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.
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.
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.
