2. Connect each of the 8 or 16 RCA-type audio connectors to a line-level (+4 dB) gain audio source. Refer to Figure 92.
The DX8108-AUD/DX8116-AUD option accepts an unbalanced, line-level audio signal only. Line-level signaling requires a voltage between
-1 V and +1 V into an impedance of 1 k
Ω or more. This means that the output of most microphones will be too low to function when
connected directly to the DX8100’s audio inputs. In most applications, a preamplifier such as the Louroe Electronics ASK-4 ® KIT #101 will
be required to boost the signal of a microphone to a level that is acceptable for input into the DX8100.
3. Refer to the DX8100 Operation and Programming manual for information about configuring optional audio recording features.
