CLIOwin 6.5 PCI User's Manual - Audiomatica Srl

This DC voltage ranges from -2.5V to +2.5V (at SC-01 channel A output) as you may
set with the slider.
Note: if you feed channel A output to a DC coupled amplifier (like the CLIOQC
Amplifier&SwitchBox) the DC voltage that you will see at the amplifier's output will be
multiplied by its gain. This is why the control panel also displays the calculated DC voltage
present at the QCBox output; the calculation takes into account the QCBox type
selected in the External Hardware control (see 5.5.1). For example the DC voltage that
may be present at the output of the QCBox Model 4 ranges from -25V to +25V.
With the Set DC
button it is possible to activate the desired DC. When DC is active
the control panel button becomes red to signal this particular state as in figure below.
The small Zero DC button lets you immediately reset the output DC to 0V.
Pay great attention when driving loudspeakers with signals with DC present.
5.4.4 INPUT CONTROL
input sensitivity display & control buttons
Displays the actual input sensitivity (in dBV) of the instrument, i.e. the voltage level
beyond which the board saturates. It is possible to modify it in 10dB steps pressing
the (or F9) and (or F10) buttons.
Selects the Autorange mode. When in autorange the input sensitivity is automatically
adjusted by the instrument to achieve the optimum signal to noise ratio.
5.4.5 MICROPHONE CONTROL
Switches the phantom power on and off. This 8.2V supply is needed to operate
Audiomatica's microphones MIC-01 and MIC-02.
Enters the Microphone Sensitivity dialog box.
