HAD-48
DYNAMIC MIC
PREAMP

Pre-Amp for Dynamic Microphone

Because dynamic microphones have lower output levels than condenser microphones, long cable lengths often result in a noticeably noisy signal. Sanken’s innovative HAD-48 microphone preamplifier solves this problem by increasing the microphone level considerably with no degradation of signal.

Providing a choice of switchable 20dB or 40dB of gain, this greatly improves the signal-to-noise ratio. Even when using dynamic microphones and long cables between the mic and the input of the mixing console, this level boost can help overcome line loss and diminished frequency response. Additionally, increased noise due to added gain in the microphone preamp can be reduced.

The HAD-48 features an XLR-style barrel (XLR-3M – XLR-3F) just 105.3mm long. No batteries are needed, because the HAD-48 runs off 48V phantom power from the mixer input and draws a mere 3mA. The phantom power does not pass through to the microphone, eliminating voltage concerns of the microphone.
