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. Installation Wall mounting – For attaching brackets (marked “B” on the drilling guide) to the wall, please use appropriate means for mounting to a specified 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 specified 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 ensure that the brackets will be secured to the wall with the appropriate means to ensure similar load condition as specified above. To attach the wall brackets “B” to your amplifier, please use the supplied 3 mm Torx machine screws. Rack shelf mounting – The amplifier can be mounted to a rack shelf or similar by means of the three holes in the bottom marked “A” on the drilling guide. 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 amplifier for more then 10 – 20 mm a fter mounting. Lab.gruppen rack shelf kit – A special dedicated rack mount shelf designed to hold two LUCIA amplifiers is available from Lab.gruppen. It includes all necessary accessories, screws, and mounting instructions. Cooling Ensure that there is sufficient open space on at least two ventilating surfaces (top, bottom, front and rear) of the amplifiers to allow for free air flow. Please refer to the Thermal Dissipation Chart in the full Operation Manual when installing large numbers of amplifiers in air conditioned spaces. LUCIA amplifiers feature intelligent fan control. In low power applications and with good ventilation, the fan will remain off. At moderate power levels, the fan may activate in “whisper mode.” The fan will run at full speed only at elevated output levels, when noise will be masked by the louder program. Operating voltage LUCIA amplifiers 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. Grounding Signal ground is floating 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. This apparatus must be connected to a mains socket outlet with a protective earthing connection.

Front panel (all LUCIA models) The front panel presents the following amplifier status indicators: 1 Standby/On LED indicator – A three-color LED illuminates amber when amplifier is in standby power mode and illuminates green when the amplifier is on. When the amplifier enters Protection mode, the LED flashes 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 infinity to 0 dB. Note: In LUCIA constant voltage mono models (60/1-70, 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 Airow input – Make certain this input is not blocked or covered. Rear panel: Two output low impedance models (LUCIA 60/2, 120/2, 240/2, 60/2M, 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 amplifier). Cables up to 4 mm

(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 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. The following features are located on the rear panel of LUCIA 60/2M, 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.

Rear panel: Mono high-impedance models (LUCIA 60/1-70, 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.

Set-up and Operation Auto Standby / Power-up LUCIA amplifiers do not have a power switch. The amplifier will turn on automatically when AC power is connected to the unit; it will go into standby mode if no signal is present at any input for 20 minutes. When in standby, the amplifier will power up in two seconds when a signal above the preset threshold (-54 dBu default) is present at any channel input. GPIO Configuration: Two Ouput Low Impedance Models Default functionality is as described below for General Purpose Inputs and Output (GPIO). Remote volume control – The default functionality for the GPI is independent control of output volume; please note that this control is in series with the control of from the front panel. There are two ways to do this:

• Connect a GPO from a control device that outputs 0 – 3.3 V – Pins 5 and 6 connect to an internal relay to provide amplifier fault indication. The relay is closed when the amplifier is on and operating normally. The relay opens if a fault in either the output channel(s) or in the power supply interrupts normal operation of one or both channels. Optional GPIO modes – The Matrix models allow other GPIO functions to be enabled by applying changes to the amplifier firmware. See the full Operation Manual for more information. for control. Their grounds also need to be connected; see full Operational Manual for further instructions.

• Connect a remote volume control potentiometer per channel to pins 1 through 4 of the GPIO connector as shown below. (The Vcc voltage output is 3.3 V). – Connect an external contact closure to Ground and GPI2 as shown in the diagram following. Wake-up happens within 0.5 s after contact closure. – Pins 5 and 6 connect to an internal relay to provide amplifier fault indication. The relay is closed when the amplifier is on and operating normally. The relay opens if a fault in either the output channel(s) or in the power supply interrupts normal operation of one or both channels. Optional GPIO modes – The Matrix models allow other GPIO functions to be enabled by applying changes to the amplifier firmware. See the full Operation Manual for more information. Individual volume control

Common volume control

GPIO Configuration: Mono High-Impedance The Default functionality is as described below for General Purpose Inputs and Output (GPIO). Remote volume control – Connect a remote volume control potentiometer to Ground, GPI1 and Vcc as shown in the diagram following. Volume control is after input mixing. (The Vcc voltage output is 3.3 V).

DSP/Matrix Configuration The LUCIA models include a mix matrix and a comprehensive suite of DSP features. In nearly all applications for this type of amplifier, the included features eliminate the need for an external mixer or processing unit. Also, the default DSP and matrix configuration allows “out of the box” installation with no further configuration required for many typical applications. Default preset – The default matrix and DSP configuration is as follows for the M models: SPEAKER 1 = IN 1; volume attenuated with GPI 1 (and front knob) SPEAKER 2 = IN 2; volume attenuated with GPI 2 (and front knob) Out 3 = In 1 (-6 dB) + In 2 (-6 dB); volume attenuated with GPI 1 Out 4 = In 1 (-6 dB) + In 2 (-6 dB); volume is not affected by GPI Software download and installation – Very intuitive configuration software is available that allows selection of which preset to use (optimized for different loudspeakers) and what dynamics processing to use. This application is available for free download from www.labgruppen.com/support. USB connection – A USB connection is provided for firmware updates and downloading presets to the LUCIA. For complete information please refer to the full Operation Manual. – Please refer to the full Operation Manual for detailed information on custom configuration of DSP functions using the LUCIA configuration application. Third-party control – The LUCIA models have a built-in RS-232 serial interface, enabling third-party products to control and monitor LUCIA.
