XSerie Parallel Multi Preamp
< 8 >
►Input lines
The preamp has non-balanced inputs 1 - 2 - 3 - 4 in line or low level, where you can
connect any audio source like CD players, radios, etc.
You must connect the left channel to the "LEFT" (white) and the right channel to the
"RIGHT" (red).
Input 1 is dual, it can be connected balanced (XLR) or
unbalanced (RCA), but only one of the two works
depending on the position of the switch located in the
centre next to these sockets. Follow the direction of the
arrows, up for RCA, down for XLR.
It is normal for the balanced input signal to be
different than the RCA and this is not a malfunction.
All the inputs are equal but we recommend that the
source you use most frequently be connected to number
2, as by default it is the active input when you turn on the
preamp.
►Output to Amplifier
You should connect the output marked "OUT" directly to the associated amplifier and can
use either unbalanced (RCA) or balanced (XLR) connections as both are always active.
For the advanced dynamics features of the DREi tech system you should not insert any
device between the preamplifier and amplifier. Direct coupling of the output with 12
transistors is used and there is no decoupling capacitors.
Note that when you connect your device there will not be an output signal for a few
seconds until all the internal modules are operational after which the blue power light will
come on. This is not a failure; it protects your speakers from inappropriate signals. The
same happens when you turn off the HC "active" mode.
Please read the following paragraph.
►Switching the HC to “invisible”mode.
All models and versions have "HC", Home Cinema, and invisible sockets as explained
below.
Here you can connect the low level left and right front output channels of your receiver
for AV (audio / video) or home theater.
With the preamp on, this socket has no use, so that does not affect your stereo signal in
any way but when you want to watch a movie or listen to your AV receiver, simply turn off
the preamp, after which it goes into "invisible” mode, the HC input is automatically
connected to the output "OUT" unbalanced (RCA) of the preamplifier, so you can enjoy your
soundtracks through the main amplifier and its main front boxes. Bear in mind that the
balanced output (XLR) will have no signal, (only in HC active mode).
CAUTION. Do not connect this socket to anything that does not have its own volume
control, as this may damage your speakers and your ears. Note that maximum volume
would go to the amplifier.
CAUTION. Never turn off the preamp if you have connected this input to an AV receiver
without first being sure that the output volume of the AV receiver is low or turned off. It may
damage your speakers and your ears.
