The Meyer Sound D-2 Control Electronics Unit is a dedicated single-channel analog processor specifically used for the Meyer Sound DS-2 mid-bass loudspeaker.
Unlike the LD-2 (which is a general-purpose line driver for various Meyer systems), the D-2 is a factory-aligned, specialized controller.
Specific Usage & Speakers
- Primary Speaker: It is designed to operate exclusively as part of a system with the DS-2 (or the horn-loaded DS-2P) mid-bass cabinet.
- System Role: One D-2 unit is required per channel of DS-2 loudspeakers.
- Signal Chain: It is intended to be the final component in the signal chain before the power amplifier (historically paired with Crest Audio amplifiers in professional touring racks).
Core Functions for the DS-2
- Active Crossover: It provides the specific crossover networks required for mid-bass reproduction.
- Alignment: It includes factory-pre-set frequency and phase response alignment circuitry tailored to the DS-2’s horn design.
- SpeakerSense™ Protection: It features L-Acoustics’ proprietary driver protection, which uses “sense” lines from the amplifier to provide:
- RMS signal limiting (for thermal protection).
- Peak signal limiting (for protection against instantaneous spikes).
- Excursion protection (to prevent mechanical damage to the woofer).
