Description
The AX-309 amplifier
The most innovative features of this unit are:
- Controlled power-up
- Automatic and manual adjustment of load impedance.
- General volume control (master), treble and bass via the keyboard, and which may be
memorised.
- Protection from keyboard tampering
- Forced horizontal air flow system controlled by thermostat at 65 C
AX-309 WX-3
- Display the different statuses of the unit

Mode 1(standard).
Mode 2 (programmed).
includes inside a microprocessor that digitally controls and supervises the main
functions of the apparatus. This particularity, along with the universal signal input system, which can be
configured by the engineer installing the system, make for a reliable, versatile and easy-to use device.
Its mechanical and electronic design are based on the criteria of functionality, toughness and reliability
required in any professional sound application. Its standard sizes (standard 19", 3 U) allow it to be linked
to other elements in the range or others, such as music sources, etc…. making up a homogeneous
compact unit with reasonable space-saving. Its surround housing is protected by a special anticorrosive
treatment.
The system limits the power peak absorbed from AC mains which takes place when the amplifier is
powered up. In this way it prevents damage and other trouble, such as the activation of automatic
protection switches or the blowing of fuses in the electrical panel, which are typical in other high-power
units.
The installing engineer may access the load impedance menu and make the adjustments automatically
or else select the right value manually in each case: 4 , 8 , 70 V line (16 ) or 100 V line (33 ).
This function is highly useful, since it makes it possible to record in the non-volatile memory any
adjustments made for different utilisation conditions, thereby optimising the public address system in
applications in fluctuating acoustic conditions. This is mainly due to variations in the size of the audience,
different speakers, background noise in the area, etc.
This function allows the user to select the adjustments later, simply by pressing a button on the
keyboard.
Volume can be increased slowly or reduced quickly.
The installing engineer may program a password to access the installer menu to prevent unwanted
adjustments.
This makes it possible to mount the amplifier on a rack using accessory , with maximum
space optimization.
Luminous display for adjustments, programming, general volume levels, treble, bass and messages.
The amplifier can operate in two different modes, as per option.
The user can modify the general volume, treble and bass of the amplifier at will.
The user cannot modify the general volume, treble and bass of the amplifier set
in the installation process.
In this mode the user can select each one of the 8 programmes that are preadjusted in the installation
process

Warning messages
SIGNAL
SATURATION
POWER SUPPLY
SIGNAL SATURATION:
POWER SUPPLY:
-A.
-B.
Occasionally, when the amplifier is operating normally, the display may show a flashing
message
This means that the signal that reaches the mixer is excessive in one or several of the 6
inputs. Although the amplifier has a limiter to avoid unwanted distortion, it is a good idea to
readjust the independent volume control of each input where the excess level is occurring
and readjust the general volume, if necessary.
If the amplifier stops working and shows the message, this means that the internal
control device has switched off the unit’s power supply. This may be due to two reasons:
The internal temperature of the unit is too high and the heat protector has been
triggered.
The microprocessor has detected some kind of anomaly in the power supply of the
power circuit, and has switched it off.
Thus, if the message appears, check whether the passage of air (front and rear) is
blocked and put the problem right.
Switch off the amplifier, allow it to cool and then switch it back on again.
Otherwise switch off the unit and call technical assistance.
