70V 2-Zone Speaker Selector 100W

The Monoprice 138165 is a 70V speaker selector designed for commercial audio installations. It provides two independent mono zones each rated for 100 watts, allowing separate volume control and on/off switching per zone. A single 2-conductor input feeds both zones while a pass-through output enables daisy-chaining additional selectors. The unit weighs 2.60 units and suits distributed background music or paging systems.

Installers needing two separately managed 70V zones

This selector suits installers who need independent level adjustment for a pair of 70V speaker runs from one amplifier feed. It is not for buyers who require more than two zones or who need stereo zone control. It also does not suit low-impedance 8-ohm speaker lines or installations demanding per-zone impedance matching beyond the 80-watt 70V speaker limit per zone.

Check amplifier output and wiring before ordering

Verify that your amplifier delivers a 70V line output compatible with the selector’s single 2-conductor input. Confirm the total 70V speaker load on each zone stays within the 80-watt support rating. Ensure you have 2-conductor cable for the input, zone outputs, and any daisy-chain pass-through connections required by your layout.

Questions about this item

What amplifier output is required to drive the 70V 100-watt zones?

Connect a 70V amplifier output to the single 2-conductor input; the selector then distributes up to 100 watts per zone to your 70V speakers.

Can I keep my existing 70V speakers rated below 80 watts per zone?

Yes, each zone supports up to 80 watts of connected 70V speakers, so lower-wattage models work within that limit.

How do I confirm both zones are active after wiring?

Turn each zone's on/off switch on, adjust its volume knob, and verify sound from the speakers attached to that zone.
