2 Applications
The amplifier PA-803USB with integrated MP3
player and an RMS output power of 30 W is e. g.
suitable for the use in small PA systems. In addition
to the mains operation, also a 12 V operation is
possible (e. g. with a car battery) so that it is also
suitable for mobile applications. Either use 100 V
.
speakers or low impedance speakers (minimum
impedance 4 Ω) [see figs. 3a and 3b].
The amplifier is equipped with 3 inputs:
– Microphone input MIC 1 for important announce-
ments taking priority over all other inputs, i. e.
with a signal present at the input, the signals of
the other inputs will be faded out (automatic
talkover)
– Microphone input MIC 2
– Input AUX / PHONO e. g. for CD player, radio,
tape deck or turntable
3 Setting Up the Amplifier
The amplifier can be set up as a tabletop unit or be
fixed at a suitable place, e. g. below a shelf, by
means of the supplied mounting brackets which are
laterally screwed to the housing. In order to ensure
a sufficient cooling of the amplifier, air must always
be able to flow freely through all air vents.
