Extron electronic MVX 84, MVX 88 Power/audio/data LED and infrared sensor, Power/data/audio LED

Power/audio/data LED and infrared sensor

1Infrared remote sensor — This sensor receives infrared (IR) signals from the optional IR 501 small matrix universal remote control. The IR remote control must be pointed within 30 degrees of this sensor for best results.

Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR Remote Control User’s Guide.

Keep the switcher out of bright light to prevent interference with the IR signals from the IR 501 remote control.

2Power/data/audio LED —

•When lit, the Power LED indicates that power is applied to the matrix switcher.

•When blinking off and on, the Power LED indicates that an IR signal has been received.

•In Audio Setup mode, the Power LED also serves as an audio meter that is tied to output 1. The LED blinks frequently when the selected input’s audio level has been adjusted to the –10 dBV internal reference level.

(In Audio Setup mode, the selected input’s audio is automatically tied to output 1.) See Adjusting input audio gain and attenuation on page 3-18 and Optimizing the Audio on page 3-26.

Input and output selection controls and indicators

If the switcher has fewer than eight inputs or outputs, it has fewer input or output buttons and LEDs.

3Input buttons and LEDs — The input buttons and LEDs select and identify inputs.

Alternate preset selection function — The input buttons and LEDs also serve as preset selection buttons and indicators, allowing you to select presets to either save or recall. A more detailed explanation of the presets functions is included in Using presets, beginning on page 3-16.

4Output buttons and LEDs — The output buttons and LEDs select and identify outputs.

Alternate preset selection function — The output buttons and LEDs also serve as preset selection buttons and indicators, allowing you to select presets to either save or recall. A more detailed explanation of the presets functions is included in Using presets, beginning on page 3-16.

Alternate audio indication function — The Output 1 through Output 3 LEDs also serve as the input audio level indicators, each indicating a range of 6 dB when lit:

•Output 1 LED off = 0 dB to 5 dB

•Output 1 LED lit = 6 dB to 11 dB

•Output 1 and 2 LED lit = 12 dB to 17 dB

•Output 1 through Output 3 LEDs lit = 18 dB

See Adjusting input audio gain and attenuation on page 3-18.

Alternate audio adjustment function — On 8-output switchers, the Output 7 and Output 8 buttons and LEDs also serve as the Down () and Up () controls and indicators. See 10 and 11 .
