The EAR 824 Mic Pre is a versatile device for use as an upgrade from standard mic amps or as a level booster and line driver for use with any microphone. Power is available as either 48V phantom powering or as other optional configurations including 130V for the B&K line of mics.   With the optional EAR matching transformer ribbon microphones can also be accommodated.  Gain is switchable from 16dB to 60dB in 4 dB steps (2 dB steps available as an option) to cover all applications.

Onboard M/S decoding can be provided as a custom order.  Output is balanced via a wideband transformer with impedance suitable for driving long lengths of high-grade cable.

This amplifier enables the user to extract the maximum from any microphone with the minimum of signal degradation.  A fully thought out product rather than an afterthought as often provided by microphone manufacturers, it applies the same expertise in audio amplifiers as has made the EAR power amplifiers famous.

Specifications:
Input impedance: 600 ohms (standard phantom power version)
Output impedance: 650 ohm, balanced and floating
Maximum output level @ 1% distortion: +26dBm into 600 ohms
Microphone power: up to 7mA available per microphone
