CONTROLS AND FUNCTIONS
118 FSA
ON: Indicates that the system is «ON».
DELAY: Control of a digital delay line acting on the input signal; in this way it is possible to make up for the vertical misalignment of sub and
satellite. The delay is expressed in meters and goes from 0.5 to 3.5 mt. with 50cm steps.
LEVEL: It adjusts the signal general level.
PRESET: Selects 8 presets, each of whom corresponds to a specific speaker configuration according to users’ personal preferences and to
the acoustics of the listening area (see PRESET section).
GND LIFT: Switch to isolate the chassis ground and the signal ground to avoid ground loops, which can cause hum problems.
PHASE: The phase control allows to optimize phase alignment, i.e. to obtain a uniform frequency response in the crossover area between
the sub and the satellite. When it is set at 0°, the sound emission is in phase with the input signal; when it is set at 180° the sound emission is
in counterphase with the input signal; thanks to this control, subwoofer adjustment will be even more flexible with a consequent performance
optimization.
PEAK: When this led lights up, it indicates that the signal is reaching saturation.
LMT/PRT: If this led lights up there is a system malfunction due to an internal amplifier failure or to the intervention of current limiting circuits
against thermal overload.
IN-LINK: Balanced input / output sockets: «IN» allows to connect a pre-amplified signal such as that coming, for instance, from mixer output.
«LINK» allows to connect multiple speakers to the same signal.
