Wireless Microphone Tech Rider: RF, Channels, and Coordination

TL;DR — A wireless microphone tech rider should identify every transmitter and receiver, device role, manufacturer and model, tuning band, audio output, performer assignment, supplier, antenna plan, battery method, and backup path. Treat wireless microphones and IEMs as one RF inventory, but keep their audio destinations distinct. Do not publish fixed show frequencies as a touring promise: the responsible technician should coordinate legal, compatible frequencies for the actual location and RF environment.

Build one wireless inventory

Start with every device that transmits RF in or near the production. Wireless vocal microphones are only part of the picture. Bodypacks, instrument systems, wireless intercom, and IEM transmitters can all affect the coordination plan.

Create one row per active RF channel and record:

• a stable channel ID and purpose;
• performer or crew assignment;
• transmitter type, manufacturer, and model;
• receiver or IEM system manufacturer and model;
• tuning band or supported frequency range exactly as marked on the equipment;
• who supplies the system;
• where the receiver or transmitter rack will sit;
• audio connector and destination;
• antenna connection or distribution notes;
• battery type and change responsibility;
• primary and spare hardware.

Do not write only 4 wireless mics. Two systems with similar-looking handhelds may tune in different bands or require different coordination data. Inventory the equipment that will actually arrive.

Use names that remain stable from rehearsal to show day, such as RF-MIC-01 — Lead vocal or RF-IEM-03 — Drums. A performer name can change; the system ID should not.

Separate RF details from audio channels

The RF channel and the console input are related, but they are not the same thing. One describes the radio link; the other describes where audio enters or leaves the sound system.

Wireless microphone example

Wireless IEM example

Replace every placeholder with the exact carried or confirmed venue system. If equipment is venue-provided, state the functional requirement and acceptable alternatives, then confirm the final model and band during the advance.

On the stage plot, show performer positions, receiver or transmitter racks when their placement matters, antenna locations, and the audio handoff. Keep detailed serial numbers, tuning ranges, and battery notes in the rider table so the drawing stays readable.

For wired and wireless vocal channel naming, see Vocal Microphone Stage Plot. For IEM destinations and mix formats, use Configuring Monitor Mixes & IEMs.

Document coordination responsibility

Frequency coordination is the process of selecting frequencies that are permitted at the location, clear enough to use, and compatible with the other wireless systems in the production. The final plan depends on location, local spectrum use, nearby productions, equipment bands, and the systems operating together.

Before the show

Send the complete inventory to the venue or festival RF contact. Include the city and venue, show date, equipment bands, requested active channels, spares, and any system that cannot be retuned. Ask who owns the master coordination.

Do not independently assign a touring frequency list when a festival or venue has an RF coordinator. They need visibility across every act, intercom system, house device, and IEM channel.

On site

The responsible technician should verify the RF environment, calculate or select a compatible set, program the equipment, label assignments, and test all primary and backup systems. A scan is useful input to coordination, but scanning for an apparently open frequency is not the whole process when several systems operate together.

What belongs in the rider

Write the coordination workflow, not an unqualified promise that one frequency will work everywhere:

Artist carries six retunable wireless channels in the bands listed below. Venue or festival RF coordinator assigns final frequencies. Artist provides the complete inventory by the advance deadline and will not power RF transmitters until cleared on site.

If a frequency is fixed or a device has limited tuning, flag that constraint prominently. Local spectrum rules vary, so the responsible production professional must verify lawful operation for each location.

Add antennas, power, and batteries

Antennas and rack position

Record whether the system uses receiver antennas, remote antennas, antenna distribution, or a combined IEM transmit path. Show the planned rack and antenna locations when stage geometry, cable distance, or line of sight affects deployment.

Do not invent antenna spacing, amplifier gain, cable-loss compensation, or transmit power in a generic rider. Those settings depend on the actual hardware and system design. Provide the inventory and physical requirement, then let the qualified technician approve the deployment.

Audio and network connections

List the receiver audio outputs and IEM transmitter inputs, including connector type and whether the artist or venue supplies the cables. If control or monitoring uses a local network, identify the artist-carried switch, computer, and cabling. Do not assume access to public Wi-Fi or a venue production network.

Power

Mark the rack power location on the stage plot and document the equipment's rated requirements. The venue's qualified staff decide final electrical distribution. Keep the wireless rack on the same production power plan as the rest of the carried audio equipment.

Batteries

State the approved battery type, who supplies it, when batteries are changed, how rechargeable packs are charged, and how state of charge is verified. Label fresh, used, charging, and failed batteries so a rushed change does not return a depleted pack to service.

Plan spares and failure response

A spare is useful only if the crew knows what it replaces and how it enters the coordinated plan.

Document:

• which transmitters, bodypacks, capsules, lavaliers, headsets, and cables have spares;
• whether a spare receiver channel is available;
• which backup frequencies are included in the coordination;
• where spare batteries and hardware are kept;
• who can authorize and perform a swap;
• whether the fallback is another wireless system or a wired microphone;
• how FOH and monitors will identify the replacement source.

Do not power a spare transmitter on the same assigned frequency while the primary transmitter is active. A receiver can only use the intended transmitter on that frequency; two active transmitters create a conflict, not redundancy.

Rehearse the simplest likely change: mute the affected audio path, replace or switch the approved device, confirm the assignment, restore audio, and report the change to the relevant engineers.

Advance the wireless package

Send the wireless section with the current rider and resolve these points:

1. master RF coordinator and contact;
2. inventory submission deadline and file format;
3. exact active microphone, instrument, IEM, and intercom channel counts;
4. manufacturer, model, tuning band, and supplier for every system;
5. systems that cannot be retuned;
6. receiver, transmitter, rack, and antenna locations;
7. audio handoffs, console channels, and monitor destinations;
8. battery supply, charging, and change responsibility;
9. primary, spare, and wired fallback paths;
10. time for coordination, programming, walk testing, line check, and soundcheck.

Update the rider after the advance. If the tour manager, production manager, or engineer owns part of the information, invite them to edit and save the same Rider and inspect its history. Export a dated PDF for the show-day package while keeping the current link available to the production team.

Common wireless-rider mistakes

Listing only the number of wireless channels. Include exact device models, tuning bands, assignments, ownership, and audio connections.

Treating microphones and IEMs as separate RF worlds. Coordinate every system operating in the same production environment.

Publishing one frequency list for an entire tour. Final legal and compatible assignments depend on the actual location and RF environment.

Powering transmitters before clearance. Follow the venue or festival coordinator's process.

Confusing RF assignments with console channels. Link the radio system to its audio input or output without merging the two identifiers.

Calling an unprogrammed spare a backup. Include spare hardware and frequencies in the plan before the show.

Pre-send checklist

• Every active wireless system has one RF inventory row.
• Manufacturer, model, tuning band, assignment, and supplier are stated.
• Wireless microphones, instruments, IEMs, and intercom are included.
• Audio handoffs match the input list and monitor plan.
• Rack and antenna locations appear where relevant.
• The master coordination owner and deadline are named.
• Fixed or limited-tuning equipment is flagged.
• Battery supply, charging, and change responsibility are clear.
• Spares and wired fallbacks have an approved activation path.
• The final rider reflects the production advance.

FAQ

What should a wireless microphone tech rider include?

Include every transmitter and receiver, stable RF ID, performer assignment, manufacturer and model, tuning band, supplier, audio handoff, console channel or monitor destination, rack and antenna location, battery process, coordination owner, and backup path.

How do you coordinate wireless microphone frequencies?

Collect the complete equipment inventory, assess the location and RF environment, account for every system operating together, calculate or select legal compatible frequencies, program and label the devices, then test primary and backup assignments on site. Complex productions should use a qualified RF coordinator.

Should wireless frequencies be listed in a tech rider?

List final frequencies when they have been assigned for that specific show, but do not present one touring frequency list as universally valid. Before coordination, list equipment bands, constraints, channel counts, and the person responsible for final assignments.

Who coordinates wireless microphones at a venue?

The venue or festival may appoint an RF coordinator; otherwise the advance must assign responsibility to a qualified artist or venue technician. One person or team needs authority over the combined wireless inventory.

How do you make a wireless microphone input list?

Give each receiver output a console-channel row with the same stable source name used in the RF inventory. Record the microphone role, receiver output, connector, supplier, and monitor destinations. Keep frequency and tuning-band data in linked RF fields rather than replacing the audio channel information.

Keep the RF and audio plans connected

Create the wireless stage plot and input list in Techrider.live, keep every source name consistent, invite the responsible engineer to edit the same Rider, and send the current link before coordination begins.
