- Mirror projection system enables wide 80-inch screen projection from a short distance of 0.6 m (1.97 ft).*1
- Equipped with a feedback camera for the interactive function, which enables text, graphics, or lines to be written onto projected images. Two interactive pens come supplied with each projector.
- Interactive functions feature auto calibration. Two users can work simultaneously with dual pens.
A faster frame rate and higher sensor resolution also provide smoother, more natural writing. - The HDMI input terminal supports 3D (frame packing, side-by-side, top-and-bottom, and frame sequential method).
Connect a 3D Blu-ray player to the projector to project Blu-ray 3D images.
- High brightness of 3,100 lm*2 and contrast ratio of 8,000:1*3 ensure bright and easy-to-view image projection in classrooms and meeting rooms.
- High-output 10 W speaker built-in.
- Abundant terminals including HDMI and two sets of RGB input terminals.
- Long lamp replacement cycle of up to 5,000 hours*4 for the PT-CW241R and 4,000 hours*4 for the PT-CW331R/CX301R.
- Audio can be output from the audio output terminal in Standby mode.*5
- Compatible with Crestron RoomView™.
- The lamp is easily replaced from the side even when the projector is installed on the ceiling.
- Wall color setting: white, light yellow, light blue, pink, and black board (dark green).*6
- Projector identification system for remote control allocation of up to six projectors.
- Security bar for protection against theft.
*1 For the PT-CW331R and PT-CW241R. 0.71 m (2.33 ft) for the PT-CX301R.
*2 PT-CW241R has brightness of 2,600 lm.
*3 During RGB signal input. LAMP POWER: NORMAL.
*4 This is the maximum value when the lamp power is set to Eco mode where the lamp is turned on for 2 hours and off for 0.25 hours.
If the lamp is turned on more times or kept on for a long time, the lamp replacement cycle will shorten.
In Normal mode, the lamp replacement cycle is 3,500 hours for the PT-CW241R and 3,000 hours for the PT-CW331R/CX301R.
The usage environment affects the duration of the lamp.
*5 Select the Menu for setting.
*6 The color of images projected onto a color board may vary from those of the original input signal.
