1. Saftey instructions
Don’t try to open the device forcibly or with unfixing of the bolting. The device doesn’t contain any parts which
could be repaired by laymen. For help contact the manufactorer or the distributor.
Take care that no fluid (coffee, wine, ect.) is poured over the device. If this is happened, the device has to be
switched off immediately, be unpluged and checked by a practitioner.
Don’t expose the device to a temperature more than 50°C, a humidity more than 95% or heavy rainfall.
ATTENTION: Also when the device is unplugged on account of the integrated accumulator coused by a not
appropriate intervention short circuits are possible which can lead to demage or to a heat growth. By any
intervention of a practitioner the device has to be unplugged.After the carefully removal of the cover separate
the connection cable form the accumulator.
2. How to stand the POWER-BOX
Loosen the lower adjusting screw (a) of the aluminiumlight-weight tripod and open the legs of the tripod
(asamply as space allows). Once you have found a solid stand, tighten lower adjusting screw.
ITEC POWER-BOX
The height of the tripod can be changed by the upper adjusting screw
(b); bear in mind, however, that what you gain in height you lose in
stability!
Another option is an elevator tripod. The crank is used to adjust the
high of the tripod.
ATTENTION: make sure the POWER -BOX does not collapse, particularly when it is windy!

3. How to start
General:
Turn on the POWER -BOX by turning the ON/OFF switch (1) to the right (position ON); the ON/OFF indicator
light (2) will show.
Battery mode:
In case the power supply is not plugged in the POWER -BOX will be supplied by an integrated rechargeable
battery. The average operating time with a fully charged battery will be 6 to 10 hours.
The ON/OFF indicator light will be green if the battery has sufficient power; it will be red if the battery is low.
You can still operate the POWER -BOX, yet the device will switch automatically when the power becomes too
low (built-in discharge protection).
Mains supply:
In case the POWER -BOX is connected (socket 10) to the mains supply (220V), the red mains indicator light
(3) will show in addition to the ON/OFF indicator light (2).As soon as you switch POWER -BOX the battery will
start recharging immediately with the mains indicator light (3) staying On and the ON/OFF indicator light (2)
disappearing (see 13. recharging the POWER -BOX).
Maximum sound intensity:
Different audio sources ( CD’s, mp3-files, … ) cause different sound intensities. Therefore it can happen that
by maximum volume the box is used over its max capacity limit. The POWER -BOX owns a limiter, which
limits the capacity. The Peak-Indicator-LED (12) shows the reaction. Temporary indication flashing means no
lost of playback quality, the electronic system regulates the volume itself. If the indication is glowing continu-
aly the volume has to be reduces manually.
4. Playback
The cinch sockets (5A) will accept any tape recorder, CD player, radio, etc. The volume can be adjusted at
the corresponding control (7). Should your POWER - BOX have a built-in tape recorder or CD player, please
do not forget to consult the instructions enclosed.

5. Handling with cable microphone
Plug in the cable microphone in the microphone socket (4) and adjust its volume at the volume control for the
cable microphone (6).
Technical information:
The multi-jack microphone socket (3) lets you plug in microphones with XLR or 1/4” jack.
Use either dynamic microphones or electret condenser microphones.
Connecting balanced microphones: by means of a XLR plug or a stereo ¼” jack.
Connecting balanced microphones with phantomsupply: by means of a XLR plug.
Connecting unbalanced microphones: by means of a mono ¼” jack.
In case you have a long microphone cable, an interference free operation can only be guaranteed when you
use both balanced microphones and balanced microphone cables.
Attenuation adjustment: while speaking into the microphone ad-
just the playback volume you want during your announcement.
Attenuation will be started when using a radio microphone or
cable microphone and takes effect on music playbacks via the
line-in socket (external equipment) and any built-in devices (tape
recorder or CD player).
Attenuation is triggered by radio microphones or by a cable
microphone.
We recommend the ITEC EM 300 electret
capacitor microphone
6. Music attenuation (optional)
Should your device have an automatic music attenuation the volume of the music playback will be turned
down while somebody is speaking. You determine the volume of the attenuated playback by means of the
appropriate control (9).
control position left: while speaking, the music is turned off completely
control position middle: while speaking, the music volume is halved
control position right: even while speaking, the music volume remains the same,
i.e. no attenuation at all.

7. Using a radio microphone
switch on the radio microphone and adjust the volume at the corresponding control (8).
See 13. General advice.
When using a radio microphone make sure the batteries are alright:
Using WM-702, WM-802 or TOA: This is the case when the green LED light shows;
when the red LED light shows the batteries should be replaced.
8. Separate control with two radio receiver
Even when there are 2 built-in radio receivers the volume is normally adjusted with control (8). Should you
need to adjust the receivers separately you can do so by using the optional control (12) for the 2nd recei-
ver.
9. Connecting the ITEC LECTERN SUCCESS
Cable connection: the POWER -BOX is connected to the LECTERN SUCCESS by means of the attached
cable. At the POWER -BOX plug the signal cable in one of the CASS/CD LINE IN cinch sockets(5a), at the
LECTERN SUCCESS plug it in one of the LINE OUT cinch sockets. The volume control CASS/CD (7) lets
you choose how loud the POWER -BOX shall be in proportion to the LECTERN SUCCESS; the best way of
doing this is to
· set up the LECTERN SUCCESS and the POWER -BOX/ES, connect them with the devices left off;
· connect the microphone to the LECTERN SUCCESS;
· switch on the LECTERN SUCCESS and adjust the volume;
· switch on POWER -BOX/ES and turn up the volume (control CASS/CD, 7) making sure
that there is no feedback.
Radio transmission: requirements: the LECTERN SUCCESS needs to have a radio transmitter, and the PO-
WER -BOX needs to have a radio receiver. The volume control WIRELESS (8) lets you choose how loud the
POWER -BOX shall be in proportion to the LECTERN SUCCESS; the best way of doing this is to
· set up the LECTERN SUCCESS and the POWER -BOX/ES, connect them with the devices left off;
· connect the radio transmitter to the LECTERN SUCCESS: plug an MC 12 in one of the LINE OUT
cinch sockets;
· connect the microphone to the LECTERN SUCCESS;
· switch on the LECTERN SUCCESS and adjust the volume;
· switch on the radio transmitter and POWER -BOX/ES and turn up the volume
(control WIRELESS, 7) making sure that there is no feedback.
10. 12V DC – Output - jack
When using ITEC – supplementary devices, for example the CONFERENCE – SET, it is possible to use the
supply voltage on this jack (10). Maximum current amounts 0,5A – an installed automatic safety device swit-
ches off when an overload takes place.

11. Recording
Connect a tape recorder, MD player or speech mike recording systemto the ‘PRE OUT’ cinch socket (5B).
You can record cable microphone, radio microphone and music playback. The output level will depend on
how you have adjusted the controls.
12. Connecting an external amplifier
The adjusted signal of the ‘PRE OUT’ cinch socket (5B) may be connected to an external amplifier (see 10.
Recording). However, in most cases, the integrated radio receiver will be needed. In this case, please plug in
the ‘HF LINE OUT’ (5C) socket.As for volume, be aware that now the signal of the radio receiver/s overrides
your volume adjustments.
13. Recharging the POWER-BOX
Simply connect the POWER-BOX (10) to the mains (110/220V) and leave the POWER -BOX switched off.
The power indicator light (3) is on, the ON/OFF indicator light (2) is not.After approximately 10 hours the bat-
tery will be fully recharged. The power indicator light will remain on! The POWER-BOX can remain plugged
in without causing any damage.
Maintenance of the battery
The integrated lead battery is rechargeable and maintenance free; however, a few basic rules ought to be
heeded:
Do not store below a temperature of 5°C
Recharge after use.
Not having used the POWER-BOX for months we recommend you switch it on for several hours and then
recharge it.
14. General advice
Do not place microphones and speakers close to each other in order to avoid acoustic feedback; too great
a distance, on the other hand, between microphone and speaker has an unnatural effect on the audience
(the sound, bear in mind, does not come fromthe person speaking) and makes speaking more difficult (sonic
speed, as we now know, is not all that fast). We recommend a distance between mike and speaker of bet-
ween 5 and 15 metres.
Furthermore, make sure the speaker does not face the mike directly.
Perfect as the loudspeaker systemmay be, the person speaking ought to annunciate loudly and clearly. An
audience of 10 should be able to understand himperfectly well without any technical support.
The distance between the mouth and the microphone should be between 5 and 10 cms. It is advisable always
to have an attendant near the loudspeaker controls, e.g. should the person speaking suddenly come too clo-
se to the speaker with his mike the resulting feedback could be remedied.
Advice on radio microphones: Make sure the batteries of the radio microphone/s are in good condition. High
voltage cables, iron gates, metal roofs, etc. can cause interference. Do not place the receiver or the micro-
phone anywhere near potential interference sources (computers, mobile phones etc.).
