Preamplifier with six symmetrical inputs to connect any type of audio source, with the first two channels for both microphone and line level audio sources, with 3-band tone control, phantom power and priority over the rest of the inputs. The other four channels are ready for connecting line level audio sources. On the front panel are the main output volume control, the 2-band tone control, the output level meter and the input volume controls for the channels. On the rear of the preamplifier there is a priority (mute) contact that suppresses all non-priority audio signals in case of contact closure and allows integration with external alarm systems. The built-in music source has an FM radio tuner and a player for MP3 files from USB sticks or SD memory cards.
