Eight pianos are only part of an eight-station lab. The room also needs places for eight people to sit, routes for cables, a way for the teacher to hear a student, and somewhere to put equipment that has failed. Those decisions belong in the first quote.
This worksheet plans eight student stations plus a separate teacher station. It assumes an existing room and teacher piano. The teaching goal is one beginner at each 88-key instrument, using wired listening.
Before ordering: measure the room with seats occupied, choose walk-around or central teacher monitoring, and have the institution's facilities/accessibility staff review the layout. No tablets or software subscription are required for basic individual playing. The plan below is hypothetical and not to scale.
Lay out the people before ordering the pianos
Start with paper outlines or temporary floor markers for the complete station: instrument, support, seat, player's legs and pedal. Then sit someone at each proposed position. Check the teacher's view of hands and the route to the back row with coats and bags put away.
This sketch uses two banks of four students, all looking towards the teaching end. It leaves a central route and keeps storage away from that route. Actual doors, pillars, exits and accessible work positions may require a different arrangement.
Separate instrument and seat
Instrument depth is a particularly misleading shortcut. The piano might be less than a foot deep, while the player, seat and approach need considerably more room. A stand can also block knee space even when its overall width looks generous.
In the US, the Access Board’s accessible-route guide describes a generally 36-inch minimum clear route, with further requirements at turns and other locations. That number alone does not approve a classroom. Ask the local reviewer to check door manoeuvring, turning space, usable station access and emergency egress under the rules that apply to your site.
Specify one complete student station
An 88-key hammer-action piano is a sensible basis when the course teaches piano technique and repertoire. For a room primarily teaching sequencing or production, a different keyboard specification may be justified. Write down the curriculum first so the supplier knows which compromises are acceptable.
The Yamaha P-145BT is a compact example to measure, rather than a claim that every school should buy this model. Its single headphone output also makes the listening arrangement worth settling before a bulk purchase.

Yamaha’s specification gives a bare-instrument width of 1,326 mm and depth of 268 mm, or 320 mm deep with the music rest. It has one standard stereo headphone jack and no separate AUX OUT. The listed L-100 stand is a separate purchase. Confirm the regional package includes the recommended power adapter, music rest and footswitch.
For each station, record the exact stand model and fixing method, adjustable seating that fits the students, reachable pedal placement, and a wired headset or headphones with the correct plug. A two-person lesson using one piano raises a different connection problem; our splitter and headphone-amp guide covers that case.
Try one complete station with representative users before buying eight. Check the lowest and highest seat positions, control reach, cable strain and whether a student can enter and leave without moving a neighbouring instrument. No published key-action specification establishes that fit.
Choose what the teacher needs to hear
Walk-around listening is the simpler starting point. Each student hears their own instrument through headphones. The teacher visits a station and uses a planned local listening arrangement, or asks for a short speaker demonstration while the others pause. Ordinary headphone connections do not give the teacher central selection, talkback or remote muting.
Separate connection: approved power supply → piano DC input.
Central monitoring becomes useful when the teacher needs to listen privately to any student, speak through a headset, or create audio groups without interrupting the room. Budget for a purpose-built system, its station interfaces and commissioning.
Yamaha's LC4 Base is documented for eight students and one teacher. Its installation guide, PDF routes each instrument's headphone output into a local instrument box, the headset into that box, and the box back to the lab hub. The listed base package includes nine instrument boxes and headsets.
Lab connection: instrument box → designated hub station port → teacher control.
Those RJ45 lab cables go to the system's specified ports. Do not assume that a familiar connector makes them ordinary school-network connections. Ask the supplier to demonstrate your exact piano, headset, levels and speaker-muting behaviour together. The P-145BT and LC4 combination has not been tested for this post.
Yamaha's MLC-200 page currently flags delivery delays and directs buyers to the LC4 alternative. Obtain a current supply date and support statement for either system. An old catalogue price or an app still appearing in a store does not establish that the full installation can be supplied.
Give facilities a power plan and purchasing worksheet
List the power requirements from each device's actual label, including the teacher station, hub, computer and any display. Have a qualified person specify outlets, circuits and cable containment. Keep mains and audio runs identifiable and protected from feet, moving seats and pulled connectors.
Do not join power strips together. OSHA’s power-strip guidance discusses listed devices being connected directly to a permanent receptacle rather than another strip or an extension lead. Follow the equipment instructions and your institution's local electrical rules; eight low-power pianos still need a properly planned installation.
Use the worksheet below for a dated supplier quote. The one filled figure is a US retail reference checked 27 September 2026: Sweetwater listed the P-145BT at US$529.99, making eight instruments US$4,239.92 before tax and shipping. This is separate from the changing Amazon card price and is not a school-volume quote or a complete lab total.
| Line item | Quantity / scope | Extended quote, USD |
|---|---|---|
| Student pianos | 8, with confirmed supplied accessories | 4,239.92 retail reference |
| Supports + seats | 8 compatible stands and 8 suitable seats | _____ |
| Listening | 8 headphones, OR complete 8-student + teacher lab package; avoid duplicate headsets | _____ |
| Teacher position | Existing piano/seat assumed; price any missing interface or support | _____ |
| Room works | Power, containment, accessibility changes, installation and commissioning | _____ |
| Storage + spares | Secure storage, labels, cleaning supplies, selected spare pedal/headphones | _____ |
| Delivery + tax | Freight, assembly and applicable local tax | _____ |
| Completed setup | Add every required line after the site review | Not yet priced |
Keep annual maintenance, software or support subscriptions on a separate recurring-cost line. Basic headphone playing does not need a subscription; optional teaching software and supplier service arrangements may add one. For a longer approval horizon, use a three-year software budget alongside the hardware quote.
Hand over a room that staff can operate
Nominate an equipment owner and a deputy. Keep the station diagram, adapter models, serial numbers, reset settings and supplier contact in a staff folder. Assign a place for faulty equipment so it cannot quietly return to the next class.
- All eight occupied: check movement, sightlines, seats and cable clearance in the actual room.
- Every listening position: start at low volume, play both channels, test the pedal, and check any teacher selection, talkback and group functions.
- Between classes: demonstrate the reset, headphone storage and manufacturer-approved cleaning routine. Listen to the room below too; headphones leave key and pedal impact noise untouched.
- One station unavailable: rehearse the backup arrangement and how staff record and report a fault.
For the practice students take outside this room, Practis for institutions can give staff context from practice logs and preparation across a programme. It is separate from the lab's audio-routing equipment.
Sign off the equipment list only after the teacher and facilities reviewer have walked the installed room together. Retain their final station numbering and connection record where a substitute teacher can find them.
