5.0 Function and Routing Controls
The T12 Mic Preamp is equipped with a flexible set of preamp functions and routing controls. Functions
include a polarity inverter, 48-volt phantom power, -20dB pad, and input selector. These features
provide increased control of the input signal arriving at the preamp.
5.1 Polarity Inverter (POL)
The T12 Mic Preamp is equipped with an input polarity inverter (POL), sometimes referred to as a
“phase reverse” or “Ø” switch. The POL switch flips the polarity of the input signal before the preamp
stage.
POL: Engage to activate the polarity inverter
• Applies to the HI-Z and MIC inputs
• Illuminates when engaged
5.2 48-Volt Phantom Power
The T12 Mic Preamp can supply 48-volt phantom power to the microphone INPUT.
48V: Engage to apply 48-volt phantom power to the microphone INPUT
• Illuminates in red when engaged
NOTE: CAUTION! Only engage the 48V switch when microphones that require 48-volt phantom
power are connected. Phantom power will damage many ribbon mics, especially vintage
ribbon mics, so use great care when engaging 48V phantom power.
NOTE: CAUTION! Never connect or disconnect microphones when 48-volt phantom power
(48V) is engaged. Wait 5-10 seconds after the 48V switch is disengaged for the circuit to
discharge before disconnecting microphones.
5.3 -20dB Input Pad
The T12 Mic Preamp is equipped with a -20dB input pad (PAD -20) before the preamp.
PAD -20: Toggle to apply 20dB of attenuation to the input signal
• Applies to the HI-Z and MIC inputs
• Illuminates when engaged
