Power ampli ers are capable of producing hazardous output
voltages. To avoid electrical shock, do not touch any exposed
speaker wiring while the ampli er is operating. External wiring
connected to the speaker terminals shall be installed by a
quali ed person, or ready-made leads or cords of appropriate
capacity shall be used. As the ampli er outputs produce high
voltage, do not connect or disconnect speaker cables when
the mains power is on.
3.1.3 Radio interference
A sample of this product has been tested and complies with
the limits for the European Electro Magnetic Compatibility
(EMC) directive. It also has been tested and found to comply
with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference from

for help.
• Reorient or relocate the antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
3.1.4 Speaker damage
Many loudspeakers can be easily damaged or destroyed by
overpowering them. Always check the speaker’s continuous
and peak power capabilities. Although the ampli er’s
attenuators can be used to reduce the overall gain, an
increase of the input signal can still result in full output power,
which may cause damage to connected speakers.
3.1.5 Maintenance
For safe and reliable operation, any dust collected in the front
panel should be removed regularly. In rare circumstances,
accumulated dust could ignite due to high internal
temperatures and cause a re. If the front is clogged so that

6. Unpacking and visual checks
6. Unpacking and visual checks
Every Lab.gruppen amplier is carefully tested and inspected before leaving the factory and should arrive in perfect
condition. If any damage is discovered, please notify the shipping carrier immediately. Save the packing materials
for the carrier’s inspection and for any future shipping.
7. Installation
7.1. Wall mounting
For attaching brackets (marked “B” on the drilling guide; see inside the shipping box) to the wall, please use
appropriate means for mounting to a specied load of 3 kg minimum on each screw. Ensure that all four screws
are secured properly to the wall. For drywall mounting, use a woodscrew (3.5 mm diameter with 25 mm minimum
length) and 4.5 mm drywall plug with specied maximum load of greater than 3 kg (e.g. Molly E22412). This
method of mounting is evaluated for North America according to UL/CA60065.
For mounting on surfaces other than drywall, please ensure that the method of mounting is suitable for the wall
material. Also, be certain that the brackets are secured to the wall with the appropriate means to ensure similar
load condition as specied previously. To attach the wall brackets “B” to your amplier, please use the supplied
3 mm Torx machine screws.
7.2. Rack shelf mounting
The amplier can be mounted to a rack shelf or similar by means of the three holes in the bottom marked “A” on
the drilling guide (see inside the shipping box). Use a 4 mm diameter machine screw (not supplied), ensuring that
the length of the screw is suitable for the thickness of the shelf. The screws used should not penetrate into the
amplier for more than 10-20 mm after mounting.
7.3. Lab.gruppen rack shelf kit
A special dedicated rack mount shelf designed to hold two LUCIA ampliers is available from Lab.gruppen as an
accessory. It includes all necessary accessories, screws, and mounting instructions.

8. Cooling and fan operation
Ensure that there is sufcient open space on at least two ventilating surfaces (top, bottom, front and rear) of the
ampliers to allow for free air ow. Please refer to the Thermal Dissipation Chart (Section 15.4) when installing large
numbers of ampliers in air conditioned spaces.
LUCIA ampliers feature intelligent fan control as shown in the following table.
Table interpretation: In a typical application, if a loudspeaker has a sensitivity of 87 dB SPL at 1 m for 1 W, then the
fan will stay silent for SPL levels up to ~95 dB (87 + 7.8) at 1 m distance from the loudspeaker; at 2.5 m from the
loudspeaker will maintain levels up to 87 dB with the fan off. If the sustained average output is higher, the fan starts
in whisper mode; however, this shouldn’t be an issue as the program SPL is so much higher, likely above 80 dB no
matter where you are in the room.
9. Operating voltage
LUCIA ampliers have a universal power supply that operates on AC mains from 100 – 240 V at 50 or 60 Hz.
The power receptacle on the rear panel accepts the supplied IEC cord which terminates in a connector
appropriate for the country of sale.
10. Grounding
Signal ground is oating via a resistor to chassis, and therefore grounding (earthing) is automatic. For safety
reasons, never disconnect the earth (ground) pin on the AC power cord. Use balanced input connections to avoid
hum and interference when longer input cables (more than about 1 m/ 39”) are used.
