The DALI PHANTOM CI AMP-2500 DSP is an amplifier unit designed for audio signal amplification and connection to moving-coil loudspeaker systems. It features network configuration, control, GPIO, S/PDIF audio I/O, balanced and unbalanced audio inputs, speaker outputs, mains power input, and WiFi antenna. The amplifier has a Class-I product classification and should be installed with a mains cable that includes the required earth connection for safety compliance. It should be installed by competent and qualified personnel to avoid any damage or failure that may invalidate support, warranty, or guarantees of performance. The amplifier is not suitable for use in locations accessible to minors. It is intended for amplification of audio signals within the frequency range of 20Hz to 20kHz and for driving moving-coil loudspeakers.

Product Usage Instructions

1. Open the carton and check the contents. The package should include the following items:
   • 1 x Amplifier unit
   • 2 x Two channel balanced input connector
   • 1 x Two channel output connector
   • 1 x GPIO socket connector
   • 1 x Mains power cable
   • 4 x Adhesive rubber feet
2. Ensure proper ventilation space around the amplifier. The grey regions in the illustration indicate the ventilation space requirements.
3. If you want to rack mount the amplifier, attach it to the rack uprights using standard rack-mount M6 bolts and nuts.
4. If you prefer free-standing installation, attach the supplied adhesive feet to the underside of the amplifier.
5. Make sure to connect all input and output connections before switching on the amplifier.
6. For input connections, use the provided balanced or unbalanced audio inputs according to your setup. Channel 2 is for the right audio channel, and Channel 1 is for the left or LFE (Low-Frequency Effects) channel.
7. For output connections, use the speaker outputs. Channel 1 is for the left speaker, and Channel 2 is for the right speaker.
8. If you want to connect a subwoofer, use the Subwoofer (LFE .1) connection. The amplifier supports up to 4 subwoofers.
9. The default input and output format is shown in the diagram. However, you can configure alternative formats using the PHANTOM AMP CONFIGURATOR web page interface. Refer to the installation manual for instructions on configuring input and output formats.

For detailed technical and safety notices, please refer to the user manual provided with the product.

TECHNICAL AND SAFETY NOTICES

Please read the following important technical, safety and environmental notices before installing and using your amplifier.

Technical Notices
All reasonable design and engineering steps have been taken to ensure that this amplifier always performs satisfactorily in its intended application and environment and will provide appropriate levels of support to ensure that all reasonable customer needs and expectations are met. Such support however is contingent on the following provisions.

1. This amplifier is a Class-I product and should be installed with a mains cable including the required earth connection to comply with the Safety Class-I.

2. This amplifier should always be installed by competent and qualified personnel. Amplifier damage or failure caused by installation or operational errors may invalidate support, warranty or guarantees of performance.

3. This amplifier is not suitable for use in locations where it may be accessible to minors.

4. This amplifier is intended to be used specifically for the amplification of audio signals and for connection to moving-coil loudspeaker systems. Use of this amplifier for amplification
   of signals outside the audio band (20Hz to 20kHz) or to drive transducers other than moving-coil loudspeakers may invalidate support, warranty or guarantees of performance.

5. This amplifier should only be used within professionally installed and configured audio systems comprising input and output ancillary equipments that is known to be of an appropriate level of performance and in good operating condition. Any damage to, or unsatisfactory performance from, this amplifier caused by inadequate or failed input or output ancillaries may invalidate support, warranty or guarantees of performance.

6. This amplifier is intended to be installed and operated indoors in a controlled environment (pollution degree PD2) within an ambient temperature range of 0°C to 40°C. This amplifier is not intended for use above 2000 meters above sea level. Amplifiers installed or operated in environments outside these limits may invalidate support, warranty or guarantees of performance.

7. Specific warranty terms are the responsibility of the amplifier re-seller.

Safety and Environmental Notices

• Note: The intent of the lightning flash with arrowhead symbol in a triangle is to alert the user to the presence of uninsulated “dangerous” voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans.
• Note : The intent of the exclamation point within an equilateral triangle is to alert the user to the presence of important safety, and operating and maintenance instructions in this manual.
• WARNING! TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.
• Ambient Temperature Note : If this equipment is operated in a confined or multiple rack installation, the internal ambient operating temperature may exceed the external ambient temperature. It is important to ensure in these circumstance that the published maximum operating temperature for the equipment is not exceeded.
• Reduced Air Flow: Ensure that rack or other closed installation does not restrict the cooling airflow required for safe and reliable operation of the equipment.
• Class 2 Wiring: Exposed high voltage on the speaker terminals. Touching the uninsulated terminals or wiring may result in an unpleasant sensation.
