1. How to use the tripod-stand
Loosen the lower adjusting screw of the aluminium light-weight tripod and open the legs of the tripod (as amply
as space allows). Once you have found a solid stand, tighten lower adjusting screw.
Loosen the upper adjusting screw, position the pull-out tube at the height requested and tighten screw again.
Attention: make sure the ITEC AV-BOX does not collapse, particularly when used outdoors (wind).
2. How to start
- General:
Turn on the ITEC AV-BOX by turning the ON/OFF switch (1) to the right (position ON); the ON/OFF indicator
light (2) will show.
- Battery mode (optional):
In case the power supply is not plugged in, the ITEC AV-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 suffi cient power; it will be red if the battery is low. You can still operate the
ITEC AV-BOX, yet the device will switch off automatically when the power becomes too low (built-in discharge
protection).
- Mains supply:
In case the ITEC AV-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 off the ITEC AV-BOX the battery
will start recharging immediately with the mains indicator light (3) staying On and the ON/OFF indicator light
(2) disappearing (see 12. recharging the ITEC AV-BOX).
3. Using a 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). See 13. general advice ....
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 phantom supply: 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.

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).
5. Music attenuation
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.
Attenuation adjustment: while speaking into the microphone adjust 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).
6. 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 ITEC WT-702, ITEC WT-801 or AKG: This is the case when red LED fl ash after switching on; permanently
red light means to change the batteries.
Using ITEC WM-702 or TOA: This is the case when the green LED light shows; when the red LED light shows
the batteries should be replaced.

7. Connecting the ITEC LECTERN SUCCESS
Cable connection: the ITEC AV-BOX is connected to the LECTERN SUCCESS by means of the attached cable.
At the ITEC AV-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 ITEC AV-BOX shall be in proportion to the LECTERN SUCCESS; the best way of doing this is to
- set up the LECTERN SUCCESS and the ITEC AV-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 ITEC AV-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 ITEC
AV-BOX needs to have a radio receiver. The volume control WIRELESS (8) lets you choose how loud the ITEC
AV-BOX shall be in proportion to the LECTERN SUCCESS; the best way of doing this is to
- set up the LECTERN SUCCESS and the ITEC AV-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 ITEC AV-BOX/ES and turn up the volume (control
WIRELESS, 7) making sure that there is no feedback.
8. Recording
Connect a tape recorder, MD player or speech mike recording system to 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.
9. Connecting an external amplifi er
The adjusted signal of the ‘PRE OUT’ cinch socket (5B) may be connected to an external amplifi er (see 9.
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.
10. Connecting an external radio receiver
To connect an external radio receiver use socket 11 (1/4” mono jack) for audio line input. If needed 12V-DC is
supplied on socket 10 (500mA max)

11. DC 12V socket
For the use of additional ITEC equipment, e.g. the CONFERENCE SET, use socket (10) for voltage supply. The
maximum current is 0.5A, a built-in safety advice switching off the device in case of overcharge.
12. Recharging the ITEC AV-BOX (Option: rechargeable battery)
simply connect the ITEC AV-BOX to the mains (110/220V) and leave the ITEC AV-BOX switched off. The power
indicator light (3) is on, the ON/OFF indicator light (2) is not. After approximately 10 hours the battery will be fully
recharged. The power indicator light will remain on! The ITEC AV-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 ITEC AV-BOX for months we recommend you switch it on for several hours and then
recharge it.
13. 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 from the person speaking) and makes speaking more diffi cult
(sonic speed, as we now know, is not all that fast). We recommend a distance between mike and speaker
of between 5 and 15 metres.
- Furthermore, make sure the speaker does not face the mike directly.
- Perfect as the loudspeaker system may be, the person speaking ought to annunciate loudly and clearly.
An audience of 10 should be able to understand him perfectly 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 close 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 microphone/s anywhere near potential interference sources (computers,
mobile phones etc.)
