3 Applications
The amplifier is specially designed for PA systems. It is able to supply an RMS power of 120W to 100V or 70V speakers or to a speaker group with a total impedance of 4 . Microphones (channels 1-3) or units with line level (channels 1-3 and AUX) can be connected to the input channels; these input channels can be mixed with one another. The fifth input of the amplifier is an Ethernet interface for connection to a Dante audio network. From this network, audio signals can be received via one or two Dante channels.
Input channel 1 of the amplifier is equipped with a talkover function. When an announcement is made, this function will attenuate the volume of the other channels by 40dB .
3.1 Dante
Dante, an audio network developed by the company Audinate, allows transmission of up to 512 audio channels at the same time. Dante (Digital Audio Network Through Ethernet) uses a common Ethernet standard and is based on the Internet protocol. The transmission of audio signals is uncompressed and synchronized, with

English
minimum latency. The advantage over analog audio signal transmission is a cost-effective connection of components via standard network cables and low susceptibility to interference, even in case of long transmission paths. In addition, signal routing between components that have once been connected can be changed by software at any time. In the Dante network, units configured as transmitters are used as signal sources. By means of the program "Dante Virtual Soundcard" from the company Audinate, computers can also be used as signal sources, e.g. to feed audio files replayed on the computer to the Dante network.
One or both reception channels of PA900DT are assigned to any transmitting channels in the Dante network via the Dante configuration program "Dante Controller" (Chapter 7). In the amplifier, the signals of the two received channels are mixed to one mono signal.
The Ethernet interface is also configured via the program "Dante Controller" (Chapter 7.2). For correct configuration, knowledge in network technology is indispensable.

4 Setting up the Amplifier
The amplifier is designed for installation into a rack (482mm / 19^ ) but it can also be placed on a table. Do not block the air vents; air must be able to flow through the air vents to ensure sufficient cooling of the power amplifier.
4.1 Installation into a rack
For installation into a rack, screw the two mounting brackets provided to the sides of the unit. In the rack, the amplifier requires a height of 2 RS (1 RS = rack space = 44.45 mm).
To prevent the rack from becoming top-heavy, insert the amplifier into the lower section of the rack. The mounting brackets alone are not sufficient for fixing it safely; additionally use lateral rails or a bottom plate to secure the unit.
5 Connecting the PA Amplifier
Connections should only be made by experts. Always switch off the amplifier before connecting!
5.1 Speakers
Connect either 100V speakers (fig. 1) and 70V speakers (fig. 2) or speakers/speaker groups with a total impedance of at least 4 (figs. 3-5), refer to page 2. Depending on the speaker type, use the corresponding contacts of the terminal strip SPEAKER OUTPUT (13). To make handling
easier, the terminal strip can be removed from its connector.
When connecting, observe the correct individual or total impedance of the speakers and their correct polarity (positive and negative connections as shown in figs. 1-5). The positive connection of the speakers is always specially marked.
Caution! In case of PA speakers with a 70V or 100V audio transformer (figs. 1 and 2), the total load by the speakers must not exceed 120W; otherwise, the amplifier will be overloaded and may be damaged.
5.2 Microphones
Up to three microphones can be connected to the inputs INPUT 1 to INPUT 3 (14). Instead of the XLR jack INPUT 1, the screw terminals (20) can be used alternatively.
1) When connecting a microphone, disengage the corresponding switch MIC/LINE (19).
2) For the jacks to which a phantom-powered microphone has been connected, use the corresponding DIP switch PHANTOM POWER (22) to activate the 20V phantom power (switch in lower position).
Caution! When the phantom power has been activated, make sure that no microphone or audio unit with unbalanced output signal has been connected to the input; it may be damaged.
5.3 Units with line output
Up to four units with line level output (e.g. CD player, mixer) can be connected to the inputs INPUT 1 to INPUT 3 (14) and to the input AUX IN (17). When connecting any units to the inputs INPUT 1 to INPUT 3, engage the corresponding switch MIC/LINE (19).
5.4 Inserting an equalizer or another unit
For external effects on the sound, insert, for example, an equalizer via the jacks PRE OUT and AMP IN (15).
1) Remove the jumper between the connections PRE OUT and AMP IN: The preamplifier and the power amplifier will be separated.
2) Connect the input of the unit to the jack PRE OUT.
3) Connect the output of the unit to the jack AMP IN.
Note: The amplifier will not deliver any signal if the unit inserted is not switched on, if it is defective or not correctly connected.
5.5 Additional amplifier
If the number of the speakers required is higher than the number admissible for the amplifier, an additional amplifier will be required (e.g. PA900S from MONACOR). Connect the input of the additional amplifier to the jack LINE OUT (16). The output level at the jack is independent of the control MASTER VOLUME (5).
5.6 Power supply and emergency power supply
For continued operation of the amplifier in case of mains failure, connect a 24V emergency power supply unit (e.g. PA-24ESP from MONACOR) to the terminal strip DC INPUT (12). To make handling easier, the terminal strip can be removed from its connector. Finally connect the mains cable provided to the mains jack (9) and then to a mains socket (230V / 50Hz)
Notes:
- When a 24V voltage from the emergency power supply unit is applied to the terminals DC INPUT, it will not be possible to switch off the amplifier with the POWER switch (8). In case of mains failure or when the POWER switch is set to "Off", the amplifier will automatically switch to emergency power supply.
- During emergency power supply, the amplifier will deliver less power than during mains supply.
6 Operation
1) Prior to switching on the amplifier for the first time, first set the controls INPUT 1 to 3 (1) and the controls NETWORK (2), AUX (3) and MASTER VOLUME (5) to the position "0".
2) Use the POWER switch (8) to switch on the amplifier: The LED ON (6) will light up.
3) Turn up the control MASTER VOLUME (5) so that the subsequent settings will be audible.
4) Set the volume controls INPUT 1 to 3 (1), NETWORK (2) and AUX (3) to the desired value.
5) Use the tone controls BASS and TREBLE (4) to adjust an optimum sound.
6) Use the control MASTER VOLUME (5) to adjust the total volume. A row of five LED indicators (7) will indicate the output level.
Caution: Never set the audio system to a very high volume. Permanent high volumes may damage your hearing!
6.1 Talkover function of channel 1
Via channel INPUT 1, announcements can be made during a music program. For this purpose, the volume of the other channels will be automatically attenuated by 40 dB. To activate this function, engage the button AUTOTALK (21).
7 Configuration of the Dante Network
PA-900DT is configured as a receiver in the Dante network by means of the program "Dante Controller", available as a free download on the website of the company Audinate. The settings made via the program will be saved in the corresponding transmitters and receivers of the Dante network so that the program is only required for network configuration but not for normal operation.
