Black cylindrical barrel adapter with TB5M connector for lavalier microphones

PSC

PSC Lavalier Power Supply Barrel Adapter TB5M 2-Wire Positive Bias

SKU CH-DCE7-RKEQP

Converts 12, 12PH or 48PH phantom power to lavalier voltage via TB5M 2-wire positive bias connector

  • Powers lavalier mics from mixers with condenser powering
  • Converts 12T, 12PH, or 48PH power to suitable voltage
  • TB5M 2-wire positive bias for direct hardwired connection
  • Compact barrel design fits tight recording rigs
  • Durable construction for reliable long-term use

Universal Lavalier Power Adapter

The PSC TB5M 2-Wire Positive Bias adapter connects lavalier microphones to mixers and recorders that provide condenser microphone powering. It converts 12T, 12PH, or 48PH phantom power down to the voltage required by most lavalier capsules. The compact barrel design suits mobile recording rigs and fixed studio installations alike.

Sustained Session Reliability

During long recording sessions the adapter maintains a steady voltage conversion without drift or intermittent contact. Its hard-wired construction avoids the loose connections that can develop with plug-in alternatives over hours of use. The robust housing protects the internal circuitry from cable strain and accidental knocks.

Thermals, Noise and Power Draw

The passive circuit draws only the phantom current supplied by the mixer or recorder, adding no audible self-noise to the signal chain. No active components generate heat, so the barrel remains at ambient temperature even during continuous operation. Power consumption is limited to the microphone's own requirements.

Questions about this item

Does the TB5M 2-Wire adapter generate any audible noise when powering a lavalier mic all day?

The passive barrel adapter contains no active circuitry, so it adds no electrical noise or heat during continuous use.

What mixer or recorder phantom power settings must I already have to use this adapter?

The unit accepts 12T, 12PH or 48PH condenser microphone power from the host device and converts it to the voltage the lavalier requires.

Will the adapter work with older lavalier microphones that need a lower bias voltage?

Yes, it steps down 12 V or 48 V phantom power to the positive bias voltage used by most legacy lavalier capsules.
