Montarbo Nm250A Loudspeaker

Description

Montarbo Nm250A Speaker Cabinet

2 MosFet AB class amplifiers, each controlled by a sophisticated active transducer protection circuit and a 'soft-start' circuit to reduce current peaks on power-up.

The two amplifiers deliver an output power of 250 Watts, divided into 200 Watts for low frequencies and 50 Watts for high frequencies.

2 dedicated dynamic processors, which optimize the system's response curve, adapting the signal to working conditions, and directly control the characteristics of the components.

These processors work with independent time constants and intervention thresholds sensitive to the power supply voltage, preventing excessive excursion of the voice coils and thus ensuring correct operation even in the presence of strong power supply fluctuations.

an active electronic crossover (24dB/oct) that ensures phase alignment and perfect overlapping of woofer and mid/high emission in the crossover region.

A 2-band equalizer allows the system's response curve to be varied, thus achieving optimal performance based on different usage requirements, increasing its versatility.

The control and connection panel of the NM250A system features:

a balanced input on a Neutrik Combo socket (XLR+Jack), switchable mic/line by means of a specific selector (allowing it to be used as a standalone amplification system);

a balanced output (link) on an XLR socket for parallel connection of multiple systems;

2-band equalization.

Allows optimizing the speaker's behavior for a conference room, for monitoring within a music ensemble, or for other uses;

volume control.
