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.
