How to Configure with Small or Large Loudspeakers
1. For large loudspeakers, adjust the crossover frequency to

35 Hz;

2. For small loudspeakers, adjust the crossover frequency to

50 Hz;

3. Adjust the phase selector to 0 degrees;
4. Adjust the crossover slope to 12 dB/oct;
5. Adjust the amplitude control to the twelve-o’clock


6. While playing music, adjust the volume control until you

get a well-balanced ample and deep bass. Be very careful
not to increase the bass level too much, as it will be very
detrimental to the overall sound performance;

7. Play with the phase selector to get the best loudness.

Readjust the volume control as needed;

Even though we normally recommend adjusting the crossover
slope to 12dB/oct, you can still adjust the slope to 24dB/oct.
You will have to experiment to find out which one is best
suited for your loudspeakers. Larger loudspeakers may give
better results with the crossover frequency adjusted lower than
35 Hz.

To better match your Rocco sensitivity with your main speaker
sensitivity you will need a standard level meter and a white
noise generator. Many audiophile record companies offer a
test CD that includes a track with white noise reproduction.
Play white noise and adjust for the same sensitivity at the
listening position. Compare your two main speakers with all
your Rocco(s). If you don’t have any level meter, simply do it
by ear.

Should you use your Rocco in a home-theater system, the
above adjustments could be done by following the instructions
included in your processor manual. Most processors come with
an automatic level adjustment feature.


How to Configure with Small or Large Loudspeakers
1. For large loudspeakers, setup the preamplifier/processor

to large loudspeakers;

2. For small loudspeakers, setup the preamplifier/processor

to small loudspeakers;

3. Adjust the crossover frequency to the “Movie” position;
4. Adjust the phase selector to 0 degrees;
5. Adjust the crossover slope to 24 dB/oct;
6. Adjust the amplitude control to the twelve-o’clock


7. Follow the instructions indicated in your

preamplifier/processor user guide to complete your setup.
You will have to calibrate your main, surround and
subwoofer(s) for proper delays, levels and speaker-size
within your preamplifier/processor setup;

AC Power Connection

The power cord should be firmly plugged to the Rocco power
receptacle and plugged to an electrical outlet that has the
specified voltage and frequency. The power switch located at
the bottom left of the control module is wired to the AC main
and commute the power going to the Rocco.

Your Rocco should be configured to comply with your country
frequency and voltage. Should they be different, do not
connect the Rocco and refer immediately to an authorized
technician for service.

The frequency and voltage ratings are specified both on your
packaging and near your Rocco electrical inlet.

Should you move to another country, ask an authorized
technician for frequency and voltage compliance. Connecting
to improper frequency or voltage may cause permanent
damage or result in a risk of fire or electric shock.

Replacing the Fuse

Turn off your Rocco and unplug the power cord. Replace with
a specified fuse as indicated on the Rocco control plate. For
220-240 VAC use 2.5 amperes, slow-blow and for 100-120
VAC use 5 amperes, slow-blow.


Your Rocco requires approximately 75 hours of break-in time
before reaching 63% of its full performance. 500 hours will be
required to reach 99%.

Room Placement

A proper room installation of your Rocco subwoofer(s) may
significantly enhance the overall performance of your system.
Even though, some companies propose products that self-
balance their frequency response, there is no replacement for
proper room placement.

Your Rocco is equipped with two 12-inch drivers located on
each side, and a control panel and vent located at the rear.
Knowing that a subwoofer generally gives more output when
located near a room corner and less output when moved closer
to the room center, position your Rocco with the vent facing a
room corner. Leave a minimum distance of 18 inches. None of

The power cord should not be plugged or

unplugged from the unit when associated

accessories are still powered.
