Playing sound through the projector

Playing sound through the projector

You can make use of the projector (mixed mono) speaker in your presentations, and also connect separate amplified speakers to the AUDIO OUT socket of the projector.

If you have a separate sound system, you will most likely want to connect the audio output of your Video source device to that sound system, instead of to the mono audio projector.

You can also use a microphone to output the sound through the projector speaker.

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 61 for details.

The table below describes the connection methods for different devices, and where the sound is from.

AUDIO OUT

The selected input signal determines which sound will be played by the projector speaker, and which sound will be output from the projector when AUDIO OUT is connected. If you select a PC signal, the projector can play the sound received from AUDIO IN 1/MIC.

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.

There are two ways to adjust microphone volumes.

Directly set microphone volume levels in the SYSTEM SETUP: Advanced > Audio Settings > Microphone Volume menu or press MIC/VOL keys (+/-) on the remote control.

Set projector volume levels in the SYSTEM SETUP: Advanced > Audio Settings > Volume menu, or press VOLUME+/VOLUME- 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 SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.

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