The Rocco cabinet is tuned fourth-order Bessel. This unique
topology enhances the bass performance with the room
reinforcement characteristics. It offers a flat and linear
frequency response down to the low 16 Hz. Due to its
performing design, the Rocco does not need any active
frequency equalization. It’s a purist design capable of high
dynamic impacts, very low distortion and high reliability.
The Rocco amplifier is based on modern digital amplification
— providing a transparent and musical path to the original
performance. It presents a naturally extended sound quality
that transcends older amplifier technologies in both efficiency
and sonic quality.
The combination of low output impedance and a massive
multi-wave rectified power supply provides stable power under
the most demanding and dynamic conditions.
Advanced overload management and circuitry protection
eliminate system worries, allowing maximum performance on
demand.
It is a fully balanced differential amplifier reducing low
frequency power supply noise and increasing common mode
rejection, to improve the signal-to-noise ratio.
Sophisticated dual-zone star grounding and a double-sided
ground plane fill combined with ground bounce correction to
maintain the quietest system reference possible.
The Rocco 500 VA transformer at maximum power is at the
core of the power supply. Combined with amplifier technology
that is 90% efficient, it provides a power supply that exceeds
demand, maintaining a constant and cool temperature.
The Rocco amplification delivers a remarkable 700 watts of
short-term continuous power to the two 12-inch woofers.
Also, nothing has been neglected in the active processing
stages. The Rocco is equipped with high-quality RCA and XLR
connectors, high precision controls, precise electronic
components and a high-performance dynamic processor that
give state-of-the-art protection. It makes the Rocco extremely
reliable under the most demanding conditions.
The Rocco accepts RCA or balanced inputs. It can be true or
inversed polarity. It offers lowpass slopes of 12 to 24 dB per
octave. The lowpass frequencies can be selected from 30, 35,
40, 45, 50, 56, 63, 71, 80 Hz and 250 Hz when “Movie” is
selected. The “Movie” position bypasses the lowpass filter. The
amplitude level control can offer a +6dB gain to compensate
for main speakers amplifier gain. “LFE” input is provided for
home-theater applications. “Left” and “Right” inputs are
provided for stereo applications. If both should be used
together, they are down-mixed mono.
Connection
Setting-up typical subwoofer can be laborious. But the Rocco
is designed to be easy to install. Before connecting and setting-
up your Rocco, review the layout diagram located at the end
of this manual. It will further guide you in properly connecting
and configuring your Rocco subwoofer.
TWO-CHANNEL SYSTEM
How to Connect One Rocco
1. Connect your preamplifier left output to the left subwoofer
input;
2. Connect your preamplifier right output to the right
subwoofer input;
3. Adjust the Rocco RCA/XLR control to the selected input.
How to Connect Two Roccos
1. Connect your preamplifier left output to your left
subwoofer left input;
2. Connect your preamplifier right output to the right
subwoofer right input;
3. Adjust the Roccos RCA/XLR control to the selected input.
MULTICHANNEL OR HOME-THEATER SYSTEMS
How to Connect One Rocco
1. Connect your preamplifier/processor LFE output to the LFE
subwoofer input;
2. Adjust the Rocco RCA/XLR control to the selected input.
How to Connect Two Roccos
1. When two LFE outputs are available:
a.
Connect your preamplifier/processor left LFE output
to your left subwoofer LFE input;
b. Connect your preamplifier/processor right LFE output
to your right subwoofer LFE input;
2. When only one LFE output is available, connect your
preamplifier/processor LFE output to your two subwoofer
LFE inputs;
3. Adjust the Roccos RCA/XLR control to the selected input.
Turn off your Rocco subwoofer before
making any signal connection!
Connecting the left and right channel to the same unit will
down-mix the input left and right signals to mono.
