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.
