The event
The Reformed Music Festival (RZF) is an annual festival organised by RKK — the Reformed Public Affairs and Cultural Foundation — at downtown Budapest venues, where Pantheon Sound has been the recurring audio production partner since 2023.
The festival does not run on a single stage: four parallel venues, four radically different sonic worlds — the stone-floored, long-reverberant interior of the Kálvin Square Reformed Church; the 300-seat galleried ceremonial hall of the Ráday House; the Kálvin Square outdoor street music programme; and an intimate outdoor jazz courtyard near Kálvin Square.

Pantheon Sound's role
Pantheon Sound delivers the full sound system design and implementation across all four parallel venues. The job is not four separate engagements but holding a consistent standard across four acoustically and stylistically very different spaces, within a single festival weekend — with one team and one organisational frame.
Each venue is designed on its own logic: the church's stone-floored, reverberant acoustic calls for directional coverage; the Ráday House ceremonial hall requires a full sound system buildup (with LED-wall content management included); on the Kálvin Square street music programme we provide vocal level support only — over the acoustic instruments; the jazz courtyard, by contrast, focuses on preserving the genre's intimacy.

Technical setup
Each venue runs on a separate system design, separate consoles and separate PA categories — every venue is built on its own acoustic and genre logic. The setup has been refined year by year since the 2023 first edition; the d&b PA configurations are powered by d&b D80 amplifiers, and the PS Audio CX systems run on Chevin amplifiers.
- Church — PA
- d&b E12 in 2023 (with d&b D80 amplifiers); PS Audio CX from 2024 (with Chevin amplifiers)
- Church — FOH
- Yamaha TF1 (all three years)
- Church — vocal microphones
- wired system for liturgical narration, providing a stable RF environment alongside the performers' own wireless rigs
- Church — organ
- reproduced acoustically, without reinforcement
- Ráday House — PA
- d&b E12 in 2023; d&b V7P + V Sub from 2024 — both configurations powered by d&b D80 amplifiers
- Ráday House — FOH

- Shure SLXD handheld and lavalier microphones, with antenna splitting and active antennas to cover the gallery and the ground floor together
- Ráday House — A/V integration
- the venue's motorised LED wall — content management and operation included — is also Pantheon Sound's responsibility, with sound and visuals in one A/V frame
- Kálvin Square street music — PA

- Kálvin Square street music — FOH
- Allen & Heath CQ18-T
- Jazz courtyard — PA

Highlighted venue — outdoor jazz courtyard near Kálvin Square
The festival's smallest and most intimate venue is an outdoor jazz courtyard near Kálvin Square in central Budapest. The genre demands here are entirely different from those at the church or the galleried ceremonial hall: the detail-rich dynamics of jazz and the courtyard's enclosed-yet-outdoor acoustic are the starting point.
The setup is deliberately minimal — two tops, two subs, a compact FOH position. The aim is not to maximise coverage but to preserve the genre's intimacy: keep the sound near the audience, don't overpower the space.
