It is intended for the organization of wire circuits of sound notification and operative communication at railway and bus stations, enterprises, autoparks, clubs, vacation spots, etc.
Provides:
Translation of command and broadcasting transfers using 9 basic lines from various sources of a signal: a microphone, the tape recorder, tuner and transmitting line, supports mixing.
Supports two microphones link up, the tape recorder (or a transmitting line) and a player both separately and all together using any quantity of lines.
Switching on/off of timbre, noise blanking and tonecompensation regulators for sources of a signal.
Selection of any line at the indicator or sound control of operating modes.
Operative selection and conversation between operators of remote posts (RP) without blocking the line.
Connection of up to 9 RP and broadcasting from any of them in a chosen direction.
Indicator and an internal loudspeaker serial control using control panel (CP) of inputs and outputs of each power amplifier (PA) connected to a corresponding line.
Advantages:
- Opportunity of remote turn on of the complex when the broadcasting is carried out from ÖÓÑ, CP and RP.
- Opportunity of parallel connection of PA for increase of output capacity.
- The set of equipment can be manufactured in separate blocks or in a case?(when ordered).
Structure of broadcasting center ÐÓ-1000
- Power amplifier (PA) 10 pieces.
- Control panel (CP) - 1 piece.
- Remote post (RP) - 10 pieces.
Note: possible separate delivery of power amplifier, control panel or remote post.
