Serving Audiences of Any Size
When you want to play music or address an audience without shouting, turning to an amplification system is the logical thing to do. With so many different sizes and types to choose from, it can be a bit daunting knowing which one will do the job best. But then again, why stop at just one? Part of successfully amplifying sound has to do with ensuring that your collective audience can hear what is being emitted. But with just one portable speaker, regardless of the setting, usually those sitting closest to the speaker benefit the most. However, if you manage to incorporate multiple speakers throughout the environment, then all of your listeners will be fully focused on your presentation. You no longer have to choose between portable speakers, simply use them all!
In an age where devices are more hi-tech and wireless, portable audio speakers provide the flexibility of projecting audio to audiences of varying sizes using multiple units. Though you can connect a number of speakers through the line out function (and this feature usually isn’t married to using any single manufacturer’s speakers), it’s often more convenient and faster to eliminate wires all together. If this sounds appealing, there are a couple of ways to accomplish this.
If you’re considering purchasing your first portable (and wireless) PA and can envision an instance in the future when you’d like to use more than one PA at an event, make sure the wireless PA (or its microphone) can be used with other PA gear. Not all PA gear offers this kind of redundancy. Buying a dedicated mic for each PA becomes not only expensive, but can create inventory problems. The entire line of Califone UHF equipment works on the same set of 16 channels to ensure that each UHF speaker (and microphone) can communicate with each other.
Sends the audio signal to an unlimited number of powered support speakers for broader audience coverage.
The first way to have multiple PAs send out your voice would be to simply set them to the same frequency to receive the signal from the wireless mic. The range of transmission is determined by the mic itself, which for either the Califone handheld wireless mic (Q319) or the beltpack transmitter (M319), is about 150’. While this can be quickly achieved, it doesn’t give you much control of the “system” since each PA is operating independently of each other. You can however adjust the volume separately for each with the included “Volume/Mute” control.
The second method gives you the ability to wirelessly daisy-chain the speakers together, enabling you to control however many speakers you have in the “system”, while providing your audience with maximum sound quality. This scenario is made possible by the wireless transmission ability from the PA919, or the PA919SD to any other Califone UHF PA. With their 300’ transmission range, these speakers give you the ability to position multiple speakers farther apart, thereby surrounding the audience so that everyone can not only watch but also listen to you.
To accomplish this, you’ll need to first set the frequency on each receiving (or “companion”) PA to the same channel just as you would for transmitting from a wireless mic to a PA. The only difference now is instead of receiving the signal from a wireless mic, these companion PAs are getting their signal from the “master” PA (the PA919 or PA919SD). So the wireless mic sends its signal to the wireless mic receiver on the master PA, which then transmits your voice out to the receiving companion PAs but on a different frequency. What’s occurring is there are two different wireless channels being used – one for the signal from the wireless mic to the master PA and another from the master PA to all of the receiving companion PAs.
By following this second method, you can take advantage of many of the features on the master PA as explained in our “How To” series. So no matter what physical setting or scenario you find yourself in, you will feel at ease knowing you’ve captivated not only their hearing but their attention as well.
