F1222 Manual (3.0E) Safety instructions
Safety precautions
Before you use our products, read the manual
carefully and observe all the safety precautions.
They will protect you and help to avoid equipment
failures.
Keep this manual in a safe place so that it is
available for future reference.
If you supply d&b products, please draw the
attention of your customers to these safety
guidelines. Enclose the relevant manuals with the
systems. If you require additional manuals for this
purpose, you can order them from d&b.
Information regarding use of loudspeakers
WARNING
Never stand in the immediate vicinity of loudspea ers driven at a
high level. Professional loudspea er systems are capable of causing
a sound pressure level detrimental to human health. Seemingly non-
critical sound levels (from approx. 95 dB SPL) can cause hearing
damage if people are exposed to it over a long period.
In order to prevent accidents when deploying loudspea ers on the
ground or when flown, please ta e note of the following:
When setting up the loudspea ers or loudspea er stands, ma e sure
they are standing on a firm surface. If you place several systems on
top of one another, use straps to secure them against movement.
Only use accessories which have been tested and approved by d&b
for assembly and mobile deployment. Pay attention to the correct
application and maximum load capacity of the accessories as
detailed in our specific “Mounting instructions” or in our "Flying
system and Rigging manuals”.
Ensure that all additional hardware, fixings and fasteners used for
installation or mobile deployment are of an appropriate size and
load safety factor. Pay attention to the manufacturers instructions
and to the relevant safety guidelines.
Regularly chec the loudspea er housings and accessories for visible
signs of wear and tear, and replace them when necessary.
Regularly chec all load bearing bolts in the mounting devices.
CAUTION
Loudspea ers produce a static magnetic field even if they are not
connected or are not in use. Therefore ma e sure when erecting
and transporting loudspea ers that they are nowhere near
equipment and objects which may be impaired or damaged by an
external magnetic field. Generally spea ing, a distance of 0.5 m
(1.5 ft) from magnetic data carriers (floppy dis s, audio and video
tapes, ban cards, etc.) is sufficient; a distance of more than 1 m
(3 ft) may be necessary with computer and video monitors.

F1222
The F1222 is a compact, actively driven, 2-way full-range
loudspea er which uses a 12" LF driver and 2" HF compression
driver in an arrayable bass-reflex cabinet. The HF driver is coupled
to a 60
°
x 40
°
(hor. x vert.) constant directivity (CD) horn. As an
option the F1222 loudspea er can be equipped with a 90
°
x 40
°
horn.
The F1222 cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspea er cabinet is
fitted with a rigid metal grill, covered with a replaceable
acoustically transparent foam. The cabinet incorporates a pair of
steel handles, a pair of countersun M10 threaded inserts on the
top and bottom panels to accept stand adapters and mounting
frames. The top, bottom and rear panels of the cabinet also have
Ancra flying trac s to accept rigging hardware.
CAUTION
Only operate F1222 cabinets with a d&b D12 amplifier in
"2-Way Active" and F1222 mode or an A1 mainframe fitted with a
F1222 controller module, otherwise there is a ris of damaging the
loudspea er components.

Connector wiring
The F1222 cabinet is fitted with a single EP5 connector and uses the
pin assignments 1/2/3/4 and 5 (Pin 5: SenseDrive - D12 in
conjunction with 5-wire cables).
The F1222 can be supplied with a single CACOM connector as an
option to drive the F1222 cabinet with the d&b A1 mainframe.
SenseDrive is also available when the F1222 is driven by the A1
mainframe.

2-Way Active mode
Selecting "2-Way Active" and F1222 mode enables up to two
F1222 cabinets to be driven actively by the D12 amplifier.
The input signal is fed to INPUT A, while the input signal is routed
(lin ed) to INPUT B internally.
Controller settings
For acoustic adjustment the settings CUT, HFC and CPL can be
selected.
CUT
Set to CUT, the frequency and phase response of the F1222
loudspea er is modified for operation with d&b active subwoofers.
HFC circuit
Set to HFC (High Frequency Compensation), the level above 10 Hz
is raised to give a flat response up to 17 Hz.
CPL circuit
Frequency response of CPL circuit
The CPL (Coupling) circuit compensates for coupling effects
between the cabinets when building closely coupled arrays. CPL
begins gradually at 1 Hz, with maximum attenuation below
250 Hz, providing a balanced frequency response when the F1222
cabinet is used in arrays of two or more. The function of the CPL
circuit in the D12 amplifier is shown in the diagram opposite and
can be set in dB attenuation values between –9 and 0, or a positive
CPL value which creates an adjustable low frequency boost around
65 Hz (0 to +5 dB).

1222 controller rear panel
Two F1222 cabinets can be driven by a single A1 mainframe fitted
with a F1222 controller module.
CUT switch
The CUT setting is available. The characteristics of the CUT setting
is explained under the previous section "Operation with D12 -
Controller settings".
HFC switch
The HFC setting is available. The characteristics of the HFC setting
is explained under the previous section "Operation with D12 -
Controller settings".
1220 switch
The 1220 switch configures the controller module to drive existing
F1220 loudspea ers. This setting is identical to the standard setting
of the 1220 controller module.
Controller module rear panel
Two 8 pin, identically wired, CACOM output connectors (male) are
fitted to the module rear panel. To avoid a potential shoc hazard,
if a single F1222 cabinet is connected, the pins on the unused
soc et are internally isolated from the mainframe power amplifier
outputs.
Compatibility to 1220 systems
The F1222 cabinet uses a different 12“ low frequency driver to the
F1220. Both systems have identical power handling capacity and
acoustical quality. For sound reasons the F1222 cabinet should not
be driven with a 1220 controller.
