Important Note; Precautions; Introduction - Ecler NZA Série Notice D'utilisation

1. IMPORTANT NOTE

Congratulations! You are the owner of a carefully designed and manufactured equipment. We thank you for
trusting on us and choosing our NZA multichannel amplifier with Ethernet remote control.
In order to obtain maximum operativity and perfect functioning order, it is most important to carefully read all
considerations taken into account in this manual before connecting this amplifier.
We recommend our authorised Technical Services if any maintenance task should be needed so that
optimum operation shall be achieved.
NZA series amplifiers come with a 3-year warranty.

1.1. Precautions

The amplifier should have an earth connection in good conditions (earth resistance, Rg=30Ω 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.
In case there is some type of intervention and/or connection-disconnection of the amplifier, it is most
important to previously disconnect the mains power supply.
Do not manipulate the output terminals to the loudspeakers when the amplifier is switched on, there are
voltages up to 400Vpp. 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.

2. INTRODUCTION

The NZA series of multichannel amplifiers consists of 4 models with 4 channels and 2 with 6 channels:
•
NZA4-70: 4 x 80 W RMS
•
NZA4-180: 4 x 190 W RMS
•
NZA4-400: 4 x 420 W RMS
•
NZA4-700: 4 x 730 W RMS
•
NZA6-70: 6 x 80 W RMS
•
NZA6-180: 6 x 200 W RMS
All models are equipped with convection cooling, without fan, a feature allowing a very quiet operation,
suitable for installation in noise sensitive environments.
Channels can independently operate or can be linked, two operating modes being then available: BRIDGE
(one pair behaves as a single higher power amplifier) or PARALLEL (one pair has two amplified outputs, but both
receive and deliver identical signals, simultaneously managed).
In addition, it incorporates important technological innovations concerning digital processing and remote
management via Ethernet, turning it into the perfect candidate to address mobile applications and fixed installations,
both centralized and distributed, requiring high level remote control and monitoring and integration with
standard Ethernet networks. NZA amplifiers include as standard an EclerNet internal module for DSP processing
and remote management, allowing physical connection between the amplifier and an Ethernet network as well as its
remote management and supervision from any point of it, using Windows® EclerNet Manager (*) software. Please
refer to the EclerNet Manager software manual for more information.
Other features of this series are:
•
Volume remote control ports (1 per channel)
•
Soft Start function, except for 4-70 and 6-70 models
•
Integrated DSP processing (8-band parametric EQ, crossovers, delay, compressor, etc.) remotely
controllable via Ethernet (EclerNet Manager software (*))
•
Auto-Standby function (automatic sleep mode when there is no audio input signal)
•
Clipping prevention function ("anti-clip") with 3 levels of performance
•
Screw terminal block for connection
