Guide note · not an individual product specification
The useful distinction
Understand the requirement.
Keep conversion roles and unresolved specifications visible in a handoff. [C154A]
ProDI features describe a balanced microphone-level XLR output; the publisher’s two pages disagree on output impedance. [C154B]
Bounded facts, visible unknowns
Specifications and limits
Direct boxes, source conflicts and audio patch reports facts and limitations
Workflow boundary
Scoped analog audio documentation; not wiring or compatibility approval. [C154A][C154B]
Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
The ProDI features and specification pages give different output-impedance figures. The record preserves the conflict and does not select one for a numerical matching claim. A fresh source inspection date cannot resolve contradictory documentation.
Before you connect
What to check
Identify the exact device and port.
Keep shared channels and controls explicit.
Retain unknown power, mode and cable observations.
A report captures selected public models, endpoint roles, anonymous unit numbers, explicit observations, allocation findings and supporting sources. It contains no personal inventory or saved notes. It is a read-only reference, not an editable workspace backup.
Reprepare after changes
Changed inputs, relevant public evidence, dataset identity or assessment date invalidate the report. Export and print require a current prepared preview. A report cannot certify hardware, safe power switching, cable wiring or the whole audio system.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.

ProDI specifications identify a mono passive transformer device requiring no power.
Locator: Audio circuit, channel count, input/output connectors and general power Access: public page. Output impedance conflicts with the same publisher’s features page. No numerical impedance is selected as authoritative.
Locator: Audio circuit, channel count, input/output connectors and general power Access: public page. Output impedance conflicts with the same publisher’s features page. No numerical impedance is selected as authoritative.
Locator: Instrument input, thru, balanced output and ground lift Access: public page. Features state 600 ohms while specifications state 150 ohms for output impedance. Both remain a review issue; no electrical matching calculation uses either value.

ProDI specifications identify a mono passive transformer device requiring no power.
Claim scope: Exact-model analog audio reference; no end-to-end compatibility or electrical approval.
Recorded evidence only. An inspection date, publisher label, source link or generated packet is not independent technical review, hardware testing, fabrication approval or a compatibility verdict.
