The HDL 38-AS is the ideal flyable bass complement for the HDL 30-A array system. It features one 4.0” voice coil, 18” Neodymium woofer to handle 136 dB SPL Max from 30 Hz to 140 Hz with the maximum linearity and low distortion. The HDL 38-AS is perfect to create flown systems for theatrical and indoor requirements. The built-in 3200W class-D amplifier delivers excellent playback clarity and up to 136 decibels SPL max. Due to its compatibility with RDNet – remote monitoring and control, the HDL 38-AS is part of the professional HDL System.

• 136 dB Max SPL
• 3200W peak class-D Amplifier
• 30-140 Hz frequency response
• RDNet Networked Management
• 1×18” Neodymium Woofer, 4.0” voice coil

RCF RDNet

Networked control and much more

RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.

Powerful class D amplifiers

RCF’s Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. HDL amplifiers 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. All the HDL amplifiers present SMPS power supply section to produce maximum output and minimum weight.

Precision transducers

Our latest developments have resulted in designing state of the art neodymium magnetic circuits, radically new voice coil ventilation systems and ground-breaking direct drive voice coil assemblies.
