4. DESCRIPTION & FEATURES
HADA Series is a family of digital amplifiers, with different power levels: HADA-4B150 with 125W, HADA-4B250 with 250W, HADA-4B400 with 400W, HADA-4B500 with 500W and HADA-4B750 with 750W.
All the models include 4 amplified channels that support Hi-Z and Low-Z loads down to 2, 2.7 or 4 ohms, depending on the model.
A powerful DSP allows to manage the routing and the processing of the inputs and outputs through the HADA DSP Manager Software. Routing functionality includes a matrix mixer for selecting which input channels to allocate to the outputs. Processing includes 10-band EQ, HP and LP filters, limiters, multi-band compressors, delay and factory and end-user configurable presets.
All models include a remote output volume control via the front potentiometers. It is also possible to connect external potentiometers in the rear panel, for the remote volume control of the outputs. Via an external contact, it is also possible to perform a general mute of the outputs, for emergency functions or integration purposes.
Another control option is network control via TCP/IP which allows to control the amplifier from third party control systems through customized user interfaces.

6. INSTALL & CONNECT
The equipment must be correctly grounded (ground resistance, Rg = 30 Ohm or less). The environment must be dry and dustless. Do not expose the unit to rain or water splashes, and do not place liquid containers or incandescent objects like candles on top of the unit.
Do not obstruct the ventilation grilles with any kind of material. If the device requires any intervention and/or connection/disconnection, it must be first powered off.
Do not handle the speaker output terminals with your device turned on, there are high voltages. The output cabling should be connected by a qualified technician. Otherwise only use pre-made flexible cables. There are no user serviceable parts inside the amplifier.
Non-compliance with the instructions or neglecting warnings may cause malfunction or even damage the unit.
· Avoid turning on the device without the speakers connected to its outputs and without having previously set the volume/gain controls to minimum level.
· Always use shielded cables to make connections between devices. · In an amplifier, avoid placing the speaker output cables close to other signal cables
(micro, line…). This may cause the system to oscillate, damaging the amplifier and speakers.

6.1 Location, Assembly and Ventilation

HADA series devices have a 19″ rack format (2RU). It is very important not to enclose the amplifier or expose it to extreme temperatures as it generates heat. It is also necessary to encourage the airflow through the ventilation holes of the chassis. The ventilation system forces the airflow, front to back, through the unit. If multiple products are installed in the same rack or in a cabinet with closed doors, it is highly recommended to install fans in their upper and lower ends for a forced airflow from the bottom up. This upward air flow will help to dissipate the heat generated inside.
It is advisable not to place power amplifiers under other appliances, but upon these ones. Hada amplifiers can be stacked one on top of the other, leave one rack unit empty every 3 to guarantee an adequate heat sink.
Regular maintenance of dust removal is highly recommended as dust can impede airflow and hinder heat dissipation.

Always respect the relative polarity for outputs (+ and – on each output connector), wiring and speakers.
6.4.1 Out Configurations
HADA DSP Manager software allows to configure the amplifier to operate in high impedance/bridge mode, or low impedance.
Select the appropriate operation mode to do not damage the loudspeakers. Depending on the model in use, never connect loads below 2, 2.7 or 4 ohms when working in low impedance mode.
HiZ and Bridge modes must use the first or the second pair of channels. Please connect the loudspeakers as reported on the silkscreens when HiZ mode or Bridge mode is required.
Make sure to match the impedance of the total load connected to the loudspeakers, when working in low impedance for a correct performance. If impedance values do not match, select the closer one above.
6.4.1.1 Operation Example
AMP OUT1-2: HiZ-100V When OUT 1-2 are configured in bridge, use both + pins to connect the loudspeakers. The + on the left is the positive.
AMP OUT3: LoZ-8ohm AMP OUT4: LoZ-4ohm When LoZ is selected the channels operate independently with declared maximum power. The connection cable that joins the amplifiers outputs and the loudspeakers must be of good quality, sufficient section and as short as possible. This is most important when the distances to cover are long ones i.e., up to 10 meters it is recommended to use a section not inferior to 2.5mm2 and for superior distances 4mm2.

6.5 Remote Volume
HADA rear panel provides four remote control ports, labelled “REMOTE VOL 1-4”, to which you can connect analogue devices such as the WPa series wall panels or common 10 Kohm linear potentiometers.

7.2 HADA DSP Manager Configuration
Once the physical connections have been made, the HADA units must be connected using the HADA DSP Manager software.
The HADA network interface comes from the factory in DHCP client mode. This means that if a DHCP server is present in the network, it will automatically provide the IP address to the device. In the absence of a DHCP server, as in standard networks, the HADA network interface will take a random address in the 169.254.x.y class.
If your PC’s network card is also configured in DHCP mode, through the automatic discovery of the HADA DSP Manager software you can easily find all your networked amplifiers which will appear as a list in the main software window. Only one software interface can be connected to the amplifier at a time.
Once the list of amplifiers in the network is ready, you can click on the arrow to the right of each one to open the configuration window.

7.4 Recovery Mode
In case that a firmware issue appears, or a firmware update fails, the HADA unit will automatically load an emergency firmware called “Recovery Mode”. This allows to connect with Ecler HADA DSP Manager and update the firmware again with the correct firmware of each HADA model. When the unit is in this special state, all the front LEDs of the unit (Prot., Thermal, Ext. Mute, Data and ON) will blink at the same time. Audio signal will be processed by the DSP and a special limitation of all the outputs will avoid damaging the amplifier modules.
To exit from recovery mode, please enter the administrator credentials and update the firmware of the unit.
Each HADA unit needs to be updated with the right firmware related to each model.

HADA DSP MANAGER

9.1 Updates
· Current version: V4.0.0 (October 2024) o New graphic visualization and restrictions for user profile. o Improved management of output mode (Bridge mode) o 2 Ohm and 2.7 Ohm loads supported (Depending on model) o Maximum Delay time increased for Input and Outputs (2s) o Minor bug fixes and performance improvements.
· Previous version: V3.9.1 (March 2024) o Official release version of HADA Series.
9.2 First Steps
To access the HADA DSP Manager software, it is necessary to download and install the Windows application by clicking on this link.
First, make sure that both devices are physically connected to the same local area network (LAN), and configured as DHCP clients.
0 HADA device is in DHCP network configuration mode by factory default. If you have a router/switch with a DHCP server (see the specifications for your device), network configuration is automatic so there is no need for you to do any re-configuration.
If new software releases are installed, 0it is necessary to uninstall the previous version via the Windows program manager.

9.3 Automatic Connection using a Computer
1. Connect the HADA device to the router/switch or point to point by using a CAT5 or higher cable.
2. Set your computer to DHCP client mode by selecting “obtain an IP address automatically” in the network settings (this is the usual default setting).
3. Open the HADA DSP Manager application. All HADA units connected to your network will be listed.
In the event that some HADA unit is static IP configured instead of the factory network settings, it will be necessary t0o configure the computer’s network card the same network range in order the application locate all units.
4. Once HADA units connected to the network appear listed on the screen, click on the arrow to the right of the unit to open the configuration window of the selected one.
