f. When do I need to use this module?
o
D-001T:
When connecting 1 or 2 balanced mic or line input sources.
o
D-001R:
When connecting 1 or 2 unbalanced line sources. Channel 1 or Channel
2 – 2 x RCA connectors provide stereo signal summing. Or use one RCA
connector from Channel 1 and one RCA connector from Channel 2 for Stereo Input.
o
AN-001T:
When using 1 or 2 AN-9001 sensing mics for Ambient Noise Control
o
ZP-001T:
When interfacing with a telephone analog extension port (FXS) (Ring
Signal Mode), to allow using a phone extension as a paging source or to a
standard line level audio output of the telephone system which passes DTMF
signals with a contact closure output (Paging Port Mode).
–NOTE: If there is a standard line level audio output from telephone system which
does not pass DTMF, or does not have the contact closure output, we would
instead recommend using a D-001T module with the input set to VOX
.
o
T-001T:
When connecting to 3 or more external amplifiers (the base 9000 unit has
at least 2 outputs, either 2- line outs, 2- powered outputs or one of each).
o
C-001T:
When connecting to 5 or more contact-closure ins or outs (the base 9000
Series unit has a compliment of 4 contact closure ins & outs).
o
900 Series:
When a special function (i.e.-message repeater, tone generator) or
only simple operation is required (input w/volume control). These also work in a
pinch when a 9000 Series module is not available.
g. What if I Need More Inputs/Outputs?
•
The input/output configuration on the 9000 Series may be expanded to a full
compliment of 8 Inputs (4 modules) x 8 Outputs (3 modules, plus built-in 1&2). If
the application requires more than this, you have a few options:
a. Although 9000 units cannot be truly “cascaded”, the outputs of one may be
“subbed” into the inputs of another unit. It’s also possible to set
programming via contact in/out so that memory change and other functions
may operate in sync.
b. Depending on the application, the inputs or outputs of multiple 9000s may
be able to operate independently (negating the need for running in tandem).
For example: when running independent paging or BGM sources to isolated
zones. Beyond this, there may simply be a need for a larger mixer (check
out the TOA D-901).
h. What are the PRE OUT & AMP in connections used for?
These are used as a “loop” in/out and allow connection of external
processing equipment (such as an equalizer, compressor or feedback
suppressor). Of course, the good news is the 9000 Series is equipped with an
ample amount of on-board processing. However, in the event you require some
piece of outboard gear to patch in between the preamp and power amp sections,
these loops (also referred to as “inserts”) are provided on the powered models.
There are 2 channels of in/out loops on the dual powered versions-A-9060DH,
A-9120DH & A-9120DL, and a single loop in/out on the A-9060S, A-9120S & A-
9240SH.
