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 Guide.
NOTE:
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 audio level of the selected input has
been adjusted to the –10 dBV internal reference level. (In Audio Setup mode, the
audio of the selected input is automatically tied to output 1.) See
Audio Gain and
page 31.
Input and Output Selection Controls and Indicators
NOTE:
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
beginning on page 20.
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
Presets", beginning on page 20.
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
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
Keep the switcher out of bright light to prevent interference with the IR
signals from the IR 501 remote control.

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