1. Introduction
The Quattro is a high quality speakerphone for use in medium to large conference rooms. It has
an exceptionally large pickup and broadcasting range yet it is small in size. The Quattro utilizes
multiple microphones, multiple speakers and a powerful DSP to obtain its performance.
In its basic configuration the Quattro is designed for PC VoIP communication. In addition the
Quattro may include an interface module that will communicate directly with your telephone line
or other communication devices, per your choice. The Interface module can be replaced by the
factory or by an approved dealer. Please send an e-mail to
support@phnxaudio.com or call your
dealer for details.
This manual covers instruction for the installation and usage of the Quattro in its basic
configuration and with several selected interface modules. Specific instructions for other interface
modules will 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 and analog) interface
- Daisy Chain interface

2. Key Elements
The Quattro utilizes:
- Four microphones
- Four loudspeakers
- A powerful Digital Signal Processor that
performs the Quattro’s sophisticated audio
processing. This processing includes:
o Detecting a person speaking
o Finding the direction of the person
speaking relative to the Quattro
o Aiming a directional audio beam towards the person speaking (note: the Quattro
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
communication in a large conference room setup.

3. Key Features
-
Extended and powerful broadcasting capability:
As a result of its unique design
the Quattro 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.
-
Ganging capability:
The user can gang unlimited number of units for extended size
room coverage. Each ganged 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 available audio signal to pass on. Each of the ganged units will also
transmit the output signal (more details in the Daisy Chain Interface chapter).
-
Battery operation:
Each of the 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 the interface m odule).
-
Three-Way communication:
When using the Quattro with both the computer
(through the USB interface) and an additional communication device (through the
additional interface module - like the PSTN line) the Quattro mixes the incoming and
outgoing signals so that the three partners (the Quattro user, the telephone
communication and the computer communication) are full participa nts in the conference.

In addition to being convenient in many instances, this feature allows to record the
telephone conferencing and also playback audio files into the telephone lin es.
