INSTALLATION

Location, mounting and ventilation
GENIO has been specially designed both for placement as a desktop unit and for placement in 19″ rack furniture, occupying a height unit (mounting kit included for surface and standard rack cabinets). GENIO does not require ventilation due to its low power consumption, however, it is recommended that the unit is not completely enclosed or exposed to extreme temperatures. Fresh air should be allowed to pass through the ventilation holes in the chassis, leaving at least one free rack unit between each piece of equipment and those installed above and below it in the rack frame.

If the installation consists of several units in the same rack or is carried out inside cabinets closed by means of doors, it is highly recommendable to equip them with forced upward ventilation, installing fans at their lower and upper ends. This upward flow of ventilation will favor the dissipation of the heat generated in its interior.

Mains connection and power on
GENIO is powered from the mains by its universal external power supply. This external power supply has several interchangeable connectors (mains plugs): American, European, British and Chinese formats. On the front and rear panel there is a LED ON that gets lit when the unit is in operation. Do not allow the external power supply cable intermingles and runs parallel to the shielded cables carrying the audio signal, as this may cause humming.

CABLE CONNECTIONS

It is recommended to make all audio connections with devices off or on stand- by, whether input devices such as audio sources or devices connected to the mixer outputs such as power amplifiers.

Audio input connections

GENIO has the following audio inputs, with the following types of connection:

INPUT 1 and 2: balanced mono signal, with 3-pin female XLR connector + ST jack (combo connector) and with Euroblock connector. Control of the input sensitivity of the signal by means of the SENS switch (0, -20, -40 dB).
- COMBO connector:

XLR/ Jack TRS/ Euroblock

Live or direct signal > Terminal 2 / Tip / +
Cold or inverted signal > Terminal 3 / Centre ring / –
Ground > Terminal 1 / Base / ⊥
- Microphone connection: The microphone connection for the Euroblock connector is shown in the diagram below.

On the rear panel of the unit there is a PHANTOM ON/OFF switch, which provides phantom power (18VDC) to inputs 1 and 2 for use with microphones that require it, usually condenser microphones.

INPUT 3 and 4: unbalanced stereo line signal, with RCA connectors and 3,5mm stereo mini-jack connector.
- Dual RCA Connector: Connect your stereo sound source (CD players, Smartphones, radio tuners, streaming players, etc.) directly using a cable that delivers the left (L) and right (R) channels to the unit’s white and red RCA connectors, respectively.
RX: RJ45 connector for the reception of the signal sent from the TX port of another remote GENIO unit, by means of a CAT5 cable or higher. It also receives remote power in case of activation of the REMOTE POWER switch in the remote TX unit.

Output Audio Connections
GENIO has the following audio outputs, with the following types of connection:

OUT A and B: main output. Balanced stereo or mono line signals, with Euroblock connector on the rear panel. Depending on the position of the SRC and MODE switches, the output will be configured in the following ways:
POSITION

SWITCHES

| OUTPUT CONFIGURATION

(OUT A/B = TX A/B)

---|---
SRC = IN 1 – IN 2

MODE = ST

| OUT A = IN 1

OUT B = IN 2

SRC = IN 1 – IN 2

MODE = MONO

| OUT A = IN 1 + IN 2

OUT B = IN 1 + IN 2

SRC = IN 3 – IN 4

MODE = ST

| OUT A = IN 3

OUT B = IN 4

SRC = IN 3 – IN 4

MODE = MONO

| OUT A = IN 3 + 4

OUT B = IN 3 + 4

SRC = ALL

MODE = ST / MONO

| OUT A = IN 1 + IN 2

OUT B = IN 3 + IN 4

TX: a copy of outputs A and B is delivered to the RJ45 connector to send the signal to another remote GENIO unit via a CAT5 cable or higher. It also sends the remote power in case of activation of the REMOTE POWER switch.
RX A/B: Audio outputs connected directly to the A and B signals received on the RX port from a remote TX unit, with Euroblock connectors.

Other connections

TX and RX: if two GENIO units are interconnected via a CAT5 link or higher, it is possible to send the audio signal from one unit to another, in addition to being able to send/receive remote power from one unit (TX) to another (RX).

About balanced and unbalanced audio connections
If a balanced output channel is connected to an amplifier or audio device with a balanced input, the + (Pin 2), – (Pin 3), and ⊥ (Pin 1) terminals must be connected from point to point between the two devices. ecler-GENIO-Analog-
Preamps-and-Mixers-fig-7

If you connect a balanced output channel to an amplifier or device with unbalanced audio input, leave the – (Pin 3) terminal unconnected. ecler-
GENIO-Analog-Preamps-and-Mixers-fig-8

If an unbalanced output channel is connected to an amplifier or audio device with an unbalanced input, the signal ( tip) and ground (base) terminals must be connected point to point between the two devices. ecler-GENIO-Analog-
Preamps-and-Mixers-fig-9

If an unbalanced output channel is connected to an amplifier or audio device with a balanced input, the unused output pin (terminal –) must be short- circuited to ground. Otherwise, the output signal will not have the right level or quality. ecler-GENIO-Analog-Preamps-and-Mixers-

OPERATION AND USE

Start-up

Once all the connections have been made, connect the GENIO unit to an external PSU. The ON LED will light up in green.

In a complete audio installation it is important to start the equipment according to the following sequence: sound sources (microphones, music players etc.), mixers, audio processors and finally the power amplifiers. To stop them, the sequence must be reversed. In this order, the transients produced by the turning on or off of the devices will not affect the next one in the chain, remaining inaudible.

Switch configuration
The default settings for the equipment switches are as follows:

SENS: switches at 0dB
MODE: ST
SRC: IN 1 – 2
PHANTOM INPUT 1 &2: OFF
REMOTE POWER: OFF

To change the input sensitivity (SENS), move the corresponding input switch to set it to 0, -20 or -40dB.

To change the configuration of the OUT A/B outputs, the input selection switches (SRC) and mono/stereo output switches (MODE) can have the following positions with their corresponding output configuration:

POSITION

SWITCHERS

| OUTPUT CONFIGURATION

(OUT A/B = TX A/B)

---|---
SRC = IN 1 – IN 2

MODE = ST

| OUT A = IN 1

OUT B = IN 2

SRC = IN 1 – IN 2

MODE = MONO

| OUT A = IN 1 + IN 2

OUT B = IN 1 + IN 2

SRC = IN 3 – IN 4

MODE = ST

| OUT A = IN 3

OUT B = IN 4

SRC = IN 3 – IN 4

MODE = MONO

| OUT A = IN 3 + 4

OUT B = IN 3 + 4

SRC = ALL

MODE = ST / MONO

| OUT A = IN 1 + IN 2

OUT B = IN 3 + IN 4

To activate the phantom power to the microphones as needed, the PHANTOM IN 1&2 switch must be turned ON. In the same way, to activate the remote power supply to another GENIO unit, the REMOTE POWER switch must be turned ON.

OBSERVATIONS

Ground loops
It must be ensured at all times that the signal sources that reach the unit, as well as all the devices that are connected to its output, do not have the grounds interconnected, that is to say that the gounds never reach them by two or more different paths, since, in this way, buzzes could be produced that would even interfere with the quality of the sound reproduction.

The shields of the cables, if they are connected to a chassis, must never be connected to each other. This way we avoid the formation of ground loops.

Background noise
GENIO has been designed to obtain the lowest possible background noise. Regardless of the electronic design, the background noise will depend directly on the correct use and installation of the unit.

Cleaning

The cover should not be cleaned with solvents or abrasive substances as there is a risk of damage to the screen printing. To clean it, use a cloth dampened with water and a neutral liquid detergent and then dry it with a clean cloth. Under no circumstances should water be allowed to enter through any of the holes in the appliance.
