POWER-BOX
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.).
