FireFinder XLSV
Audio Level Conversion Card
Model ALCC
Product Overview
The Audio Level Conversion Card (Model ALCC) converts
speaker-level audio at 70VRMS from the MXLV - Model
ZAC-30 amplifier or the FireFinder XLSV - Model ZAC-40
amplifier to line-level audio. Audio can be provided
between the MXLV and FireFinder XLSV systems by
installing Model ALCC in a remote FireFinder XLSV system
.
The line-level audio output of Model ALCC can then be
inputted into the Audio Input Card (Model AIC) of the
remote FireFinder XLSV system.
Specifications
Model ALCC provides the capability of conducting a
global-emergency page across multiple, remote FireFinder
XLSV nodes with each audio riser holding a maximum of
63 nodes. The emergency page originates at a FireFinder
XLSV or MXLV global-paging station, where it is broadcast
at 70VRMS over an audio riser by a Model ZAC-40
(FireFinder XLSV) or Model ZAC-30 (MXLV) amplifier. A
single, remote FireFinder XLS node contains one (1)
Model ALCC, which steps the incoming speaker-level
audio down to line-level audio that is compatible with the
AIC audio input (0.775VRMS, independently adjustable to
±6dBu).
Model AIC digitizes the audio, which is subsequently
transmitted by a Model DAC-NET to local amplifier(s) for
broadcast over the local speaker zones.
Model ALCC is capable of supporting two (2) global-paging
stations, since Model ALCC incorporates (2) two,
independent audio channels. In cases where simultaneous
paging should occur, Model ALCC automatically prioritizes
the signal on the primary channel over the secondary
channel. On-board, audio-detection circuitry monitors the
audio risers for incoming audio, while supervision circuitry
reports any issues with the audio path, via front-accessible
LEDs. If necessary, supervision circuitry disconnects its
output from the Model AIC input, causing a trouble
command to be reported to the system.
Model ALCC relies on the originating amplifier for
supervision of the audio risers and on Model AIC for
supervision of the connection to Model ALCC. Since Model
AIC monitors the presence of signal on its audio input,
Model AIC is responsible for reporting audio path faults to
the FireFinder XLSV system.
Model ALCC plugs into one (1) slot in the CC-2 or CC-5 card
cage, and can occupy any slot within the card cage.
