LUCIA Operation Manual rev 1.0.0

6. Unpacking and visual checks

Every Lab.gruppen amplier 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 specied 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 specied 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 specied previously. To attach the wall brackets “B” to your amplier, please use the supplied 3 mm Torx machine screws.

7.2. Rack shelf mounting

The amplier 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 amplier 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 ampliers 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 sufcient open space on at least two ventilating surfaces (top, bottom, front and rear) of the ampliers to allow for free air ow. Please refer to the Thermal Dissipation Chart (Section 15.4) when installing large numbers of ampliers in air conditioned spaces.

LUCIA ampliers 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 ampliers 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.

LUCIA Operation Manual rev 1.0.0

11. Front panel

1 2 3 4

The front panel presents the following amplier status indicators:

1 Standby/On LED indicator – A three-color LED illuminates amber when amplier is in standby power mode and illuminates green when the amplier is on. When the amplier enters Protection Mode, the LED ashes red and the speaker outputs are muted. See “Protection mode” in Section 13.3.

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 – innity to 0 dB.

4 Airow input – Make certain this input is not blocked or covered.

LUCIA Operation Manual rev 1.0.0

12. Rear panel

8 3

The following features (1-7) are located on the rear panel of all LUCIA ampliers:

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. Observe polarity to avoid low frequency cancellation 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.

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 amplier). Cables up to 4 mm2 (12 AWG) can be accommodated. Observe polarity to avoid low frequency cancellation loss. Note: Bridge mode connection is not supported.

13. Set-up and operation

Individual volume control

Common volume control

13. Set-up and operation

13.1. Auto standby / Power-up

LUCIA ampliers do not have a power switch. The amplier 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 amplier will power up in 0.9 seconds when a signal above the preset threshold (-54 dBu default) is present at any channel input.

In order to avoid issues with the signal being too low relative the threshold it is generally better to use full level from the source and to reduce the gain in the LUCIA instead using the front controls, GPI or in the matrix.

13.2. GPIO conﬁguration

All LUCIA models provide the default functionality described below for General Purpose Inputs and Output (GPIO).

Remote volume control – The default functionality for the GPI is independent control of output volume (output 1 on GPI1 and output 2 on GPI2). Please note that this control is in series with the control on the front panel. There are two ways to do this:

A. Connect a GPO from an external control device with a control voltage output of 0 – 3.3 V. The ground of the control device must be connected to the ground pin of the LUCIA GPI connector.

B. 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). If you want the link the control, then you simply link GPI1 and GPI2 together with a jumper cable.

Amplier status – Pins 5 and 6 connect to an internal relay to provide amplier fault indication. The relay is closed when the amplier is on and operating normally. The relay opens if a fault in either channel 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 amplier rmware. See “Matrix Block” in Section 14.5.2.2.

Note: Transfer of preset data is a one way process. Presets can only be downloaded to the LUCIA

13.3. Protection mode

The ampli er enters Protection mode when thermal conditions or current draw exceed safe limits. When the ampli er cools below the thermal threshold, or nominal load conditions are restored, the ampli er exits Protection mode automatically.

IMPORTANT – Protection mode often results from excessive operating levels, improper load conditions or insuf cient ventilation. Always check these conditions any time a LUCIA ampli er enters Protection mode.

14. LUCIA application browser

14.1. Introduction

The LUCIA Application Browser is a simple, intuitive software editor for con guring the signal matrixing and DSP features of LUCIA matrix models (LUCIA 120/M and 240/M). Ampli er functions are quickly programmed of ine and then downloaded to the individual LUCIA units via the USB port.

Note: Transfer of preset data is a one way process. Presets can only be downloaded to the LUCIA device; you cannot upload settings back to the Application Browser. Therefore, if you want to connect to a device at a later time and make changes, it is important to save the settings in the computer running the application browser when you program the LUCIA. This way they can be recalled, edited and downloaded to the LUCIA device at a later time.

Factory presets for common applications include input and matrix settings plus output equalization pre-optimized for compatible Tannoy loudspeakers and generic loudspeaker types. All parameters are user adjustable, allowing creation of custom user presets that may be stored for future use. An online “sync mode” allows real-time setting of parameters – a useful feature for adjusting loudspeaker response for room acoustics using the four-band parametric equalizers.

14.2. Software download and installation

The LUCIA Application Browser software is available for free download from the Support section of the Lab.gruppen web site. Select Software & Firmware from the left-hand menu. You must be registered to access the download pages.

Under LUCIA, select LUCIA Application Browser. Follow the on-screen instructions. Note that there is no separate installation wizard. When downloading the compressed (zipped)  le, simply save to any convenient location (desktop, documents) where write privileges are available.

If more than one device is shown, the device currently selected for parameter con guration or downloading of a preset will be shown with a blue frame.

Block Diagram column – The right-hand column displays the various options and tools available for con guring the device. Four icons are displayed in a block diagram format: Inputs, Matrix, Outputs and Control. When an icon is selected, the applicable con guration tools appear in the column below.

14.4. Factory presets

All factory presets are displayed in the Application Selector column. The number of factory presets available will depend on the version of software installed, as new presets will be added to later versions. Factory presets are developed by TC Group product specialists to provide quick set-up and optimum performance in a variety of common AV installations. New users are advised to review all available factory presets to determine which one is closest to the requirements of a speci c installation. This will minimize the amount of time required to create a custom user preset.

Note: Clicking on the “i” icon at the top of the column opens an information window with a description of the currently selected preset application. Descriptions also may be added when creating custom user presets.

Low Cut 12* (second order 12 dB per octave high pass Butterworth  lter) Low Cut 6 ( rst order 6 dB per octave high pass Butterworth  lter) Low Shelve 12 (Shelving boost or cut with 12 dB per octave slope) Low Shelve 9 (Shelving boost or cut with 9 dB per octave slope) Low Shelve 6 (Shelving boost or cut with 6 dB per octave slope) Low Shelve 3 (Shelving boost or cut with 3 dB per octave slope) Band (normal parametric EQ for which the width is de ned in octaves) High Shelve 3 (Shelving boost or cut with 3 dB per octave slope) High Shelve 6 (Shelving boost or cut with 6 dB per octave slope) High Shelve 9 (Shelving boost or cut with 9 dB per octave slope) High Shelve 12 (Shelving boost or cut with 12 dB per octave slope) High Cut 6 ( rst order 6 dB per octave low pass Butterworth  lter) High Cut 12* (second order 12 dB per octave low pass Butterworth  lter)

*: If you wish to implement a 24 dB per octave high or low pass Linkwitz-Riley  lter, then simply select two 12 dB  lters and set them to the same frequency.

Edit the output  lters by (as appropriate) selecting an alternative  lter type and entering new values in the parameter boxes. (Only those parameters applicable to the  lter type will be accessible.)

To save the custom  lter, click on OK. To exit without saving changes, click CANCEL.

ADLC (Automatic Dynamic Loudness Contouring) – ADLC is a sophisticated, DSP-controlled function that maintains optimum sound balance regardless of listening level. ADLC may be enabled or disabled using the radio buttons to the right of each speaker preset.

14.5.2.4. Control block

The Control Block allows the user to de ne functions for each of the two GPI ports of the device by selecting a function from the MODE menu. The functions available for each port are:

Output Level Source Selector Mute All Wake No Function (disabled)

When Wake or Mute functions are selected in MODE, the PRESET box shows a description of the function. These are described as Open/Close referring to that the only thing needed is a switch connected between GND and the GPI pin. So, in this scenario Close means that the GPI gets a voltage very close to zero (GND) and Open means that the voltage is close to Vcc (thanks to an internal connection).

When Source Selector or Output Level functions are selected, available options are shown in the PRESET box.

The GPO is currently not recon gurable; the Control Block shows current functionality.

14.6. Saving and storing custom applications

14.6.1. Saving applications

Once you have completed conguration of a custom Application, click on the Save button. A dialog window will open which allow you to enter a le name, author and a description of the Application preset. Click on the Save button in the dialog window to save the Application le.

The new custom Application will appear at the top of the list in the left-hand column.

NOTE: If you click on another Application from the left-hand application menu before saving the le, a prompt will appear asking if you wish to save the le.

IMPORTANT: Do not close the main Application Browser window (quit the program) before saving an Application le. The window will close immediately with no prompt, and all entered information will be lost.

14.6.2. Storing and sharing applications

Regardless of the location of the Application Browser (desktop, documents etc.), all Application les will be stored at C:\Users\username\Documents\LUCIA Applications. Application les may be shared by copying to or from this folder.

14.7. Programming a LUCIA device

To program a LUCIA device, rst select the desired application from the list in the left-hand column. If the Application includes more than one device, select the desired device. It will show with a blue frame.

Connect a USB cable from the computer to the LUCIA device. The PROGRAM button will show as enabled as soon as the connection is established.

14. LUCIA application browser

Press the Program button

A con rmation dialog will show when the settings have been successfully transferred to the device. The dialog also shows an option to Enable Synchronization. If you want to further edit parameters in real time, click the button and then click “OK.” (See Online Mode following.) If you do not want to do real-time edits, simply click “OK.”

14.8. Online mode

To enter Online Mode, click the “Enable Synchronization” button when programming a LUCIA device. (See Section 14.7.)

A device connected in Online Mode shows in the Application Browser with an orange frame.

In Online Mode, any changes made to parameters in the Application Browser are transferred in real time to the connected LUCIA device. A circular animation shows in the selected device while updating is in progress. Online Mode is particularly helpful for adjusting output equalization while listening to or measuring the connected loudspeaker(s).

To exit Online Mode, press the “Sync Enabled” button or select another device.

14.9. Upgrading the ﬁ rmware in a LUCIA device

As features are added, the  rmware in the LUCIA will eventually require upgrading. While the LUCIA is connected to the host computer, the Application Browser will check that the  rmware version will support the selected application before the application is programmed to the device. If an upgrade is required, then a wizard will guide you through the upgrade procedure with step-by-step instructions. Each step will be veri ed by the wizard to keep this procedure simple and secure.

In the unlikely event that it should fail to update, restart the Application Browser and see what it says; if required put the LUCIA in update mode and try again.

15.3. External control via GPI: Connection and components

The default function for GPI is level control, a linear potentiometer with a value between 1 k to 100 k ohm can be used. As the GPI is internally pulled high it will default to full level if no potentiometer is connected. If the cable is a shielded twistred pair, then the shield should be connected to ground. Alternately 3 tightly twisted leads can be used. The potentiometer should be connected so that the wiper (the sliding contact) is at the Vcc side of the potentiometer for maximum level and at the GND side for Mute.

A resistor ladder selector can be used to perform selection of up to 4 different alternatives. The total impedance should be between 1k and 100k ohm and one way to do it is as illustrated below (this is also how the Lab.gruppen accessory is made).

The May 2014 release of the Application Browser software allows customization of selections and voltages for each of the select positions.

16. FAQ

Is the LUCIA power stage inherently bridged as on E Series, thereby allowing asymmetrical loading?

No, the power output limit per channel is xed on LUCIA. The amplier cannot be bridged and there is no way to use power on one channel that is not being used on the other, as with Lab.gruppen’s E Series. However, the channels are automatically optimized when it comes to peak voltage, enabling one channel to deliver the full rated power into 2 ohms and the other channel into 8 ohms.

What is the meaning and importance of “Input headroom for clip” in the technical specications?

This is the level at which the input signal will reach full level on the input to the DSP. Above this level, the signal will be severely compressed by an analog soft-clip circuit.

How many inputs can be driven by a LUCIA M line output?

Each LUCIA balanced line level output can drive up to 6 inputs in parallel; these can be any combination of LUCIA, E Series, or C Series ampliers (or other 20 kOhm balanced inputs).

16. FAQ

Why is there latency (delay) through LUCIA?

The latency through a LUCIA is 9.15 ms (acoustically equivalent of 10 ft or 3 m). This is primarily due to the lookahead limiters and to the multiband mastering compression used in our ADLC algorithm, which adjusts for the nonlinearities of the ear (ISO226). The 9.15 ms of latency is below what is detectable as out-of-sync when used in video sound applications. Nevertheless, in some applications, it is preferable to drive multiple LUCIA units in parallel rather than in a series (‘daisy chain’) conguration, as this will result in incremental delays.

What limiter circuits are incorporated into LUCIA, and how do they operate?

Following is a simplied description of the LUCIA limiters:

• Short term (<60 ms), look-ahead voltage peak limiter - The threshold of this limiter is automatically trimmed by

an instantaneous impedance measurement when the amplier goes out of standby. This automatic adjustment ensures that the threshold does not exceed the rated power or the maximum current that the amplier can deliver. In LUCIA M models, alternate presets may be used that designed for a lower power output than the full output allowed by the default preset.

• Medium term limiter - This limiter is inserted to avoid clipping if the power supply rail sags.

• Long term (>0.5 s) - This limiter is inserted to prevent thermal problems.
