SETTING UP AUDIO OUTPUT
The DX8100 delivers a line-level monaural signal through a standard 0.125-inch phone jack on the rear panel of the DVR. It is recommended that
the audio output of the DX8100 be connected to an amplifier in order to boost the output signal to a level that is sufficient to drive a speaker.
Figure 94 illustrates an example of an audio output configuration.
Some speaker systems integrate both amplifiers and speakers in a single unit. Such a system can be connected directly to the audio output of the
DX8100 without the need for external amplification.
To setup the audio output:
1. Connect the audio output of the DX8100 to an audio amplifier.
Use an audio cable with a 0.125-inch miniature male phone plug on one end to connect to the audio output of the DX8100. Ensure that the
opposite end of the cable has the appropriate connectors for connection to your amplifier.
2. Connect the audio amplifier to a speaker.
