OSD 70V 2-Zone Speaker Selector w/Volume Control, Direct Pass Through, Daisy Chain (200W)

This is for a 70V audio system usually used in retail, restaurant locations or for distributed audio (not stereo) in a larger home or building. Each unit provides 2 Zones of volume control and the number of zones can be expanded by "two zones" with each unit you purchase. For 4 zones purchase 2 units and connect the "thru" on the first unit to the "input" of the second unit. I just installed 2 units to provide 4 zones of control and they are working perfectly.

Su función es la que requería para controlar volúmenes ven 4 zonas

Using it to control 2 zone office speakers. Works just as expected. Good buy.

We bought this for our church basement sound system. Almost immediately the zone 1 button failed. I am getting a second unit and hope for better luck. It is a simple design and offers volume control on each zone. If this second one works as designed, it will give us the solution we need for our fellowship area.

Only for 1 pair of speakers not 2 pair

The 2-zone option is nice.

Worked perfectly as a little 2 zone volume control.

Ended up returning and buying another receiver. We wanted it for our outside speakers off our main receiver but it brought down the volume so low that we had to turn it up almost 50% to get regular sound. Then was afraid the kid were going to switch to the inside speaker and be so loud in the house. Did what it said but wasn't for us.

Unfortunately the product is broken.Very disappointed what is the policy for broken productThanks Greg
