Our Mid‑Level whole‑house audio systems have officially sold out, marking the end of a product line that has delivered exceptional performance and reliability to thousands of homes. If you recently purchased an MC-66 or MCA-66, rest assured your system remains fully supported.
If you're exploring options today, our Advanced Lync System remains available, offering premium features for those who want the very best. And coming soon, our next‑generation whole‑house audio platform arrives in April, with shipments beginning in May 2026. We can’t wait to share what’s on the way!
For current owners of an MC-66 or MCA-66 system, a handful of accessories are still available for purchase near the bottom of this page.
An HTD Mid-Level (MC or MCA) system can organize your home with up to six stereo audio zones (covering as many rooms as you’d like), each with independent source selection and volume control. Virtually any source that outputs audio, including music streamers, can be connected at a common, centralized location and made available to every room in the house.
Like all HTD products, HTD Mid-Level Systems are sold direct-to-consumer. Components are available separately and included in discounted sets near the bottom of this page.
For iOS and Android devices.
Why make MC or MCA the center of your whole-house audio system?
Use with existing wiring or run cables during new-home construction.
- From a central location, speaker cable should be run to each speaker.
- Optional: From the same central location, Cat 5 or higher cable should be run to every location where you want to install a wall-mounted control pad.
- Quick Start Video: MCA-66 (built-in 12-channel amplifier)
- Quick Start Video: MC-66 & Separate 12-Channel Amplifier
Professional-grade equipment with flexible configuration.
- Two central controller options: Model MCA-66 includes a built-in multi-channel amplifier. Model MC-66 offers greater flexibility because it requires a separate multi-channel amplifier. With one or more separate amplifiers, each zone can be configured with as much power, and as many speakers, as needed.
- Efficient Class D amplifiers produce a full, clean sound with dynamic headroom; a low-voltage trigger keeps them in an eco-friendly standby mode until power is needed.
- Proven designs include FCC and third-party ETL safety certifications. Museums, amusement parks, and even Topgolf have relied on HTD amplifiers to power speakers for many hours per day, all week long.
As source devices change, your system remains relevant.
- Connect older, newer, and future devices (music streamers, network media servers, CD players, cassette players, TVs, turntables, etc.) at the central location.
- Connect a music streamer to stream music using your phone or tablet. Within streaming apps such as Spotify and Tidal, look for symbols like these
to select the music streamer you want. One streamer is required for each unique stream, but that stream, as with any connected device, can be shared simultaneously and in sync with any number of zones. Only purchase the streamer(s) you need now and add-to or replace them years from now as streamers evolve. Read more.
Control with the HTD Home Audio app.
- From a single System Status page, select which source to hear and at what volume for all zones. Mute/un-mute all zones at once with a single button press.
- Drill into a zone to adjust treble and bass, or set all zones to the same source (party mode).
- Block specific zones and sources on a per user basis - great for kids and guests (or employees in a commercial application).
- When you connect a music streamer, you'll benefit from over 40 built-in shortcuts to popular streaming services like Spotify, Prime Music, Apple Music, and Tidal.
- Create groups for control of multiple zones at once.
- Create unlimited audio scenes called “presets” that set up as many zones as you'd like with a single button press.
Add wall-mounted control pads for convenience. (optional)
- Models KC6 and KC7 connect using Cat 5 (or higher) cable.
- Select a source and volume for one zone. Tap the power button to quickly mute and un-mute the zone.
- Long-press a source button to power on all zones to the same source (party mode).
- Long-press the power button to quickly turn off all zones in the home.
Automate with Alexa, Google Home, Home Assistant, and Siri.
- Requires our current gateway model, WGW-SLX.
- Use voice, schedules, and triggered events to control one or multiple zones. This includes launching app presets with a simple command.
- Combine audio commands with those of other smart devices for a truly immersive and hands-free home automation experience - e.g. "Wake up", "Entertain", "Leaving house", "Goodnight", etc.
