REAR PANEL
Power amp output connection for SYSTEM, SUB and
TOP channels is provided via professional SPEAKON-
type output connectors. This mechanically and
electrically safe connection method complies with any
safety standard allowing the use of high-performance
loudspeaker cables with diameters of up to 4 x 2.5mm
2
.
The DYNACORD accessory program offers single
connectors and couplings as well as high-performance
loudspeaker cables.
The four poles of the system connector are assigned
as follows: the low-frequency signal is present via
pins 1+ and 1- while pins 2+ and 2- carry the Mid/
Hi-range audio signal. Using four-pole SPEAKON
speaker cables allows quick, trouble-free and correct
connection of loudspeaker cabinets that provide
system connectors – like FX 12 and FX 20.
A plastic lid covers SUB and TOP connectors to
prevent inadvertent erroneous connection. Remove
these covers only in the event that you are going to
connect speaker systems that do not provide system
connectors. Keep in mind that the bass and mid/hi
audio signals are present on the SUB and TOP
connectors’ pins 1+ and 1-.
POWER AMPLIFIER OUTPUT CONNECTORS
Caution:
The FLASH symbol “ ” at the loudspeaker connectors indicates that high voltages are present at
these connectors which, when getting in contact, can cause harm to someone’s health.
The ground-lift switch allows eliminating noise loops. When operating
the power amplier in a 19” rack-shelf system or cabinet together
with other equipment, setting the switch to its GROUNDED position is
recommended. When operating the power amplier together with
appliances with differing ground potentials, set the switch to its
UNGROUNDED position.
Under normal circumstances, the mains fuse only blows in case of
fault. Replacing the fuse is only permissible for authorized service
personnel using a new fuse of the same type with identical amperage,
voltage and blow characteristics. The high-performance mains cord
supplied with your power amplier complies with applicable
safety regulations, plus that its diameter corresponds to the power
amp’s power output capacity. Whenever possible make sure to use the
supplied mains cord for connecting the power amp to the mains
network. Using a different mains cord with a smaller diameter results
in higher leakage, consequently reducing the amplier’s maximum
power output capacity.
