OPERATING
IMPORTANT: Before making any connections, make sure that the power unit is not connected to the mains.
Power stage 40426 needs to be correctly connected before receiving power, since it is automatically configured as its connections have been made when receiving
electrical network. In case of making any change it is necessary to deactivate the electrical network, make the change and reconnect to the electrical network.
CONNECTION
To start connecting the 40426 power stage, follow the instructions below.
AUDIO INPUT
You can connect 2 types of input lines (1) detectable manually or automatically.
• EGi PIN audio from EGi modules, with 3 V~ audio signals + activation signals from +4.5 to 7 Vdc, to activate the start of the stage automatically while
incorporating an audio signal of sufficient value to carry Parallel or twisted cable lines.
• LINE audio from sound sources or preamplified modules, with audio signals from 250 mV~ to 750 mV~ without any activation.
POWER ON CONTROL
To activate the manual stage or automatically with pre-amplified signals, you can do it in 2 ways using the following type of connection (2).
• ON/COM - By means of these 2 normally open (NO) contacts, we can activate the stage manually by closing this contact through a closed bridge, relays or normally
open switches (NO), to close them and activate the stage in POWER ON. While the contact is closed the stage will be on (ON).
• AUTO/COM - By means of these 2 normally open contacts (NO), we can activate the stage automatically by closing this contact through a bridge. In this way, the
stage is in a stand-by state but activating the audio detection system to turn on the stage when an audio signal is detected. This detection works and activates
the power stage at the moment that there is a minimum audio signal.
During the time that there is music, the stage will work indefinitely until there are no hollows of silence of more than 30 seconds. After that time the stage will
go into stand-by mode until it detects another audio signal again.
NOTE: There are passages in music of similar intervals, but they are very punctual and not important since the stage will be activated again when there is
audio. It is recommended to take special care in the wiring to be used between the musical source and the stage; since these can induce noises that activate
the stage without audio. To do this, use twisted cable for EGi PIN lines or shielded coaxial lines for LINE IN inputs.

SPEAKERS CONNECTION
To detect the connection mode made, first connect the speakers to the SPEAKER CONNECTION output (7) according to the desired mode, and then feed the stage
with electric current at the power input.
Before making any changes to the speaker connection mode, remember to first remove the mains supply, second modify the speaker connection and finally
reconnect the mains power (DO NOT MAKE CONNECTION CHANGES IN LOUDSPEAKERS WHILE POWER IS EXISTING OF NETWORK).
• CONNECTION IN STEREO MODE (– L + / – R +) - Connecting 2 speaker lines we obtain a stereo connection. One on the left channel (Left) and one on the right
channel (Right). In this way when receiving the electric current, the stage will detect that the operation is stereo mode of 2x25 W and the minimum impedance per
line should not be less than 4 .
• CONNECTION IN MONO BRIDGE MODE ( / ) - Connecting 1 line of speakers in bridge mode, when the electric current is received, the power stage goes
into mono mode adding the L and R inputs, obtaining a single channel in bridge mode of maximum 1x50 W and minimum impedance not less than 2
This connection has the peculiarity of going only in the 2 central sockets of the terminal strip "speaker connections", and the 2 lateral connections of the same
should not be used.
NOTE: To guarantee a correct reproduction of audio and of low frequencies, it is OBLIGATORY to respect the polarities of the speakers and the stage at all
times; both parallel connections and serial connections.
ELECTRIC POWER MAINS
To connect the electrical network, make sure that there is no current in the cables to be connected. Next, unscrew the protection cap (8), release the connection
strip and connect line by line NEUTRAL, PHASE and EARTH (avoid leaving loose filaments). Reconnect the plug-in terminal block to the power section, guide the
cable outlet to the bottom and close it with the protective cover.
STATUS LEDS
The purpose of these LEDs is to inform the installer or user of the state in which the power stage is located.
• STBY (3) - It indicates that there is continuous power supply in the internal power supply and that, if the only LED is on, the stage is in STAND-BY mode.
• POWER ON (4) - Indicates that the stage is activated and turned on during operation; either by PIN input, either by LINE IN AUTO input or by LINE IN ON input.
• MONO BRIDGE 50 W (5) - Indicates that only one line of speakers has been connected in BRIDGE mode in the center of the center sockets of the
"speaker connections" terminal, that the stage has been set to MONO BRIDGE mode.
• PROTECTION (6) - Indicates that during the operation of the stage a protection of the same has been detected; either due to excess temperature, short circuits
in loudspeaker lines, impedances lower than those recommended in loudspeaker lines, derivations of these lines to ground or high harmonic peaks.
