C.
SYNC Port (RJ-45):
SYNC allows the BaseStation to receive and use a sync source from
another CB2 BaseStation or from a separate CrewCom system. See
for more information. Each Sync port's status LEDs indicate the
status of the sync link. (See
.)
Important
: You can sync two CB2 BaseStations together with or without audio
connected between the devices. You can sync one CB2 BaseStation to a CrewCom
system for RF compatibility only; no audio connection will be made via the sync
connector in this application.
D.
2-WIRE Intercom Port (x 2):
The Intercom Channel ports (A and B) allow the user to connect
the BaseStation to 2-Wire external intercom systems. The XLR-3M/F 2-Wire intercom ports
interface with Clear-Com, RTS, AudioCom (Balanced), and other compatible intercom systems.
The pairs of XLR-3M and XLR-3F are electrically identical—including the grounds—but the
grounds of the two channels are electrically isolated from each other. Each connector pair is
transformer isolated. The 2-Wire Intercom settings can be adjusted under the
Wired Settings
menu. You must have external 2-Wire power for the 2-Wire port to work. (See
.)
E.
4-WIRE Intercom Port (x 2):
The RJ-45 4-Wire Intercom ports (A and B) interface with 4-Wire
intercom systems and devices. This is an audio-only port and does not support data transfer. The
connector is balanced and transformer isolated. These connections do not use standard CAT-5e
cables. The cables used must be wired per the CrewCom pin connections and per the device to
which you are connecting. (See
"More About the CB2 BaseStation 4-Wire / RJ-45 Connection" on
.) Nominal line level is +5 dBu. The 4-Wire Intercom settings can be adjusted under the
Wired Settings menu. (See
"4-Wire Intercom Connectivity" on page 60
.)
F.
RELAY Connection:
The CB2 BaseStation includes a single Phoenix connector with 2 contact
closures for interfacing with the Stage Announce (SA) Relay. The user has access to both the
normally open and the normally closed contacts for each relay. Rated load for the contacts is: 0.3
Amp at 125VAC, 1 Amp at 30VDC. (See
"Stage Announce Relay" on page 66
.)
G.
STAGE ANNOUNCE (SA):
Stage Announce (SA) is used to output system audio to a dedicated
audio output. SA uses an XLR-3M connector. The connector is balanced and transformer
isolated. Nominal line level is +5 dBu. The SA output level can be adjusted under the
Wired
Settings
menu. (See
"Wired Settings Menu" on page 52
.)
