Available signal inputs and outputs
(*) NOTE:
This amplifier follows the ground interconnection specification defined by
AES48-2005 standard of the Audio Engineering Society, on grounding and EMC
practices for audio equipment containing active circuitry. For that reason, when a
source with unbalanced outputs should be connected,
it is recommended not to
use Pin1 of the XLR, and never connect it to Pin3
. If a shielded cable is available,
the shield may be connected to Pin1 of the XLR to get some shielding, leaving the
other end unconnected. Pin1 connection is only advised if the equipment with the
unbalanced output has a dedicated connection for the shield, separate from the
audio signal ground reference.
Before powering up the unit, make sure that the input and output XLR cables are in
good state and following the above described pinning diagram, as defined by the
AES14 standard.
When connecting the XLR, please mute the outputs with the front panel switches
until you configure the signal processing. Loudspeakers may be damaged due to a
wrong setup. It is advisable unmute first the L and R channels: in case they are
connected to a subwoofer driver channel by mistake, it cannot be damaged.
Otherwise, high frequency speakers may be damaged because of trying to
reproduce low frequencies. When the L and R channels are properly connected,
proceed to unmute the subwoofer channel.
5 OPERATING THE AMPLIFIER
5.1 Start-up and operation
Once the mains, loudspeaker and sound sources (input) connections have been
made correctly, start up the pre-amp sources and then press the ON/OFF switch on
the rear panel. The amplifier is equipped with a Soft Start circuit, which assures a
gentle, pop free start up, avoiding stress to the loudspeakers.
