CONNECTIONS

Analog Audio Connections

Balanced connections allow to minimize the cable induced noise, so cable can be longer. Such connections may be used both on inputs and outputs.

XLR connector must be cabled with pin 1 to ground, pin 2 to hot (+) and pin 3 to cold (-). With shielded cables, connect the shield to pin 1.

XLR-XLR e XLR-Jack 1/4"(6,3 mm) connection cables can be used to connect the AC26N.

Input XLR - female Pin 2 = Positive/Hot+VE Phase Pin 1 = Screen/Ground/Earth Pin 3 = Negative/Cold+VE Phase Output XLR - Male Pin 1 = Screen/Ground/Earth Pin 2 = Positive/Hot+VE Phase Pin 3 = Negative/Cold+VE Phase

The unbalanced connections can also be used. However, the cable induced noise increases and cable length must not exceed 5 meters.

Such connections may be used both on inputs and outputs.

Unbalanced connection may lower the level of the input signal up to 6dB; in order to overcome this drawback, connect pin 3 to ground, although this can increase the noise.

Input XLR - female Pin 2 = Positive/Hot+VE Phase Pin 1 = Screen/Ground/Earth Pin 3 = Link to Pin 1 Output XLR - Max Pin 1 = Screen/Ground/Earth Pin 2 = Positive/Hot+VE Phase Pin 3 = Link to Pin 1

Digital Audio Connections (AES/EBU)

AES/EBU (AES3 protocol) is and a balanced input, electrically insulated by means of a transformer. It allows carrying two audio channels in a single two-wires shielded cable. The cable characteristics are: twisted, 3 poles, impedance 100 ohm, shielded, equipped with XLR connector (AES3 standard)

RDnet

Each RDNet port on Control 2 and Control 8 can be connected to maximum 32 cascade-connected compatible devices.

In the example below, the control unit RDNET CONTROL 2 port is connected to the DATA INPUT of an AC 26N, whose parallel DATA LINK output is sent to the input of the next AC26N.

In the example, [n] is a number between 3 and 32 (maximum limit for the devices connected to a sub-network)

The overall length of a CAT5 sub-network cable cannot exceed 900 meters.

The connector must be connected as follows:

1 - Available for other functions (for example: audio +)
2 - Available for other functions (for example: audio -)
3 - Available for other functions (for example: analog ground)
4 - digital ground
5 - digital ground
6 - Available for other functions (for example: power supply)

a) INPUT AND OUTPUT CHANNELS

The input and output connectors are identified by the same information provided on the screen printing located on the device rear side.

b) SIGNAL LEVEL

It shows the signal gain The increased signal intensity is expressed in decibels (dB). Such parameter can be selected in the range from -80.00 dB to +20.00 dB in steps of 0.01 dB.

An increase of 6 dB is approximately equal to doubling - in a linear scale - the signal voltage level

If the gain exceeds 0 dB the signal is amplified, while if the gain is lower than 0 dB the signal is attenuated.

c) SIGNAL DELAY

The reproduced audio signal may be delayed to perform an acoustic alignment. This compensates for the different positions of the speakers during the installation and the sound reproduction; it is expressed in ms. The parameter can be selected in the range from 0.0 ms to 72.9 ms in steps of 0.1 ms.

The following formula can be used to align an audio signal:

Delay = (GAPx1000)/344

Delay = ms (in milliseconds)

GAP = distance between speaker and reference point (in meters)

Speed of sound = 344 m/s

d) MUTE

Each channel can be individually muted. The same command can be activated in the Meters Menu.

NOTE: The general mute has the highest priority with respect to the muting of individual channels.

e) Phase

It performs a phase rotation of 180^ with respect to the input signal.

Such phase rotation allows the optimization, in special way for low frequencies in complex installations.

f) EQUALIZATION

This control opens the menu controlling the single channel equalization. It is mainly used to correct one or more frequencies that must be reduced or increased.

The AC26N manages 12 filters for each individual channel input and output, with three different kinds of configuration:

• PEQ Equaliser (peaking equalizer); ideal to identify, isolate and correct only a certain range of frequencies. All frequencies pass, only those around the centre frequency are increased and decreased, for a given bandwidth and set gain.
• High-shelf Equalizer. All frequencies pass, but frequencies above the selected cut-off frequency are increased or attenuated by the given gain.
• Low-shelf Equalizer. All frequencies pass, but frequencies below the selected cut-off frequency are increased or attenuated by the given gain.
