Connections - Rear Panel
In the picture 2, we see the input-output connectors on the Celio's rear panel.
his phono preamplifier can support stereo unbalanced signals and mono balanced
signals. o have a stereo balanced signals, it's necessay to have two Celio: one for left
balanced signal, one for right balanced signal.
UNBALANCED MODALI Y (S EREO):
turntable's signals go in the RCA IN connectors. he output signals go out to RCA OUT
connectors.
BALANCED MODALI Y (MONO):
we need two Celio.
For one channel, we take one Celio and the signal goes in the XLR IN connector and the
output signal goes out to XLR OUT connector.
For the other channel, we take the other Celio and the link is identical to the first Celio.
he device's gain is adjustable by the two commutators.
On H position the gain is high, on L position the gain is low.
he turntable's GND cable can be linked to GND 1 or GND 2 connectors..
GND 1 is the body GND. GND 2 is the signal GND.
We have to test in what gnd connector the noise is less.
he power supply arrives in the IEC connectors for, with their protection fuse.
he optimal load cartridge is set by 5 microswitches, for each channell.
he correspondence positions-resistive value is printed on Celio rear pannell.
It is visible at the picture 2.
he red button is for turn on/off the device. Grandinote advises to keep the Celio always
ON. Only for the long inactivity time, we advise to turn off the pre-amp.
