Analog audio input connector — Connect a balanced or unbalanced audio source to
L
this 5-pole captive screw Audio In connector to embed analog audio in the HDMI output
signal. Input gain range is -18 dB to +24 dB. The default is 0 dB (see
Connections on page 17).
ATTENTION:
• The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inch (5 mm). If the exposed portion is longer, the wires may
touch, causing a short circuit between them. If the exposed wires are shorter,
they can be easily pulled out, even if tightly fastened by the captive screws.
•
La longueur des câbles exposés est primordiale lorsque l'on entreprend de
les dénuder. La longueur idéale est de 5 mm (3/16 inches). S'ils sont un peu
plus longs, les câbles exposés pourraient se toucher et provoquer un court
circuit. S'ils sont un peu plus courts, ils pourraient sortir, même s'ils sont
attachés par les vis captives.
•
Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.
• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés
dans les terminaisons des <connecteurs> à vis captives et pourraient sortir.
• For unbalanced audio, connect the sleeves to the ground contact. Do not
connect them to negative (–) contacts (see the Extron Audio Wiring Card).
•
Pour l'audio asymétrique, connectez les manchons au contact au sol. Ne
PAS connecter les manchons aux contacts négatifs (–) (voir le Audio Wiring
Card d'Extron).
+V connector — The +V pin constantly outputs +5 VDC power with 200 mA total

(shared between pins). Use this pin when power is needed for external Tally LEDs, such
as those on the Extron CCB 30 contact closure remote.
