DESCRIPTION

The OPERA SUB 15 speaker features an 15" woofer with an amplifier able to deliver

800W (RMS).

The subwoofer speaker is made using "BAND PASS" so high sound pressures can be

achieved in compact dimensions. Being made of poplar wood, weight is reduced and

handling is easier.

The OPERA SUB 15 diffuser is an active sub-woofer that has been designed to function in

stereo (fig. 1) and in mono (fig. 2) modes.

This sub-woofer is ideal for sounding medium-sized rooms using a pair of diffusers from the

OPERA (212-215) connected in stereo mode or for installations requiring greater sound

pressure, such as those in the open-air, two OPERA SUB 15 diffusers should be used

together with two OPERA (412- 415) diffusers connected in mono mode.

Esempio : 2 x OPERA 212/215

FEATURES

Microprocessor

The OPERA SUB 15 amplifier features a processor for managing and controlling the light

indicators (POWER, STATUS, SIGNAL) and the control/protection circuits to ensure

correct system operation.

Cooling

Amplifier cooling is ensured by a fan controlled by a circuit that automatically regulates

speed in relation to any increase in temperature inside the amplifier.

The four speeds, including stand-by, optimize cooling and ensure reduced forced cooling

noise levels.

For best speaker use, always make sure the amplifier is properly ventilated and never

block the ventilation grilles.

CUTOUTS

Thermal cutouts

Thermal cutouts trip whenever the temperature inside the amplifier overheats

(temperature >90°).

Such tripping of the thermal cutouts is indicated by the slow flashing of the "STATUS"

indicator light and by a "mute" status audio signal (see diagnostics table).
