System Overview
Thank you for choosing the Enersound T-588 FM transmitter. This 2-Watt stereo
transmitter wirelessly broadcasts a speaker’s voice, music, or any audio signal in
the 88.1-107.9 MHz frequency band (US version.) The T-588 transmitter features 3
main audio inputs that allow the direct connection of virtually any analog audio
source, including a 3.5 mm jack for headset microphones, an XLR & ¼ inch
combination jack with a selector for dynamic microphones, condenser
microphones or line-level signals, and RCA stereo auxiliary input. It also has a
recording output and a 3.5 mm monitor headphone jack.
For interpretation or audio description, it has a unique integrated interpreter or
narrator monitor function. This feature allows interpreters/ narrators to select an
external incoming audio source and utilize a headset with microphone to listen to
the source language/ audio without the need of an interpreter console or external
headphone amplifier. Through the headphones’ volume control, interpreters/
narrators can set the desired incoming audio level and the [MUTE] button allows
them to momentarily silence their microphone for coughing or sneezing.
Its LCD display allows to visualize the frequency being broadcast, as well as to
easily program the various useful functions, such as RF power level and
mono/stereo transmission.
For use in the USA, please contact your local FCC office for information regarding
permit or license that may be needed based on your application.
For use in Canada, please contact your local Industry Canada office for information
regarding permit or license that may be needed based on your application.
For use outside the USA and Canada, please contact your local telecommunications
authority regarding permit or license that may be needed based on your
application.

General Set-up Instructions:
Unpack the transmitter.
Remove outer packaging and plastic cover. Inspect for physical damage and
immediately report any issues to Enersound.
Position the unit.
Position the transmitter away from metallic objects that might interfere with
the antenna or any electromagnetic noise sources such as transformers,
motors, dimmers, etc.) This transmitter is designed to be use in a dry
environment, in temperatures ranging from 23F (-5℃) to 104F (40℃).
The antenna should be located as close to the center of the coverage area
as possible, and at a sufficient height to give the transmitted signal an
unobstructed path to every receiving point. Transmitted signal paths will
be weakened by concrete walls, steel beams, dense materials, or metal
objects.
Connect the antenna.
Screw in the included telescoping antenna onto the transmitter antenna
connector located in the rear panel. Alternatively, an optional remote 50-ohm
antenna with TNC connector can be used to increase the range. Make sure the
remote antenna matches the specific frequency in which you intend to
broadcast.
For your convenience, a telescoping antenna
is included with the transmitter for use in
small areas (up to 650’ line of sight with car
radios). The range with this antenna is
significantly shorter than the range with a
remote antenna that is specifically crafted for
the desired frequency. Also, this antenna has
a shorter range on higher frequencies.
When using the telescoping antenna, the rod
length should be adjusted as follows:
1) Choose a free frequency
2) Use the chart (Fig 6.) to note the associated length (ex: 88.5MHz = 44 ½”).

8
3) With the help of a measuring tape or ruler; extend the telescopic antenna in
a manner to obtain the desired length (from base to tip of antenna.)

Connect Audio Inputs
The T-588 has several audio inputs:
Rear Panel:
Input 1: For balanced or unbalanced connections using either an XLR or 1/4”
phono connector. Ideal for connecting audio mixers, dynamic microphones
or 12V condenser microphones.
Plug your balanced or unbalanced audio source into Input 1. Use the
following diagram.
Note: Input 1 is a mono input. For true stereo signals, use Input 2. If you still wish
to use Input 1 with a stereo signal, use a simple resistive mixer as shown above
utilizing two 4.7KΩresistors available at a local electronic components’store.
Input 2: Two RCA (left and right) auxiliary line level inputs. This is a true
stereo input.

HAZARD! Pacemaker Safety
Before using this transmitter and/ or receivers with a pacemaker or another
medical device, consult your physician or the manufacturer of your pacemaker
or another medical device.
If you have a pacemaker or another medical device, make sure that you are
using this transmitter and/or receivers in accordance with safety guidelines
established by your physician or the pacemaker manufacturer.
WARNING! Damage to your Health
Using earphones or headphones at a loud volume or over a prolonged period
can lead to permanent hearing damage. To protect your hearing and others:
a) Turn down the volume before putting on the earphones or headphones.
b) Adjust the volume at the minimum comfortable level.

13
c) If feedback (a squealing or howling noise) occurs, turn down the
headphone volume, and move the microphone away from the receiver’s
headphones.
Other Safety Considerations
Do not leave the device in places with high temperatures or high humidity.
Do not handle the power cord with wet hands.
Keep this device away from fire and heat sources.
Keep this product, accessories and its packaging out of the reach of children.
Plastic bags, packing material, electrical cords and other accessories may cause
choking, suffocation and/or electrocution!
Do not open the unit. There are no user serviceable parts inside.
Reduce the volume to its lowest setting before use.
To clean, be sure to first switch off and unplug the unit from the power outlet,
then wipe with a dry cloth. When extremely dirty, use a soft cloth dampened in
neutral detergent. Never use benzene, thinner or chemically treated towels,
which may damage the product’s finish.
Trouble shooting
The transmitter will not power.
Verify that the PS-500 power supply is connected to a working power
source and to the transmitter.
Make sure you are pressing and holding the [POWER] button for 5
seconds.
There is no audio on the transmitter’s headphones output.
If you are using the monitor headphones for language interpretation,
make sure the monitor selector is set to EXT (External audio).
Verify that the external audio signal is connected to the external audio
input jack.
Verify that there is a signal coming from your audio source.
If you are using the headphones to monitor the broadcasted audio, make
sure the monitor selector is in the INT (Internal) position.
There is no audio, or the audio is low on the receivers.
Make sure that the main volume is turned up and that your audio source
is properly connected. If using Input 1, the mode selector switch should
be in the correct position. For example: if you are using the output of a
mixer, the switch should be in the LINE position. If using a dynamic
microphone, the switch should be in MIC and if using a 12 V condenser
microphone, the switch should be in MIC PH-PWR.

14
If the audio level is still low, make sure that the gain knob on the rear
panel is turned up.
If using the front microphone jack, make sure that the mute function is off
and that you are using a compatible microphone in working condition.
There is noise or distortion in the audio.
Verify if the audio input level is too high that overloads the input. Adjust
the gain if necessary. If using input 1, make sure you are using the correct
mode selector switch.
Check to see if there is noise or ground loops in the audio source.
Receivers cannot pick up the signal.
Make sure that the transmitter and the receivers are turned on.
Check to make sure the receivers and the transmitter are using the same
frequency.
Ensure the antenna on the transmitter has been properly connected.
There is insufficient range.
Verify that your receivers are working properly.
Make sure the antenna is the correct one for your unit and is adequately
attached to the transmitter with the correct length following the chart
provided in this manual. if you are using a remote antenna, make sure it
was designed for the frequency you intend to use.
If using a remote antenna, keep coaxial cable from transmitter to antenna
as short as possible.
Make sure the transmitting antenna is oriented vertically.
The antenna should be placed as high as possible and free of obstacles.
Avoid placing it inside metal enclosures. Avoid obstacles between the
listening area and the antenna that may affect the signal strength, like
partitions, metal objects, dense materials, studs, pipes, heating or AC
ducts, metal grids or concrete.
Set the transmitter to a higher power level.
Try using a different channel/ frequency since a strong interfering signal
may exist.
Try better receivers. Car radios have longer range than portable radios.
