RDL DB-CIJ3D Consumer Input Jacks, Stereo Outputs, Black

For security, surveillance and pro AV installations that require reliable, hum-free audio integration, the Radio Design Labs DB-CIJ3D consumer input jacks provide a simple, professional solution. This faceplate module passively mixes two unbalanced line-level sources and converts them to a balanced line output—without added gain—making it ideal for feeding control room mixers, DVRs or monitoring equipment. Stereo inputs are provided on both RCA jacks and a stereo 3.5 mm mini-jack for maximum source flexibility, while transformer isolation and hum-cancellation protect sensitive surveillance and monitoring systems from ground-loop noise. The DB-CIJ3D’s line-level output is engineered to drive 10 kΩ equipment inputs and connects via a detachable terminal block for quick wiring during installs. Finished in discreet black and sized for standard mounting, this Radio Design Labs module integrates cleanly into racks, wall plates and junction boxes in retail, security, conferencing and broadcast environments. Add the DB-CIJ3D to your next installation to simplify audio routing and improve signal integrity—perfect for control rooms and monitoring stations.
