AX3506 60 W RMS


AX3512 120 W RMS


Models AX3506 (output 60 W) and AX3512 (120 W) have excellent functional features and stand out for their exceptionally good price/performance ratios. The wide range of possible configurations makes each of them a versatile unit able to meet the needs of any small or medium-sized system. Three balanced microphone inputs with phantom power supplies plus an input for B711-G microphone bases. There are two auxiliary inputs for sources of sound (Tape, CD) that can be selected by means of the front-panel control. On the rear terminal block there is an audio input with automatic activation of precedence (VOX); the level and activation threshold can be adjusted via the rear panel. This input can be used for connecting the appropriate audio output of a telephone switchboard.
The precedence contact can be used to activate priority of the microphones over the auxiliary sources, sending a warning signal (chime) at the same time. A VU-meter on the front panel indicates clearly the power being output and any overloads. Each amplifier has electronic protection against short circuits on the loudspeaker line. These units can be mounted on a standard 19” rack using the specific AC3500 brackets.
