Shure RK-183 Phantom Preamplifier for MX183-184-185

Palmer Pan 48 is a unit for the external power supply of phantom powered appliances. Due to the high current level of a maximum of 20mA, the application is not just limited to condenser microphones. PAN 48 is excellent for supplying phantom powered active DI-boxes. The box has two channels. Specifications: 2 channels, each channel: Microphone input: XLR/f Pin 2 & 3 +48VDC, Pin 1 Ground Output: XLR/m no DC voltage Ground lift switch Phantom power stabilized ±5%. Low ripple, low noise Max. current 20mA totally. LED control. Metal casing 110x110x45mm

The challenge when using a condenser microphone with a preamp pedal, direct box or stage amp is that most of these only have unbalanced inputs. And as most phantom power supplies are only equipped with balanced inputs and outputs, making a proper connection is often difficult or impossible due to the impedance and level mismatch. 

The SB-48UB is a single channel phantom power generator that converts the power from a 15VDC supply to 48 Volts for use with a condenser microphone or active direct box. Inside, the SB48-UB converts the signal to both a lo-Z balanced XLR output and a hi-Z unbalanced ¼" out. Both outputs may be used concurrently whereby the XLR could feed the PA while the ¼" out could feed a stage amp or pedalboard
