Description of the DELTA System (cont.)
MT-3000 Multi-Tuner - 3 Broadcast Sources in One Chassis
MT-3000 Multi-Tuner • an ADA Bus™ Component • is used as up to three broadcast sources
in any configuration (FM/FM/AM, FM/TV/TV, etc.) The MT-3000 fully integrates
with MC-3000 Keypads on the ADA Bus™ to provide complete feedback in the form of
station frequencies with programmable preset labels. When selecting a tuner module,
the keypad will display the same information displayed on the MT-3000. While the MT-
3000 acts as three sources, it has only one AC power cord and will need to be turned on
when either sources 1, 2, or 3 are selected from a keypad. You can turn the MT-3000 on
using either an ACC-3000 or ACC-48. Also see FMA-1 and AMA-1 MT-3000 Tuner
Accessories below.

FMA-1 & AMA-1 • an MT-3000 Accessory • The FMA-1 is a remotely controlled FM Antenna
Preamplifier (not an FM antenna) and works in conjunction with the MT-3000 Multi-
Tuner's FM Tuner Modules. Typically, the FMA-1 is used when the FM antenna is
located away from the equipment mainframe. The FMA-1 should be located near the
antenna location and requires an RF Cable and 2 Conductor/18 Gauge w/Stranded
Shield control cable run from it to the MT-3000. Every time the user changes FM
stations, the FMA-1 is told which frequency the tuner is set for and thereby preamplifies
that particular frequency rather than the entire bandwidth. The end result is a more
finely tuned FM signal, preamplified prior to sending the signal through electronically
noisy environments. The AMA-1 AM Antenna and Antenna Preamplifier works
similar to FMA-1, except the AMA-1 is also an AM Antenna in addition to an antenna
preamplifier. This unit should also be located away from electronically noisy environ-
ments (typically an attic space). When using FMA-1s and/or AMA-1s, you will need
to run individual control cables and RF cables for each FM and/or AM Modules. In
typical Delta Systems, where the MT-3000 Tuner Module format is FM, AM, TV, you
will need one FMA-1 and one AMA-1, each with its own RF and Control Cable run to
the MT-3000. Please note, if you wish to use antenna preamplifiers, you will need one
FMA-1 or AMA-1 for every MT-3000 FM Module or AM Module. If your source format
is FM 1, FM 2, AM, you will require two FMA-1's and one AMA-1, each with its own RF
cable and control cable run to the MT-3000.
