Three-channel mixing console
Sůra, Lukáš ; Boušek, Jaroslav (referee) ; Hejátková, Edita (advisor)
This work deals with the design and manufacturing of the three channel analog mixing consol. This console is capable of mixing low frequency signals. After a short introduction and distribution of panels is shown a block scheme and then designed circuit diagram. Each chanel is three-band, it is solved by using the equalizer combined with the logharitmic level controller (fader), the sensitivity controller (gain) and the interception button. The preamplifier and three-band equilizer are used to treat the microphone input. The mixing pult has six stereo inputs, three of them for the line levels signals (line in) and the last three inputs for a portable phonograph treated with pre-amplifiers (phono in). It also has three stereo line level outputs used by the main output (master out), the interception (booth out) and the headphones (headphones out). The output corrections are solved by using the five-band equalizer, which can be bridged. The linear level controller (crossfader) is placed beetwen channels. The logathmic level controller is used to setup the output signal.

Automatic lighting controls
Sůra, Lukáš ; Boušek, Jaroslav (referee) ; Hejátková, Edita (advisor)
This diploma work discusses the design of an automatic lighting for the home. Each access point in the rooms is designed to detect with two laser beams. Laser beams can be extended with PIR sensor and a mechanical switch. An access point can be, for example frames . By this is achieved that when entering the room the light is switched on and the light goes off when leaving. Automatic lighting controls consists of the central panel, the remote sensing and the detection frame. The control panel controls laser beams and lights. Remote control is used to switch on/off the light in the certain room. The detection frame is used to detect a person who enters or leaves the room.
