Portable Line-In-The Hole Devices and What They Can Achieve
Portable Line-In-The Hole devices, also known as PTH devices, are great for indoor or outdoor use. This is an excellent choice for public safety events, large venues such as concerts, sporting events, and parades, and even for security and perimeter fencing requirements at businesses, offices, and other facilities. A PTH enclosure protects the device and the user by filtering unwanted noise or even transmitting live feeds to the control room.
These devices are often used for entertainment in the area where the sound can be blocked by walls or other obstacles. The benefits of these devices are the ease of installation and the wide variety of uses they offer. PTHs can be constructed in minutes with no complicated wiring or coordination with utility lines. This makes them perfect for off-site applications.
These devices are also perfect for public safety events. When not being used for entertainment, they provide a fail-safe barrier to protect people from harm, especially when concert-goers are crowded together around a sound device. Some models are fully adjustable and can accommodate different sized crowds. The speakers themselves are also lightweight and compact, which makes them easy to transport. Even a small stand with the speakers can make for a convenient way to carry the device from one location to another.
Portable line-in-the-hole devices come in a variety of sizes. Some can accommodate two line options at once, while others are capable of supporting up to four devices. Some are even capable of supporting wireless connections, like those that are used for wireless PA systems at concerts and meetings. Others are limited to one line of stimulation, while others are set up to handle up to twelve sources. Like their wired counterparts, some devices have a microphone built into them so users can easily integrate the device into any existing PA system.
The size of a given device is important, though. Since each device is intended to handle a specific source and sound, it's important to make sure the device is appropriate for the space where it will be used. Certain devices will only work if there is a direct connection to the source, while others may need to go through an intermediary gateway. This can make it difficult to get sound to certain areas of the venue and limit what can be heard at other times.
Portable devices are also more expensive than their fixed counterparts. While the initial purchase price is higher overall, this expense is offset by the potential cost savings over the life of the product. Some devices last for up to three years and can save hundreds of dollars off the cost of long-term contracts. There is also the advantage that the devices can be moved around as needed, saving venues the expense of renting or leasing facilities.
A major consideration for many venues when choosing portable line-in-the-hole devices is noise reduction. Some devices are designed to reduce outside noise while others are meant to eliminate the sounds of passing traffic. It is important to look at the overall level of outside noise before making a selection. Some of the newer generation devices offer the ability to isolate specific areas of the room or area to reduce background noise. For large events, it is important to choose devices that will offer the greatest reduction in outside noise.
Portable devices can be a great tool for helping to control sound levels in an environment. However, it is essential to consider the device's operation and care before using it. Devices should be maintained properly and not neglected for extended periods of time. Devices that are not maintained can malfunction and create the undesirable sound conditions. By using the devices properly and regularly, sound levels can be effectively reduced and safety can be enhanced.
