Audio output connection
There are two audio outputs on the back of the U-Series SDR5716 Receiver, a Mic-level
balanced XLR-M and Line-level unbalanced 6.35mm jack. We have supplied you with a
balanced cable that goes from the X
LR output into a TRS 6.35mm jack plug as used on
the Fitness Audio Aeromix 2+2 and HRX-32 Mixers.

cable connection will deliver the highest sound quality possible from any microphone,
with more “body” in the voice being the main audible dierence. This audio connection

However, if your mixer has an XLR input socket, then it’s best to purchase a balanced
XLR-F to XLR-M cable to connect the receiver to the Mic Input. Some mixers will also ac-
cept an unbalanced jack to jack lead mic connection with the receiver’s output volume
control adjusted down to suit as an alternative connection, but a balanced cable con-
nection is the better one to use.
Rack Mounting the Receiver
The Fitness Audio SDR5716 Receiver is a 19” half-rack mount design and is supplied
with a specially designed 19” rack mount adapter so can be bolted into equipment
cabinets. Assemble as shown in Fig 3. We have also supplied you with a pair of antenna
extension cables so that the two antennas can be mounted into the holes on the rack
ears out front in the air and not trapped inside a steel box.

Wireless Microphone System Operating Manual
A double receiver rack mount kit is available as an optional extra if required (Fig. 4).
Positioning the Receiver
For best operation, the receiver should be at least 1m above the ground and at least 1m
away from a wall or metal surface to minimize RF reections.
4. THE BELT-PACK TRANSMITTER (SM716)
Channel Selection and Gain
The channel selector and gain adjustment are located under the battery cover as
shown in the picture below. To make channel selection remove the cover and select a
channel by turning the Channel Selector(6) with a small screwdriver. Gain adjustment
for Lavalier and Headset microphones can be done by adjusting the MT trimpot(5),
whereas GT trimpot(4) is for the gain adjustment of an Electric Guitar or other high
impedance line level inputs. If you’re using the Transmitter with an Aeromic then turn
down the MT trimpot to minimum. If
VTJOHBO&t.JDPS7t.JDUIFOMFBWFUIF
MT trimpot at full and turn down only if
distortion is evident.
Due to minor variations in the casing sizes
of many brands of 9V batteries, the trans-
mitter battery compartment is designed
to accommodate the preferred 9V size
battery made by Eveready - the Energizer
9V Alkaline – but other brands may also
work well. Re -chargeable Ni MH batteries
@ 170-190mAH ratings may need to be
re-charged after about 1.5 – 2.0 hours of
continuous use, whereas Alkaline 9V Bat-
teries will generally be suitable for about
6 – 8 hours of airtime with the Aeromic or

A range of transmitter Pouchbelts in dierent styles and colours which can be worn un-
der or over your clothes are available for many dierent users, including tness instruc-
tors, actors, musicians and professional presenters. For more details please consult your
FA System supplier or visit our website: http://www.tnessaudio.com.au/
Pouchbelts shown L - R: Standard, Hipster, Zipster, Grey Zipster, Beige Theater belt.
5. MINI TRANSMITTER (MT-U8)
If your system has been supplied with a Mini Trans-
mitter then it will already be wired to an Aeromic or
$ZDMFNJD&t.JDPS7t.JDFJUIFSBUUBDIFEUPUIFGSBNF
or with an Arm Pouch or Waist Pouchbelt to suit.
To select the matching channel to the Receiver
rst remove the battery cover and with the small
screwdriver supplied change the channel to match
the one shown on the LED screen. Please note
that the MT-U8 is an 8 channel transmitter and will
normally be supplied lining up with channels 01-08
on the receiver, in some countries a “B” group of
channels may also be available (Ch. 09-16). In both
cases the channels line up with the same number
on the receiver and then repeat so that channel 00 is
also channel 08. If you wish to use multiple MT-U8/
SM716 systems under the one roof then at least 4
channels are ne to use without interference from
each other, in the case of the 630-650MHz range it
is channels 1,4, 5 or 8 and of course, if you are also
using a beltpack transmitter in the same or another
room nearby, then it can be set to a channel in the
09-16 group of which channels 10, 12,14 or 16 will
work best with channels 1,4, 5 or 8.

Wireless Microphone System Operating Manual
There will be dierent, non-conicting channels in other frequency groups supplied
around the world so please check with your dealer or national supplier for this informa-
tion. Fit an Alkaline AAA battery into the battery compartment, re-t the lid and push
the sealed on/o button. A tiny blue LED illuminates to let you know it’s on. When that
LED starts ashing then the usable power is running low and it’s time to change the
battery. One AAA battery will
supply over 5 hours of air time. Re-chargeable AAA bat-
teries can also be used.
Using Multiple Transmitters At One Location
Please note that the MT-U8 is an 8 channel transmitter and will normally be supplied
lining up with channels 01-08 on the receiver. In some countries a “B” group of chan-
nels may also be available (Ch. 09-16). In both cases the channels line up with the same
number on the receiver and then repeat - so that channel 00 is also channel 08 on the
MT-U8. If you wish to use multiple MT-U8/SM716 systems under the one roof then at
least 4 channels can be used without causing interference with each other. In the case
of the 630-650MHz range, channels 1,4, 5 or 8 can be used together. If you are also us-
ing a beltpack transmitter in the same or another room nearby, then that should be set
to a channel in the 09-16 group, of which channels 10, 12,14 or 16 will work best with
channels 1,4, 5 or 8. There will be dierent, non-conicting channels in other frequency
groups supplied around the world so please check with your dealer or national supplier
for this information.
6. REMARKS
RF Interference
If you encounter receiving interference (from other than an operating TV station),
it can often be overcome by adjusting the receiver’s squelch control, as described
below. Please note that wireless frequencies are shared with other radio services, and
according to FCC regulations wireless microphone operations are unprotected from
interference from licensed operations in the band. If any interference is received by
any Government or non-Government operation, the wireless microphone must cease
operation. (The above statement is valid for the U.S.A.)
Receiver Squelch control
The squelch control on the back panel of the receiver is preset at the factory, but can
be adjusted if you must use the system in a high RF interference area. If there is audio
output from the receiver when your transmitter is OFF, adjust the squelch control so
the system will receive the signal from your transmitter but squelch or eliminate the un-
wanted background RF noise. This adjustment can cause a reduction in usable range of
the wireless transmitter, so set the control to the lowest position which reliably mutes
the unwanted RF signal.

Batteries
Many batteries are known to leak conductive and/or corrosive liquid when not used for
a period of time. Please remove the batteries from the transmitter if it is not to be used
for a period of a few days or more.
7. THE OPTIONAL HANDMIC
The Fitness Audio SDR5716 Receiver is compatible with
certain models of Chiayo handheld microphones such as
the SQ-1016 pictured below. For more information please
consult your Fitness Audio supplier. Please note that you
can only use one mic transmitter at a time with the FA Series
Receivers so make sure your other transmitter is turned o
before using a handmic transmitter.
