Enhanced flexibility in 70 V installations

Combining premium audio performance with extraordinary exibility,
Lab.gruppen’s innovative LUCIA (Localized Utility Compact
Intelligent Amplication) introduces a decentralized approach to AV
systems design. Power, limiting, control and I/O are conveniently
placed where needed, offering a cost-efcient and scalable solution
that often eliminates the complications and added costs of a
centralized equipment room. All LUCIA ampliers incorporate a
digital, rmware-controlled front end coupled to a robust, durable
and highly efcient Lab.gruppen output stage. This model brings the

inherent advantages of the LUCIA concept to a range of constant

voltage applications.

Fast installation, reliable operation

LUCIA ampliers install quickly using the supplied wall-mount bracket
(for on-wall placement e.g. behind video displays, or on ceilings, or
cabinet walls or under tables etc) or on rubber feet on any at surface.
Pole-mount and rack-mount brackets are available as options. All
connections are detachable, and level setting is available on front­panel potentiometers as well as via GPI. An advanced protection
scheme protects the amplier and connected loudspeakers from
potential damage caused by clipping, thermal overload, or extremely
low line voltage. LUCIA’s built-in matrix automatically mixes the
balanced and unbalanced inputs with optimized gain structure.
Selection or mixing of inputs is accommodated by front panel
potentiometers or by conguration of the GPI.

▸ GPIO – Remote control for output level and instant wake

from sleep mode as default; other options possible via the
configuration software

▸ Conguration sof tware – Windows and Mac software wizard for

initial set-up (connection via USB)

▸ Fail-safe operation – Comprehensive short circuit, thermal and

under-voltage protection

▸ Intelligent fan control – Silent at idle and extremely quiet at low

output levels

▸ Selectable high-pass lter – Rear switches for ON/OFF and

50 Hz or 80 Hz filter; this is in series with the customizable input
and ouput EQs (which are flat from the factory)

▸ ENERGY STAR® qualied

efficiency standards

Integrated DSP for enhanced flexibility

All LUCIA models incorporate comprehensive DSP features, including
look-ahead limiter and exible equalization which often eliminate the
need for external mixers and processors in many applications - saving
time and money. A software wizard facilitates fast set-up via USB, a
feature that can this reuse previous set-up les.

Green credentials

LUCIA ampliers are ENERGY STAR qualied, making them ideal for
installation in projects seeking energy efcient certications. LUCIA
ampliers automatically enter standby mode after a 20 minute period
with no signal input, consuming less than 1 watt. Automatic power-up
occurs within one second after an input signal is sensed, a feature that
often eliminates any need for power sequencers or controllers. If no
loss of initial audio is required (e.g. for an important message), a contact
closure on GPI-2 can turn on the amplier before audio playback.
