Network amplifiers are audio devices that combine amplification with IP connectivity, allowing audio to be received and managed over a network rather than solely through analog connections. They typically include basic mixing and control features, making it easy to manage multiple audio sources from a single device.

They are mainly used in public address and distributed audio systems, such as in offices, shopping centers, or schools. Thanks to the network, they allow you to centralize audio control, send announcements or music to different zones, and easily expand the system.

Audio

Nominal power1.000 W
Frequency response100 V COM / 70 V COM: 50 ~ 20.000 Hz (±3 dB)
RCA Out / 3,5 mm out: 50 ~ 20.000 Hz (±1 dB)
Total harmonic distortion (THD)<0,5 % a 1 kHz, 1/3 de la potencia nominal

Interfaces

Alarm (Euroblock)1x EVAC alarm
1x Alarm input
1x Alarm output

If the output device connected to the alarm output is a "normally closed" type, connect: 1A to GND; if it is a "normally open" type, connect: 1B to GND.
Ethernet (RJ45)1x LAN (10 / 100 / 1000 M)
Local storage4 GB (EMMC)

The space available for audio files is 1 GB.
AudioTICKETS:
4x MIC (6,35 mm Jack) -28 dBV, 4,7 kΩ, unbalanced output (cannot be connected without a microphone)
4x RCA (Pin Jack) 0 dBV, 4,7 kΩ, non-balanced output
1x USB 2.0
Bluetooth 5.0 (range: 10 m)

EXITS:
4x Constant voltage output 100 V COM and 70 V COM
A single channel supports an output power of up to 250 W
2x RCA (pin jack) 0 dBV, unbalanced output
2x Output (3,5 mm jack) 0 dBV, unbalanced output

If the constant-voltage mode is set to 100 V, the output interface must be connected to a speaker with a rated voltage of 100 V. Connecting to a speaker with a rated voltage of 70 V could damage the device.
Led indicator1x Power supply: A steady white light indicates that the device is working properly.
1x USB: A steady white light indicates that the device is in USB mode.
1x Bluetooth: Solid blue light: the device is in Bluetooth mode.
1x EVAC: Solid red light; the EVAC alarm has been triggered.
1x MIC 1: The MIC input 1 is connected correctly.
1x Module: A steady FLT light indicates an overload or other system malfunctions.
1x CLIP: Steady light indicates clipping or other exceptions.
1x SIG: Solid light indicates normal operation.
Volume1x Total (potentiometer)
4x MIC input (potentiometer)
4x RCA input (potentiometer)
4x Output channel (potentiometer)
1x Treble (potentiometer)
1x Bass (knob)
