FP-22 modular
The EasyPort FP-22 are self-powered loudspeakers. A built-in 4
channel mixer with 2-band equalizer lets you connect a media player
or similar audio source, two wired microphones, and the supplied
wireless microphone for simultaneous operation. Up to 4 built-in
radio receivers are possible.
The FP-22 is optionally equipped with an integrated Bluetooth-
MP3/WAV-Player.
The EasyPort is also available with a pre-installed wireless receiver
that provides highly reliable and excellent audio quality. A handheld
or bodypack transmitter of your choice (optional) makes the EasyPort
a self-contained sound system for use with hardwire or wireless
microphones.
For mains independent operation, the EasyPort features a built-in
high quality, leakproof lead gel rechargeable battery that conforms
to the strict standards of the German Association of Casualty
Insurers.

4.3.1 Bluetooth-MP3/WAV-Player (Option) OVERVIEW OF THE CONTROLS
Your Bluetooth MP3/WAV player consists of 2 separate basic devices,
each of which can be separately adjusted and switched on via its own
volume control.
The Bluetooth receiver on the left side, as well as the MP3/WAV
player with USB and SD card slot on the right side can in principle be
operated in parallel when both devices are switched on. The total
volume of both single sources can be adjusted via the volume knob
(6) in the overall mix of the FP-22.
The MP3/WAV player has several playback modes: the standard
playback (basic functions) can be done directly on the MP3/WAV
player. The advanced playback functions can only be accessed using
the supplied remote control.
It supports the formats: MP3, WAV and WMA and can play them from
memory sticks via the USB port (35) or SD/MMC cards via the card
slot (36). These media must be FAT or FAT32 formatted.
For the Bluetooth receiver part on the left side, only the controls
"volume control/on/off knob" and a "pairing button" are available
directly on the device. All other settings such as track selection, start,
stop, etc. are operated directly on your Bluetooth transmitting device
(smartphone, etc.).
Remote control
The infrared remote control can only call up the functions of the
MP3/WAV player, i.e. not the volume controls of the microphones.
All basic function keys correspond 1:1 to the symbols on the player.
The extended operation is listed separately in the lower part of the
table. The infrared receiver (38) should always be visually accessible
when using the remote control. Due to the infrared technology, the
remote control is not suitable for outdoor use. The infrared signal is
affected by sunlight.

BASIC FUNCTIONS of the Bluetooth player (available
without remote control)
(31-33) Operation of the bluetooth receiver
When the Bluetooth receiver is used, it must first be switched
on via the rotary switch (31) and a basic volume must be set
on it.
If the receiver was not switched off after the last use, it is
automatically supplied with power after switching on your
FP-22 and is functional. If a compatible Bluetooth device has
already been connected in the past, the green "LOCK" LED
will light up and a confirmation tone will sound. The receiver
is now ready for playback and appears as "BT AUDIO" in your
playback device (e.g. smartphone or notebook...).
If no already tuned-in Bluetooth transmitter device connects
to the player at startup, the player automatically switches to
"pairing mode" after a few seconds. Both LEDs (33) flash
alternately green and red. Now the device is ready to receive
pairing requests from your playback device and can be found
by your sending device under the name "BT AUDIO". After
successful connection, the confirmation tone will also sound,
the "LOCK" led will light green and the receiver is ready to
play.
To initiate the pairing manually press the "LINK" button (32).
All further control commands (track selection, rewind,
start/stop, etc.) are performed on your paired playback
device.
BASIC FUNCTIONS of the MP3/WAV player (available

When the MP3/WAV player is used, it must first be switched
on via the rotary switch (34) and a basic volume set on it. If
the player was not switched off after the last use, it will be
automatically supplied with power after switching on your FP-
22. The player will automatically start playing the last selected
track, if a media is already inserted. If not, insert your
playback media (USB stick/SD/MMC card) into the designated
slots (35) and/or (36). The last selected source is prioritized
and played automatically after a short time. You can change
the playback medium by removing the medium you do not
want from its socket. The storage media can be removed from
the player at any time. SD/MMC cards are unlocked for this
purpose by pressing lightly on the back, just as when inserting

5. Setting Up
5.1 Operating Environment
1. Acceptableambienttemperatureduringoperationrangesfrom
-5˚C to +40˚C.
2. Acceptable temperature during storage or shipping ranges from
-15˚C to +40˚C.
3. If condensation has formed on the equipment or the rear panel
during shipping or storage, allow the unit to acclimate for 2
hoursbefore poweringup.
4. The loudspeaker has been designed for use in a dry
environment with air of normal relative humidity and dust
concentration. Never expose the unit to aggressivechemical
liquids or vapors.
5. You can position the unit at any angle. Make sure, though, to
provide at least 4 inches of free air space behind the rear panel
for adequateventilation.
5.2 Audio Connections
1. Set all VOLUME controls (6), (22), (9) and (12) to zero.
2. Connect the desired audio source (e.g., cassette player, CD
player) to the LINE INPUT jacks (5) or (23) using a standard
cable.
3. Use a commercial XLR cable to connect your wired microphone
to the INPUT connector (8) or (26).
4. If you want to record your performance or presentation,
connect a (cassette, DAT, tape or other) recorder to the LINE
OUT jack (7) or the mix-out jack (25) (turn switch (24) in the
„mix-out“ position) using standard jack or XLR cable.
5. For consistent audience coverage, you can use another FP-22
modular. Connect the LINE OUT jack (7) or (25) to the LINE IN
jacks (5) or (23) of the other FP-22 modular.
4. EasyPort is ready tooperate.
5. Unplug the IEC cable from the recharge battery jack (1).
When the FP-22 modular is switched on (3), the LED (4) lights
up green if the power pack is fully charged.
When the power pack falls below 30% capacity, the LED starts
to flash red.
If the power pack voltage is decreasing, the LED flashes red
increasingly quickly until it lights up red continuously.
After the LED is lit for 10 seconds, the FP-22 modular switches
off to prevent the power pack from an exhaustive discharge.
A signal sounds when the FP-22 modular switches off.
Recharge the battery as per steps 1 through 4.

Depending on the load, battery operating time will be
8-18 hours.
Since the battery has no memory effect, you will not need to
discharge it fully before charging. Therefore, you can start charging
at any time irrespective of the battery`s residual capacity.
Lead batteries should not be stored for extended periods of time in
entirely orpartially discharged condition. Wetherefore recommend
to recharge the battery immediately after use.
In order to made sure the EasyPort is always ready to operate, it is
best to leave it connected to AC power whenever you do not use it.
5.3 Powering Up (BatteryOperation)
The EasyPort FP-22 modular has been designed primarily for battery
operation. Before first operating the EasyPort or if the unit has not
been connected to AC power for more than a year, charge the
battery for 14 hours.
1. Plug the IEC cable into the recharge battery jack (1) on the
EasyPort FP-22 modular rear panel.
2. Check that the AC mains voltage stated on the supplied AC
adapter is identical to the AC mains voltage available where
you will use your FP-22. Using the AC adapter with a different
AC voltage may cause irreparable damage to theunit.
3. Connect the IEC cable to a convenient power outlet. Do not
use switched outlets!
Charging will start automatically and the yellow Charging LED
(2) will light constantly. When the yellow Charging LED (2) starts
flashing the battery is fully charged and the EasyPort is ready to
operate.
5.3.1 Total Discharge Protection Circuit
Discharging a battery totally may cause extensive damage. We
therefore provided the electronic circuitry of the EasyPort with an
intelligent protection circuit that effectively prevents the battery
from being totally discharged. The protection circuit automatically
isolates the entire EasyPort electronics from the battery and
switches the loudspeakers off before battery capacity approaches
the total discharge threshold. If this happens, recharge the battery
immediately.
