Audio Applications
When installed, the HPA-DAC8 converts the HPA Series amplifier into a digital audio
network amplifier and makes the HPA Series amplifier the “go to” solution for a variety of
applications including:
• Restaurants
• Government Facilities
• Schools
• Industrial Facilities
• Houses of Worship
Matching Gain from a Source to the HPA Series Amplifier in a
Dante
®
Network
Understanding the gain structure is very important to avoid clipping the audio signal or
amplifier output. There are three potential ways to clip the signal chain.
1. Amplifier Input Clipping - This occurs when the applied input signal exceeds the
maximum input level of the amplifier input stage.
2. Amplifier Output Clipping - When the channel level controls are set to maximum,
0dBV / 1V of input signal is required to achieve maximum amplifier output.
Note:
AtlasIED recommends the level to be set with the level being controlled from
the source. Exceeding 1V or 0dBV level will cause the amplifier output stage to clip.
3. Digital Clipping - This occurs when the 0dBFS levels are exceeded. This is very
important to understand. Several examples are provided to help understand digital to
analog gain structure.
Note:
AtlasIED recommends to always place a limiter set for 0dB
in the signal path prior to the Network Output of the transmitting device. This is the
best way to prevent clipping the HPA-DAC8.
