Rear panel: Mono high-impedance models
(LUCIA 120/1-70 and 240/1-70)
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 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.

5 USB port – Connects to external computer for downloading DSP
presets. See "DSP/Matrix Configuration" 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 firmware 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.
8 High pass frequency – Select 80 Hz or 50 Hz for high pass
cutoff frequency. This filter is in series with what gets configured in
the Application Browser software.
9 HPF switch – Select ON or bypass for the high pass filter.
