Front panel (all LUCIA models)
The front panel presents the following ampliier status indicators:
1 Standby/On LED indicator
– A three-color LED illuminates
amber
when ampliier is in standby power mode and illuminates
green
when the ampliier is on. When the ampliier enters Protection
mode, the LED lashes
red
and the speaker outputs are muted.
For more information on Protection mode, please refer to the full
Operation Manual.
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 a range of minus
ininity to 0 dB.
Note:
In LUCIA constant voltage mono models (120/1-70 and
240/1-70), the attenuators provide an input select and mixing
function by setting the level from each input that goes to the single
output channel.
4 Airlow input
– Make certain this input is not blocked or covered.
Rear panel: Two output low impedance models
(LUCIA 120/2, 240/2, 120/2M, 240/2M)
1 Balanced audio inputs (1 & 2)
– Connect balanced inputs using
3-pole Euroblock connectors. 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 loudspeakers with nominal
impedance of 2, 4, 8 or 16 ohms. Maximum connector current rating
is 41 Arms (exceeding capacity of the ampliier). Cables up to 4 mm
2
(12 AWG) can be accommodated. Observe polarity to avoid low
frequency cancellation loss.
Note: Bridge mode connection is not supported.
4 GPIO/Remote connector
– Connect external control and status
monitoring devices using the six-pole Euroblock connector. See
“GPIO Coniguration” in Set-up and Operation section following.
5 USB port
– Connects to external computer for downloading DSP
presets. See “DSP/Matrix Coniguration” in full Operation Manual.
Connection requires cable with a Mini B type connector (included).
6 UTIL (Utility) switch
– Recessed switch places unit in update
mode for irmware updates. The switch must be pushed in and held
down while the USB connector is being inserted to activate update
mode. Refer to the full Operation Manual for more information.
7 AC line input
– Connect the included IEC power cable.
The following features are located on the rear panel of
LUCIA 120/2M and 240/2M only:
8 Balanced audio inputs (3 & 4)
– Connect balanced inputs using
3-pole Euroblock connectors. Correct polarity (+, -) and ground
terminations are shown on the rear panel.
9 Matrix line outputs
– Connect balanced line output cable using
3-pole Euroblock connectors Correct polarity (+, -) and ground
terminations are shown on the rear panel.
