Q-SUB Manual

Q-SUB

The Q-SUB is the subwoofer for the Q-Series. It can be used to
supplement Q1 and Q7 cabinets in various combinations, either flown or
ground stacked. The Q-SUB cabinet is an actively driven bass-reflex
design housing a long excursion 18" driver, its frequency response
extending from 40 Hz to 130 Hz.
The Q-SUB cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill, covered with a replaceable acoustically
transparent foam. The cabinet incorporates a pair of handles, and
mounted on the rear panel are two EP5 or NL4 connectors wired in
parallel and four heavy duty wheels. An M20 threaded flange in the top
panel accepts the d&b Z5013 Loudspeaker stand for the deployment of
full range cabinets.
The Q-SUB has a total of 10 sockets in the front grill and side panels to
accept the Z5153 Locking pins 8 mm that connect to the array links of
the Q1 system. Two runners extend from the rear to the front panel of
the cabinet protecting the bottom panel against scratching. Two
correspondingly shaped recesses are incorporated in the top panel of
each cabinet that accept these runners to prevent cabinet movement
when stacking Q-SUBs.
NOTICE:
Only operate Q-SUB loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

Connections

The Q-SUB cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The Q-SUB uses the pin
assignments 3/4 and 5. Pin 5 is used for SenseDrive (only available
when using a D12 amplifier and 5-wire cabling). Pins 1/2 are designated
to Q-Series full range systems. Using the male connector as the input,
the female connector allows for direct connection to additional
loudspeakers.
The Q-SUB can be supplied with NL4 output connectors as an option.
The D12 SenseDrive function is not available when using NL4
connectors. Pin equivalents of EP5 and NL4 connectors are listed in the
table below.
