Output Connections; Ethernet Port; Remote Control Ports For Attenuation; Remote Control Ports Connection - Ecler NZA Série Notice D'utilisation

3.4. Output connections

The rear panel OUTPUTS section is fitted with two position screw terminal block (9) for each amplifier
channel (4 or 6, depending on model). Always respect the relative polarity for outputs (+ and - on each output
connector), wiring and speakers. In bridge mode, follow the wiring and polarity standard indicated near the output
screw terminal block and labeled as "BRIDGE".
SINGLE / PARALLEL / BRIDGE operating modes are selected from EclerNet Manager control application.
Please refer to the EclerNet Manager software manual for more information.
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 2.5mm

3.5. Ethernet port

An RJ-45 connector (10) allows connecting the equipment to an Ethernet network and its management from
EclerNet Manager software. Please refer to the EclerNet Manager software manual for more information.

3.6. Remote control ports for attenuation

NZA series rear panel provides 4 or 6 (depending on model) remote control ports (11) labeled as "REMOTE
CONTROL". With EclerNet Manager application, you can assign a port to one or more channels of the amplification
unit in order to remotely attenuate the input signal volume (and therefore the output volume of the affected channels)
remotely.
The maximum signal level in each amplification channel, and therefore its output volume (using or not remote
attenuation and outside DSP processing done from EclerNet Manager application) is determined by the position of your
front panel rotary control (1).

3.7. REMOTE CONTROL ports connection

The signal remote attenuation level for each input channel can be set by using 3 types of external devices
connected to the rear panel REMOTE CONTROL ports:
a) Using a remote potentiometer with nominal resistance between 10kΩ and 50kΩ.
b) Using a device that generates a control voltage from 0 to 10V DC.
c) Using remote relays/dry contacts.
NOTE: you can connect up to 16 REMOTE CONTROL ports in parallel to the same hardware control
potentiometer. You have to merge the ground of all amplifiers belonging to these ports.
The connection cables can be up to 500m long if a section of 0.5mm
