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.

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

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

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.

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).

Amplifier wake-up – Connect an external contact closure to Ground and GPI2 as shown in the diagram follow-
ing. Wake-up happens within 0.5 s after contact closure.

Amplifier status – 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 channel or in the power supply
interrupts normal operation of one or both channels.

Optional GPIO modes – The LUCIA models allow other GPIO functions to be enabled by applying changes to
the amplifier firmware. See “Control block” in Section 14.5.2.4.

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.

14.1. Introduction

The LUCIA Applciation Browser is a simple, intuitive software editor for configuring the signal matrixing and DSP
features. Amplifier functions are quickly programmed offline and then downloaded to the individual LUCIA units
via the USB port.

Note: 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

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

custom user preset.

Note: Clicking on the “i” icon at the top of the column opens an information window with a description of the

Note that saving multiple units as one Application is for user convenience only; parameters for each device must
be downloaded separately.

Select a device for editing. The selected device shows a blue frame.

Name Inputs, Outputs and GPIO connections. Click on the existing name to edit the text.

Using the small “arrow” beside the selected device, it is possible to get settings from the connected LUCIA.
This action can only be performed if the selected configuration model is identical to the connected LUCIA.

By enabling the small “lock” beside the selected device, it is possible to apply a password to protect settings
applied to the connected LUCIA, preventing unauthorized users obtaining knowledge of system configuration.

Note: The password protection only applies when a user tries to get settings from a password protected LUCIA.
So, users are always able to apply new settings to overwrite password protected settings if desired.

14.5.2 Configuration in block diagram view

When a device is selected, the corresponding Application parameters are shown in the Block Diagram view in the
right-hand column. Click on the Input Block, Matrix Block, Output Block or Control Block to edit parameters.

each input. Select the option appropriate for your application.

14.5.2.2. Matrix block

The Matrix feature allows any of the inputs to be routed to any output. The level for each matrix route is adjustable
from 0 to -30 dB using the fader to the right of the matrix.

Manual routing – Click in the box to select the desired input-to-output routing.
Preset routing – Matrix settings appropriate for many applications are available as presets using the scroll-down

menu under Presets below the Matrix box.
Level setting – Select the desired matrix route (framed in blue) and use the fader to set the level.

Note: The Matrix selection function is disabled when a GPI function is assigned as Source Selector.
(See Section 14.5.2.4). This prevents possible confusion and errors.

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.

Adjustable delay – It is possible to add a delay (0-120 ms) to the overall latency on each output.
Adjustable power output – The low impedance LUCIA models enable the option to adjust maximal output power

Output Level
Source Selector
Mute All
Wake

RS232
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 RS232 is selected, it is possible for third-party products to remote control and monitor LUCIA via RS232 serial
interface. For more information on RS232 serial interface usage, please refer to the “LUCIA Serial Dongle – RS232
Quick Start Guide”, which can be downloaded from http://labgruppen.com/support/download-quick-start-guide

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

The GPO is not reconfigurable; the Control Block shows current functionality.

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.

16. FAQ

16. FAQ

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

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.

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,

ts).

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

ill result in incremental delays.

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

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

deliver. In LUCIA two output low impedance 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.
