Manual Alea-4 - 2018-07 EN
Setup
The Alea-4 loudspeaker is designed for standing, vertical and horizontal operation. A variety of accessories is
available from Voice-Acoustic to securely attach the loudspeaker safely on tripods, distance rods or hanging
it from on trusses, ceilings and walls. Ensure that the loudspeakers are securely attached to prevent personal
injury and damage of property.
Connecting cables
When connecting the cables to the loudspeaker, ensure that the polarity (+/-) and pin assignment (1/2) is
correct. Incorrect connection results in a significant change in the loudspeaker sound characteristics and may
damage the compression driver.
The two connection sockets on the back of the loudspeaker can be used to link multiple loudspeakers on a
single amplifier. Note that parallel connection reduces the total impedance (Ω) seen by the amplifier. The total
impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the
amplifier.
Voice-Acoustic recommends to use the available 4 x 4 mm² Speakon cables for mobile use.
We recommend wiring the basses with at least 4 mm² in installations. The cables of the tops in installations
must be sufficiently dimensioned according to impedance, power and cable length.

Operation
The Alea-4 is exclusively intended for operation with Voice-Acoustic system electronics with internal DSP cont-
roller: the HDSP power amplifiers or powered by the free 800 W amplifier channels of the self-powered subwoo
-
fers.
Make sure the appropriate preset has been selected before connecting the speaker to the system power amp or
self-powered subwoofer.
Using the wrong preset can damage parts of the loudspeaker.
Note: If the Modular-10 is not operated on the intended Voice-Acoustic system electronics, the manufactu-
rer‘s warranty for the loudspeaker expires!
