1.3 Safety precautions
Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings
as well as for the connected speaker systems. High output voltages can damage or even
destroy the connected speaker systems, especially, when the amplifier is operated in bridge
mode. Prior to connecting any loudspeakers, make sure to check the speaker system’s
specifications for continuous and peak power handling capacities. Even if amplification has
been reduced through lowering the input level controls on the amplifier’s front panel, it is still
possible to achieve full power output with a sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at
the output connectors.
To protect yourself from electric shock, do not touch any blank speaker cables during
operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring
connected to these terminals requires installation by an instructed person or the use of
ready-made leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is
possible that during operation shock hazard voltages may be present at the taps of the
transformer.
Therefore, the taps have to be insulated sufficiently in accordance with applicable safety
regulations.

5 Installation
5.1 Mounting
TGX amplifiers are designed for installation in a conventional 19-inch rack case. Attach the
power amp with its frontal rack mount ears using four 20 mm screws and washers. If the rack
will be transported secure the amplifier at the rear. Failure to do so may result in damage to
the power amplifier as well as to the rack case. Attach the power amp using four case nuts
and screws. Brackets for securing the power amplifier in the rear are available as accessories
(RMK-15).
5.2 Mains power connection
Mains power connection (all countries except the USA)
The power amplifier receives its power supply via the MAINS connector. It is recommended to
use either the listed power cords or power distributions. Custom power cords using the
supplied connector have to be built from qualified personal following the safety and assembly
instructions. During installation, always separate the power amplifier from the mains. Connect
the power amplifier only to a mains network, which corresponds to the requirements
indicated on the type plate.
Mains power connection (USA only)
The power amplifier receives its power supply via the MAINS connector. Only the listed power
cords or power distributions shall be used. During installation, always separate the power
amplifier from the mains. Connect the power amplifier only to a mains network, which
corresponds to the requirements indicated on the type plate.

– Accessories, page 30
5.3 Power
The TGX power switch is located on the rear panel of the power amplifier. Press the switch
towards the label ON powers on the amplifier. Press the switch to the other side powers the
amplifier down. A soft start circuit compensates mains inrush current peaks and thus prevents
triggering AC mains fuse when switching on the amplifier.
Speaker system switch-on is delayed by approximately 15 seconds while the amplifier is
booting. During that time the speakers are decoupled by relays. The amplifier is ready for
operation when the display is showing the home screen and the amp icon is green.
5.4 Ventilation
As with all Dynacord fan cooled power amps, the airflow direction is front-to-rear. When
installing the power amp in a case or rack system, attention should be paid to provide
sufficient ventilation. Allow for an air duct of at least 100 mm x 330 mm between the rear
panel of the power amplifier and the inner wall of the cabinet/rack case. Ensure the duct
reaches up to the cabinets or the rack case’s top ventilation louvers. Leave room of at least
100 mm above the cabinet/rack case for ventilation. Temperatures inside of the cabinet/rack
case can easily rise up to 40 °C (104 °F) during operation of the power amp, it is mandatory to
bear in mind the maximum allowable ambient temperature for all other appliances installed in
the same cabinet/rack case.

Figure5.1: Power amplifier ventilation
Caution!
Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient
cooling/ventilation, the power amplifier may enter protect mode.
Keep ventilation louvers free from dust to ensure unhindered airflow.
Notice!
Do not use the power amplifier in direct sunlight or near heat sources, like heater blowers,
stoves, or any other heat radiating devices.
Notice!
Do not use the power amplifiers in an environment where temperatures are below 5 °C (41
°F) or exceed +40 °C (104 °F).
For fixed amplifier installations in a device control room that incorporate a central air-cooling
system or air conditioners, calculating the maximum heat emission may be necessary.

Caution!
Ensure you use proper cabling. TGX amplifiers are extremely powerful, bad cabling, such as
shortages can lead to equipment damages.
Also, ensure to observe the power handling specification for your loudspeaker system and
adjust if required the DSP limiters accordingly.
6.4 Audio inputs
Audio input connectors on TGX amplifiers are four XLR-F connectors with dual function. They
handle analogue line level signals and can be switched to AES3. The four XLR-M connectors
(see illustration item 10) are used to daisy chain the input signal. They carry the same signal
as fed to the XLR-F (see illustration item 5). The AES3 inputs/outputs for channels A/B are on
XLR B, for channels C/D on XLR D. The AES3 outputs are active buffered if the device is
powered and directly bypassed unpowered.
Figure6.3: TGX audio connectors
Notice!
It is mandatory to use balanced input wiring for the AES3 and/or analogue inputs. Unbalanced
cabling will not work and leads to bad audio signal.
For AES3 only cables specified for digital signals with an impedance of 110 Ohms are
recommended.
Bosch Security Systems, Inc. Installation manual 2018.05 | 01 | F.01U.330.704
In addition to the analogue and AES3 inputs, TGX amplifiers can also receive their input
signals from an OMNEO or a Dante network. The input source for each amplifier channel can
be changed via the front panel or using remote control software.

8.3 Mains operation & resulting temperature
The power drawn from the mains network is converted into output power to feed the
connected loudspeaker systems and into heat. The difference between power consumption
and dispensed power is called power dissipation (Pd). The amount of heat resulting from
power dissipation might remain inside of a rack-shelf and needs to be diverted using
appropriate measures.
For further details refer to the mains operation & resulting temperature tables available at
www.dynacord.com.
