2. INTRODUCTION

ALMA26 DIGITAL PROCESSOR FOR SPEAKER SYSTEMS

The ALMA26 is a digital signal processor featuring 2 audio inputs and 6 audio outputs, USB

connectivity and two ports of volume remote control (0-10VDC).

Main features

 2 audio inputs and 6 audio outputs, with XLR connectors  DSP with 24-bit quantization and 48kHz sampling frequency  2x20 characters LCD display in front panel  4 setup keys + digital rotary encoder to navigate in the menus and set the parameters  1 LED backlit key (MUTE function) for each input and each output (8 in total)  Level meters for each input and each output  2 REMOTE ports to control the volume of the inputs or outputs (0-10VDC) from external devices,

such as WPm series panels

 USB interface and compatibility with EclerCOMM software (free download from

http://www.ecler.com/en/products/software.html

)

 Processing:

o Controls of gain, phase, MUTE, etc., per input and output o 4 pEQ (parametric filters) per input/8 pEQ per output o Butterworth, Bessel or Linkwitz-Riley crossovers on the outputs (up to 48 dB/oct) o Delays on the inputs and outputs o Compressor/limiter on the outputs (with make-up gain) o 3 LINK groups (linking output channels)

 System templates for the creation of user setups:

o T1: 3 x 1 stereo way o T2: 2 stereo ways + 1 stereo way o T3: 3 stereo ways o T4: 4 mono ways + 2 mono auxiliaries o T5: 5 mono ways + 1 mono auxiliary o T6: 6 mono outputs

 Each system template automatically sets the operating and control mode of the channels and

their settings, including the LINK group they pertain to. Example: in a stereo setup, the settings applied to a left channel output will be automatically applied to the output which is assigned to the right channel, and vice versa (same LINK group)

 User presets: 20  Editing names (labels) of inputs, outputs, presets and device  Two front panel lock modes with password protection (full lock or excluding MUTE keys).

3. INSTALLATION

The ALMA26 can be mounted in a standard 19” rack (482.6 mm) taking up one height unit

(44 mm).

For professional use it is recommended to place the processor in the same rack as the power

amplifiers.

Given the small power consumption of the unit, no ventilation is required. Nevertheless, it is

advisable not to expose the unit to extreme temperatures as well as ensure a dry and dust-free operating environment.

It is important not to place the processor next to electrical noise sources such as transformers,

voltage dimmers, motors, etc. or their mains supply cables. The metal cover of the device should never be removed under any circumstance for that same reason.

The ALMA26 operates with alternate current (AC) between 90 and 264V at 47 to 63Hz. This

device features an oversized power supply which adapts itself to any mains voltage around the world, without the need of manual adjustment.

Even though the noise produced by powering up is minimum, it is always advisable to follow this

power up sequence: signal sources, mixing unit, processor and, finally, power amplifiers. The power down sequence must follow exactly a reverse order. By closely following this sequences, all peaks or transients produced by switching on and off devices do not affect the next devices in the chain and, of course, never reach the loudspeakers, which are extremely sensitive about this.

Ground Loops

Care should be taken, so that the different mechanical and electrical grounds, as well as the chassis and ground connections arriving to the device, to be independent from each other.

Ground loops can be easily detected through a low frequency hum noise (50Hz). Depending on the level of this noise, it can interfere on the music quality.

Audio connections

Usually, many people do not care enough about the quality of cables. Many times, because of a bad connection or bad quality cables, there can be important problems during the music reproduction.

4. FRONT PANEL

Input and output VU meters

Each input (1) or output (2) VU meter allows you to read the level of the audio signal, with 40dB, -

20dB, 0dB and CLIP indications.

MUTE keys

These keys, one for each input (3) or output (4), allow to mute the selected input or output by

pressing them. The LED integrated in the key itself indicates the status of its MUTE function (lit red = MUTE ON).

LCD display (5)

Display showing numeric data and setup menus, settings and device information.

Encoder-type rotary selector

The rotary selector (6) allows you to modify the value of the parameters displayed on the LCD

screen, by increasing or decreasing them depending on the direction of rotation. The rotary ENCODER features a push function ("SHIFT") in addition to the rotation function. The SHIFT function allows you to access advanced setup modes and alternate functions of the four navigation keys of the front panel (reverse silk-screen printing: EXIT, CANCEL, RECALL and SAVE/ENTER).

Setup keys

The four front panel setup keys allow you to navigate through the various menus and their pages,

and access special features thanks to certain combinations of keys pressed simultaneously:

The left and right MENU keys (7, 8) allow you to scroll through the different pages of the unit's

setup menus.

The left and right PARAM keys (9, 10) allow, within a menu and a page, to select the parameter whose value has to be modified with the rotary encoder (6): the name of the targeted parameter flashes in the display while its value can be edited.

The special combinations of the setup keys are:

 Left and right MENU simultaneously for 2 seconds: access to the unit's SETUP menu (see

chapter 9)

 Left and right PARAM simultaneously for 2 seconds: access to the unit's front panel

locking/unlocking and password management (see chapter 10)

 SHIFT + left MENU (EXIT): bring back to the main screen, from any menu  SHIFT + right MENU (CANCEL): undo the last parameter editing and recall the value as

before the change

 SHIFT + left PARAM (RECALL): load one of the presets (device setups) stored in the memory  SHIFT + right PARAM (SAVE/ENTER):

o SAVE: save a preset (device setup) into memory o ENTER: confirm a critical modification (e.g.: password change)

 Right MENU, kept pressed while powering up the unit: load preset #1, designed to be edited

and saved in order to be used as booting setup. This operation is allowed even when the unit's front panel is locked with a password

 Holding down the SHIFT key while powering up the unit: displays the "Power OFF to recover

factory defaults" message. After turning off and on again, default parameters ( factory defaults) are restored, erasing all user data, settings and presets from the unit's memory

USB Connector

A type-B USB connector (11) is used to connect the ALMA26 to a PC and perform the unit management and control from EclerCOMM Manager software.

5. BACK PANEL

The back panel features the following connections:

Mains, fuse and power switch (15, 16, 17)

Due to the switched mode power supply, the operating voltage range is 90V – 264V AC, with a frequency between 47Hz and 63Hz. Before powering up the unit, make sure that the ALMA26 is correctly connected to ground in a facility that complies with local regulations.

Input (12) and output (13) connectors

The ALMA26 has two balanced audio inputs (CH1 and CH2) on 3-pin female XLR connectors (pin 1 to ground, pin 2 to signal + (positive) and pin 3 to signal – (negative)). The ALMA26's signal output is performed through six balanced outputs (OUTPUT1-6), on 3-pin male XLR connectors. As for inputs, the connectors are configured with the pin 1 to ground, pin 2 to signal + (positive) and pin 3 to signal – (negative).

REMOTE connectors (14)

The A and B REMOTE connectors allow you to simultaneously control the volume of one or multiple inputs, or one or multiple outputs through a WPm series wall panel or similar (0-10VDC). The inputs or outputs controlled through each REMOTE port are selected using the device setup menu (front keys and LCD display) or from EclerCOMM Manager software.

6. MAIN SCREEN/PRESET MANAGEMENT

After powering up the unit, its main screen displays the name or label of the device (default is

ALMA26) on the top line of text. The lower line shows the number and name (LABEL) of the active preset or template:

An asterisk to the right of the preset number indicates that it has been modified and not yet saved

in the memory of the ALMA26.

6.1. RECALL PRESET MENU

The ALMA26 has 6 operating templates, which are used as a starting point for the configuration

of an operating mode:

o T1: 3 x 1 stereo way o T2: 2 stereo ways + 1 stereo way o T3: 3 stereo ways o T4: 4 mono ways + 2 mono auxiliaries o T5: 5 mono ways + 1 mono auxiliary o T6: 6 mono outputs

It is therefore possible to recall one of these templates, to edit its parameters and save the

resulting setup as a PRESET or user memory.

System templates are displayed on the screen with the Txx prefix, where xx is the template

number (between 01 and 06), followed by its name or LABEL. These files are not rewritable.

User presets are displayed on the screen with the Pxx prefix, where xx is the preset number

(between 01 and 20), followed by its name or LABEL. The default name of all user presets is USER PRESET, but it can be modified when you save one of them in memory.

The procedure for recalling a preset or a user template is the following one:

 From the main menu, press SHIFT + RECALL  The RECALL PRESET message is displayed and a preset number is flashing

The equipment will be temporarily unlocked, until it remains 2 minutes without any activity on the front panel or returns to the lock menus (left and right PARAM simultaneously for 2 seconds) to confirm or modify the lock mode, in which case it will go back to the password request (the same or a new one), which will be active starting from your validation (SHIFT + ENTER).

To permanently unlock the equipment, access the lock menu and select the UNLOCK ALL mode as new locking mode.

11. CLEANING

The control panel must not be cleaned with any dissolvent, abrasive or petroleum derived substance else paint and silk-printing could be damaged. Whenever cleaning should be necessary use a soft cloth slightly wet with water and neutral liquid soap. Be careful that no liquid gets into the unit through its orifices. Never use sharp or erosive objects to scratch the control panel.

Explicación de los Símbolos Gráficos

El símbolo del relámpago con una flecha en la punta y dentro de un triangulo equilátero, tiene el propósito de alertar al usuario de la presencia de un voltaje peligroso y sin aislar dentro del aparato, y de una magnitud tal que puede constituir riesgo de descarga eléctrica para las personas.

El símbolo de exclamación dentro de un triangulo equilátero, tiene el propósito de alertar al usuario de la presencia de instrucciones importantes sobre la operación y mantenimiento en la información que viene con el producto.

Los símbolos de relámpagos dibujados cerca de los terminales de salida se utilizan para alertar al usuario del riesgo de descargas peligrosas. Los conectores de salida que podrían plantear algún riesgo se indican con este símbolo del relámpago. No toque los terminales de salida mientras que el amplificador esté encendido. Hacer todas las conexiones con el amplificador apagado.

ADVERTENCIA: para prevenir choques eléctricos o riesgo de incendios, no exponer este equipo a la lluvia o la humedad.

INSTRUCCIONES IMPORTANTES DE SEGURIDAD

1. Lea estas instrucciones

2. Guarde estas instrucciones

3. Preste atención a todas las advertencias

4. Siga todas las instrucciones

5. No utilice este aparato cerca del agua

6. Límpielo solamente con un paño seco

7. No bloquee ninguna abertura para ventilación. Instálelo de acuerdo con las instrucciones del fabricante

8. No lo instale cerca de fuentes de calor como radiadores, estufas u otros aparatos que produzcan calor, incluidos amplificadores.

9. No elimine el propósito de seguridad del cable de corriente polarizado o con conexión de tierra. Un cable polarizado tiene dos bornes, uno más ancho que el otro. Un enchufe con conexión a tierra, tiene dos bornes y un tercer borne conectado a tierra. Este tercer borne está previsto para su seguridad. Si el cable proporcionado no entra en su enchufe, consulte con un técnico electricista para reemplazar ese enchufe obsoleto.

10. Proteja el cable eléctrico de ser aplastado, en especial en la zona de los conectores, los receptáculos de los mismos y en el punto en el que el cable sale del aparato.

11. Utilice solamente los accesorios especificados por el fabricante.

12. Desconecte el aparato durante las tormentas eléctricas o cuando no lo vaya a usar durante periodos largos de tiempo.

13. Para cualquier reparación, póngase en contacto con un servicio técnico cualificado. La reparación es necesaria cuando el aparato no funciona con normalidad o ha sido dañado por cualquier motivo, ya sea porque el cable o el enchufe estén dañados, porque se hayan derramado líquidos o hayan caído objetos dentro del aparato, o porque el aparato haya sido expuesto a la lluvia o se haya caído.

14. Desconexión de la red: apagando el interruptor de POWER (17) todas las funciones e indicadores del amplificador se pararán, pero la completa desconexión del aparato se consigue desconectando el cable de red de su conector (15). Por esta razón, éste siempre debe tener fácil acceso.
