Audio Solutions Question of the Week: How Can I Run Audio Wirelessly From Two Locations Without AC Power?

Question: How can I run audio wirelessly from two locations without AC power?

Answer: There are environments where you may not be able to use the ideal setup. This may be a historic building where you cannot drill into the walls to run cables or an area where a cable would run alongside a power or video line (while most cables have enough shielding, the proximity could potentially cause issues with the signal). Thinking “outside the box,” you can use existing products to create solutions for these less-than-ideal situations. For example, say you need to run audio from a battery-powered PTZ (pan-tilt-zoom) camera to a remote portable audio system in a historic building. The previous installation had analog video coax cables running to an older camera system. However, when the system upgrade project received funding and the “green light,” there was no way to change the cables and upgrade the cameras to add audio. Using the Audio-Technica 3000 Series 4th generation wireless alongside the 3000 Series IEM wireless components provides a solution.

The compatibility of the 3000 Series wireless system and the 3000 Series IEM components allows you to use the AC-powered transmitter and AC-powered receiver together or use the battery-powered transmitter and battery-powered receiver together. For the problem outlined above, you can use the battery-powered ATW-T3201 body-pack transmitter from the 3000 Series wireless system and the battery-powered ATW-R3250 receiver from the 3000 Series IEM. The components, if tuned to the same coordinated frequency, share the same pilot tone and can pass the audio from the camera’s audio output to the building’s battery-powered sound system. When the system is in use, the low-profile, battery-powered transmitter and receiver can be set up to connect the audio.

In applications where a permanent installation is required, using AC-powered components would be optimal. The setup, otherwise, would be the same, with both transmitter and receiver set to the same coordinated frequency so they can pass the audio.
