d&b SenseDrive

The SenseDrive feature within D12 amplifiers enables electrical

compensation for the properties of the loudspeaker cable used.

SenseDrive requires an additional sense wire. SenseDrive is

therefore only available with EP5 connectors and 5-wire cabling

for applicable loudspeakers.

Note: When the D12 is operated in "Mix TOP/SUB mode",

the SenseDrive function is only available at the output B

connector.

In permanent installations, SenseDrive can also be applied to

cabinets with NL4 connectors or the fixed cable option (PG). The

connection of the negative signal wire (EP5 pin 4 of the respective

D12 output) to the SenseDrive wire (EP5 pin 5 of respective D12

output) is made in a breakout box close to the loudspeaker

cabinet. For an uncompromising SenseDrive performance the

connection should be done not more than 3 m (10 ft) away from

the loudspeaker.

2.3 Operation

NOTICE!

Only operate d&b loudspeakers with a correctly configured d&b

amplifier, otherwise there is a risk of damaging the loudspeaker

components.

Applicable d&b amplifiers:

30D/D12/D20/D80.

Application

Setup

Vi-SUB

V-SUB

Within applicable d&b amplifiers, the controller setup is available

in Dual Channel or Mix TOP/SUB mode.

For acoustic adjustment the 100 Hz mode can be selected.

100 Hz mode

With the 100 Hz mode selected, the upper operating frequency of

the system is reduced from 115 Hz to 95 Hz.

It can be used when actively driven Vi subwoofers are used to

supplement Vi cabinets operated in full range mode. The 100 Hz

mode can also be used to compensate for the effect of close

coupling between the Vi-SUB and Vi cabinets operated in CUT

mode. With Ti cabinets the standard mode is recommended.
