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.

Tip
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.

CONTROLS AND FUNCTIONS
5) -6dB
SELECTOR
This selector allows to reduce all the analog XLR [6] input levels by 6 dB at the same
time to compensate for the high output levels on the mixers or other audio devices.
When the input signal level bar on the display [1] remains always at full scale, this
means that the input signal level is excessive and a -6 dB attenuation is
recommended.
In the Option menu it is possible to check when the selector is activated
6)
INPUT CONNECTORS “A” AND “B”
Inputs balanced at line level.
Capable to accept XLR male connectors
7)
OUTPUT CONNECTORS “1”, “2”,” 3”, “4”, “5” AND “6”
Outputs balanced at line level.
Capable to accept XLR famale connectors
Be careful to correctly connect each output to each speaker or
amplifier, according to the settings of each channels, to avoid
damages and malfunctions
“AES/EBU” Section
8) INPUT
CONNECTOR
In addition to the analog audio inputs, a SPDIF-AES/EBU (AES3) digital audio input
is also provided. It can be selected via the setup menu.
Such input requires a balanced connection trough an XLR connector with a 110 ohm
twisted 3-wires cable.
9)
“OUT” OUTPUT CONNECTOR
This connector allows to forward audio signals available at the digital or analog
inputs or outputs. The source must be set by means of the Option menu
The connection must comply with the same standard of the input [8]
RDNET Section
10)
DATA INPUT CONNECTOR
Data input RJ45 connector.
11)
“DATA LINK” OUTPUT CONNECTOR
RJ45 connector for data output used for serial link in cascade.
12)
“ON” INDICATOR LIGHT
This green indicator turns on only when the AC26N has recognized the RDNET
main unit and it is connected to it via computer.
13)
“ACTIVE” INDICATOR LIGHT
This yellow indicator flashes when data transmission between RDNET and the
device is active.
