Description

  The present invention relates to a performance monitor device, a control room call unit, a signal distribution device, and a studio call system, and more specifically, a performance monitor that is installed in a music studio or the like and used for conversations or the like in the music studio. The present invention relates to a device, a control room call unit, a signal distribution device, and a studio call system.

  Conventionally, music studios are used to record singing voices sung by musicians and the like and performance sounds of various musical instruments, and a method for improving the recording sound quality in the music studios is disclosed in Patent Document 1 below. .

  The music studio is composed of an adjustment room (also called a control room) and a performance room (also called a booth), and the adjustment room and the performance room are partitioned by a panel or the like. Therefore, a separate studio call system (talkback system) is required in order for a person in the adjustment room and a person in the performance room to have a conversation.

FIG. 3 is a block diagram schematically showing a main part of a studio call system in a conventional music studio.
The performance room 1 includes a microphone (hereinafter referred to as a microphone) 3 for each performer and a performance monitor device (also called a cue box) for monitoring recorded performance sounds and call voices from the adjustment room 2. Say 100).

  Each call microphone 3 in the performance room 1 is connected to a mixing console (hereinafter referred to as a mixer) 40 in the adjustment room 2 via a microphone cable 4, and each performance monitor apparatus 100 has a plurality of channel signals. The signal distribution device 200 of the adjustment chamber 2 is connected via a multi-cable 30 capable of transmitting the signal.

  The performance monitor apparatus 100 includes a connection connector 11 to which the multi-cable 30 is connected, and adjustment means for adjusting the levels of signals of a plurality of channels transmitted through the multi-cable 30 connected to the connection connector 11 (so-called , A simple mixer) 12 and an output terminal 13 for outputting a signal adjusted via the adjusting means 12. The level of the signals of a plurality of channels is arbitrarily adjusted to obtain a desired monitoring environment. It can be set, and by connecting a headphone 31 to the output terminal 13, it is possible to monitor a performance sound or a call voice. In the performance room 1, a recording microphone (not shown) for recording the performance sound is installed for each performer, and the recording microphone is also connected to the mixer 40 via a microphone cable (not shown). Each is connected.

  On the other hand, the adjustment room 2 is provided with a signal distribution device 200, a call microphone 5, a mixer 40, an amplifier 41, and a speaker 42. The call microphone 5 is connected to the mixer 40, and the mixer 40 includes an amplifier 41. And a signal distribution device 200 are connected.

  When a plurality of audio signals collected by a recording microphone installed in the performance room 1 or a sound signal input through the call microphones 3 and 5 is input to the mixer 40, the plurality of input audio signals are input. These signals are mixed and output to the speaker 42 via the amplifier 41 to be output as performance sound or call voice, or the signals of these plural channels are transmitted to the signal distribution device 200.

  The signal distribution device 200 distributes signals of a plurality of channels transmitted from the mixer 40 and transmits the signals through the multi-cable 30 to each performance monitor device 100 installed in the performance room 1.

  Next, the operation of the conventional studio call system during a call will be described. First, a case where a person in the performance room 1 makes a call to a person in the adjustment room 2 will be described. When sound is input with the call microphone 3 of the performance room 1 in the input state, the sound signal input through the call microphone 3 is input to the mixer 40 via the microphone cable 4 and mixed, The sound is output from the speaker 42 via the amplifier 41.

Next, a case where a person in the adjustment room 2 receives a voice output from the speaker 42 and makes a call to a person in the performance room 1 will be described. When voice is input with the call microphone 5 of the adjustment room 2 in the input state, the voice signal input through the call microphone 5 is transmitted to the signal distribution device 200 via the mixer 40, and is transmitted by the signal distribution device 200. After being distributed, it is sent to each performance monitoring device 100 via the multi-cable 30. In each performance monitor device 100, the sound signal transmitted from the signal distribution device 200 is output as sound through the headphones 31 connected to the output terminal 13.
In this way, using the call microphone 3 installed in the performance room 1 and the call microphone 5 installed in the adjustment room 2, a necessary conversation can be performed between the performance room 1 and the adjustment room 2. ing.

  However, in the conventional studio call system, it is necessary to prepare the call microphones 3 of the performance room 1 for the number of persons and connect these call microphones 3 to the input channels of the mixer 40 respectively. There was a problem that it took time and effort.

Further, in the mixer 40, the input channel of the mixer 40 occupies as many as the number of connection of these call microphones 3, 5 for connection to the call microphone 3 in the performance room 1 and the call microphone 5 in the adjustment room 2. As a result, there has been a problem that the number of input channels of the mixer 40 for connecting a recording microphone or a musical instrument is reduced.
