Adjustments and Connections
1 - BALANCED
With the XLR connector it is possible to connect a balanced signal source. It uses a standard cabling scheme:
Pin 1 - ground (shield)
Pin 2 - hot connection (in-phase signal)
Pin 3 - cold connection (phase-inverted signal)
This input has a sensitivity of +4 dBu to match the sensitivity of balanced sources.
2 - UNBALANCED
The RCA connection enables connection from an unbalanced signal source. It is customary to link the 'cold'
connection (Pin 3) to ground (Pin 1). This connection is usually made at the cables. This input has a sensitivity of
-10 dBV to match the sensitivity of unbalanced sources. The unbalanced input has 12 dB greater sensitivity than
the balanced input.
3 - HPF
The HI-PASS FILTER control is to switch on or off the 12 dB/octave high pass filter. It is recommended to set it to
FR (full range: high pass filter deactivated) when the loudspeakers are used in 2.0 stereo configuration. Shape 40
has a 2-position switch: FR and 80 Hz. Shape 50, 65 and Twin have a 4-position switch: FR, 45, 60 and 90 Hz. It is
recommended to use positions 45, 60, 80 (Shape 40) or 90 Hz if a system is used with one or more subwoofer(s)
or if the listening room tends to strongly increase the lower frequencies.
4 - ON/OFF
The ON/OFF control is for switching the power supply to the internal amplifiers on and off. Moving it from the OFF
to the ON position has the effect of putting the loudspeaker on 'Standby'. To deactivate 'Standby' mode, send an
audio signal to the loudspeaker, which will detect it and move automatically from 'Standby' to 'On'.
5 – LF SHELVING
The LF SHELVING potentiometer is to activate or not a sound level correction below 250 Hz. We advise that you
adjust the LF SHELVING potentiometer to +2 or +3 dB when the acoustics of the listening room naturally attenuate
this frequency range. We advise that you adjust the LF SHELVING potentiometer to 0 when the listening room
is acoustically neutral. We advise that you adjust the LF SHELVING potentiometer to -2, -4 or -6 dB when the
loudspeakers are placed close to a wall or corner.

6- LMF EQ
The LMF EQ potentiometer is to activate or not a sound
level correction at a centre frequency of 160 Hz for a
Q factor of 1. It is advised to set the potentiometer to
-1, -2 or -3 dB when the loudspeakers are placed on a
table, console bridge or any other support that causes
reflections.
7 - HF SHELVING
The HF SHELVING potentiometer is to activate or not
a sound level correction above 4.5 kHz. We advise
that you adjust it to +2 dB when the acoustic of the
listening room naturally attenuates this frequency range
(acoustically dead environment). We advise that you
adjust it to 0 when the listening room is acoustically
neutral. We advise you to adjust it -2 or -3 dB when the
acoustics of the listening room naturally increases this
frequency range (bright environment).
