  • TypeAmplifiers & Receivers
  • ColorBlack
  • Weight36.00
  • FeaturesHigh-efficiency Class-D amplification
  • High-efficiency Class-D amplification reduces heat and power draw
  • Six stereo inputs (four RCA, one 3.5 mm, one selectable 3.5 mm/Toslink) connect multiple sources
  • 8×6 matrix routes any input to any of eight zones independently
  • Bridgeable channels deliver 100 W into 8 Ω for demanding speakers
  • PA trigger on Source 1 overrides all zones for priority announcements

8-Zone Audio Distribution System

The Monoprice 144518 distributes audio from six stereo sources to eight independent zones. Installers configure routing per room using the supplied remote or in-wall keypads. It suits whole-home background music or commercial paging installations. Class-D amplification keeps the chassis cool during continuous operation.

Sustained Output and Thermal Behaviour

Each channel delivers 50 watts into a 4-ohm load or 25 watts into an 8-ohm load continuously. Bridged pairs provide 100 watts into 8 ohms for larger spaces. The high-efficiency Class-D design maintains stable output without thermal throttling during extended playback sessions. Euroblock connectors simplify long cable runs.

Upgrade Path and Fitment

The unit replaces a basic stereo receiver plus external speaker selectors when more than two zones are required. It adds matrix switching, IR distribution, and a dedicated mute trigger for safety announcements. The jump is justified when independent source selection per room is essential. Buyers needing network streaming or app control should look elsewhere.

Questions about this item

How much heat or power draw should I expect from the Class-D amplifier when it runs all day across eight zones?

Class-D amplification is high-efficiency, so the unit stays cooler and draws less power than traditional designs even during continuous multi-zone operation.

Which source devices and speakers must I already own to use the six stereo inputs and eight amplified outputs?

You need up to six source components with RCA, 3.5 mm or Toslink outputs plus speakers rated for 4-ohm or 8-ohm loads to connect to the Euroblock speaker terminals.

Can I bridge channels to drive older 8-ohm speakers that need more power than 25 watts per channel?

Yes, bridging two channels delivers 100 watts into an 8-ohm load, giving extra headroom for legacy speakers that require higher output.
