1.7 Connecting Inputs
. Input connections are made via the 3-pin XLR-male type on the rear side of the amplifier. The
connection for "LQ" model
is shown in figure 1.7.1; on the right side of the figure is shown the polarity of
the XLR connector.
(four channels)
figure 1.7.1
The figure below shows the connection of analog input for balanced and unbalanced line. You can use both configuration,
but you must consider that unbalanced long line can introduce noise in the audio system. The Link switch located in the
rear panel is for direct paralleling the rear input connectors. You can use the remaining input connector to carry signal to
other amps.

In the "LD" model (two channels) the input connections are in the right side of the panel; the remaining input connections
are connected in parallel with the first ones with the default settings and you can use it as input connections with other
amplifiers; in the models with DSP built-in (optional), these connectors function as outputs of sub channel of DSP board
(see figure 1.7.3).
