About the microphone input

•If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the projector.

•You can use a wireless microphone as long as a wireless module is attached to the projector's microphone input jack and it works well with the associated devices.

•To ensure a quality use of the wireless microphone, it is recommended that your microphone conforms to the specifications listed in the table below.


Signal	Parameter	Min	Type	Max
Microphone	Transducer Principle				Dynamic
Microphone	Impedance	300		1K	ohm
	Frequency response	600		16K	Hz

•There are two ways to adjust microphone volumes.

•Directly set microphone volume levels in the Video/Audio > Audio Setting > Microphone Volume menu.

•Set projector volume levels in the Video/Audio > Audio Setting > Volume menu, or press Volume keys (+, -) on the remote control. (The projector volume setting will affect the microphone volume.)

•To make the microphone input available when the projector is in standby mode, turn on the Video/Audio > Audio Setting > Active Audio Out menu.

•If the microphone is not working, check the volume setting and cable connection.

•You might get feedback noise from the microphone when you are too close to the speaker of the projector. Move the microphone away from the speaker of the projector. The greater volume you require, the greater distance you need to be away from the Speaker to prevent the noise.

PJD6345, PJD6544W specifications

The ViewSonic PJD6544W and PJD6345 are two prominent models in the realm of portable projectors, designed to deliver exceptional performance for both educational settings and business environments. Known for their advanced features and reliable technology, these projectors cater to users seeking high-quality visuals and user-friendly operation.

One of the key highlights of both projectors is their high brightness levels. The PJD6544W boasts an impressive brightness of 3,200 lumens, while the PJD6345 offers a slightly lower brightness of 3,000 lumens. This makes both models suitable for use in well-lit rooms, ensuring that presentations and videos maintain visibility without compromising clarity.

The resolution of the PJD6544W is another noteworthy aspect; it features a native WXGA resolution of 1280 x 800 pixels, providing a wider aspect ratio ideal for high-definition content. The PJD6345, on the other hand, offers a native SVGA resolution of 800 x 600 pixels, which is still effective for standard presentations. These resolutions allow for sharp images and vibrant colors, enhancing the viewing experience.

In terms of technology, both projectors utilize DLP (Digital Light Processing) technology, which contributes to improved color accuracy and overall image quality. DLP projectors are known for their longevity and low maintenance, as they do not rely on filters that require regular replacements. This makes both the PJD6544W and PJD6345 reliable choices for users who value performance and durability.

Moreover, the integration of BrilliantColor technology in these models enhances the color range significantly, allowing for brighter yellows and richer hues. This feature is vital in educational and professional contexts where visual engagement is key to effective communication.

Portability is another strong suit of these projectors. Weighing just around five pounds and featuring compact designs, both the PJD6544W and PJD6345 are easy to transport between different locations, making them ideal for users who regularly deliver presentations outside their usual environment.

For connectivity, the PJD6544W and PJD6345 come equipped with a variety of options, including HDMI, VGA, and USB ports, ensuring compatibility with a range of devices, from laptops to media players. These versatile connectivity options simplify the setup process and enhance user convenience.

In conclusion, the ViewSonic PJD6544W and PJD6345 projectors stand out in the market due to their powerful brightness, high-resolution imaging, DLP technology, and user-friendly features. Whether for classroom instruction or corporate presentations, these projectors provide consistent performance that meets the needs of modern users while maintaining portability and efficiency.
