Connections

Power Connection

This is a standard 3-prong IEC power connector. Connect the detachable power cord (included in the packaging with the loudspeaker) to

the power receptacle and plug the other end of the power cord into an AC outlet.

• Make sure that the AC power is matched to the AC power indicated on the rear panel (below the IEC receptacle)

• Disconnecting the plug’s ground pin is dangerous. DOT NOT disconnect.

XLR and 1/4" Combo Inputs

Both input channels may accept a balanced mic signal using an XLR connector. They are wired as follows, according to standards speciﬁed

by the AES (Audio Engineering Society).

XLR Balanced Wiring:

• Pin 1 = Shield (ground)

• Pin 2 = Positive (+ or hot)

• Pin 3 = Negative (– or cold)

In addition to accepting a balanced mic signal using an XLR connector, these input channels may also accept 1/4" line-level signals driven

by balanced or unbalanced sources.

Additionally, both input channels may accept Hi-Z sources (such as guitars) via the 1/4" input without the need for a separate DI box.

To connect balanced lines to these inputs, use a 1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve, the three connection

points available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and are wired as follows:

1/4" TRS Balanced Mono Wiring:

• Sleeve = Shield

• Tip = Hot (+)

• Ring = Cold (–)

To connect unbalanced lines to these inputs, use a 1/4" mono (TS) phone plug, wired as follows:

1/4" TS Unbalanced Mono Wiring:

• Sleeve = Shield

• Tip = Hot (+)

Mix Out

This is a male XLR-type connector that produces the mix of the three input channels determined by the level and EQ settings entered. Use

it to daisy-chain several BlacklineX Powered loudspeakers together off the same signal source(s).

They are wired as follows, according to standards speciﬁed by the AES (Audio Engineering Society):

Balanced XLR Output Connector:

• Pin 1 – Shield (ground)

• Pin 2 – Positive (+ or hot)

• Pin 3 – Negative (– or cold)
