INTRODUCTION

The Coda Audio award winning sensor controlled technology is extended with the SCP-Series subwoofers. Combining a closed feedback-loop control with large, low noise laminar flow ports the SCP-F subwoofer offers increased output and well controlled response. This technology surpasses that of conventional subwoofers offering measurable and clearly audible advantages in the impulse response, group delay, waterfall and the distortion domain. In fact the range 35 – 100 Hz is time aligned while the group delay increases slightly in the range 25 – 35 Hz. The reduced group delay results in extremely accurate and musical bass reproduction. The sound quality is far beyond that of conventional port loaded systems.

APPLICATION

The SCP-F is perfectly suited as a subwoofer for G700-Series and CUE-Series, extending the system performance down to 25Hz. SCP-F is also an addition to AiRAY High Output line array systems. Typical applications are touring sound, theaters, houses of worship, dance clubs and live sound venues.

DESCRIPTION

The SCP-F is a sensor controlled subwoofer incorporating double 18” woofers in a compact, vented enclosure.
The drivers contain an integrated velocity sensor that measures the diaphragm movement in real time, compares it with the input audio signal and adjusts the amplifier driving voltage and/or current, correcting any driver inaccuracy. It is a self-optimizing, closed feedback-loop in which the driver confirms precisely the power it needs to accurately reproduce the original audio signal. The key advantage is a very extended and controlled response. Any distortion produced by the driver or the enclosure is instantly corrected by the feedback.

TRANSDUCERS

The SCP-F is equipped with two extremely long excursion 18” neodymium ultra low distortion woofers with integrated velocity sensor that measure, compare and control cone movements. The neodymium motor delivers extreme high magnetic flux for increased efficiency. The 4” voice coil is 50 mm high, ensuring ultra linear excursion of 40 mm / pp at consistent magnetic force. State of the art carbon-fiber cone ensure maximum stiffness and low moving mass. Three aluminum shorting rings reduce inter-modulation distortion; minimize induction variation while reducing thermal compression. This design reduces dramatically the distortion of a typical subwoofer at longer excursion levels, and improves the overall sound quality and performance characteristics of the cabinet. The sensor is in fact an additional voice coil connected to the loudspeakers voice coil in a high precision, magnetically shielded system.

ELECTRONICS AND CABLING

Using the Comparator
The Coda Audio LINUS10 DSP amplifier provides integrated power and feedback loop control solution for the SCP-F subwoofer. The unit has two amplifier channels as well as two comparators connected to a 5-pol Neutrik XLR input. The Comparator’s electronic circuit loop measures the voice coil excursion of the driver and corrects the signal, significantly decreasing distortion. The unit is set for flat frequency response down to 25 Hz (-6 dB).

Rigging Hardware

The SCP-F includes flying hardware for easy flying or ground stacking in various combinations.
