1. Introduction

The Quattro2 is a high quality conference phone for use in medium to large conference rooms. It has an
exceptionally large pickup and broadcasting range yet it is small in size. The Quattro2 utilizes multiple
microphones, multiple speakers and a powerful DSP to obtain its performance.

In its basic configuration the Quattro2 is designed for PC VoIP communication utilizing its Primar y Interface. In
addition the Quattro2 can include a Secondary Interface mo dule that will communicate directly with your
telephone line, or other communication links, per your choice. The interface modu le can be replaced by the
factory or by an approved dealer. Please send an e-mail to

[e-mail] or call your dealer for details.

This manual covers instruction for the installation and usage of the Quattro2 in its basic configuration and with
several selected interface modules. Specific instructions for other interface modules may be provided
separately when you purchase a unit with that specific interface.

Interface modules that are detailed in this manual include:

- PSTN interface (POTS telephones)

- VCA (video codec) interface

- Daisy Chain interface

- Digital Telephone interface

2. Key Elements

The Quattro2 utilizes:

- Four microphones

- Four loudspeakers

- A powerful Digital Signal Processor that performs the

unit’s sophisticated audio processing. This processing
includes:

o Detecting a person speaking
o Findi ng the direction of the person speaking relative to the unit
o Aiming a directional audio beam towards the person speaking using our proprietary beamforming

array (note: the Quattro2 can manage multiple people speaking simultaneously)

o Eliminate the surrounding noise
o Eliminate the Acoustic Echo
o Eliminate the Line Echo (when used with PSTN interface)
o Eliminate the room reverberation
o Balance the input pickup level of the different speakers.
o Balance the output signal level and adjusting it to the type of signal being broadcasted.

The Result: Extended pickup and broadcasting range that can provide high quality communi cation
in a large conference room setup.

3. Key Features

- Extended and powerful broadcasting capability: As a result of its unique design the Quattro2
drives up to 25 Watts peak power through its loudspeakers, delivering a strong and clear output
signal. This feature is critical in large room coverage.

- Daisy Chain capability: The user can daisy chain unlimited number of units for extended size room
coverage. Each chained unit will perform independent audio pickup processing and deliver it to the
unit in front of it in the chaining hierarchy. The higher hierarchy unit will select the best availabl e audio
signal to pass on. Each of the chained units will also transmit the output signal (more details in the
Daisy Chain Interface chapter).

- Battery operation: Each of the secondary interface modules includes a built-in rechargeable battery.
The unit does not have to be connected to the power supply for power. The user will be notified when
the battery power is low. The unit can be recharged through the USB or with AC/DC wall mount
power supply (supplied with units with a Secondary interface module).

- Three-Way communication: When using the Quattro2 with both the computer (through the USB
interface) and an additional communication device (through the additional interface module - like the
PSTN line) the Quattro2 mixes the incoming and outgoing signals so that the three partners (the
Quattro2 user, the telephone communication, and the computer communication) are full p articipants
in the conference. In addition to being convenient in many instances, this feature allows recording of
the telephone conferencing and also playback audio files into the tele phone lines.

4. Control and Panels

The Quattro2 has:
A Primary (USB) interface panel

A Simple control panel and

A Secondary interface panel (optional)

Primary (USB - Computer) Interface Panel

The unit has a primary (USB) panel that includes three jacks:

- USB (on the right) for computer communication

- Cascading (DIN6 - in the middle) for chaining additional

Quattro units. This connector is referred to as “Link
Down” connector. The chained unit must have a Daisy Chain interface. Please refer to the Daisy
Chain Interface chapter for more details.

- 3.5mm for external speakers or headphones (using this jack will disable the unit’s internal speakers).
This Jack can also be configured for external microphone. The configuration is done through the
