This special phono preamplifier has 2 XLR connectors: one input and one output.
The Celio is both: either a stereo RCA phono preamplifier or a mono XLR phono
preamplifier.
To upgrade from a RCA stereo to a XLR stereo phono preamplifier is sufficient to add
another Celio to the system: this preserves the investment in Your analogue hifi chain.

positioning
In the ”picture 1” we see the correct positioning of the device.
The Celio's red rappresentations indicate the no good positioning for the sound. Especially
in front of the loudspeakers.
In the rear of the loudspeakers we keep the best sound performances.

Connections - Rear Panel
In the picture 2, we see the input-output connectors on the Celio's rear panel.
This phono preamplifier can support stereo unbalanced signals and mono balanced
signals. To have a setereo balanced signals, it's necessay to have two Celio: one for left
balanced signal, one for right balanced signal.
UNBALANCED MODALITY (STEREO):
turntable's signals go in the RCA IN connectors. The output signals go out to RCA OUT
connectors.
BALANCED MODALITY (MONO):
we need of 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.
For both cases, RCA stereo signal, or XLR mono signal, the load adjusting is by the RCA
ADT connectors.
With calibrated external RCA loads linked to these connectors, we provide the correct
impedence load to the cartridge.
The device's gain is adjustable by the two commutators.
On H position the gain is high, on L position the gain is low.
The turntable's gnd cable can be linked to GND 1 or GND 2 connectors..
GND 1 is the device's body gnd. GND 2 is device's signal gnd.
We have to test in what gnd connector the noise is less.
The power supply arrives in the IEC connectors for, with their protection fuse.
