The Dynacord Cobra-4 is a compact 4-way line-array system designed for medium-to-large venues, capable of projecting sound up to 80 meters. When paired with Dynacord H5000 amplifiers, the system utilizes high-efficiency Class H topology and advanced DSP to ensure maximum dynamic range and speaker protection.
Dynacord Cobra-4 System Components:
A standard configuration, often sold as the COBRA-4 PH package, typically includes a mix of nearfield and farfield cabinets to provide even coverage across an audience.
- Dynacord COBRA-4-TOP: An active 3-way nearfield cabinet. According to Artsound, it features a 15-inch Electro-Voice DL15Y woofer, four C8 conical midrange horns, and a DH 2T titanium high-frequency driver.
- Dynacord COBRA-4-FAR: An active 3-way farfield cabinet. It shares the same low and mid components as the TOP but uses a specialized 3-driver high-frequency line array for increased throw.
- Dynacord COBRA-PWH: A planar waveguide horn subwoofer. It is equipped with an 18-inch Electro-Voice EVX 180B transducer for deep, penetrating bass.
Dynacord H5000 Power Amplifier:
The Dynacord H5000 is a high-performance amplifier from the PowerH series, specifically designed for professional touring and concert applications.
- Power Output: According to musicstore.com, it delivers 2 x 2500 Watts at 4 Ohms and can handle 2 x 3500 Watts at 2 Ohms.
- Efficiency: It uses a 3-stage Grounded Bridge Class H topology with a “floating” switching power supply, which Artsound notes offers high output at a minimum weight of 14.5 kg.
- Protection: The unit includes integrated audio limiters, thermal protection, and DC/HF short circuit safeguards.
- Control: Often used with RCM modules (like the RCM-26) to allow for remote monitoring and advanced DSP control via IRIS-Net software.
System Performance and Specifications:
- Coverage: The system is designed to provide optimal line-array performance without extensive manual configuration. At a distance of 30 meters, it can produce average SPLs of 110 dB in the mid-high range and 120 dB in the bass.
- Frequency Response: The overall system response ranges from 32 Hz to 20,000 Hz.
- Protection Circuitry: All cabinets feature “Voice Coil Tracking Protection,” which simulates thermal behavior to prevent speaker damage without audible clicks or pops.
