Inputs
The ALM-12d console can accommodate up to twelve of the twenty two
available inputs in any combination (slots 1-12). Depending on the type of input
signal the slot will handle, it will be for mono microphone (-50dBu nominal),
stereo line analog (+4dBu balanced), or stereo line digital inputs.
The ALM-12d is designed to handle up to eight analog stereo line level
inputs. Two other stereo line inputs can be used for stereo signals or can be split
to provide four mono mic inputs (two each per stereo line input) instead.
The console can also handle up to eight digital stereo line level inputs, and
has two analog inputs dedicated to use as telephone caller inputs and an
additional analog mono Producer talkback input. Not all inputs are available at
the same time. An input must be selected by a FADER before it is available for
combination into a main output.
Analog Mono Mic Level Inputs
These inputs are used to connect to microphones, which typically put out
signals at relatively low signal strength, and therefore require more amplification
(increase in signal strength) to be properly audible in the output.
Analog Stereo Line Level Inputs
These outputs are typically used to connect to machines, such as tape decks,
cart machines, CD players, etc., that provide analog outputs.
Digital Stereo Line Level Inputs
These outputs are typically used to connect to machines, such as tape decks,
cart machines, CD players, etc., that provide digital outputs.
Producer Talkback Input
This input is provided to allow a line level signal from a remote location to
perform the talkback to Studio function. This input will only be heard in the
Studio output, and cannot be assigned to any fader or to any other monitor.
Sources (not exactly the same as inputs)
The word source is used to describe any audio signal that is used to drive a
particular section of the console. For the 12 FADERS, the source will be one of
the inputs to the console, but in the case of other sections of the console, such as
meters, monitors, and caller feeds, the source may be an input, or it may be one
of the console outputs, or buses.
For all 12 faders, the switched meters, and the Control Room and Studio
monitors, it is possible to have no source assigned by dialing up the selection
OFF. See the section on selecting sources for details.
Note: Mic level inputs c
be wired to the inputs of t
internal mic preamps. Y
must then wire the m
preamp outputs over to t
line level analog inputs y
want to use them with.
