iPhone
Every feature free. No ads or subscriptions. One-tap scenes for Denon & Marantz. 36 receiver profiles built from owner diagnostics. Tips are optional.
Control your Denon® or Marantz® AV receiver from your iPhone. Sotto is calm and instant: every tap responds the moment you touch it, and the app is built around scenes instead of receiver menus.
WORKS WITH
Network Denon and Marantz receivers that accept the manufacturers' IP control protocol, roughly 2013 and newer: Denon AVR-X, AVR-S, AVC and DRA models; Marantz SR, NR, CINEMA and AV models. 36 models are Verified from a snapshot of that exact receiver, so zones, volume ceiling and room correction come from the hardware rather than a generic default: Denon AVR-E400, AVR-A1H, AVR-X6800H, AVR-X6500H, AVR-X4800H, AVR-X4400H, AVR-X3800H, AVC-X3700H, AVR-X3600H, AVR-X2800H, AVR-X1800H, AVR-X1600H, AVR-X1000, AVR-S760H, AVR-S750H, AVR-S650H, AVC-S660H, AVR-S700W, AVR-2113, AVR-1613, AVR-2313, AVC-A110, DRA-800H; Marantz CINEMA 30, CINEMA 50, CINEMA 70s, AV8805A, SR8015, SR7015, SR6011, SR6010, SR5015, SR5013, SR5009, NR1711, NR1504 (AVR and AVC versions share a profile). Other network models run in experimental mode; available controls depend on the receiver. CEOL and M-CR network CD receivers remain experimental, with model-dependent power, source control and volume ranges; the dB display is AV-specific. Not sure? Try the built-in demo receiver first; no hardware needed.

• Inputs, shown with the names you set on the receiver itself

SETUP
Same Wi-Fi as the receiver, Network Control on. Sotto finds receivers on your network, or takes an IP address by hand, and tests the connection before you finish. If discovery fails, allow Local Network access for Sotto in iOS Settings.
FREE, ALL OF IT
Every feature, every receiver. No subscription, no ads, no account, no tracking. Your settings stay on your device, and Sotto controls the receiver over your local network only. The one thing that can leave it is album art, which HEOS serves from the streaming service when that is what is playing. If Sotto makes your evenings calmer, there is an optional tip jar in Settings. That is the whole business model.
Sotto controls the receiver. It does not set up HEOS speakers or browse HEOS music sources; keep the HEOS app for those.
This app is not affiliated with, endorsed by, or sponsored by Denon, Marantz, or Sound United. "Denon" and "Marantz" are trademarks of their respective owners and are used here only to describe compatibility.
Inputs hidden in your receiver’s setup now stay out of Sotto’s input choices when the receiver supplies its visibility settings.
HEOS receiver discovery and group diagnostics now handle more response formats reliably. The Marantz CINEMA 70s profile also recognises HEOS support confirmed by owner diagnostics.
Thank you to everyone who shared a diagnostic report and helped us improve compatibility.
