PROCESSOR PRESETS
The processor is used for the crossover, time alignment of components, equalisation and dynamic processing of the signal.
There are 4 Presets accessed in sequence by a step-through switch.
La Line high-quality, self-powered loudspeakers are designed for a wide range of portable and fixed sound reinforcement
applications. Using the latest technologies, excellent sound, high power and controlled dispersion are combined in a compact
package that’s easy to carry and install .

The La Line components are mounted in a rigid, 15mm birch plywood cabinet coated with a durable paint finish. All drivers
are high-quality, high-sensitivity and made in Europe. Each cabinet is fitted with a sturdy metal grille designed to cope with
the rigours of the road - this is especially important for stage monitor applications. Handles are formed directly into the ply-
wood and positioned at the top of the cabinet, rather than the side, to facilitate removal from flight cases.
Fixing points allow horizontal or vertical mounting using optional brackets and a 35mm polemount socket enables use with a
variety of third party stands. The left hand side of the cabinet is angled at 42º - the optimum angle when used on its side as
a stage monitor. Additionally the HF driver on the La-8 and La-12 can easily be rotated to give the same dispersion charac-
teristic when the cabinet is mounted either horizontally or vertically. The VIETA logo can be rotated accordingly for cosmetic
purposes and to indicate the rotation of the horn
test Technology!
The La Line features the latest in amplifier and processor technology. The Class D amplifiers feature Fixed Frequency PWM-
PPM modulation and are light, clean, power-efficient and matched to the drivers. Each driver in the La-8 and La-12 is pow-
ered by a separate amplifier and separately optimised using DSP. The result is a smooth sound, accurate in the lower mid
frequencies and very low in distortion. Two amplifiers in bridge mode drive the La-112S subwoofer.
LED-indicated features include READY status, SIGNAL present, TEMPerature warning and LIMITing. The limiter is opti-
mised for the system which also features sophisticated overload protection. The INPUT connection is by balanced +4dB XLR
and an XLR THROUGH connector allows multiple systems to be efficiently daisy-chained.

On the full range cabinets these are:-
FRONT - FOH, no subwoofers: low and high frequency shelving equalisation provides a
frequency response contour suitable for music applications.
NEARFIELD - this setting provides a natural, balanced frequency response when the unit
is placed close to listeners in near field and delay applications.
MONITOR - this preset provides a nominally flat response for stage monitor and speech
reinforcement.
X’OVER- adds a 80 Hz High Pass Filter to the system for use with a subwoofer.
On the subwoofer:-
A choice of Low Pass Filter values is offered - 90 Hz, 100 Hz, 110 Hz and 120 Hz. This
allows system optimization with a wide variety of full range cabinets. 90Hz is recom-
mended for use with La-12 and 100Hz recommended for La-8.
PROTECTION CIRCUITS
There are three limiter stages; a clip limiter, responding to excess harmonic distortion, an average power limiter and an aver-
age high frequency limiter to protect the HF driver. Additionally, the La Line features average and peak current protection,
whereby the amplifier stage is shut down should the specified thresholds be exceeded, and over-temperature protection with
a warning phase before shut down. This comprehensive set of protection circuits allows the full potential of the system to be
achieved with minimal risk of damage.
