earthing of your electrical system must work properly; otherwise unwanted noise and
interference may invade the audio system.
Note that the unit when off connects
"bypass”, the input signal is directly available to the
output connecting RCA/RCA and XLR/XLR. After switching on, the blinking blue power LED
lights dimly until all internal modules are operational, (5 sec. approx.), after which it gives a
stronger light and DREI tech. starts to function, (CHECK LED in the PRO model). This is not
a fault but protects your speakers from inappropriate signals.
We
strongly recommend you to use good quality, clean, dry, rust
free interconnect cables. Periodically check the status of these connections.
Our connections are very high quality and gold
plated. We recommend periodic application of
a specific product, (ask the dealer), to the
connectors to prevent rust and loss of contact.
Balanced connections of input and output XLR
connectors are the standard in
The pin 1 = Ground
The pin 2 = Hot
The pin 3 = Cold
Inputs lines
The equipment has a pair of RCA inputs, (only in the HighEnd version) and another pair of
XLR (balanced). You can connect either one or the other. Normally, you use only one of
them.
In the case of connecting two different devices, (ex. Stereo and AV), in the two inputs
simultaneously, it is usual that the sound of the two mix at the start and do not cause
damage. In some cases there may be no sound output, usually in the unit connected to a
RCA input.
You should connect the left channel to the "LEFT" (white) and the right channel to the
"RIGHT" (red), but this is not obligatory.
It is normal for the balanced (XLR) input
signal to be louder than the RCA and this is
not a malfunction. XLR also has a higher
output volume level (+6 db.) than the RCA.
