WEEE & RoHS Directives - Sonifex Statement
The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on
13 February 2003, along with the related Directive 2002/95/EC on Restrictions
of the use of certain Hazardous Substances in electrical and electronic
equipment (RoHS).
The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the
impacts of electrical and electronic equipment on the environment during their life times
and when they become waste. It applies to a huge spectrum of products. It encourages
and sets criteria for the collection, treatment, recycling and recovery of waste electrical and
electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive
label placed on the case. It gives a contact for individuals who are unsure about the correct
procedure when the product has reached its “end of use”.
Sonifex Ltd will be happy to give you information about local organisations that can
reprocess the products, or alternatively all products that have reached “end of use”can be
returned to Sonifex and will be reprocessed correctly free of charge.
Sonifex Ltd has phased out the use of certain hazardous substances identied in the
European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS directive
limits the use of certain hazardous substances currently used in EEE manufacture, including
lead, mercury, cadmium, hexavalent chromium, and halide-containing compounds PBB
(polybrominated biphenyl) and PBDE (polybrominated diphenyl ether). Elimination of these
substances will result in more environmentally friendly recycling of electronic equipment.
For the products which Sonifex manufacture, the main area where products were aected
was in the use of lead for manufacturing and assembling electronics circuit boards.
Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the
surface-mount PCB manufacturing processes and for hand soldering. The printed circuit
boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no
lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead
based solder.
The manufacturing processes include the assembly of purchased components from various
sources. Product is oered as RoHS compliant, or LF, only after sucient evidence is received
from the component manufacturers that their components are RoHS compliant. Sonifex
Ltd relies solely on the distributor, or manufacturer, of the components for identication of
RoHS compliance. Thus whilst every eort is made to ensure compliance, Sonifex Ltd makes
no warranty, or certication, or declaration of compliance concerning said components.
Sonifex Ltd denes“Lead Free” as pertaining to any product, which has been manufactured
by Sonifex Ltd using components which have been declared by the manufacturers as
“Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component
manufacturer documentation.

INTRODUCTION
INTRODUCTION 1
Phone In 6 Introduction
The Phone In 6 is a call control centre for phone-in radio
shows. It is capable of interfacing to 2, 4, or 6 phone lines
by tting up to 3 modules, where each module can have
2 x PSTN lines or 1 x ISDN BRI line. The ISDN basic rate
interface allows 2 calls to be handled, 1 on each B channel.
The PSTN module has 2 interfaces each using a modern
digital hybrid interface, which is settable by software to
handle a variety of PSTN and PABX systems with varying
impedances, call connection & disconnection tones.
The unit comprises 2 boxes: The PI-6C 1U rack mounted Base Console (BC) unit which has all
the audio & telephony connections together with the metering and complex controls.
Fig 1-1: PI-6C Base Console Front View.
Secondly, there is the PI-6R Remote Control Panel (RCP) which connects via Ethernet based
cabling to the main unit and allows the user to see the status of each caller, to receive an
incoming call and to subsequently route it to the mixing desk. It also includes connectors
for a headset that enable remote dialling out and the screening of incoming calls.

INTRODUCTION
INTRODUCTION
The Base Console has 3 module positions on the rear panel into which either of the PI-PSTN2
(2 x analogue telephone lines) or PI-ISDN2 (2 x ISDN B channels) modules can be tted. The
Base Console is capable of connecting internal DSP and hybrid circuits to any 2 lines and
routing these out to a studio mixing desk.
The Phone In 6 uses an echo-cancellation DSP (digital signal processing) algorithm and
impedance matching to give around 70dB cancellation, which provides excellent separation
of caller & line send audio and elimination of feedback, distortion & echo on the incoming
calls. This is close to being the best performance possible on a telephone line & uses the
same enhanced echo cancellation algorithms as used on the DHY-03 telephone hybrid,
the best performing telephone hybrid in the world. The DSP, which uses 24bit variables
and at least 48bit math algorithms, can also monitor the call progress tones for various
disconnection arrangements. The audio data is supplied to the DSP from analogue inputs
via 24bit ADCs.

INTRODUCTION
INTRODUCTION
Phone In 6 Operation
The Base Console is connected to the incoming lines; to a music-on-hold source; to 1 or
2 channels on a mixing desk and to the Remote Control Panel. The Base Console accepts
an incoming call and indicates the ring to the Remote Control Panel. The call is either
automatically answered by the unit and supplied with music-on-hold, or is answered
manually by the user. The user has the following options:
- Send the caller to the mixing desk by assigning it to an on-air channel.
- Place the caller on-hold and send them the music-on-hold signal .
- Drop the call.
During the initial call control there is limited processing being performed by the unit, but
once the call is assigned to an on-air channel, the audio is passed through to the DSP to
provide the highest quality possible for the station output.
DSP Features Of The Phone In 6 System
- Echo-cancellation which cleans the telephone signal to remove any echoes from the
analogue portions of the call and ensures that the mixing desk is only sent the caller audio.
- AGC (automatic gain control) & a Noise Gate which sets the level of the caller audio to a
suitable level for the mixing desk and also reduces the noise oor when the caller is silent.
- Ducking so when both caller and presenter are talking together the DSP can automatically
reduce the level of the caller so that the presenter is always able to talk over the caller, e.g. to
gracefully end a heated call;
- In conference mode the DSP mixes the other caller audio into the sent signal so that each
caller can hear the station output and the other caller in the conference call.
Conferencing Calls & Use of the Cleanfeed/Mix-Minus
The Phone In 6 handles 2 live calls at once and normally each call is connected to a separate
telco channel on a mixing desk. Each channel receives the caller audio and allows the
presenter to talk to the caller o-air (usually via the pre fade listen (PFL) or Cue selection on
the mixer), or to place the caller to air. In both cases the mixing desk outputs audio back to
the caller via the Phone In 6 unit – this is usually the signal from the presenter’s microphone
or a special mix of the station output.
The unit is congured in 2 ways:
Normal Mode where 2 calls can be handled independently, each with its own caller output
and cleanfeed input.
Conference Mode where up to 2 calls are mixed within the unit and are presented as a
single audio stream on the output with a single cleanfeed input.
The cleanfeed, also known as mix-minus, is a specic mix from the desk/mixer that contains
all of the radio station output except for the caller himself or herself. In Conference Mode
the unit provides a mix of both callers and the cleanfeed is a mix without either caller. The
unit mixes in the other caller for each signal sent out to the callers.

4Phone In 6 User Handbook
1
INTRODUCTION
INTRODUCTION
In Normal Mode the unit should be connected to 2 telco channels that each generate
their own cleanfeed output. If the mixing desk is able to generate a cleanfeed without
either caller from the 2 independent caller outputs, then the unit can accept a single input
and add in the other caller for the appropriate caller output the same as is performed in
Conference Mode – this is known as Shared Mode.
Call Handling - Self-op & Call Screening Modes
The Phone In 6 allows radio shows to be organised in 2 main ways:
- Self-op where the show is entirely controlled by the presenter.
- Call-screening where an assistant or producer deals with incoming calls manually and then
places the calls to the presenter via the on-air selections.
Self-op Mode
In Self-op Mode the unit can automatically answer calls and place them in a queue where
they are supplied with the music on hold signal. When the presenter is ready, they can
accept the next caller to air. The queuing system can be set to use 1 or 2 hybrid channels,
though if the mixing desk has only one telco module available we advise that you do not
use conferencing and queue to a single channel only. If 2 channels are available and you
congure it to use only 1 hybrid for the queue, then the second channel is available for
manual intervention, for example to save a call when the presenter needs further caller
details as a prize winner, or to make outgoing calls.
Auto-Answer & Auto-Drop Calls
Calls are auto-answered and by designating one of the GPIO remote input ports to receive
a ‘drop call’ command when the channel is switched o, the call is dropped once the
conversation with the presenter has nished. The calls can be shued up so that line 1 is
designated as the on-air 1 caller, then on-air 2, then unanswered calls in their queue order.
Or the ON-AIR 1 and ON-AIR 2 (if used) buttons show the current calls to the mixing desk
and the next call ashes its LINE HOLD button yellow.
Call Screening Mode
In Call-screening Mode an assistant/producer can answer calls and then the caller can be
put on-hold and supplied with the Music On Hold signal until the presenter is ready to take
the call. The call-screener communicates to the presenter by the normal talkback interface
on the mixing desk. The procedure to manually handle calls is described below
Receiving a Call
When the unit receives a call, the LINE HOLD button ashes red for that line. The call handler
should press the button to accept the call, which stops the ashing, illuminating the button
green and routes it to the Music On Hold signal.
If the call handler is ready to talk to the caller straight away, then pressing the LOCAL button
followed by the LINE HOLD button accepts the call, lights both buttons yellow and routes it
to the call handler’s headset. The call can then be put on hold by pressing the LOCAL button
again, which clears the LOCAL button and makes the LINE HOLD button go green.

Phone In 6 User Handbook 5

INTRODUCTION
INTRODUCTION
Routing a Call
To route a call to the mixing desk, press the ON-AIR button associated with that line. The
ON-AIR button illuminates green and the audio to and from the caller is routed through the
DSP hybrid and to/from the mixing desk. The unit can be programmed to send a signal to
the mixing desk from the GPIO port to allow the telco channel on the mixer to indicate that
a call is present.
If the hybrid is already in use, or the unit is in conference mode and 2 calls are already being
handled, then the ON-AIR button ashes red briey and returns to the o state. To remove
a call from the hybrid press & hold the ON-AIR button for a second and the caller is returned
to the Music On Hold state
Dropping a Call
To drop a call, simply press & hold the LINE HOLD button for a second and the call is
dropped.
Making a Call
To make a call press the LOCAL button followed by an unused line’s LINE HOLD button.
The headset is now connected to the line and the call handler should hear the dial tone.
Use the keyboard to direct dial a call using DTMF dialling or use the hash (#) key to use the
phonebook entries or ## to repeat the last used number.
Phone In 6 Conguration
The Phone In 6 comprises 2 units, a Base Console (BC) and a Remote Control Panel (RCP)
communicating through a TCP/IP network. The units each need a TCP/IP address to
communicate and also need to be paired to work together. The conguration is performed
entirely at the RCP where the TCP/IP address is set in static mode or set to use a local DHCP
server. The RCP can then search for base units attached to the system. It may nd a number
of connected BC devices and the serial number and state of each unit’s connectivity is
indicated. Choose the appropriate BC and designate it as the pair for the RCP. This unit can
then also be congured for its TCP/IP address.
The system can then be set up to operate in the manner required using the menu system
on the RCP. Some of the setup is specic to the actual install, e.g. country type for the hybrid
settings, ring cadences & disconnect tones supplied by the network provider. Other settings
can be program specic, e.g. call screening/self-op mode. The latter settings can change
with the presenter, or as a particular show changes, so multiple sets of these parameters
can be saved into permanent memory within the system which the user can easily store and
change by using the * key and a single digit number to update those parameters.
The RCP has the ability to make calls to unused lines and there is a Phonebook that allows
the user to create 99 preset numbers which are easily accessed by using the # key followed
by the 2 digit number. Also a double # key calls the last dialled number.

All of the parameters are accessed via the Remote Control Panel menu options. Simply
press and hold the rotary spinwheel to enter the menus. Use the spinwheel to move along
the menu selections, or to change the value of a parameter and just press the spinwheel to
accept the option. Pressing & holding the spinwheel button exits the menu system.
Figures 1-4 shows the menu options available, but not all options are accessible for each
system (e.g. no ISDN options are displayed for systems supplied without ISDN modules
tted).
The menu is self explanatory, allowing access to all of the possible options available on the
system.

Phone In 6 Base Console Front Panel Controls & Indicators
The Phone In 6 Base Console is a 1U rackmount unit to which the audio & telephone
connections are made & which houses the two digital telephone hybrids.
The level of the caller outputs and mix-minus send are displayed on four 8-digit bargraphs.
Each has 2 associated LEDs for AGC (automatic gain control) and Limiter operation. AGC is
applied to the levels to ensure operation in a normal range, but further xed gain can be
applied by front panel switches. The signal level sent to the telephone line is regulated by
telecom providers and the unit at all times controls the call level to maintain the signals to
their legal limits.
The front panel also has a blue power indicator LED and a recessed reset button.
Fig 3-1: Base Console Front Panel
Meters
The meters indicate the levels for both send & receive signals between
the hybrid and the line. For proper operation the 0dB LED should
be illuminated most of the time that normal audio is present, with
occasional peaks just illuminating the +6dB LED (rst red LED). The
signal is a pseudo-PPM meter which shares the characteristics of
the PPM dynamics, but is tuned for the telephone environment. The
meters are equi-spaced in the working zone (-6 to +9dB) but to extend
the scale for low-level signals the lowest 2 LEDs are spaced on 12dB
intervals. The unit can work in this range if required but the noise
oor may be excessive (due to the nature of telephone lines) and
consequently the performance of the hybrid may be compromised.
Gain Controls
Gain controls are provided for both send & receive levels on each
hybrid and allow adjustment of the audio gain in 6dB steps from 0 to
+12dB. Changes in the gain switches are reected in the meters.
LED Indicators
LED Indicators are provided for both send & receive levels on each
hybrid and show the active state of internal gain controls within
the DSP. When the digital audio build option is selected (i.e. AES/
EBU inputs and outputs), the panel also shows the lock state of the
incoming digital audio signals.
