The mixer amplifi ers of the 3300 range are extremely versatile and suitable for systems
for announcements and background music in bars, restaurants, shops, churches, mosques, factories and so on.
• Protection of the last stage and transformer for constant-voltage lines (connection of
all the speaker units in parallel on two-wire lines).
• Balanced microphone inputs, each with its own volume control, suitable both for
dynamic microphones and for condenser/electret microphones (PHANTOM power
supply).
• Front-panel microphone input (on the rear on model AX3303) with priority circuit on
the other inputs (VOX) and control of the activation threshold.
• Dedicated input for audio connection of a PABX for sending announcements over the
telephone and/or an emergency signal with a higher priority (the background music,
if any, and the other microphone inputs are automatically cut off).
• Additional inputs for music sources with front-panel switches.
• Two-tone warning signal generator (CHIME)
• Output for a recorder and/or cascade connection of another amplifi er.
• Signal of the selected music source always available on the MOH ‘Music On Hold’
power output (1W/8 Ohm) for driving directly a monitor loudspeaker or for sending the
signal to other equipment or to PABX’s (except for model AX3303).
• Independent volume controls, treble and bass control and general volume control (for
models AX3306 and AX3312 only).
• Power output displayed by means of LED-meter set in dBs (except for model
AX3303).
Mixers – Equalisers – Antilarsen
The MX8033 preamplifi er-mixer has a certain number of audio inputs that can be
further expanded, PHANTOM power supplies for electret microphones and - thanks to
the precedence circuit - several levels of microphone priority.
The P8023 single-channel graphic equaliser has 31 adjustment steps in one thirds of an
octave. It is used typically in sound-reinforcement systems for acoustic compensation
of the rooms.
The P8024-B feedback controller is capable of reducing the effects of speaker-to-
microphone acoustic feedback (better known as the Larsen effect), by attenuating the
frequencies at which these effects are initiated.
