PA System M/S Amplifier Switch RH2821M

※ Connect to 5 main  amplifiers and 1 spare amplifier.
※ Automatic detection of fault units,and the first fault detected unit will be   
automatically switched to the spare unit,other fault units if later detected  
will be brought to your attention by the indicators.
※ Prompt tone will ring should any main unit fails.
※ Indicators have three different indications:Normal,Fault,or Spare.
※ Address setting using decimal system.
Description
The Main/Spare Amplifier Switch RH2821M monitors up to five main amplifiers in the pa system,RH2821Mwhich will be switched automatically to the spare amplifier should any one fails,with five independent channels, it can also be operated manually for power switching amplifier upgrades and maintenance, each channel has a volume control, manual switch,and status indicator.
Note:
• Only one main amplifier is used in above connection,the Main/Spare Amplifier Switch RH2821M can support connecting five main amplifiers in the same time.
• Make sure the terminals of  "+" and "COM" are connected correctly to match each other between the devices.

16 Zone Speaker Selector RH2813AM

Image
The RH AUDIO   16 zone speaker selector switch RH2813AM has 4 channel inputs (A1,A2,A3,A4) of amplified signal for BGM,with 4 channel inputs (B1,B2,B3,B4) of amplified signal for paging,and 16 individual relay switches,allows the user to distribute an amplified speaker signal up to 16 listening zones. Paging signal from the remote microphone console RH2816RT enjoys auto-muting facilitates announcements overriding the BGM signal with a quick return to regular operation at any time once the paging stops. The 25-pin alarm input bus is ready to receive the EMC. S ignal from its counterpart 10 zone paging selector RH2816PT,   and this input has top priority over paging and BGM signal to support system to output a siren signal or a user-recorded voice alarm or siren once any emergency occurs in the venue. Built-in monitor speaker with volume control on front panel offers cost effective solution without needing to add separate monitor device in the pa system. T...

Application Principle of Best Column Speakers

Image
  The  best column speakers  is composed of several speakers arranged and connected together. The directional characteristic of the best column speakers is similar to that of a single speaker in the horizontal direction, but greatly improved in the vertical direction. It propagates in wave form in horizontal direction, but has strong directional characteristics in vertical direction, forming a "dish" shaped stereo radiation effect. Install the best column speakers near the stage entrance, point the "sound disc" to the audience, radiate the sound beam to the back of the auditorium with strong sound energy, while the front row weakens each other due to the phase difference caused by the different vertical distance of the speaker, which may be lower than the sound pressure of a single speaker, which makes the distribution of direct sound field tend to be uniform. The horizontal direction of the speaker column should not be "bunching", but should have a larger...

What is the Two Channel 100V Aplifie？

Image
  Many people misunderstand it as a stereo system because there are two channels, and the stereo mixer is connected to the system before the stereo amplifier and equalizer are used in the whole system. However, what these systems lack is the uniform coverage of the whole auditory area, as well as the minimal difference in sound pressure level and phase response of each channel to the coverage of the auditory area. If the  two channel 100V amplifie  system plays stereo signals without providing smooth overlapping coverage, half of the people in the listening area can only hear half of the audio content, which makes the dual-channel system a bad choice for music amplification. Most listeners hear a completely different mix of music from others. This is too common an oversight in venues for music and entertainment purposes, even in high-quality venues that should have better system design. It is a common misunderstanding for people with working background of tour or live aud...
