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.

Mixing console for audio signals
Špaček, Jan ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor's thesis on the theme "Mixing console audio signals" deals with the design of mixing console for mixing audio signals from several audio inputs. After a theoretical introduction to general issues and configuration mixing consoles the block diagram and then the full circuit diagram of a custom solution mixing console is proposed, whose configuration is as follows: Two mono inputs, designed as a switchable, where you can bring the microphone or line signal levels. They are equipped with a microphone preamp and attenuation articles, tri-band equalizers, panoramas and level controllers (faders). In addition, two stereo inputs, specifically designed for line level signals. They are equipped with line-preamp, panoramas and level controllers. Output signals of all input units correspond to a regular line level. On the main bus is then equipped stereo band equalizer, line output and headphone output. Bachelor's thesis comprises a technical documentation to implement functional prototype of the console, including the experimentally measured values.

Mixing console for audio signals
Ryšavý, Ondřej ; Kufa, Jan (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor’s thesis on the topic „Mixing console for audio signals“ deals with the design and production of a mixing console for mixing several independent audio channels. In the first step is designed a block diagram and then a circuit diagram. The overall configuration of the mixing console is: Four mono inputs, designed as a combined XLR/JACK 6,3 mm input, where you can connect a microphone or other mono signal (not both at the same time), two stereo inputs RCA(CINCH). Each channel allows five-band frequency correction, panorama, signal level control and signal level detection. The output is realized per line connectors (for connection to the amplifier), headphone output and headphone amplifier. After design, the mixing console is producted, revived and then measured in an audio laboratory.

The instrumentation of the theater hall
SUFČÁK, Pavel
The goal of this bachelor thesis is to summarize technical equipment of the theater hall in Prachatice, make calculations of reverberation times of specific hall and come up with adjustments to improve acoustic characteristics of examined hall. Come up with electroacoustic improvements of installed technical devices in the hall and make a list of improvements for future.
