Product Overview & Key Specifications

The CM-2 CobraNet Replacement Module is a high-reliability, 100% pin-compatible drop-in replacement card designed to restore end-of-life (EOL) CobraNet audio infrastructure.

Built on a modern 4-layer PCB with premium passive components, each module is populated with original, fully tested Cirrus Logic CS181022 (16x16 channels) or CS496112 (8x8 channels) DSP silicon. It provides an immediate, plug-and-play solution for venues seeking to keep legacy mainframes running without multi-million-dollar system overhauls.

Compatible Legacy Systems 

Our CM-2 replacement modules offer native hardware and protocol compatibility with major legacy CobraNet audio platforms, including:

• Biamp Systems: AudiaFlex, AudiaFusion CobraNet cards

• Peavey MediaMatrix: CAB 4, NION, and legacy mainframe expansion cards

• Crown Audio: CobraNet-enabled PIP modules and amplifiers

• Yamaha: Legacy Mini-YGDAI CobraNet interface cards

Key Technical Features

• 100% Hardware & Pin Compatibility: Matches the exact physical footprint and pinout of original factory CM-2 boards. Simply pull the non-working module and insert our board.

• Native Software Discovery: Instantly detected by CobraNet Discovery (CN-Disco) software, HMI management tools, and host system CPUs.

• New PCB + Genuine Silicon: Uses a modern, cool-running 4-layer circuit board populated with 100% authentic New Old Stock (NOS) / pull-tested genuine Cirrus Logic DSP chips.

• Mission-Critical Burn-In Tested: Every unit undergoes 24-hour continuous signal pass-through and thermal stress testing prior to shipment.

Frequently Asked Questions (FAQ)

Q: Is this CM-2 module a brand-new product?

A: Yes. The PCB, power regulation, passive components, and headers are 100% brand-new. Because Cirrus Logic officially discontinued (EOL) the CS181022 and CS496112 ICs, the DSP cores are 100% authentic, pull-tested genuine Cirrus Logic chips verified for perfect functionality.

Q: Do I need to modify software configurations when replacing a broken CM-2?

A: No. Our module behaves identically to the original factory CM-2 module. Your mainframe and CobraNet Discovery software will recognize it natively with zero software hacks required.

Q: What is the difference between the CS181022 and CS496112 versions?

A: The CS181022 version supports up to 16x16 audio channels (8 duplex bundles), while the CS496112 version supports up to 8x8 audio channels (4 duplex bundles). Both feature identical physical pinouts.
