CONNECTIONS SETUP SUGGESTIONS

In normal operation (using the passive internal crossover), the 1/4" jacks and the Speakon™ Connectors are wired in parallel allowing any one of the connectors to be used as an input and any other as an output. This allows "daisy chaining" of multiple loudspeakers, eliminating the need for several long, cumbersome runs of speaker cable. During normal mode, the connections are as follows:

Polarity	Phone Jack	Speakon™
Positive (+)	Tip	1+ and/or 2+
Negative (-)	Sleeve	1- and/or 2-

When the switch on the back of the speaker is in the bi-amp mode, the internal crossover and high frequency attenuator are disabled. Thus, an external crossover must be used with the speaker and two channels of power amplification will be required: one for the low frequencies and another for the high frequencies. In bi-amp mode, the connections are as follows:

		Phone Jacks
Frequency	Polarity	Left	Right	Speakon
Lows	Positive (+)	N/A	Tip	1+
Lows	Negative (-)	N/A	Sleeve	1-
Highs	Positive (+)	Tip	N/A	2+
Highs	Negative (-)	Sleeve	N/A	2-

IMPORTANT: If the crossover switch is set to external, DO NOT plug a full range signal into the High Frequency input. Doing so will destroy the compression driver.

The placement of any speaker can dramatically affect its sound. Thus, there are several considerations to review when placing loudspeakers.

First, the range of the horizontal coverage should be determined. If the speaker will be used as a single unit, as part of a pair, or as part of a group of widely spaced enclosures, then maximum horizontal coverage will be desired. Examples of these types of setups are shown. No changes to the speaker are needed using these configurations. The horn in this configuration has a horizontal coverage angle of 90º and a vertical coverage of 40º.

If the speaker is part of a tightly packed array (see figure below), the coverage pattern should be modified to reduce overlapping radiating patterns of multiple drivers. (See the section on "Horn Inserts" for more information.)
