The HDL 6-A Active Line Array Module from RCF is a 2-way active line array module designed for live sound reinforcement and installed sound applications. Powered by a 1400W 2-channel class-D amplifier, it features two 6" neodymium woofers for a solid bass reproduction and a 1.7" voice coil compression driver mounted on a precise 100 x 10° waveguide. The powerful DSP processes the sound including crossover, phase correction, limiting, and protection. The system accept female XLR input connectors and line-level signals from a mixing console or other signal source. The output XLR male connector provides a loop-trough for speaker's daisy chaining. The volume knob controls the volume of the power amplifier. The control ranges from maximum attenuation to the maximum level (maximum output).

Frequently Asked Questions
How many RCF HDL 6-A speakers do I need for my event?
The correct quantity depends on the width and depth of the audience, ceiling height, indoor or outdoor setting, stage location and required sound level. A compact event may use a smaller ground-supported configuration, while a deeper audience area may require additional modules, fills or delays. Northern Signal AV can recommend a system after reviewing your venue and attendance.
Does the RCF HDL 6-A require a subwoofer?
A subwoofer may not be necessary for speech, presentations or light background music in a suitable room. For live bands, DJs, concerts, dance events and bass-heavy music, adding subwoofers is strongly recommended. The HDL 6-A’s published frequency response begins at 65 Hz.
Can the RCF HDL 6-A be ground-stacked?
Yes. The HDL 6-A supports different deployment options using compatible RCF mounting and stacking accessories. The correct configuration will depend on stage height, audience position and venue restrictions.
Can the RCF HDL 6-A be flown?
The HDL 6-A can be flown with compatible RCF fly bars and rigging accessories. Flown systems must be designed and installed by qualified personnel, with venue approval and appropriate structural documentation.
Is the RCF HDL 6-A suitable for weddings and corporate events?
Yes. Its compact cabinet, wide horizontal coverage and strong vocal intelligibility make it suitable for weddings, galas, conferences, awards ceremonies and corporate presentations. The system can be scaled and visually positioned according to the venue.
Is the RCF HDL 6-A suitable for concerts and live bands?
Yes. Multiple HDL 6-A modules can form a scalable professional PA system for live music. For full-band performances, the system should normally be paired with appropriately sized subwoofers, stage monitors, microphones, a digital console and an experienced sound technician.
Can Northern Signal AV deliver and set up the system?
Delivery, setup, system tuning and technical support can be added to the rental package. Northern Signal AV also offers complete production support when an event requires audio, video, lighting, staging or onsite technicians.
Can the HDL 6-A be used outdoors?
It can be used for temporary outdoor productions when the system has proper weather protection, safe electrical distribution and an approved ground-support or rigging plan. The speakers should not be directly exposed to rain, snow or uncontrolled moisture.
