Inserting/removing the grilles
The ALPHA EVO loudspeakers are supplied with one grille for the tweeter and one grille for the woofer. To remove a grille,
simply use your fingers to pull on the notches above and below the grille, taking care not to damage the tweeter or woofer.
If necessary, use a plastic object to gently pry it off. To insert the grille, line up the grille notches with the dedicated slots and
press gently (fig. I).

ALPHA 50 EVO, ALPHA 65 EVO, ALPHA 80 EVO and ALPHA TWIN EVO settings and connections
1 – BALANCED - XLR
The XLR socket allows you to connect a symmetrical signal source and uses a standard cabling diagram:
Pin1 = earth (shield) Pin 2 = hot point (in-phase signal) Pin 3 = cold point (out-of-phase signal)
The sensitivity of this input is +4dBu, corresponding to the sensitivity of symmetrical sources.
2 – BALANCED - TRS
The TRS socket allows you to connect a symmetrical signal source and uses a standard cabling diagram:
Tip: hot point; Ring: cold point; Sleeve: earth
The sensitivity of this input is +4dBu, corresponding to the sensitivity of symmetrical sources.
3 – UNBALANCED
The RCA socket allows you to connect an asymmetrical signal source. The "cold point" (Pin 3) is usually connected to the earth
(Pin 1). This connection is usually made with cables. The sensitivity of this input is -10dBV corresponding to the sensitivity of
asymmetrical sources.
4 - SENSITIVITY
Use this function to enjoy a higher volume, if necessary. The sensitivities available are 0 and +6dB. The +6dB position offers
the benefit of being able to increase the monitor volume while avoiding any saturation of the output stage of the converter
or the sound card.
5 - ON/OFF
Use the ON/OFF switch to turn the internal amplifiers on or off. Switching from the OFF mode to the ON mode has the effect
of putting the loudspeaker into "Stand-by" position. To disable the "Stand-by" mode, send an audio signal to the loudspeaker,
which will detect it and automatically switch from "Stand-by" mode to "On" mode.
6 - LF SHELVING
Use the LF SHELVING knob to activate or deactivate a correction of the sound volume below 300Hz. It is advisable to adjust
the LF SHELVING knob to +2dB if the listening location's acoustics naturally dampen this frequency range. It is advisable to
adjust the LF SHELVING knob to 0 if the listening location is acoustically natural. It is advisable to adjust the LF SHELVING
knob to -2, -4 or -6dB if the loudspeakers are positioned close to a wall or a corner.
