8-Zone Speaker Hub

The Monoprice 138161 distributes a single amplifier signal to up to eight pairs of speakers for whole-home audio. Removable terminal blocks simplify wiring for each zone. It is built for installers or owners expanding a stereo system across multiple rooms.

Amplifier and Impedance Check

Verify your amplifier can handle the combined load of all connected speakers without impedance matching circuitry inside this hub. The manufacturer strongly recommends adding external impedance-matching volume controls to protect the amplifier from low-impedance damage. Ensure speaker wire gauges suit the terminal blocks before installation.

Passive Operation

The unit draws no power and adds no fan noise because it contains no active electronics. Heat generation is negligible during normal use. Its lightweight 0.49 kg chassis mounts easily in a rack or cabinet without ventilation concerns.

Highlights

  • Connect eight speaker pairs from one amplifier
  • Removable terminal blocks simplify speaker wire installation
  • No built-in impedance matching circuitry included
  • Impedance matching volume controls recommended for amplifier protection

Questions about this item

Does the Monoprice 138161 ship with speaker wire or terminal plugs, or must I supply them?

The hub uses removable terminal blocks that accept bare wire; speaker wire and any banana plugs or spade connectors are not included and must be purchased separately.

Should I choose an impedance-matching selector instead of this 138161 model for my eight-zone system?

This unit has no impedance-matching circuitry; if you plan to drive all eight pairs simultaneously, select a model with built-in matching or add impedance-matching volume controls to protect your amplifier.

What does the eight-pair rating mean when I connect the hub to my receiver?

It allows up to eight speaker pairs to share one amplifier output, but without impedance matching the combined load drops as zones are added, so the receiver must be stable at low impedance or you must use matching controls.
