Ray260 with active and passive speakers

[Hippokampos]

It is my intent to install a handset below as well, sorry I neglected to mention that. I would like to be able to listen and speak from below during radio nets and other non-moving communications, and be able to basically turn it off below and only use the radio from the cockpit while on long passages.

My current Icom with RAM in the cockpit requires the vhf to be turned to full volume at the chart table to be able to hear the vhf on the remote mike in the cockpit, and that it proving to be very disruptive to the of the off-watch crew.

I'm guessing the two handsets would essentially work independently, regardless of whether they have an active or passive speaker attached, but an active speaker can be turned up louder. Is this correct, or is one of the handsets a "master" that must be turned on first or at all times?

Thanks!
