Using external speakers

Up to two speakers with built-in amplifiers can be connected to the product as external speakers. When using the

product in a layout or a multi-participant conference that cannot be covered by only the built-in speaker, use external

speakers to extend the area where playback sounds can be heard.

Note

Use external speakers with a low latency and distortion.

If you use external speakers with a high latency or distortion, it may cause an echo phenomenon on the other side.

■

Preparation

Prepare audio cables (RCA pin plug) to suit the number of external speakers to be connected.

• Speakers with a built-in amplifier may have a different shape of the audio input terminal depending on the model. Use an

audio cable with the plug shape that matches the shape of the audio input terminal for each of your speakers. The product

must be connected to an RCA pin plug regardless of the type of the plug to be connected to each speaker.

• Monaural signal is output as an audio signal from both external speaker terminals.

■

Installation

Place all external speakers 1 m to 20 m (3.3 ft to 66 ft) away from all microphones.
