Physical Characteristics |
Chassis |
Black powder-coat chassis with all aluminum construction; designed for stand-alone or rack-mounted operation. The amplifier occupies five EIA 19-inch-wide rack units |
Weight |
110 lbs. (50 kg) |
AC Power |
Three-phase, 208 VAC ±10%, 47-60 Hz, 20A AC service (400 VAC ±10%, 15A version available). A toggle switch circuit breaker opens all legs of the AC mains on excess current demand. |

Humidity |
70% or less, non-condensing |
Cooling |
Forced air-cooling from front to back through removable filters via four 100 ft3/min. fans. No space is required between rack-mounted amplifiers. Air filters are removable from the rear via one fastener per side and may be eliminated if cabinet filtration is provided. |
Dimensions |
