Question: In your product literature the WP-2 is described as a 2 channel switchable PL wall plate with a 3-pin XLR jack. Can it be used for just a single PL channel?
Answer: Yes, the WP-2 wall plate can support a single PL channel, simply bypass the channel A/B switch to accomplish this. To avoid confusion the toggle switch can be removed. The WP-2 can support up to (2) channels of PL wired intercom by switching the intercom from channel A to B by use of the toggle switch on pin 3 of the XLR jack.
