3-pin Mini-XLR (Switchcraft Tini-QG) connector

Switchcraft identifies this Tini-QG product as a Mini-XLR connector with 3 conductors.

Also called Mini-XLR 3 3-pin Mini XLR Tini-QG 3-pin

Mini-XLR family name and conductor count identify a connector form; they do not establish the connected device signal, power scheme or contact assignment.

Look for

Confirm the compact Mini-XLR/Tini-QG form and 3-conductor variant; do not substitute it for full-size XLR or infer a wiring scheme from pole count.

Is a Mini-XLR cable automatically an XLR adapter?

FIELD NOTES 04

TA3MLX identifies a specific three-conductor male Mini-XLR component. It does not specify the circuit inside a microphone, receiver or recorder.

Identify first

Read the part and the device.

The short metal barrel and black handle belong to the named example, not every Mini-XLR variant.

Still unresolved

Keep this requirement open.

A full-size-XLR conversion and the required signal wiring are unknown without equipment documentation.

Not established · named example only

Does matching contact count establish a full-size/Mini-XLR cable?

Unknown: component identity does not specify either device’s circuit.

Boundary. No pin mapping, bias voltage or microphone compatibility has been invented.

Next check. Find the equipment maker’s model-specific cable or wiring documentation.

S028 · S350 · C026C (private workspace) · C309C (private workspace)

Before choosing an adapter or reader

  1. Confirm the manufacturer series and exact part.
  2. Record both equipment models.
  3. Check a model-specific cable recommendation before connecting.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or component documentation.
  2. Keep physical form, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire, adapt or install from this recognition record; resolve the remaining requirements first.

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized-work procedure or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
