Patent-pending protection
Big voices. Safer speakers.
Live vocals have sharp peaks that home audio gear was never designed to handle. Intelligent compression and limiting control those peaks before they reach your speakers.
Unprocessed input
Peaks + dropouts

Limit harsh surprises
Enthusiastic high notes and sudden feedback are managed before they become dangerous spikes.
Keep the energy
Protect without flattening
The room still feels live, while vocals stay clear and the music remains balanced.
Two independent inputs
Two mics. One great duet.
Balance a quiet singer and a big voice independently. Both inputs accept standard dynamic microphones through XLR or quarter-inch connections.
One living room, one night
The room becomes the stage.
A TV, two microphones, and one box between them. Everything below is the same evening, from the first song to the last.
One box, in the middle of it.
It sits by the TV, takes both microphones, and stays out of the way for the rest of the night. Nobody in these photos had to think about it once the first song started.

The practical questions
Before you bring it home.
How hard is setup?
Connect your source, connect Seratone to your TV or sound system, plug in your microphones, and sing. Most permanent setups only need to be wired once.
What happens when Seratone is off?
HDMI OUT becomes a clean passthrough, so your TV setup keeps working. RCA and optical outputs are active when Seratone is on in karaoke mode.
Can I use the music apps built into my TV?
Yes — Seratone supports HDMI ARC. Connect HDMI OUT to your TV's HDMI ARC or eARC port and hold the power button to switch into ARC mode. Your TV's own apps, or anything you cast to it, become the music source, with your microphones mixed in over that one cable.
Do I need special songs or another subscription?
No. Use Apple Music Sing, Spotify Sing Mode, YouTube, Karafun, Smule, or the karaoke app you already prefer.
Will it work with my speakers?
Seratone supports HDMI, stereo RCA, and optical output. That covers TVs, soundbars, home-theatre receivers, powered speakers, and studio monitors.
Can I use my own microphones?
Yes. The two combo inputs accept dynamic microphones over XLR or quarter-inch TRS. Microphones requiring 48V phantom power are not supported.
