Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. This amplifier module deliver a ultra-fast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. The amplifier present SMPS power supply section to produce maximum output and minimum weight.The processing includes cluster and HF projection correction and special new presets for indoor and high curving situations.

1.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.
2.LINK XLR OUTPUT.The output XLR male connector provides a loop trough for speakers daisy chaining. 3.VOLUME.Controls the volume of the power amplifier. The control ranges from - (maximum attenuation) to the MAX level ∞ (maximum output). 4.POWER INDICATOR.Power on indicator. When the power cord is connected and the power switch is turned on this indicator lights green. 5.SIGNAL INDICATOR.The signal indicator lights green if there is signal present on the main XLR input. 6.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. |
| 7.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). 8.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). 9.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 H20-A). |

10.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). 11.AC POWERCON RECEPTACLE. Uses a POWERCON locking 3-pole AC mains. Always use the specific power cord provided in the package. 12.AC POWERCON LINK RECEPTACLE. Use this receptacle to link one or more units. Always make sure that the maximum current requirement does not exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF SERVICE CENTRE. 13.POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that the VOLUME is set to - when you turn on the speaker. 14.FUSE |
