2. INTRODUCTION

ALMAcard DIGITAL PROCESSOR FOR SPEAKER SYSTEMS

The ALMAcard is a digital signal processor on a plug-in card for DPA Series amplifiers featuring

2 inputs and 4 outputs for audio, USB connectivity and two ports of remote volume control (0-10VDC).

Main features

•2 audio inputs and 4 audio outputs

•DSP with 24-bit quantization and 48kHz sampling frequency

•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:

oControls of gain, phase, MUTE, etc., per input and output

o8 pEQ (parametric filters) per input and 8 pEQ per output

oButterworth, Linkwitz-Riley or Bessel crossovers on the inputs and outputs (up to 48

dB/oct)

oDelays on the inputs and outputs

oCompressor/peak limiter on the inputs (with make-up gain)

oCompressor/peak limiter on the outputs (with make-up gain)

oCompressor/RMS limiter on the outputs (with make-up gain)

o2 LINK groups available to link output channels

o1 LINK group available to link input channels

•System templates for the creation of user setups:

oT1: 2 x 1 stereo way

oT2: 2 stereo ways

oT3: 4 mono ways

oT4: 4 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

•Locking with password protection

3. INSTALLATION

The ALMAcard can be mounted in the rear bay of an Ecler DPA-Series amplifier. The amplifier

will redirect its audio signal inputs to the ALMAcard inputs, taking internally two of its outputs to feed the

stereo amplification circuitry. The other 2 processor outputs (STACK) will be available for connection to

other amplifiers or external devices.

The ALMAcard installation procedure in a DPAamplifier is the following:

1. Unplug the amplifier.

2. Unscrew and remove amplifier's cover and back plate.

3. Remove the two jumpers from the input stage connector. Keep the jumpers and the back plate in safe

place. You'll need them to use the amplifier without the filter.

4. Insert the filter in its back panel location and plug its cable (see diagram).

5. Screw the filter and the cover.

CAUTION: Filter installation must be done by a qualified technician.

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. CONNECTIONS

STACK connectors (1, 2)

Correspond to the third and fourth audio outputs of the ALMAcard integrated processor, available

for connecting to other amplifiers or external devices.

REMOTE connectors (3, 4)

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 from each REMOTE port are selected with the EclerCOMM Manager

application software.

USB Connector (5)

A type-B USB connector (1) is used to connect the ALMAcard to a PC and perform the

unit management and control from EclerCOMM Manager software.

5. CONFIGURATION/EclerCOMM Manager SOFTWARE

The ALMA24/ALMAcard device can be configured only through the Windows© EclerCOMM

Manager application, since the ALMA24/ALMAcard has no local controls.

The EclerCOMM Manager application is available for free download from the Ecler web site.

5.1. Installation and connection with ALMA24/ALMAcard

Once you have downloaded the software, it is recommended that you first connect the USB

cable supplied with the equipment between a computer's USB port and the ALMA device USB port. After

this, the installation is performed by running the downloaded installer file and following the steps

displayed on screen.

Once installed, run the EclerCOMM Manager application to open its graphical interface, where

you need to select, in the first place, the type of device you want to connect, in this case

ALMA24/ALMAcard. This is done by accessing the Device -> Select menu:

Then by clicking on the Connect with device button, the communication can be established with

the hardware device, after choosing the synchronization option (SEND to send the current configuration

to the hardware device or GET to load the hardware device's current settings in the application):

The F2 key allows you to rename your hardware device:

5.2. Menus

•File: options to transfer configuration files from the device to your computer or storage

device, retrieve saved files, etc.:

Note: A configuration file contains the configuration that was active in the device at the time

of saving, but not the content of its 20 presets. When you retrieve a configuration file

saved to disk, connect the equipment and transfer this configuration to the hardware (SEND

option), that configuration is not stored in any preset, unless it is saved (see Device menu)

In addition to the 20 user-writable presets, there are 4 predefined templates (not rewritable)

to start a user configuration from, which are quite common in this type of device:

oT01: 2 x 1 stereo way

oT02: 2 stereo ways

oT03: 4 mono ways

oT04: 4 mono outputs

•Device : options to select a type of device to connect to (Select), recall and activate one of

the 20 presets in the device memory (Recall Preset), save the current configuration in the

device memory (store Preset) and update the device firmware using a compatible file (the

latest versions of compatible firmware for each of our digital devices are available on the

Ecler web site):

The options for preset recall and storage are also available directly at the top of the control

panel:

•Help : gives access to the user manual, to the Ecler website, and displays the version

information of the application:

•

5.3. Signal generator and remote ports

The built-in signal generator can feed an input to send its signal to the DSP processing chain in

order to perform a spectral analysis and/or adjustment of parameters depending on the acoustic

characteristics of the room and equipment.

Its parameters are:

•SIGNAL: type of signal generated, Sinewave (sine wave with a variable frequency), Polarity

(specific waveform to determine the correct polarity of the speakers, with variable frequency),

White Noise and Pink Noise.

•FREQUENCY: frequency of the Sinewave or Polarity signal

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).

Each preset saves the function assigned to the REMOTE ports at the time of saving (so different

presets can contain different functions for the same REMOTE port).
