The DX8000 supports audio recording capabilities with the installation of the DX8000-AUD audio expansion option. Audio inputs correspond to 
video inputs; therefore, an eight-channel DX8000 Series DVR can accept eight audio inputs and a sixteen-channel DVR can accept sixteen audio 
inputs. Audio and video inputs are configured in a one-to-one relationship. For example, audio input seven corresponds to video channel seven.

The DX8000 accepts up to 16 individual monaural audio inputs. Each input is designed to receive a line-level, analog audio signal that is sampled 
at a rate of 48 kHz (16 bits) by the DX8000-AUD’s digital analog converters (DAC). To minimize the amount of storage required to store audio data, 
the audio stream is down-sampled to 8 kHz (8 bits) for storage and playback.

Audio input to the DX8000 is provided through an audio cable consisting of eight RCA connectors wired to a 15-pin D-sub breakout connector. 
The D-sub connector plugs into the rear panel of the DVR. Depending on your system’s configuration, either one or two breakout cables will be 
required to connect the DVR to an audio system.

1. Connect the 15-pin D-sub audio breakout connector to the rear of the DVR to provide eight individual audio inputs. Refer to Figure 82.
