ARCHON
50
110 / 112 / 115 CONNECTIONS
The ARCHON series 110 / 112 / 115 models can be setup in FULL-RANGE or BI-
AMP mode.
For work mode selection refer to page 51.
The FULL-RANGE mode allows connection through Speakon connectors (1+ / 1-)
or terminal board with constant impedance (8Ohm) and 100V voltage.
BI-AMP mode only allows to use Speakon connectors (1+ / 1- LF) (2+ / 2- HF)
CONSTANT VOLTAGE LINE
Connect a conductor from the speaker terminal marked with “COM” to the 100V
line in the amplifier terminal marked with “-“, “0”, “COM”.
Connect the other conductor, choosing between “HI” and “LO” depending on the
desired power, to the 100V line in the amplifier terminal marked with “100V”, “+”.
CONSTANT IMPEDANCE CONNECTION
NOTALLOWED on 100V lines.
Connect a conductor from the speaker terminal marked with “COM” to the amplifier
terminal marked with “-”.
Connect a conductor from the speaker terminal marked with “8 Ohm” to the
amplifier terminal marked with “+”.

Speakon connectors are connected in parallel mode. One connector can be used
to connect the box to the output of a power amplifier, the other to connect to a
second box.
Loudspeaker cables shall have the adequate diameter, depending on the overall
lenght of the connection. The resistance introduced by an inadequate wiring
towards the loudspeakers would reduce both the power output and the damping
factor of the loudspeaker.
