How to Plan Audio Zones for a 100-Room Hotel: A Floor-Plan Walkthrough

If you're planning audio for a 100-room hotel and have ever found yourself staring at a floor plan thinking "where do I even start with zones" — this guide is the answer. We walk through the methodology used by integrators on real properties: how to identify zones, how to count them, how to name them, and what common decisions cause problems six months after install.

The guide is vendor-neutral. Rafilis makes Rafilis Multizone, a Windows-based multi-zone audio platform used in hotels — but the planning method below applies regardless of which software or DSP you use.

For broader context on hotel music systems generally, our complete guide to hotel background music systems covers the strategic and budgetary layer. This article goes a step deeper into the actual physical/zone mapping.

Step 1 — Print the floor plan

Real walls, real doors, real distances. Get the architectural floor plan (every floor, including basement and rooftop if applicable), printed at a size you can mark up — A3 is usually right, A4 only for very small properties.

If the floor plan is digital, print it. Marking it digitally is fine in theory but adds friction. Operations leads, F&B managers, and AV integrators all need to mark and discuss simultaneously; paper is faster.

Step 2 — Walk the property with the floor plan

Don't skip this. You need to be physically in each space to identify acoustic boundaries that aren't on the architectural drawing.

Specifically, you're looking for:

• Open doorways between two distinct areas (often missed on plans)
• Wall cutouts, half-walls, planters that look like dividers on paper but acoustically aren't
• Glass walls that visually divide but acoustically don't
• Mezzanine spaces where audio bleeds vertically
• Open staircases between floors
• Outdoor / indoor transitions with sliding glass doors

For each area, listen. Stand still. Can you hear from one area into another even with no music currently playing? If a casual conversation in Area A would be audible in Area B, music in A will be audible in B too. They're the same acoustic zone whether you like it or not.

Step 3 — Identify the candidate zones

Start by listing every distinct guest-facing space. For a 100-room hotel, this is typically:

1. Entrance lobby + reception
2. Lobby lounge / seating area
3. Concierge / club lounge (if separate)
4. Main restaurant
5. Breakfast room (if separate)
6. À la carte / specialty restaurant (if separate)
7. Bar / lounge
8. Pool bar / outdoor bar
9. Function rooms / conference rooms (each counted separately)
10. Spa / wellness suite
11. Fitness centre
12. Indoor pool area
13. Outdoor pool / terrace
14. Corridors / lifts (combined)
15. Back-of-house (kitchens, staff areas — combined)

This is the candidate list. Some entries will collapse into others during the next step.

Step 4 — Apply the acoustic boundary test

For each adjacent pair on your candidate list, ask: is there a physical boundary that prevents audio bleed?

If two adjacent spaces fail the test, merge them into one zone. The system can't make them sound different if guests will hear both anyway.

Step 5 — Identify the schedule-only splits

Some zones look acoustically merged but operationally separate. The classic case:

The hotel lobby and bar are open to each other. Acoustically one zone. But the bar plays cocktail music from 18:00 while the lobby plays ambient all day.

You have a problem. If you treat them as one zone, you can't play different music in them at the same time. If you treat them as two zones, the music bleeds.

Three solutions, in increasing cost:

1. Treat as one zone with a unified schedule: at 18:00, both lobby + bar swap to cocktail. This is the cheapest and most common solution in practice. Acoustically honest.

1. Add an acoustic separation: a glass partition with a door, retractable curtain, or moveable wall. Then they're two zones from 18:00 onwards. Significant capex.

1. Use very directional speakers in the bar (pendant speakers pointed straight down at a low volume) so the bar music doesn't actually bleed to the lobby. Marginal — works in some layouts, not all.

The 100-room hotel almost always chooses option 1 for cost reasons. That's fine. You're not failing — you're making an honest acoustic call.

Step 6 — Count speakers per zone

Once your zones are finalised, count the speakers each will need. Rough rules:

• Ceiling speakers at standard 2.7–3.5m ceiling heights cover roughly a 4–5m diameter circle each at conversational SPL.
• Pendant speakers for double-height lobbies cover larger areas but need more careful placement.
• In-wall speakers for restaurants are usually paired (left/right) per dining area.
• Outdoor weatherproof speakers cover smaller areas due to higher SPL requirement to overcome ambient noise.

For each zone, calculate the floor area, divide by speaker coverage, and round up.

Example for a 100-room hotel:

Total physical speakers for this profile: ~70. Standard for a mid-tier 100-room property.

Step 7 — Name the zones

Sounds trivial, isn't. Six months in, when staff are trying to remember "is it Z3 or Zone-3?" or "which one was the Lobby again?", clear naming matters.

Bad naming:

• Zone 1, Zone 2, Zone 3 (numeric — staff have to memorise)
• "Lobby" (which lobby?)
• Generic names that don't match the architect's plan ("Restaurant" when there are three restaurants)

Good naming, with hotel context:

• "01-Lobby-Main"
• "02-Lobby-Lounge"
• "03-Restaurant-Aria" (using the venue's actual name)
• "04-Restaurant-Breakfast"
• "05-Bar-Aria"
• "10-Spa-Treatment"
• "11-Spa-Pool"
• "20-BoH-Staff" (back-of-house staff area)

The 2-digit prefix:

• Sorts zones alphabetically in any UI
• Lets staff refer to "zone 3" or "zone 11" verbally with no ambiguity
• Makes the 100-zone numbering scalable if the property expands

The descriptive part:

• Matches the architectural/marketing names that staff already know
• Includes the venue name where multiple similar zones exist ("Aria" restaurant vs "Marina" restaurant)
• Avoids initials only — "BR" could mean "ballroom" or "bar" or "breakfast"

Step 8 — Map to channels

For each zone, decide which physical audio interface channel(s) will drive it. This is where software architecture meets hardware reality.

If you're using a 16-channel USB audio interface (e.g., RME UFX III or similar), you have 16 output channels available. Assign them:

• Lobby Main → channels 1+2 (stereo)
• Lobby Lounge → channels 3+4 (stereo)
• Restaurant Aria → channels 5+6
• Bar → channels 7+8
• Spa → channel 9 (mono — guests aren't sitting in stereo sweetspot)
• Pool/outdoor → channels 10+11
• 3 × Conference rooms → channels 12, 13, 14 (mono each)
• BoH staff → channel 15
• Corridors → channel 16

Most properties under-utilise stereo. Mono is usually fine for background music in non-listening-focused spaces — and using mono per zone doubles your zone count for the same interface. Stereo matters in: dining-focused restaurants where guests sit still and listen, and high-end lounges/bars where music is a feature.

Step 9 — Document the zoning plan

Output of this exercise should be one document, ideally 2–4 pages, that captures:

1. Floor plan with zones outlined and labelled
2. Zone table (name, area, speaker count, channel assignment)
3. Schedule template (which playlist plays when in each zone)
4. Operational notes (who can change what, override rules)
5. Future expansion notes (where new zones could be added)

This document is the single source of truth that the AV integrator builds against. Without it, you get unexpected conversations 8 weeks in: "where do these wires go again?"

The four common assumptions to avoid

1. "We'll figure out zones during install." No, you won't. Cabling is destination-dependent. Wrong zone plan = wrong cable runs = expensive rework.

2. "The lobby and lounge are basically the same." Maybe to the AV integrator. To the F&B director, the lounge is where guests have cocktails at 17:00 and the lobby is where they check in at 14:00. Different schedules want different zones.

3. "We'll over-engineer with 20+ zones to be safe." 20 zones for a 100-room hotel means most are 80% similar to their neighbour. Operations becomes a maintenance burden. The right count is usually 8–14.

4. "The bedroom radios don't need to be a zone." Bedrooms are licensed (per-room PRS/PPL/ASCAP-BMI/GEMA fee) but operationally outside the multi-zone system. Don't include them as zones in the planning above — they're served by in-room TVs and don't sit on the central audio infrastructure.

How Rafilis Multizone helps with zone planning

The methodology above is independent of any software. That said, Rafilis Multizone is designed to support exactly this kind of zone planning:

• Each zone gets its own playlist, schedule, volume, and channel assignment
• The Multi-PC master-node architecture lets you split zones across multiple PCs in a large property without losing centralised control
• Zone planning documentation can map directly to zone configuration in the app — "01-Lobby-Main" on paper becomes "01-Lobby-Main" in the system

For larger hotels with 20+ zones spread across multiple physical locations, our multi-PC networking guide for resorts covers how to scale beyond a single PC.

Audio zone planning is one of those tasks that looks deceptively simple at the start of a project and becomes the single biggest source of regret if not done properly. An hour with a printed floor plan and a marker is the cheapest hour you'll spend on the entire audio install.
