Benefits & Features

• Input (A/D) expander.
• Used with SymNet 8x8 DSP and CobraLink.
• Twelve (12) mic/line inputs with phantom power.
• 64 channels of SymLink busing.
• One (1) RS-232 port. Transmit and Receive SymLink ports.

Product Details

The BreakIn12 has no onboard DSP, and cannot function in a stand-alone mode. The BreakIn12 purpose is to increase system analog input channel count while reducing system cost-per-channel.

Each analog input is mic/line-selectable with five gain levels and available 48V phantom power per channel. Onboard SymLink Bus connectors support the interfacing of BreakIn12 units within a SymLink Ring. Bus assignments and performance characteristics are configured within SymNet Designer software. While DSP requirements vary among system designs, two BreakIn12 units can generally be supported by one 8x8 DSP. All I/O parameters are accessible via outboard control from third-party control systems, ARC Wall Panels, or other control devices connected to a SymLink Ring.

Mechanical Data

SPACE REQUIRED
1U (WDH: 48.3 cm x 26.7 cm x 4.37 cm / 19 in x 10.5 in x 1.72 in). Depth does not include connector allowance. Allow at least 1 inch additional clearance for rear panel connections. Additional depth may be required depending upon your specific wiring and connections.

ELECTRICAL
100 to 240 VAC, 50-60 Hz, 75 watts maximum. No line voltage switching required.

VENTILATION
Maximum recommended ambient operating temperature is 30 C / 86 F. Fan on equipment right pulls hot air out of unit. Air intake at equipment left. Ensure that the left and right equipment sides are unobstructed (5.08 cm, 2 in minimum clearance). The ventilation should not be impeded by covering the ventilation openings with items such as newspapers, tablecloths, curtains, etc.

WEIGHT
3.0 kg (6.6 lbs.)
