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 kΩ 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.
