Listening simulations are established.
AFMG EASE includes auralisation. FieldKast puts a simpler listening estimate in the outdoor site planner, alongside the radio and timing plan.
Choose the right signal path
Compare the
whole job.
Getting audio to a speaker is one task. Timing it, placing it and knowing it is still playing are the rest. Compare the full system, including the work around the radio link.
| What the job needs | FieldKast | Wired + DSP | Silent-disco-style UHF | Professional wireless | FM radio |
|---|---|---|---|---|---|
| Long audio cable runs | None between FOH and positions | Required; route and protect crossings | Not required | Not required | Not required |
| Individual speaker delay | Built into each receiver | Desk / external DSP / speaker DSP | Usually separate DSP; check the receiver | Built in on some systems | Separate DSP needed |
| Stage alignment workflow | Map → actual positions → delay file | Design and measure; apply via chosen DSP | Design and DSP configured separately | Product-specific; check controls | Design and DSP configured separately |
| Prevent unauthorised programme audio | Authenticated audio and commands | Physical access to signal path matters | Do not assume cryptographic authentication | Encrypted products exist; verify model | Ordinary broadcast reception is not authenticated |
| Radio site planning | 2.4 GHz; survey crowds and interference | No RF link for audio | Band / channel dependent | Band / channel dependent | Spectrum permission and reception must be checked |
| Where it makes sense | Open-site delay speakers, beyond latency limit | RF-heavy sites and short direct runs | Headphones and simple distribution | Specialist links with the required specification | Broadcast reception; not a turnkey aligned PA |
Category comparison, reviewed 9 October 2026. Individual products differ. “Separate DSP” may be provided by a compatible active speaker or desk, rather than a separate box. Compare the exact model, legal band, range, output level and delay capacity.
What is genuinely different?
The joined-up workflow.
Not an “only one” claim.
FieldKast brings open-site layout, listening estimates, guided placement, real-position delay calculation and receiver control into one workflow with your existing speakers.
Wireless delay is established.
Alto Stealth Pro advertises built-in delay. Neutrik XIRIUM PRO documents app-controlled delay and mute. Delay alone is not a unique FieldKast claim.
Guided setup is established.
d&b ArrayCalc Viewer provides deployment and positioning information. FieldKast’s documented workflow connects phone placement, receiver identity and actual positions back to its delay plan.
The reviewed sources do not establish worldwide exclusivity for the combined workflow. FieldKast is presented on its documented benefits, not as the first or only system.
Look beyond the transmitter price
Price the system.
Count the work.
For a fair comparison, hold the speakers and tripods constant. Include enough independent delay channels, the cable route and protection, power, survey and crew time.
Some active speakers already have useful delay DSP. Check their maximum delay before budgeting for extra boxes.

Illustrative straight-line cable quantity only; no routing allowance. This is not a priced competitor quotation or a guaranteed saving. Local audio leads and power are still needed with FieldKast.
