LOCATION
Place the unit on a solid shelf away from vibration and heat sources. Do not
expose to direct sunlight making it difficult to read the display. Do not
place it near sources emitting light that might disturb the good reception of
remote control commands.
In the case of an asymmetric binding of the preamplifier, make sure it does
not exceed one meter between the reader or between the amplifier, to avoid
background noise. This distance is more important in the case of a balanced
connection.

OUTPUT CONNECTIONS
Do not short-circuit the output of the unit, never connect the left and right
outputs together, it can damage the circuitry of the output stage in Class A.
On the rear of the preamplifier, you have three outputs (OUTPUT): two
symmetrical format, taken on two pairs, XLR 1 and XLR 2, and a format of
an asymmetric pair of RCA jacks.
Using a pair of cables terminated with XLR connectors for balanced
transmission or by praying for RCA unbalanced use, connect the left and
right channel outputs of a Strumento No. 1 respectively to left and right
channels of the input of a stereo amplifier.
The same pair of wires may connect the two channels of this output to the
input of each of the two mono blocks dedicated to each of the two channels.
Several outputs can be used simultaneously.
The use of interconnect cables of the highest quality is strongly
recommended.
The polarity of the pin XLR connectors output is shown on the diagram
below:
Keypad of the outputs of each channel has still an output "REC" on RCA, it
is a fixed output level, the signal of the selected input, for connection to a
recording device.

INPUT CONNECTIONS
Before connecting, make sure your device and other devices in your system
are turned off.
Audia Strumento No. 1 preamplifier has 5 stereo inputs, high-level and
variable gain:
• 2 inputs (INPUT 1 and INPUT 2) whose format is selectable balanced or
unbalanced for each by the «SET » (see below) to enable the XLR balanced
if the connection is chosen or activate RCA if it is the unbalanced
connection is chosen.
• 3 other inputs (INPUT 3, INPUT 4 and INPUT 5) in symmetrical single
format on XLR.
Using cables terminated with the proper jacks, connect the left and right
channels for each source respectively to left and right of the entrance to the
Strumento No. 1 preamplifier dedicated to this source.
Cable modulation of the highest quality are recommended for these
connections.
The polarity of the pin XLR input is shown on the diagram below:

COMMUNICATION LINK
If you have multiple Audia Flight units equipped with outlets suitable, you
can link them together and synchronize their firing and transmitting data or
service. This requires connect one end digital RJ45 cable provided in one of
the two jacks to the back of the unit and similarly, the other end in a socket
at the rear of Audia Flight unit the other. Perform these connections, all
devices off.
Never use the cable for another use or for a device that would not be an
Audia Flight.
In case of a connection between Strumento No. 1 and Audia Flight cd
players (CD ONE CD TWO or THREE CD) or power amplifier like
Strumento No. 4, it is best to place the switch located next to the catch the
latter position "slave" and select the preamplifier as "master" in the menu of
its function «SET ».
