B1-SUB
The B1-SUB is an actively driven subwoofer which uses a pair of
15" LF drivers mounted in a bass reflex cabinet.
The cabinet is constructed from marine plywood coated with an
impact resistant paint. Fitted to the cabinet sides are recessed
handles and rigging stud plates. On the front is a rigid steel grill
with an acoustically transparent foam cover. Catches to secure an
optional protective transport cover are also fitted to the top and
bottom front edges of the cabinet. Heavy duty wheels are fitted on
the back panel along with ratchet strap guides and countersunk
four M10 threaded inserts for attaching safeties and additional
rigging.
The frequency response of the B1-SUB extends from 32 Hz to 110
Hz. The B1 generates a warm, low bass - ideal for use with the
1220 system.
The B1-SUB can also be used as an F2 system subwoofer. For a
well balanced sound at full output, two B1-SUBs to each F2 should
be used. The dimensions, shape and the fittings used on the B1-SUB
cabinet match those of the F2 cabinet making it particularly easy to
deploy a mixed F2/B1 system - stacked or flown.
B1-CO - Controls & indicators
Since the B1-CO controller module is not fitted with any special
controls or configuration switches, its standard controls are
covered in the general controller module description in Section 3.2
of the A1 user manual. Please also refer to the descriptions of the
1220 and F2 systems for recommended subwoofer level settings.
Controller module rear panel
A single 8-pin CA-COM output socket is fitted to the module rear
panel.
