Description
(54) УСТРОЙСТВО ДЛЯ МАГНИТНОЙ ЗАПИСИ И ВОСПРОИЗВЕДЕНИЯ(54) DEVICE FOR MAGNET RECORDING AND REPRODUCTION
ЗВУКОВЫХ СИГНАЛОВSOUND SIGNALS
Толь записи 4 св зан с блоками 6 записывающих магнитных головок магнитофонов 7, а релейные узлы управлени 3 - с их лентопрот жными механизмами. РелеЯные узлы управлени соединены таК же непосредственно с усилителем записи 4. Блоки воспроизвод щих магнитных головок 8 магнитофонов 7 св заны через переключатель каналов 9 и усилитель воспроизведени 10 с громкогово- ритолем 11.The recording volume 4 is connected with blocks 6 of magnetic tape recorders 7, and the relay control nodes 3 are connected with their tape drive mechanisms. The relay control units are connected directly to the recording amplifier 4. The blocks of reproducing magnetic heads 8 of tape recorders 7 are connected via a switch of channels 9 and the amplifier of reproduction 10 with a speaker 11.
Предлагаемое устройство содержит также регистр сдвига 12 и первый блок кодировани 13, подсоединенные к выходам формировател сигналов команд 1, и соединенные последовательно компаратор 14 -кодовых маркеров, второй блок кодировани 15 и блок запоминани программ 16, При этом компаратор 14 подсоединен через счетчики 17 к блокам 18 магнитныхголовок кодовых сигналов магнитофонов 7, а блок запоминани программ 16 - к выходам регистра сдвига 12 и первого блока кодировани 13 и к входу формировател сигналов команд 1. Формирователь сигналов команд соединен также с входами переключател каналов 9 и усилител воспроизведени 10 и с компаратором 14 кодовых -маркеров.The proposed device also contains the shift register 12 and the first coding block 13 connected to the outputs of the signal generator commands 1, and the serially connected comparator 14 -code markers, the second coding block 15 and the program memory 16, the comparator 14 is connected through the counters 17 to the blocks 18 magnetic heads of the code signals of tape recorders 7, and the program memory block 16 to the outputs of the shift register 12 and the first coding unit 13 and to the input of the command signal generator 1. The driver of the command signals Also, with the inputs of the channel selector 9 and the playback amplifier 10 and with the comparator 14 code markers.
В предлагаемом устройстве пор док работы магнитофонов 7 в процессе воспроизведени набираетс на пульте управлени и запоминаетс в блоке запоминани программ 16. Поиск записанных звуковых сигналов в процессе воспроизведени производитс по кодовым маркерам, воспроизводимым магнитофонами 7 и сравниваемым с кодом, выдаваемым блоком запоминани программ. In the proposed device, the order of operation of the tape recorders 7 in the process of reproduction is typed on the control panel and stored in the program memory 16. The recorded audio signals in the process of reproduction are searched for by the code markers reproduced by the video recorders 7 and compared with the code output by the program memory.
Использование изобретени позвол е в значительной степени упростить процесс обслуживани устройства дл The use of the invention allows to significantly simplify the process of servicing the device for
магнитной записи воспроизведени звуковых сигналов и обеспечивает высоцук скорость поиска записанных звуковых сигналов. Предлагаемое устройство может найти применение дл автоматизированного воспроизведени музыкальных программ.magnetic recording playback of audio signals and provides a high speed search for recorded audio signals. The proposed device can be used for automated playback of music programs.
