Available options

• Standard Signal Inputs Module: The HPX Series amps are equipped as standard with a Neutrik® XLR input doubled by other XLR connectors for linking purpose, per channel

DSP HPXThe HPX Series Digital Signal Processor is real time fully programmable through Ethernet, USB or directly from the front panel. There are two different versions: 4 Inputs/4 Outputs or 2 Inputs/2 Outputs totally free route configurable. Both versions include post-processor signal XLR output connectors to link the processed signal to another amplifier without DSP.

• Dante Domain Manager™ (DDM) Networking Audio Input: 4 inputs channels of Dante™ can be installed in the HPX Series equipped with DSP. Sampling frequency can be configured as 48, 96 or 192 kHz. Audio format is Dante Audio over IP and AES67 RTP. Two RJ45 connectors are configurable as 1 GHz/100 MHz for Primary/Secondary network, or standard switch.

• AES3 Input: Provides standard AES3 (AES/EBU) digital input using two input XLR connector in 4 channels models or one XLR connector in 2 channels models. It include a high performances sample rate converter to adapt any signal. You can select Digital/Analog input using the front panel Menu, where you can configure also the termination resistor.

• Ethernet LAN Port: standard RJ45 connector for Ethernet network connection. Using it you can control/monitor the amplifier and the DSP.

• GPIO module for HPX Series: This General Purpose Input Output (GPIO) module, permits monitoring the amplifier ON/OFF status (GENERAL PURPOSE OUTPUT) to control an external device by an internal relay.

GENERAL PURPOSE OUT connector provides some contacts to monitoring the status. Contacts marked as OK will remain short-circuited when amp is correctly working and will be opened if the amplifier is in standby mode.
