains voltage 100 - 240 V ~ 50 - 60 Hz
Rated power consumption 1200 W
The Powercon connector in the APL7 connection panel is used to connect to the supply
network. A corresponding mains cable must be ordered separately.

4.8 Network
The network socket with the label PRIM represents the connection of the primary network.
The network socket with the label SEC represents the connection of the secodary network.
Please note that the use of high-quality cables is essential for reliable operation of the
SYSRACK-TGX.
At least the CAT5e classification is required for network cables. CAT6 or higher is recommen-
ded.
The SYSRACK-TGX allows three different network modes.
1. GLITCHFREE (standard amplifier configuration) – Dante®/OCA on two separate networks
in Primary/Secondary configuration.
2. RSTP - The Rapid Spanning Tree Protocol enables closed-loop cabling in the network
configuration. In case of network failures or in case of a link failure, the network is recon-
figured to the remaining branch. This switch is typically characterized by a short audio
interruption.
3. TRANSPARENT – The network chip in the amplifier works as a switch. This allows several
amplifiers to be connected in serial. Closed-loop cabling must be avoided!
NOTE

Operation manual SYSRACK-TGX
17
A failure of a device in a serial network (daisy chain) will also affect the connection of the fol-
lowing devices. If one device fails, the subsequent devices are also no longer connected to
the network.
In the TRANSPARENT network mode, several racks can be wired serially.
Figure 4.8.1 - System cabling network mode TRANSPARENT
In GLITCHFREE network mode, the rack is connected to two independent networks (primary
and secondary). This structure is redundant for the control and audio signals via OCA and
Dante®.

For reliable operation, especially of larger amplifier configurations with Dante®/OCA, a redun-
dant network topology and cabling is always recommended.
If no or only one Dante® audio signal is used as an input source, signal redundancy can also
be implemented via the digital AES/EBU or analog inputs.

4.9 Audio inputs
The APL7 connection panel provides the input (IN) sockets and the associated link (LINK)
sockets for four digital AES3 and four analog inputs. The sockets are designed as
3-pin XLR connectors.
Input sockets 1 and 3 are connected in parallel to their corresponding link sockets.
The input sockets 2 and 4 are used for both digital and analog input signals. The switching
between analog and and digital inputs is done internally in the amplifier. The AES3 inputs are
buffered when the amplifier rack is connected to power.
Figure 4.9.1 -
Passive link of the input sig-
nal (inputs 1 and 3)
The link sockets allow and easy wiring of several SYSRACKS-TGX without an additional sig-
nal distribution. The input side is always terminated. The output side requires no additional
termination. In case of a mains power failure or an analog signal input the active buffering is
bypassed and the signal is forwarded without processing.

Figure 4.9.3 - Wiring of several SYSRACK-TGX with APL7
Due to the dual purpose of the input sockets 2 and 4, either digital or analog signals can be
used as a source. This can lead to the fact that certain combinations of signal routing cannot
be selected as a FAILOVER source in the Sonicue remote control software.
A redundancy from AES/EBU (DEFAULT) to analog (FAILOVER) could still be achieved by fee-
ding the AES signal via input socket 4 and the two analog signals via input sockets 1 and 2.
The DEFAULT and FAILOVER inputs must be defined accordingly in the Sonicue remote con-
trol software or on the amplifier‘s front panel.
For AES3, cables with a characteristic impedance of 110 Ω is recommended.
