- Step-by-step fixGet the fix →
which transmitters officially fit the Beltpack Module (Shure ULXD1, QLXD1, Sennheiser SK 100 G4 etc.)
Likely cause: Only listed packs are tested for fit, weight and lock retention.
- Step-by-step fixGet the fix →
Beltpack Module no audio / dead mic, transmitter shows on
Likely cause: The capsule contains active electret elements and the Automute circuit, powered by the Module AA; the transmitter only carries the signal over RF.
- Step-by-step fixGet the fix →
Beltpack Module too quiet / feedback / loud pop at switch-on
Likely cause: Gain staging happens entirely in the third-party system; the Module is a passive-level capsule with Automute.
- Step-by-step fixGet the fix →
do I need a frequency license for the Beltpack Module / what is the range
Likely cause: The Module only supplies a mic signal to the transmitter's input.
- Step-by-step fixGet the fix →
generic TA4F lav cable into Beltpack Module — low/no audio
Likely cause: The Shure TA4F mic input expects a specific bias/load network; the Catchbox cable provides it.
- Step-by-step fixGet the fix →
how to clean Beltpack Module cover / can I machine wash it
Likely cause: Heat above 50 °C damages the magnetic lock; water damages electronics.
- Step-by-step fixGet the fix →
Beltpack Module mic cuts out when thrown / goes silent when passed around
Likely cause: Automute is in the Module capsule, independent of the transmitter's own mute switch, so the transmitter still shows RF/audio link while audio is muted.
- Step-by-step fixGet the fix →
what connector does my beltpack use — which Catchbox adapter cable to order (AKG, MIPRO, Lectrosonics, Audio-Technica, Sony)
Likely cause: Each brand's pack takes a brand-specific connector and pinout; the Catchbox cable has to match it at the transmitter end.
- Step-by-step fixGet the fix →
Beltpack Module vs Catchbox Mod — are they the same / do parts swap?
Likely cause: Different generations with different cable terminations and cavity size.
- Step-by-step fixGet the fix →
beltpack transmitter won't fit in the Beltpack Module / cover won't close
Likely cause: Fit is limited by the cavity depth and connector/antenna clearance.
- Step-by-step fixGet the fix →
which adapter cable for my beltpack / Shure TA4F lav pack into Beltpack Module
Likely cause: The Module end is 3.5 mm TS; the transmitter end must match that brand's mic-input connector and pinout.
