transistor stages, particularly in the case of elevated temperature.
Transformer overheating will result in a temporary shutdown of the
affected channel; when it has cooled to a safe temperature, the
transformer will automatically reset itself. Controlled slew-rate
voltage amplifiers prevent RF burnouts. And input overload
protection is provided by current-limiting resistance at the input.
Turn On: Four-second delay with no dangerous transients. Delay
time can be changed (contact Crown’s Technical Support Group).
Accessories: Crown PIP and PIP2 modules including IQ-PIP
modules.
Construction
Steel chassis with durable black finish, aluminum front panel with
Lexan overlay, and specially designed flow-through ventilation from
front to side panels.
