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 warrantee.
1.1. Precautions
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30
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
* EclerNet Manager software is available on www.ecler.com.
