DESCRIPTION & FEATURES

AURA Series is a family of analogue amplifiers, with different power levels: AURA-2L150 two channels, 2×150 W RMS @ 4 Ω, AURA-4L150 is a multichannel, 4×150 W RMS @ 4 Ω, AURA-8L150 is a multichannel, 8×150 W RMS @ 4 Ω, AURA-2H150 two channels, 2×150 W RMS @ 70/100V, and AURA-4H150 is a multichannel, 4×150 W RMS @ 70/100V.

AURA Series are built with the highest robustness for long lasting performances, with special power supply circuitry designed for optimized electrical consumption. All AURA are 100% silent featuring convection cooling system.

AURA Series also features the possibility of linking channels to the first input by selecting it on the rear panel, adjustable Auto Standby level, overload and thermal protection, PFC and anti clipping system.

Main Features

Euroblock input and output connectors.
Link to input 1 available.
Volume control knobs on front panel, that can be blocked via switches accessible from the bottom cover.
High efficiency (Class D).
Auto Standby function.
Convection cooling (fanless, 100% silent).
Thermal protection.
Overload protection.
Anti-clip system.

PANEL FUNCTIONS

Front Panel

Power Switch: the equipment is switched on by default just switching to ON the front panel power switch.
ON LED: lights up in green colour when the unit is powered ON.
Auto Standby indicator LED: lights up in green colour when the Auto Standby function is enabled.
Auto Standby button: enables / disables the Auto Standby function (low power consumption mode, managed by pairs of channels).
Control knobs (1-8 upon model): each front panel LEVEL knob allows to control the volume of the correspondent amplified audio outputs.
The front panel knobs can be disabled by means of the VOL Bypass switches -accessible with a thin screwdriver- from the bottom face of the chassis.
Signal indicator LED (per channel): indicates signal presence in the amplification output. These indicators light up in green colour when the input signal exceeds -40dBV threshold.
Clip indicator LED (per channel): lights up in red colour when the input signal exceeds -0,9dBV.
Protect /Thermal. indicator LED (per channel): lights up in red colour when the general protection circuit of the channel is activated, or in orange colour when the temperature limiter is in operation, with fast blinking when temperature reaches 83 °C (181.4 °F) or steady when the temperature reaches 125 °C (257 °F) and in this case the equipment goes into protection mode.
Standby indicator LED (per pair of channels): lights up in orange colour when a couple of adjacent channels enter into Standby (low power consumption) mode.
Auto Standby threshold can be selected, for every 2 adjacent channels , by means of an internal jumper, between -40db / -50 dB values.
Link indicator LED (per channel): lights up in white colour when the link function is activated = the channel gets its input audio signal from IN1 in the rear panel (same signal that CH1 gets), instead of getting it from INX, where X is the channel count index.up when the maximum power is reached.

Rear Panel

Mains socket base
Amplified outputs, OUT 1-2, or 1-4, or 1-8 (upon model), 2-pin Euroblock or 3 pin Euroblock (Low Impedance or High Impedance, respectively, upon models)
Analogue inputs, IN1-2, or 1-4, or 1-8 (upon model), 3-pin Euroblock, balanced.
Link button for INX to IN1 (X=2 to 8, upon models).

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.

Location, Assembly and Ventilation

AURA series devices have a 19″ rack format (1RU).

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.

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.

Please ensure that there is always, at least, one free rack unit between an AURA amplifier and other equipment installed above and below it in the rack cabinet. This is essential for the fanless convection ventilation to work properly and thus ensure correct operation of the amplifier throughout its lifetime.

Regular maintenance of dust removal is highly recommended as dust can impede airflow and hinder heat dissipation.

Mains Connection

AURA operates on alternating voltages from 100-240 V @ 50-60Hz (±10%). 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 front panel, there is an on/off switch for the unit.

ON Led on the frontal panel lights up when unit is switched on.

To enable/disable the Auto Standby mode (per pairs of channels) just push the Auto Standby button on the front panel. The Auto Standby LED will light in green accordingly.

Do not allow the mains cable to run parallel to the shielded cables carrying the audio signal, as this may cause humming.

Analogue Input Connections

AURA rear panel provides analogue, balanced, line level signal inputs. The selection of hardware inputs and it’s routing to the unit’s amplified channels are performed from its physical connections and LINK button.

Signal input connectors are 3 position screw terminal block. The wiring is:

Live or direct signal > Pin +
Cold or inverted signal > Pin –
Ground > Pin

For unbalanced connection short-circuit pin to pin − as reported on the picture.

Amplified Output Connections

The rear panel is fitted with two position screw terminal block for each amplified output (low impedance models) or with three position screw terminal block for each amplified output (high impedance models, 70/100V outputs).

Always respect the relative polarity for outputs (+ and – on each output connector), wiring and speakers.

Out Configurations

Select the appropriate operation mode to do not damage the loudspeakers. Never connect loads below 4 ohms when working in low impedance mode.

Make sure to match the impedance of the total load connected to the loudspeakers, when working in low impedance for a correct performance.

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.

START-UP & OPERATION

Start-up

When the front 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 green, the device is operational.

In a complete audio installation, it is important to start up the equipment in the following sequence:

sound sources
mixer
equalizers
active filters
processors
power amplifiers.

To turn them off the sequence should follow an inverse pattern.
