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
electrical equipment. This product use
s radio frequency
energy and, if not used or installed in accordance with these
operating instructions, may cause interference to other
equipment, such as radio receivers. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment causes harmful interference
to radio or television reception (determined by turning the
equipment on and off), the user may be able to correct the
interference by one or more of the following measures:
• Check if
the affected unit complies with the EMC limits for
immunity, (CE-labeled). If not, address the problem with
the manufacturer or supplier. All electrical products
sold in the EC must be approved for immunity against
interference.
• Consult the dealer or an experienced radio/TV technician
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. Warnings
Many loudspeakers can be easily damaged or destroyed by
overpowering them. Always check the speaker’s continuous
and peak power capabilities. The low impedance Lucia models
have the ability to set output power limitation, allowing Lucia
output power to be adjusted to ensure that it does not exceed
loudspeaker specifications.

are secured properly to the wall. For drywall mounting, use a woodscrew (3.5 mm diameter with 25 mm minimum
reater 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

7.2. Rack shelf mounting

the length of the screw is suitable for the thickness of the shelf. The screws used should not penetrate into the

8. Cooling and fan operation
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
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
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.

2 Signal present/limit/clip indicators – A three-color LED illuminates to provide channel status information as
follows:
Green – Signal is present at the input and the channel is operating normally.
Amber – Limiting is active on the channel. Limiting is engaged when:
• The channel reaches the voltage limit as determined by the automatic Voltage Peak Limiter (VPL) setting
• Maximum current output is reached
• Mains voltage cannot maintain rail voltage
Red – Channel is clipping either at the input or in DSP
3 Signal attenuators – A signal attenuator is provided for input channels 1 and 2. Attenuators are adjustable over
Note: In LUCIA constant voltage mono models (60/1-70, 120/1-70 and 240/1-70), the attenuators act as an input
select and mixer by adjusting each input level that goes to the single output channel.
– Make certain this input is not blocked or covered.

loss, especially if mixing to mono in in the matrix.
2 Unbalanced audio inputs (1 & 2) – Connect unbalanced inputs (e.g. local video screen output, CD player) to
the RCA (cinch/phono) inputs. Balanced and unbalanced inputs feed an internal analog mixer with optimized gain
settings to ensure that full level can be reached no matter which input is used. A balanced and an unbalanced
input can be connected simultaneously and “the choice of input” is determined by which device
is currently playing.

Correct polarity (+, -) and ground terminations are shown on the rear panel.
2 Unbalanced audio inputs (1 & 2) – Connect unbalanced inputs (e.g. local video screen output, CD player)
to the RCA (phono) inputs. Note: Balanced and unbalanced inputs are in parallel; only one pair of inputs should be
connected at one time.
3 Speaker outputs – Connect to loudspeakers in a 70 V or 100 V distributed system. Note that if the transformer has marking for 100 V, then the same total power will be delivered as with 70 V. However, since limiting
engages at -3 dB relative to 100 V, the power delivered per loudspeaker will be half of the marking on the
loudspeaker transformer. Consequently, taps should be set to twice the desired power.
4 GPIO/Remote connector – Connect external control and status monitoring devices using the six-pole
Euroblock connector. See “GPIO Configuration” in Set-up and Operation section following.
