WL2082-i Controls and Connections

MODE Selection Switch

BI AMP: When set to BI AMP, an internal shading net- work removes the mid-frequencies from one of the low- frequency drivers. The BI AMP HORIZONTAL SHADING switch will select which transducer is shaded.

TRI AMP: Shading network is NOT applied (shading must be provided by upstream signal processing). The Bi Amp Mode Horizontal Shading selector switch is not functional in tri amp mode. Connect to the Speakon as shown for tri amp.

BI AMP MODE HORIZONTAL SHADING Selection Switch

The BI AMP MODE HORIZONTAL SHADING selection switch is only functional in bi amp mode. This switch determines which low-frequency transducer receives only low-frequency program material (shading). The un- shaded transducer receives low- and mid-frequency program material. This allows switch position selection for use as either “house left” or “house right”, without the need to flip boxes.

NOTE: LEFT and RIGHT markings on the BI AMP HORIZONTAL SHADING SWITCH apply to the enclosure as viewed from the rear (i.e. looking at the Input Plate with the text prop- erly oriented).

LEFT: Use this setting to steer coverage to the left (as viewed from behind the arrays, looking toward the audience).

RIGHT: Use this setting to steer coverage to the right (as viewed from behind the arrays, looking toward the audience).

Input Connections

The WL2082-i input connectors are a pair of Neutrik NL8's wired in parallel. Connections for biamp and tri- amp vary, see Table 2 or the pinout table on the WL2082-i input plate (Figure 19).

The WL2082-i loudspeaker is not equipped with a crossover network. All signal pro- cessing must be done before connecting audio power to the loudspeaker. Do not con- nect full-range audio to the high-frequency transducer or damage may result!
