Station selection
Stations may be selected with continuous control voltages ("S&H" and
"advance" LED's off). With the "slot" LED lit, a tuner's slot# will be displayed
and selected with a sensitivity of .5 volts per slot, and the knob can be used to
alter the slot number. When "frequency" is displayed, the entire F.M. band is
spread over the 10 volt control voltage range, and the accompanying knob
may be used to alter the (frequency of slot 0 only).
With "S&H" illuminated, the control voltage will be sampled by an incoming
pulse, and with "advance" lit, an applied pulse will simply advance a tuner's
slot number.
Polyphony
The 272e incorporates a polyphonic resource, with the four tuners sequentially
providing "notes" with variable attack and decay times. The sustain switch
offers the possibility of sustaining the "notes" as long as the incoming pulse is
above the 5 volt threshold. Red LED's show the status of each tuner.
With the CV and pulse inputs in the Polyphonic section each tuner will overlap
with the others starting at Tuner A.
With the CV and pulse inputs in individual Tuner sections, the polyphonic
section will turn on
Settings of pots and switches, as well as station assignments, can be locally
stored and subsequently recalled by the model 225e or 206e preset manager.
To connect or disconnect this module from the central library function, push
the remote switch. A lighted red LED signifies a connection.
*Antenna setup
Install the panel and internal cable : A 272e I-O panel should be installed in
an available position on the back of your 200e boat . A 3-pin cable connects
the antenna to the back of the 272e module at 3-pin header “ANT1”
Plug in the antenna: Locate the two connectors on the I-O panel for the
272e. One connection is a standard Motorola antenna socket, the other a blue
banana jack with 12v power for the powered antenna. Connect the supplied
antenna to these. When the antenna is powered, a red LED will illuminate on
the antenna. Locate the antenna above the system and away from large
metal objects.
