FEATURES
Microprocessor
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.
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.
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.

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).

EnglishEnglishEnglish
user manualuser manual
10
Also featured is a circuit that controls the temperature of the toroidal transformer and
protects this against even the most exasperated operating conditions. If this cutout trips,
then the equipment is being used at the limits of its characteristics.
Such tripping is indicated by the fast flashing of the "STATUS" indicator light and by the
"mute" status audio signal (see diagnostics table).
All functions restart automatically when normal operating temperature is achieved.
Restart times can be fairly long, especially when the thermal cutout of the transformer
trips because the core takes a long time to dissipate the accumulated heat.
CC/DC/RFI
The amplifier features a short-circuit cutout for each output. This cutout places the output
signal of the stage involved in "mute".
The amplifier features relays on the audio outputs. These devices protect the speakers in
case of direct current, radio disturbances, subsonic frequencies and have an anti-bump
function at amplifier switch-on.
Tripping of these cutouts is indicated by the "POWER" indicator light going off and by the
different flashing sequences of the "STATUS" indicator light (see diagnostics table).
The amplifier will start operating normally again when the cutout condition is eliminated.
Power voltage
The amplifier features a circuit that ensures correct speaker operation in case the mains
power voltage is too high.
If the power voltage exceeds a max pre-established value (+15%) for a short time (power
peak), the fault will be indicated by means of the "POWER" indicator light, which will flash
quickly for about 10 seconds (see diagnostics table).
If the power voltage stabilizes at high levels, the amplifier will become disabled.
If the power voltage drops below the minimum established value (about -20%), the fault
will be indicated by means of the "POWER" indicator light which will start flashing slowly
(see diagnostics table).
This function is also useful in case of inadequate power supply wiring.

The “XLR” connectors connected in parallel with the inputs (6) can be used to send
input audio signals to other amplified speakers.
8) ”BALANCED XOVER OUTPUTS” OUTPUT CONNECTOR (LEFT - RIGHT)
Internal crossover balanced outputs.
These signals must be sent to other OPERA type amplified speakers.
The crossover frequency can be selected by means of the “XOVER SET” switch (9).
9) “XOVER SET” CROSSOVER FREQUENCY SWITCH
This 3-position switch permits selecting the crossover frequency between the
subwoofer and the speakers connected to the XOVER outputs. Choice depends on
the type of speaker used for reproduction of mid-high frequencies.
For speakers with 12” cones, it is best to use 100Hz or 120Hz, while with 15”
speakers, 80Hz or 100Hz.
10) “SUB LEVEL” VOLUME CONTROL
This control regulates only the volume of the subwoofer. The double indication 0dB
