LIVEMIX AD-24 4
5. INPUT LIGHTS: These lights give you a visual indication of the incoming audio signal level. Use
the signal level lights as a guide, when adjusting the output volume of the signal sources that are
feeding the inputs of the AD-24.
The input lights can be one of three colors based on signal strength:
-20dB (Green): A green light indicates a healthy signal level, and is where you want to see your
signal strength most of the time.
-6dB (Yellow): The yellow color indicates that the signal is
almost too loud, and should only occur when a signal is at
an occasionally loud moment.
0dB (Red): The red color indicates that the signal is
“overloading” the input, and needs to be turned down at
the source. If you see red lights, the source signal needs to
be turned down in volume, or the signal will be distorted as
it is sent to the other parts of the Livemix system.
6. +4DBU/-10DBV SWITCHES: These buttons allow you to configure each pair of inputs for
different types of incoming signals.
If using unbalanced -10dBV signals, set the button to the
OUT position. This setting will optimize the connectors for
the lower-level signals common in consumer equipment
such as a portable digital audio player, a consumer CD
player, etc.
If using balanced, +4dBu signals, set the button to the IN
position. This setting will configure the connectors for the
higher-level signals you would find in the direct outputs of a
professional audio mixer or rack of standalone microphone
preamplifiers.
7. LIVEMIX DATA OUT: This connector is the output of the
AD-24. It sends a digitized audio signal containing all 24
input channels to a MIX-16/32 over a single shielded CAT5 or CAT6 cable.
8. LIVEMIX DATA LIGHT: This light will illuminate green when the AD-24 has a valid connection
and is sending data to a MIX-16/32. If this light is red, it is an indication that the connection to
the MIX-16/32 is not functioning properly. A shielded CAT5 or CAT6 cable is required for proper
sync.
NOTE:
The AD-24 allows you to
select between these two
operating levels, by channel
pairs. This means that you
may mix and match different
incoming signal sources, and
do not have to choose an
overall input level for all 24
channels.
NOTE:
If you see a red light, it may
also be an indication that you
have the +4/-10 switches in
the wrong position.
