GRILLE MOUNTING POINTS

The grille is fastened to the enclosure with 1-1/2 in. / 38 mm #6

 

 

 

Phillips pan-head screws.

 

 

 

 

INPUT PANELS

 

 

 

 

 

 

 

 

 

INPUT PANEL

For connecting the power amplifier to the loudspeaker. Also has

 

 

 

user adjustable controls and PowerSense protection indicator.

 

 

 

 

 

 

 

POWERSENSEDDP 4 INDICATOR

This LED indicator lights red whenever the PowerSense DDP

 

 

 

circuitry operates. It indicates the loudspeaker is being overdriven.

 

 

 

 

 

 

 

HF LEVEL SWITCH

A 2-position switch used to adjust the volume level of the high

 

 

 

frequencies for more (+4 dB) or less (FLAT) output.

 

 

 

 

 

 

 

PASSIVE / BIAMP SWITCH

Used to select the loudspeaker’s operating mode. Down position

 

 

 

is for PASSIVE mode (single amplifier) and up position is for BIAMP

 

 

 

 

mode (separate LF and HF amplifiers).

 

 

 

 

Signal Input: 4 terminal NL4MP jacks. Accept NL4FC in-line

 

 

 

NEUTRIK SPEAKONS 5

connectors. Used for both PASSIVE and BIAMP modes. Use

 

 

 

terminals #1 +/- for PASSIVE mode or for BIAMP LF input. Use

 

 

 

 

terminals #2 +/- for BIAMP HF input (not used for PASSIVE

 

 

 

 

mode). The two jacks are in parallel. 6

11

DUAL 1/4 in. PHONE JACKS 5

Signal Input. Accepts 1/4 in. tip/sleeve (2 conductor) phone plug.

Tip = +, Sleeve = -. Use either jack for PASSIVE mode. Not used

 

 

 

 

for BIAMP mode. The two jacks are in parallel. 6

12

NEUTRIK SPEAKONS 5

Subwoofer signal input. Neutrik NL4MP jacks accept NL4FC in-

line connectors. Use terminals #1 +/-. Terminals #2 +/- are not

 

 

 

 

used. The 2 jacks are in parallel and in parallel with 1/4 in. jacks. 6

13

DUAL 1/4 in. PHONE JACKS 5

Subwoofer signal input. Accepts 1/4 in. tip/sleeve (2 conductor)

phone plug. Tip = +, Sleeve = -. The two jacks are in parallel

 

 

 

 

 

 

 

 

and in parallel with the Neutrik jacks. 6

 

 

 

1/4 in. PHONE JACK – HIGH PASS OUTPUT

High-pass output (150 Hz and above) for connecting a full-range

 

 

 

loudspeaker when using a single amplifier to power both the

 

 

 

 

 

 

 

 

 

 

 

 

subwoofer and full-range loudspeaker.

Footnotes for Physical Features

1Use ONLY for a horizontal pull direction, i.e. parallel to the enclosure surface where the insert is located. CAUTION: Refer to SECTION 7.4 for further information.

2These points are ONLY for supporting the loudspeaker from the bottom.

DANGER: These points are not intended nor load rated for suspending the loudspeaker.

3Vertical pull is perpendicular to the enclosure surface where the rigging point is located. Horizontal pull is parallel to the enclosure surface where the rigging point is located. CAUTION: Refer to SECTION 7.5 for further information.

4DDP = Dynamic Driver Protection

5Use either type of input jack - Neutrik or 1/4 in. Refer to SECTION 6.2 for further information.

6An unused Neutrik or 1/4 in. jack can be used as a signal output for paralleling to a 2nd loudspeaker. Refer to SECTION 6.3 for further information.
