CMD-6104(IR TRANSMISSION MASTER)

Core Technique:

1.BAND2 frequency range, avoid the disturbance of daylight
2.Frequency modulation technology, guarantee its sound quality
3.Auto gain control technology,
4.Phase-locked loop technology, with accurate frequency and non-error
5.Double output BNC interface, easy for project installation

Function Description:

1.Wireless transmission and high security to prevent hostile disturbance and monitor.
2.Auto level control function (ALC)
3.Due to higher transmission frequency (2M-6MHz),receiver owns super anti-interference ability without ray disturbance of high frequency driver. 4.Phase-locked loop technology, with stable radiation frequency.
5.With 6 groups outer audio input channels, can input outer audio or sound signal
6.With 6 groups language output channels, can output 6 interpreted language at most to monitor or record. 7.Particular testing function of the master, can produce 12 audio modulating signals of different frequency for convenient system debugging.
8.With input level testing function, LED of the master's front panel can display the capacity of input level.
9.With alarm function, can send out emergency information to all audio channels automatically.
10.With groups original language channel output, can connect with PA amplifier to send out the enlarged speech and also can connect cassette to record.
11.Input voltage is AC 100-240V,with AC output socket (unnecessary to pass system's switch)，pass the high pressure-resistance(3500V)test before selling, and make sure up to standard security.
12.The cover of master is made by metal material, both cables and covers all strengthen the connection with earth wire, to make sure its capacity of preventing 8000V static electricity.
