The Calrad 15-132 is a passive, parallel-wired headphone junction box. It features 1 x Female XLR and 1 x 1/4" input/thru-jacks, routing the signal equally to six 1/4" headphone outputs without altering the overall input signal.Review the specifications and routing using the Calrad Electronics Catalog.Specifications & RatingsInputs: 1x 3-Pin Female XLR, 1x 1/4" TRS (Stereo/Mono)Outputs: 6x 1/4" TRS Female JacksThru/Daisy-Chain: 1x Side-Mounted 1/4" JackImpedance: 8 Ω to 600 ΩPower Capacity: 50W MaximumWiring & Schematic BreakdownBecause the 15-132 is a passive distribution box, its internal schematic relies on a straightforward parallel resistor/signal routing network:Signal Flow: The Input Signal (from the XLR or first 1/4" jack) passes through a parallel resistor network. This drops the signal level and provides uniform volume and impedance matching for multiple sets of headphones.Daisy-Chaining: The side-mounted 1/4" jack is wired directly in parallel with the inputs, allowing you to bridge signals to a second Calrad 15-132 box.Outputs: The six 1/4" jacks are wired in parallel to the distribution network.Tip: Left Channel AudioRing: Right Channel AudioSleeve: Common Ground.
