Ingestion of dust into the projector leads to reduced brightness and a deterioration in picture quality.
The PLC-XC55/XC50 features a new dust-resistant design that limits the movement of air through the projector to the intake and exhaust vents. |
 |
| |
|
|
| |
A lens cover helps keep dust from finding its way into the projector around the lens, a longstanding problem with conventional designs.
A sliding cover plays the same role for the focus and zoom controls. |

Build-in airflow and air pressure sensors detect intake airflow during operation. When a clogged filter is detected due to airflow falling below a certain threshold, the filter is advanced automatically to replace the dirty surface with a clean one, eliminating the need to clean the filter. The filter cartridge replacement cycle is about one year*2.
The PLC-XC55/XC50's use of a large filter approximately three times as fine as previous models*3 keeps even microscopic dust from entering the projector.
*1 For projectors under 5 kg as of May 12, 2008.
*2 Guidelines based on 8 hours of use per day (actual filter operating time: approx. 3,000 hours). (Based on accelerated testing in the JIS D-0207 experimental environment.)
*3 Previous model: PLC-XU78/XU75 |

The PLC-XC55/XC50's security bar delivers enhanced security performance by accommodating commercially available wire cables up to 11 mm in diameter. These strong cables are an effective way to prevent equipment theft. |

Along with its mobility, the PLC-XC55/XC50 features high-output
7 W speaker that deliver sufficient audio authority for the projector to be used in conference rooms, classrooms, and other spaces with only the built-in speaker. |

An auto setup function searches for an input signal and performs keystone correction once the projector is put in place and turned on, simplifying setup. |
|
| |
|
|
 |
 |
| |
Automatic digital correction of keystone distortion caused by the relative position of the projector and the screen makes it easy to set up the projector (correction angle: up to ± 20° vertically). |

The PLC-XC55/XC50 provides industry-standard digital interface support with a DVI-I input jack and D-Sub 15-pin input and output jacks. |

This mode lets you use a blackboard as a projection screen*3.
It adjusts the colors to make images look similar to those projection to an ordinary white screen.
*3 The colors of images projected onto a blackboard or color board may vary from those of the original input signal. |

A 1/2x to 16x digital zoom function complements 1.2x optical zoom,increasing the flexibility with which the PLC-XC55/XC50 can be positioned for use. |
|
 |
| |
An easy-off function enables the projector to be unplugged immediately without waiting for the lamp to cool down. |
