If your event covers a lot of ground—or needs to stay tidy and trip-free—a wireless PA system is a game-changer. At AVE Services we pair JTS wireless TX/RX packs with battery speakers (including the EV EVERSE 8). The RX can be powered from the speaker’s DC out, so we don’t need a single mains run or XLR signal cable. That means we can drop speakers exactly where they’re needed—even in the middle of a field—and get full coverage with clean sightlines and fast setup.
Below, we break down the benefits, the tech behind it, and real-world use cases like graduations, memorial relay feeds, sports days, and more.
Why go cable-free?
1) Faster setup & pack-down
No mains cable. No 50-metre XLRs. Fewer cable mats. A small crew can cover large sites quickly, which is ideal for tight turnarounds or venues with limited access.
2) Safer and cleaner sites
Removing long cable runs cuts slip hazards and keeps routes clear for guests, processions, or athletes. It also keeps your photos and video looking tidy.
3) True layout freedom
Battery speakers with wireless audio can go anywhere—grandstands, tree lines, overflow lawns—without hunting for power. You get coverage where people actually are.
4) Reliable long-range audio
JTS wireless TX/RX systems are designed for extended range with robust RF. Used correctly (sensible antenna placement and frequency management), you get consistent wireless audio without the “will the cable reach?” worry.
5) Built-in power for the receiver
With speakers like the EV EVERSE 8, the DC power out can feed the wireless RX. One battery powers both loudspeaker and receiver, reducing gear count and failure points.
6) Scalable for big crowds
Need to cover a quad, a sports field, or a procession route? Add speakers where needed and link them into the same program feed. You can scale from a handful of units to dozens.
Time-alignment (delay) for pro results
Sound travels at roughly 343 m/s (≈ 2.9 ms per metre). If your front-of-house and outfield speakers both play the same signal at the same time, distant boxes will sound late and smeary.
Per-speaker delay fixes this. We add digital delay on each outfield unit so the audio arrives in sync with the main source.
-
Rule of thumb: add ~2.9 ms of delay for every 1 metre the outfield speaker is behind the main reference point.
-
Example: if a satellite speaker sits 30 m behind the stage, set ≈ 87 ms delay.
This keeps speech crisp for graduation names, wedding vows, and memorial readings—where intelligibility really matters.
Event scenarios where wireless battery speakers shine
Graduation ceremonies (and overflow/relay areas)
-
Spread compact speakers along seating rows and overflow lawns.
-
Use relay positions outside the main arena for latecomers or families with prams.
-
Add per-zone delay so each cluster feels “local” and clear.
Funeral & wedding relays / memorials
-
Quiet, discreet placement—no generators or taped-down snakes.
-
Quick repositioning if the procession route changes.
-
Low visual impact for sensitive spaces.
School sports days
-
Cover multiple lanes or pitches without crossing the track with cable.
-
Move speakers between heats or events in minutes.
-
Announcements remain intelligible across the site.
Community fêtes, fairs, charity runs
-
Pop-up PA for start/finish lines, stalls, and info points.
-
Battery operation avoids overloading temporary power.
Corporate away days & outdoor briefings
-
Rapid deployment for morning briefings; re-position for breakouts.
-
Consistent audio without venue power logistics.
Practical tips for reliable wireless audio
-
Site scan & frequency plan: Avoid local RF congestion; set intermod-safe channel spacing.
-
Antenna discipline: Keep RX antennas elevated and line-of-sight to TX where possible.
-
Gain structure: Set healthy input gain on TX; leave headroom to prevent limiting.
-
Battery management: Top up all speaker and RX/TX batteries; rotate spares on a schedule.
-
Weather plan: Use rain covers/shower caps; elevate off damp ground.
-
Label zones: Colour-code speakers (A/B/C) and match to delay settings for quick checks.
-
Test & walk the field: Play speech and walk coverage lines before gates open.
Example “drop-and-go” kit list
-
Program source (lectern mic + playback)
-
JTS wireless TX on the mixer output (or a dedicated send)
-
Multiple battery speakers (e.g., EV EVERSE 8), each with:
-
JTS wireless RX powered from DC out
- Per-speaker delay configured to match placement
-
Spares: charged batteries, antennas, tape, rain covers
FAQ
In most outdoor layouts, yes—with correct frequency planning and antenna placement. We’ll survey your site and specify TX power and antenna options to match.
We use speech-first EQ and sensible SPL targets so announcements cut through without being harsh.
For speech-led events—graduation, memorial relay, sports days—it’s ideal. For bands or very high SPL, we can blend battery satellites with a main system.
Yes. We can split the program feed for recording/streaming while the wireless chain handles PA coverage.
