ENGLISH

MAIN XLR INPUT (BAL/UNBAL). The system accept male XLR/Jack input connectors

with line level signals from a mixing console or other signal source.

LINK XLR OUTPUT. The output XLR male connector provides a loop trough for

speakers daisy chaining.

VOLUME. Controls the volume of the power ampliﬁer. The control ranges from -

(maximum attenuation) to the MAX level ∞ (maximum output).

POWER INDICATOR. Power on indicator. When the power cord is connected and

the power switch is turned on this indicator lights green.

SIGNAL INDICATOR. The signal indicator lights green if there is signal present on

the main XLR input.

LIMITER INDICATOR. The ampliﬁer has a built in limiter circuit to prevent clipping

of the ampliﬁers or overdriving the transducers. When the peak clipping circuit is active

the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks

frequently or lights continuously, turn down the signal level. The ampliﬁer has a built

in RMS limiter. If the RMS limiter is active the LED lights red. The RMS limiter has the

purpose to prevent damages the transducers. The speaker shall never be used with

the limit indicator red, continuous operation with the RMS protection active can cause

damages to the speaker.

HF. The switch gives the possibility to set high frequencies correction depending on

target distance (air absorption correction):

- NEAR (used for pole mount applications or near ﬁeld)

- FAR (for farthest ﬁeld).

CLUSTER. The combination of the 2 switches gives 4 possibilities of mid low

frequencies correction depending on cluster size.

- 2-3 modules (used for pole mount applications ground stacking)

- 4-6 modules (small ﬂown systems)

- 7-9 modules (medium ﬂown systems)

- 10-16 modules (maximum ﬂown conﬁguration).

HIGH CURVING. The switch gives the extra possibility to boost mid frequencies

depending on a high curving cluster conﬁguration of few pieces.

- OFF (not active correction)

- ON (for high curving arrays of few pieces HDL20-A or HDL10-A).

INDOOR. The switch gives the extra possibility to set low frequencies correction

depending on a indoor/outdoor use, in order to compensate room reverberation on

lows.

- OFF (not active correction)

- ON (correction for reverberant indoor rooms).
