IMPORTANT: The DX8000-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 DX8000’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 DX8000.
