Crane Song Avocet 2A Box
The Crane Song Avocet Box is the 2 RU 2-channel "mainframe" of the Avocet II system and is what is added to an existing Avocet II system to add additional channels for surround monitoring.
For absolutely critical Avocet II installations, a Crane Song Avocet Box is a fine unit to keep in reserve as your own zero-downtime insurance. The need is unlikely, but some folks sleep better at night knowing they're covered no matter what.
This is NOT a fully functional Crane Song Avocet. It requires the Remote II which is only available as part of the whole Crane Song Avocet II Monitor Controller system.
