CAYMON CASY module with female XLR connector CASY121/B

The CAYMON CASY module with female XLR connector CASY121/B is a rack-mountable audio module designed to provide a standard, balanced XLR interface for microphone or line-level signals. It is intended for installation in modular patch panels and equipment racks to enable secure, low-noise connections and straightforward signal routing in live sound, studio, and installation environments.

Advantages

This module offers a compact, standardized XLR female connector in a format compatible with modular rack systems, ensuring consistent contact quality and reliable mechanical retention. Its balanced connection reduces susceptibility to electromagnetic interference and signal degradation over cables. The module’s form factor simplifies wiring and maintenance within patch panels and rack assemblies.

Suitable for

• Microphone connections in live sound and rehearsal rigs
• Line-level connections for outboard gear in studio patch bays
• Fixed AV installations and conference rooms
• Equipment racks requiring modular input/output access

Key specifications

• Connector type: female XLR, 3-pin, balanced
• Intended signal: microphone and line-level audio
• Mounting: modular rack/patch panel module format
• Mechanical retention: standard XLR locking mechanism
• Construction: metal housing compatible with rack installation

How to use

Install the CASY121/B module into a compatible modular patch panel or rack frame according to the rack manufacturer’s instructions. Terminate the rear contacts or wiring to the panel’s internal cabling or terminal points following standard audio wiring practices for balanced connections: pin 1 = ground/shield, pin 2 = hot (+), pin 3 = cold (−). Connect microphones, DI boxes, or line-level sources to the front XLR female connector; ensure connectors are fully seated to engage the locking mechanism.

Usage recommendations

For lowest noise and best performance, use balanced XLR cables of good quality and maintain proper cable dressing inside the rack. Verify correct pin wiring when integrating with other equipment to avoid phase or grounding issues. For permanent installations, secure wiring and use strain relief to reduce mechanical stress on the module and connected cables.
