no circuit elements between the audio processor and the internal stereo encoder that can cause waveform
distortion. We therefore recommend using the Mirage with its built-in stereo encoder whenever it becomes
feasible.
1.6
Positioning
The best position of the processor is as good as possible to the transmitter, so that the stereo encoder
output can be connected to the transmitter over a short path, causing minimal variation in MPX signal
waveform.
The processor outputs can drive a coder with a cable length of up to 3 m without any appreciable
degradation of the MPX signal.
If this position is not possible, the best solution is to use digital audio signal transmission.
To ensure maximum transmission quality, all downstream equipment of the study must be carefully
aligned and meet the appropriate standards for wavelength, distortion, traction wave lags and
stability.
These devices must be re-checked at reasonable intervals.
It is therefore important that the audio source connected to the processor has low output noise, flat
frequency response and low distortion
The buffered outputs of Mirage Dig Evo can drive a coder with a cable length of up to 10 m. Before
any appreciable degradation of the MPX signal occurs.
1.7
First turn On
Before turning on the Mirage Dig Evo, make sure that the mains voltage is in accordance with the
voltage range indicated on the rear of the power supply and that the electrical system to which the
Processor is connected has a good grounding.
