The APT20 is a phantom power supply unit for use with two condenser microphones. It supplies 48 V DC to the microphones and routes the signal to a mixer or microphone amplifier. It features XLR connections for in- and output, and at the back is an euro power connection with power switch provided.

The K6P powering module is at the heart of Sennheiser's professional modular
condenser microphone system. It is similar to the K6 powering module but is
powered by 12 - 48 V phantom power only, for use where battery power is not
required (e.g. permanent installations). The K6P can be combined with various
microphone heads to produce microphones with a variety of pick-up patterns.
Matt black, anodised, scratch-resistant finish.

Alctron PS200 Portable 48V Phantom Power Supply for Condenser Microphone Live Broadcast Mic Power Supply

The Radial SB-48 is a high performance phantom power generator that employs a non-radiating charge pump circuit to create a stable, ripple-free 48 volt supply for active direct boxes and condenser microphones. The stereo design features XLR inputs and outputs with a choice of 48V and 12V operation. The SB-48 is powered by a single 15VDC 400 milliamp supply that is included. The connector may be locked into place using a retention clamp. As with all Radial products, the SB-48 is manufactured in Canada from solid steel and powder coated for years of great looks!
