HumanTechnik Crescendo 50 Mode D'emploi page 10

Signal reception
Acoustic signals can be picked up by the amplifier in four different ways:
1. The acoustic signals are picked up by the built-in microphone, whereby the
operating mode selector in the battery compartment must be set to
»M« (factory default setting for the Crescendo 50 ).
2. Acoustic signals from television sets or other audio devices can be picked
up by the plug-in microphone included with the system. Simply plug this
microphone into the microphone jack. (If an external microphone is used, the
built-in microphone will be switched off automatically.) In addition, the opera-
ting mode selector in the battery compartment must be set to »M«.
3. Audio signals can also be picked up by a stereo/audio cable. In this case,
the operating mode selector in the battery compartment must be set to »A«.
Connect the audio cable with the Crescendo 50 and the audio source (e.g.
television set).
4. To pick up signals from an induction loop system, the operating mode selec-
tor in the battery compartment must be set to »T«. Please note that any
microphone connected must be disconnected first.
Switching the device on
To switch the amplifier on, turn the volume knob clockwise until you click past a
noticeable resistance. The ON/OFF indicator will light up to show you that the
device has been switched on.
Setting the volume/tone
Adjust the volume control to set the device to the volume you prefer. Use the tre-
ble/bass control knob to adjust the tone; the treble and the bass will be increa-
sed accordingly.
Switching the device off
To switch the amplifier off, turn the volume knob counter-clockwise until you click
past a noticeable resistance. The green ON/OFF indicator will switch off.
