5.2 SPEAKON ® Loudspeaker Output Connectors
The four SPEAKON ® connectors are connected to the channel A to D power
amplifier outputs. The pin configuration of the connectors is:
SPEAKON ® output 2
(View from the back)
SPEAKON ® output 1
(View from the back)
Pin 1 + Channel C Pin 1 + Channel A
Pin 1 – Channel C Output – Pin 1 – Channel A Output –
Pin 2 + Channel D Pin 2 + Channel B
Pin 2 – Channel D Output – Pin 2 – Channel B Output –
SPEAKON ® output 4
(View from the back)
SPEAKON ® output 3
(View from the back)
Pin 1 + Channel D Pin 1 + Channel B
Pin 1 – Channel D Output – Pin 1 – Channel B Output –
Pin 2 + Channel C Pin 2 + Channel A
Pin 2 – Channel C Output – Pin 2 – Channel A Output –

NOTE / IMPORTANT
The
Q-POWER 14
uses a bridged power amplifier output stage. This implies
that the “Output –” loudspeaker outputs are not (and must never be)
directly connected to the electrical ground (earth) or chassis of the amplifier!
Please make sure to always attach the loudspeakers between the
“” and the “Output –” outputs of the same channel.
! WARNING!
SPEAKON ® connectors marked with the lightning flash indicate high vol-
tages that are potentially life threatening.
Wiring to these terminals requires installation by an instructed person or the use
of ready-made leads or cords. Custom wiring must only be made by qualified
personnel.
To prevent electric shock, do not operate the amplifier with damaged loud-
speaker cables (i.e. if the isolations are damaged or if the internal wires are
exposed).
Wiring to the output connectors must conform to NEC Class 2 safety standards
or its equivalent that meets all national and local electric codes.
l NOTE
For reasons of safety and performance, use only high-quality fully in su-
lated speaker cables of stranded copper wire.
Use the largest wire size that is economically and physically practical, and make
sure the cables are no longer than necessary.
The Q-POWER 14 amplifiers can handle any loudspeaker impedance down to
2 Ω.
Lower impedances are still safe, but will result in less efficiency, increased heat-
ing of the amplifier stages and possibly noticeable loss in audio quality. Imped-
ances lower than approximately 0,6 Ω (ideal resistive load) can lead to short term
shutdown of the corresponding amplifier module. Once the underimpedance
situation is gone, the amplifier module will resume normal operation.
