NEC R 37 Xtra External Speaker Connections

External Speaker Connections

External speakers may be connected to the monitor to reproduce sound from VIDEO 1, VIDEO 2, RGB 1 or RGB 2 signal sources.

External speakers may be connected directly to the EXTERNAL SPEAKERS terminals or indirectly by connecting a stereo system amplifier to the audio outputs.

WARNING: Speakers that are installed next to the monitor must be shielded against electromagnetic radiation which can cause color distortion in the CRT and is not covered under the warranty.

If non-shielded speakers are used, they must be located a minimum of 4 feet away from the monitor.
