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 4 ohms.
5. PANEL FUNCTIONS 5.1 Front Panel ON/Standby Button: the equipment is switched on by default just switching to ON the rear power switch. • When the ON LED of the front panel is lit in white, the device is operational. •...
Mute indicator LED: lights up in white colour when the amplified output is muted. Prot. indicator LED: lights up in red colour when any protection of the power module is active (along with the mute LEDs of the channels that are failing), or when the standby mode is active (along with the ON LED).
(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.
6.2 Mains Connection HADA operates on alternating voltages from 90 to 264V and 47 to 63Hz. This device is equipped with an oversized power supply capable of adapting without any type of adjustment to the mains voltage of any country in the world. On the rear panel, there is an on/off switch for the unit.
6.3 Analogue Input Connections HADA rear panel provides analogue, balanced, line level signal inputs. The selection of hardware inputs and their routing and mixing towards either amplifier channel is performed from its embedded web application. For further information, please refer to HADA DSP Manager chapter.
6.4 Amplified Output Connections The rear panel is fitted with two position screw terminal block for each amplified output. 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.
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. These ports allow to control the volume of the output channels: each REMOTE VOL input is associated with its own corresponding output channel.
6.7 Ethernet Ports The RJ-45-type ETHERNET connector on the rear panel, named NET, allows the equipment to be connected to an Ethernet network, or directly to a computer or other device with an Ethernet interface, point-to-point. This connection enables, within a local network, the following: •...
7. START-UP & OPERATION 7.1 Start-up When the rear panel Power switch is ON, the amplifier is powered, and it will automatically switch on. When the ON LED of the front panel is lit in white, the device is operational. To enter in standby mode, press and hold the ON button until all LEDs on the front panel blink once.
7.2 HADA DSP Manager Configuration Once the physical connections have been made, the HADA units must be configured 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.
7.3 Bridge Mode and Hi-Z Mode Bridge or HiZ mode, which allows 100V/70V line loudspeakers to be connected, must be set via the HADA DSP Manager software. Please configure the correct output mode via software before connecting the loudspeakers line: •...
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.
