Extron electronic MVX 88 Series manual Infrared sensor and Power/audio/data LED, Preliminary

Infrared sensor and Power/audio/data LED

A	Infrared 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.

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

B Power/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

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

C	Input 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.
D	Output 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 J and K.
