Amplifier Control Unit

CobraNet compatible 16-channel D/A converter and monitor/control unit.

• The ACU16-C converts up to 16 channels of digital audio (48 kHz, 20-bit or 24-bit) to analog using CobraNet technology, and delivers 

analog audio to Tn series and PC-1N series power amplifiers with a dynamic range of 110dB.

• A single ACU16-C unit can control up to 32 amplifiers.

• Amplifier settings and status can be monitored and controlled using the supplied NetworkAmp Manager software and a computer: 

power on/standby, attenuation, out/in levels, temperature, load impedance, and more.

• A computer can be connected to any NHB32-C or ACU16-C in the network to provide full monitoring and control capability for all 

amplifiers on the CobraNet network.

• Automatic troubleshooting and logging.

• Redundant connections for exceptional reliability.
