4.9 BASIC CONNECTIONS
In order to correctly interface CLIO with the outside world you should always keep
in mind the following electrical specifications:
MAXIMUM INPUT VOLTAGE: +40 dBV (283 V peak-to-peak)
MAXIMUM OUTPUT VOLTAGE: +18dBu (6.156Vrms) (sine)
INPUT IMPEDANCE: 128 kOhm
OUTPUT IMPEDANCE: 660 Ohm
4.9.1 CONNECTING THE CLIO BOX
The CLIO system is stereo and can simultaneously process two balanced analog I/O
channels which are named channel A and B. The output of channel B is usually
driven in parallel with channel A output.
The CLIO Box input uses two XLR Combo female connectors. These particular
connectors accept also a 6.3mm standard jack.
The CLIO Box output uses two XLR male connectors. In parallel you also find two
RCA plugs that are used to take the output signal unbalanced.
Please note that there it will always be a 6 dB difference between the CLIO
balanced and unbalanced outputs.
By default the Output Level display is referred to the balanced output, in this
case the unbalanced output level is 6 dB lower. In order to display the
unbalanced output level is necessary to select the option in the Output Level
display; in this case the balanced output is 6dB higher than the unbalanced one.
Figure 4.26
On the rear panel you also find a digital SPDIF output.
Unless you are carrying out impedance measurements with the Internal Mode
selected, one of CLIO outputs will usually be connected to an external power
amplifier that will drive the loudspeaker or to the electronic apparatus or other
system under test.
The output of the system under test will be connected to one of the CLIO inputs.
