Qi-SUB/QiCSA-SUB Manual

Connections

The Qi-SUB is supplied with two NL4 connectors. All pins of both

connectors are wired in parallel. The Qi-SUB uses the pin assignments

2+/2–. Pins 1+/1– are designated to Qi-Series full range systems.

Using one connector as the input, the second connector allows for direct

connection to additional loudspeakers.

In case of the QiCSA-SUB the front grill of the cabinet baffle is fitted

with a single NL4 connector located at the bottom left hand side of the

grill.

Installation loudspeakers with the weather resistant option are supplied

with a fixed cable (PG).

Cable type:

Standard length: 5.5 m (18 ft)

Pin equivalents of NL4 connectors and the fixed cable option (PG) are

listed in the table below.

Connecting D12 EP5 outputs to installed loudspeaker

cabinets (SenseDrive)

To apply SenseDrive for the subwoofer, D12 amplifiers with EP5

connectors have to be used.

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

function is available on the output B connector only.

In permanent installations SenseDrive can also be applied to cabinets

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

2-wire cable

NL4 /

(max. 3 m /10 ft)

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

–

junction 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.
