Optimizing the Audio

PRELIMINARY

Operation, cont’d

Each individual input audio gain can be adjusted within a range of -18 dB to +10 dB to eliminate noticeable volume differences between sources and to achieve the best headroom and signal-to-noise ratio. Adjust the audio level as follows:

1.	Connect audio sources to all desired inputs and connect the audio outputs
	to output devices such as audio players. See “Video and audio input
	connections” and “Video and audio output connections”, in chapter 2,
	“Installation”. For best results, wire all of the inputs and the outputs balanced
	when possible.
2.	Power on the audio sources, the switcher, and the audio players.
3.	Apply audio signals to all inputs to be optimized.
4.	In Audio Setup mode (see “Adjusting input audio gain and attenuation”, on
	page 3-18) select among the inputs while observing the front panel Power
	LED. The LED blinks at a rate that corresponds to the highs and lows of the
	audio signal.
5.	As necessary, adjust the audio gain of each input so that the Power LED blinks

frequently for all selected inputs. If the LED is lit most of the time, the level is probably too high; if the LED rarely flashes, the level is too low.

As an alternative:

• If necessary, temporarily set the output 1 level to the consumer (-10 dBV) level (see the Audio output level SIS commands in chapter 4, “Remote Operation”).

• Measure the output 1 audio level (in Audio Setup mode, the selected input is tied to output 1) with test equipment, such as a VU meter, or listen to the output 1 audio with a critical ear.

Troubleshooting

This section gives recommendations on what to do if you have problems operating the MVX Series switcher.

1.	Ensure that all devices are plugged in and powered on. The switcher is
	receiving power if the power LED is lit.
2.	Ensure an active input is selected for output on the switcher.
3.	Ensure that the proper signal format is supplied.
4.	Check the cabling and make corrections as necessary.
5.	Call the Extron S3 Sales & Technical Support Hotline if necessary.
