PM14-3H   14-inch Broadcast Monochrome Monitor

 

Ikegami 3H-Series Monochrome Monitors The Ikegami Series -3H range of professional monochrome monitors provide the features and high performance necessary for sophisticated broadcast studio applications. 9-inch configurations are available as A) Bare chassis, B) Cabinet with handle and C) for 19-inch rack mounting in an 8-3/4-inch height for single, single with WFM space, single with Vectorscope space, and dual unit uses. 14-inch configurations are for cabinet use or for 19-inch rack mounting in a 10-1/2-inch height, slides are optional for the cabinet mount version.

  • Keyed back porch clamp, switchable to D.C. restorer Dual (A/B) inputs, front panel selectable Internal/ external sync, front panel selectable Notch filter on/off, front panel selectable on 14-inch Tally light Remote control (VIDEO SELECT, SYNC SELECT, TALLY ON/OFF)
  • An illuminant-D phosphor, as well as pre-set controls for brightness and contrast are also standard on the 14-inch unit. Pulse delay is optional on the 14-inch monitors; pulse delay and/or an illuminant-D phosphor are available on special order with the 9-inch monitors.
  • Series-3H monochrome monitors provide high resolution at high brightness, low geometric and differential gain distortion and excellent stability over a wide temperature, input voltage and APL range.
