Swift Digital transmitter options
The SwiftTX pendant transmitter is exceptionally light and easy to wear and has excellent
sound pickup.
The handheld transmitter is ideal for group discussion or guest use.
The Swift Digital can have two transmitters in use simultaneously in addition to accepting
audio input from a SwiftConnect and any directly connected aduio input.
Components & Installation
Your Swift Digital kit will include one or more of the following:
Handheld microphone
transmitter
Optional
SwiftConnect wireless link
Swift TX microphone

The Swift Digital is a wireless infra-red soundfield system which benefits
both students and tutor ‒ a few minutes of your time will help you
understand how and why the system works so well.
A soundfield system...
benefits the tutor
offering greatly reduced
vocal fatigue, improved
class discipline and
attentiveness.
Less repetition is required
and there is a generally
less stressed teaching day.
benefits the student
offering improved speech clarity and verbal recognition for all
class members including those with permanent or temporary
hearing loss. Academic performance has been shown to
improve with the introduction of a soundfield system.
A relaxed listening experience
Try the system out with a colleague before using it in class. When setting the volume, if you
can hear your own voice very clearly from the Swift Digital unit from across the classroom
then the volume is probably too loud! Make sure you experience the system by listening to
somebody else. Listening for yourself is the best way to understand why the Swift Digital
system does not need to be set very loud to achieve an enhanced and relaxing listening
experience.
Siting the Swift Digital
The Swift Digital unit is usually best positioned at the opposite end of the classroom to the
tutor, above seated head height. Although the Swift Digital has a single hyper-wide
dispersion speaker, when in use the system actually has two ‘speakers’. One is the Swift
Digital and the other is yourself ‒ a sound source at both ends of the room.
When set up properly, a soundfield system will actually reduce the overall noise level in a
classroom and because there is no need to ‘talk loudly’ it gives a pervasive, clearer & more
natural sound to your voice.
Swift Digital remote volume adjust
The Swift Digital has a remote volume adjust feature for use with a Swift TX transmitter.

Positioning the Swift Digital speaker amplifier
Connevans advise positioning an Swift Digital amplifier/speaker centrally on the wall at the
opposite end of the room to where the tutor would normally stand.
The Swift Digital should be
positioned above head height,
which for a classroom would be
seated head height.
It is difficult to give an exact
measurement as you need to
consider what is already on the
wall, but the criteria are:
a) Above head height so that
there is a direct line of sound
to everybody in the room.
b) Above head height so that
there is line of sight for the
infra-red signal from the
transmitter.
c) The controls should be within
reach for the tutor ‒ although
once set they should rarely
need adjusting.
When using an Swift Digital with the optional shelf stand it may
be sited anywhere where you are happy with its performance
with regard to the sound and signal pickup from the
transmitter ‒ siting it higher is better than lower.
The guidelines above, for wall mounting, still apply.
If placing on a wooden shelf, there are screw holes in the stand base to
allow fixing to the shelf.
There are six controls on the
Swift Digital amplifier. Once set,
these controls are normally left
alone and should rarely need
adjusting. The Swift Digital has
a remote volume adjust feature
when used with a SwiftTX
transmitter.
Included in the Swift Digital kit is
a 3.5mm to 3.5mm stereo lead
(part.no. MXA117A) . If you are not
using a SwiftConnect, this lead
can be used to input sound to
the Swift Digital from an iPod or
anything else with a 3.5mm
headphone socket.
A host of alternative audio leads
including extension leads are
available ‒ please see catalogue
section 10 or our website:
www.DeafEquipment.co.uk
and search ‘audio leads’
The Swift Digital is supplied as standard with a flush wall mounting bracket.
The Swift Digital accepts a standard 100mm VESA mount and a choice of alternate wall
mountings is available, as is a shelf stand.
To conserve power, when not in use, please
switch off at the power socket.
The Swift Digital automatically enters a low
power standby state when not in use and the
blue LED in the front panel blinks slowly
(normally solid). However, as the Swift Digital
operates from an external power supply, on
environmental grounds it is still best to switch
off at the power socket when not in use.

Swift Digital
Mains connection and power supply
It is important that the Swift Digital is sited in a position for good sound rather than just
near to an existing mains power socket.
Ideally there should be a dedicated mains socket near to the Swift Digital amplifier/speaker
unit.
Alternatively, if a mains socket cannot be
fitted close by, the power supply holder may
be removed from the Swift Digital and fitted
directly to the wall.
The power supply holder
may be fitted to the wall either
vertically or horizontally, as
appropriate, and the wire should
be either clipped to the wall or
fitted in trunking.
It is important that both the low
voltage and mains voltage cabling
are safely and neatly secured. We
would advise against fitting the
mains power supply unit and
holder anywhere where it could be
accidentally kicked, or knocked by a
vacuum cleaner.
mains ‒1.8m

To charge a transmitter:
1. Switch off the transmitter and then plug in the charge lead.
2. Plug the charger into a mains socket and turn on the power.
When charging the SwiftTX transmitter, the red charge indicator will light. A handheld
transmitter has no charging indicator.
The charge time from flat for the SwiftTX transmitter is 10 hours and the other transmitters
16-20 hours. It is safe to leave on charge for up to 5 days.
Please note that it may take a few charge/discharge cycles before full capacity is available.
Transmitter battery charging
The batteries in all of these transmitters will last approximately 8 hours.
It is necessary to charge batteries before first use. For the SwiftTX transmitter, fit the supplied
battery (see page 11) and connect to charger. The initial charge should take about 20 hours,
thereafter charge overnight as required.
You will usually need to leave the unit recharging at the end of the day.
To conserve power always remember to switch the transmitter off when not in use.
If a second transmitter is only occasionally used it will need charging less often!

Demonstrate and set the volume level for the room
It is important that the soundfield is set up properly. We have found
that some users set the system too loud. This is unnecessary and
undesirable. The golden rule is "if the user of the transmitter can
hear themselves very clearly from the Swift Digital, then the volume
is probably too loud". It is difficult for the person talking to judge
the level of their own amplified voice.
The usual way to set up an Swift Digital uses the subjective
judgement of another person. Two people are required with the class
tutor preferably being the one doing the talking.
Setting the correct volume level
l Wear the microphone as shown.
l Stand at the front (your usual position).
l Switch the transmitter off and talk in a normal voice to your colleague
while they stand at arm’s length in front of you.
l Ask your colleague to remember the average sound level and
then get them to walk over to the Swift Digital amplifier/speaker.
l Switch the transmitter on.
l Ask your colleague to increase the 'Mic A' volume control on the
amplifier, whilst you continue to talk in the same normal voice as
before, until they judge the sound level at arms
length from the Swift Digital to be just slightly louder
than when they were standing in front of you.
l The tone controls can now be adjusted if necessary
to optimise vocal clarity.
l Ask your colleague to make sure that your voice is
clear all around the room.
Job done! Don't be tempted to increase the volume
much further as teachers tend to raise their voices in an
active classroom situation!
Confidence
Please do not underestimate the importance of ensuring that the tutor has the opportunity to
experience listening to another person using the Swift Digital. There are two reasons for this:
firstly so that they become impressed at the natural sound and secondly it is hard for anyone
to listen objectively to their own voice. It is also an excellent opportunity to ‘play’ at using the
system with a colleague, allowing the tutor to gain confidence with their own ‘performance’.
If the system is to be used with a second microphone you must now go through the same
procedure using the ‘Mic B’ volume control.

Changing the rechargeable battery
The rechargeable battery will only need changing very
occasionally ‒ it should last between 1-2 years.
To open battery compartment, press in the centre of the battery
door with both thumbs and slide off.
The battery door is treated with a clear
anti-slip finish to reduce the tendency to
move when worn.
Pull on ribbon tab to release battery.
Use
only with the exposed metal end
battery as supplied with the Swift TX.
Other types of battery will not charge.
Rechargeable battery:
1 x 2800mAh high capacity rechargeable
AA battery ‒ exposed end
(MBRAAHX1) .
This battery is fitted with the exposed metal end against the spring.
Position the battery on top of the ribbon tab for easy removal
next time.
Technical Note ‒ when a battery is first inserted, the SwiftTX will
automatically test the battery to make sure it has enough charge.
The indicator will show orange for 5 secs while it is testing, followed by green or red for 1 sec:
Green ‒
the battery has enough charge. Red ‒ the battery needs to be recharged .
A flickering indicator or no indicator ‒ the battery has no charge and needs to be recharged
or replaced.
Using the SwiftTX on external power
Connecting a charger automatically turns off the SwiftTX and starts charging it (red
indicator). During charging, a press of the ON/OFF button will suspend charging and return
the unit to ON (green indicator) ‒ in this mode, although the battery needs to be fitted, the
SwiftTX is now powered from the charger rather than the battery.
Using external power will preserve battery life when connected to an external sound source.

SwiftTX pendant microphone transmitter
Indicator LED
The indicator LED shows green, red or orange, depending on the status or mode of the Swift TX.
In normal use:
Solid green ‒
the SwiftTX is on and
working.
Alternating green/red ‒ the battery is
low and the unit needs to be recharged.
No indication ‒ the unit is switched off.
When charging:
Solid red ‒ the SwiftTX is charging normally and
is turned off.
Flashing red ‒ there is a problem with
charging ‒ refer to fault finding appendix D.
Solid orange ‒ the SwiftTX is fully charged and
the charger has switched to trickle charge.
The two parts of the neck clasp
may be pushed together or
pulled apart either directly or
by sliding.
Adjusting the neck strap
Correct positioning of a pendant transmitter is important. The SwiftTX
pendant should be worn so that the emitter faces forwards and the unit
rests about 150mm (the length of a biro) below the mouth ‒ this means it
should sit just below your collarbone.
Both straps can be easily adjusted as required, using the sliders.
Note ‒ replacement straps are available, please see Appendix B.
To turn on the SwiftTX press and hold the on button until the status indicator lights. Similarly
to turn off or mute the SwiftTX press and hold the button until the indicator goes out.

Remote volume control feature ‒ for use with Swift Digital
When used with a Swift Digital speaker amplifier, the SwiftTX can be
used to remotely adjust the channel volume.
The blue LED in the front panel of the Swift Digital receiver/amplifier
flashes rapidly when receiving a valid remote control signal from
the SwiftTX.
The range of remote volume adjust is +/- 15dB and allows the user
to temporarily adjust the volume of their voice from the Swift Digital.
A short press of the + or - button on the top of the transmitter will
increase or decrease the current volume by 1.5dB.
Holding down the + or - button will change the volume at the
rate of 6dB per second.
To reset the volume to the default manual setting on the
Swift Digital unit, press both the + and - buttons simultaneously.
The Swift Digital volume will reset itself to the manual setting when
the Swift Digital speaker amplifier is in standby or turned off.
Swif t Digital
Note ‒ the remote volume control function will only
work with the IR Swift+ and new Swift Digital models.
Volume up
Volume down
Volume reset
The SwiftTX is normally used on channel A. However it can be easily changed to channel B
as follows:
Open the battery compartment.
Inside, just above the battery, you will be
able to see a small switch labelled ‘A
channel B’.
Use the end of a paperclip or a small
screwdriver to slide the channel switch.
Always replace the battery compartment
cover afterwards.
Channel change
The Swift Digital unit has two mic receiving channels A & B. The SwiftTX A/B channel change
switch is in the battery compartment.
Pendant, beltpack or handheld transmitters can be used on either channel.
Connecting to external sound sources
The SwiftTX transmitter has a 3.5mm stereo
auxiliary input socket to rebroadcast sound
from external sources such as laptops or iPods.
Microphone
Dual directional microphones
The SwiftTX uses two separated microphones (Left and Right) to provide a constant
transmitted voice level as the user’s head is turned from side to side.
The optimised dual microphone design also provides ideal pick up of the user’s voice and
rejects unwanted sounds in all other directions.
This means that you don’t get a variation of volume
as the speaker moves their head from side to side.

Handheld microphone transmitter
Charging the handheld transmitter
Depending on use, the handheld mic may only need charging every 1-2 weeks
(approx. 8 hours use).
Remember to switch off the handheld mic before charging.
Use the external charger 45IRTXHCHG2 plugged into a mains socket.
Charge time is 16-20 hours from flat
(i.e. overnight), please disconnect charger
after 20 hours ‒ no automatic charge cycle.
Channel change
Most users will never need to change the channel of the handheld microphone. If one
SwiftTX and one handheld mic are being used, there will be no need to change channels.
More than one pendant or handheld microphone transmitter can be used on either channel
for team teaching as long as only one is switched on at any one time.
To use two of the same type of microphone simultaneously,
then one will need to have its channel changed.
The handheld transmitter is normally used on channel B.
However, if required, it can be changed to channel A as follows:
Remove the cover of the microphone and the switches will be
easy to see just above the battery compartment.
Use a paperclip or a small screwdriver to slide the channel
switch between channel A and channel B as required.
Please note that the label fitted to the outside of the
battery compartment indicates the switch positions as
‘CH1’ (= Channel A) and ‘CH2’ (= Channel B).

The SwiftConnect can be used in several different ways ‒ the following pages
show you 4 typical scenarios
Power
The SwiftConnect can either be powered from the supplied USB mains power supply or from
a USB output on a computer.
Please note that non low earth leakage USB power supplies
may cause a hum.
When USB power is applied the SwiftConnect will turn itself on, alternatively when you start
using a paired Swift Digital the SwiftConnect will also turn on within 10 secs.
The SwiftConnect automatically enters a low power standby mode 2 hours after it was last
used but will turn itself on again when sound is detected.
Pairing ‒ if the SwiftConnect has not been used with the Swift Digital previously, please see
bottom of page 21.
