2. Using and general notices.
The modern amplifiers AMC- DSP4 (Powermixer) are designed to be used in sacral buildings, large, closed areas,
conference rooms, where the high quality and the hearing of speaking is required. They
are cooperating with the
50V, 70V and 100V loud speakers line and with the loud speakers set of altogether impedance > = 4 Ù.
The amplifier has got: 8 symmetrical microphone line channels to put in the dynamic, capacitive and wireless
microphones or the device with line level output and music channel to put in the record player, tuner or CD player
(LINE asymmetrical). To record, there is a separate RCA (RECORD) socket.
AMWL-DSP is a modern amplifier equipped in signaling DSP processor that enables precise correction of sound
characteristics in buildings with very difficult acoustic conditions. The amplifier activates only those microphones,
that are used in that moment, what eliminates sound surrounding influence coming from not used microphone
channels. Each 1-8 channel is equipped in symmetrical XLR input, sensitivity regulation, Phantom power.plugged
in, microphone/line switch, 100Hz high pass filter, preamplification regulation, and timbre regulation
(bas/soprano) designed in front of the case. In 1-8 channels, diodes signal the channel activity and the microphone
transposition.
